OMEGAMON XE for Oracle Operating Environment



Overview

OMEGAMON XE for Oracle can help you to address the increasing challenges presented by today’s technical environment. In this unit you learn about the operating environment in which OMEGAMON XE for Oracle resides.

What is OMEGAMON XE?OMEGAMON XE is a suite of products that assists you in monitoring your mainframe and distributed systems on a variety of platforms using a variety of workstations.

It provides a way to monitor the availability and performance of all the systems in your enterprise from one or several designated workstations. It provides many useful reports you can use to track trends and understand and troubleshoot system problems. You can use OMEGAMON XE to

n establish your own performance thresholds

n create situations, which are conditions to monitor

n create and send commands to systems in your managed enterprise by means of the Take Action feature. Take Action enables you to, for instance, restart a process that is not functioning properly or send a message

n create comprehensive reports about system conditions

n monitor for alerts on the systems and platforms you are managing

n trace the causes leading up to an alert

n define your own queries, using the attributes provided by OMEGAMON XE for Oracle, to monitor conditions of particular interest to you



Components of the environmentThe client-server-agent implementation includes

n a client, that can be

– a CandleNet Portal workstation

– a Candle Management Workstation® (CMW™), used primarily for performing user administration tasks

n a server, known as the Candle Management Server ® (CMS™)

n a CandleNet Portal server that performs common CandleNet Portal functions and serves to lighten the CandleNet Portal client

n monitoring agents that collect and distribute data to a CMS. The OMEGAMON XE for Oracle is such an agent.

Two additional feature packages are available with OMEGAMON XE. These are OMEGAMON DE and OMEGAMON DE Policy Management. Each of these feature packages provides all the capability of OMEGAMON XE, plus additional capabilities: The additional capabilities provided by OMEGAMON DE and OMEGAMON DE Policy Management are described later in this chapter.

What is CandleNet Portal?CandleNet Portal is the user interface into your OMEGAMON XE product set. It provides a view of your enterprise from which you can drill down to more closely examine components of your systems environment. Its application window consists of a Navigator that shows all the systems in your enterprise where Candle agents are installed, and a workspace that includes table and chart views of system and application conditions.

CandleNet Portal runs situations at regular intervals to check that your applications and system resources are running, and running well. A failed test causes event indicators to appear in the Navigator.

CandleNet Portal offers two modes of operation: desktop and browser. In desktop mode, the application software is installed on your system. In browser mode, the system administrator installs the application on the web server and you start CandleNet Portal from your browser. In browser mode, the software



is downloaded to your system the first time you log on to CandleNet Portal, and thereafter only when there are software updates.

What is the Candle Management Workstation?When using OMEGAMON XE for Oracle, you use the Candle Management Workstation (CMW) to perform user administration functions.

Further Information about the CMW and CandleNet PortalFor further information about CandleNet Portal, refer to the product’s online Help and to Administering OMEGAMON Products: CandleNet Portal.

Further information about using the CMW for user administration can be found in the Candle Management Workstation Administrator’s Guide as well as in the CMW online Help.

If you are an experienced CMW user, you should review the CandleNet Portal help topic called “CMW Users.” This topic addresses the similarities and differences of these user interfaces, provides guidance about each interface’s functionality, and a cross-reference listing that clarifies the products’ terminology.

What is OMEGAMON DE?The OMEGAMON DE feature package for CandleNet Portal offers a dashboard view of your enterprise. This feature provides a single point of control from which you can manage the resources your business-critical applications rely on, including a range of operating systems, servers, databases, mainframes, and Web components. It enables you to pull together the data and functionality built into all the Candle monitoring solutions, such as OMEGAMON XE for Oracle. OMEGAMON DE provides all the capability of OMEGAMON XE, plus these additional capabilities:

n You can display multiple applications in one workspace.

In a single workspace, you can build a table or chart with data from one type of monitoring agent, and another table or chart with data from a different agent. Within that workspace, you can show views from as many different agent types as are included on that branch of the Navigator.



n You can link application workspaces

You can define a link from a workspace associated with one type of monitoring agent to a workspace associated with another type of agent.

n You can define enterprise-specific Navigator views

The Navigator physical view shows the hierarchy of your managed enterprise by operating platform and type of Candle agent. The Navigator business view shows the hierarchy of any managed objects defined through the CMW. You can also define Navigator views for any logical grouping, such as a departmental or site hierarchy.

n You can define a graphic view

The graphic view enables you to retrieve and display real-time monitoring data from Candle agents. Using the graphic view, you can create a background image or import one, then place objects (Navigator items) on the image or have it done automatically using geographical coordinates. You can zoom in and you can add such graphics as floor plans and organization charts.

n You can integrate information provided by Candle’s Universal Integrator

Candle’s Universal Integrator is an agent you can configure to monitor any data you collect. It lets you integrate data from virtually any platform and any source, such as custom applications, databases, systems, and subsystems. Your defined data providers are listed in the Navigator, and default workspaces are automatically created.

Detailed information about OMEGAMON DE is provided in the CandleNet Portal online Help.

About OMEGAMON DE Policy Management and the Workflow EditorOMEGAMON DE Policy Management incorporates all of the features of OMEGAMON XE and adds automation capabilities. The Workflow Editor enables you to design sets of automated system processes, called policies, to resolve system problems. A policy performs actions, schedules work to be performed by users, or automates manual tasks.

OMEGAMON XE for Oracle



OverviewThis topic describes OMEGAMON XE for Oracle and the benefits it can provide to your organization.

Using OMEGAMON XE for Oracle and CandleNet Portal Interface As part of the OMEGAMON XE for Distributed Systems, OMEGAMON XE for Oracle offers a central point of management for distributed databases. It provides a comprehensive means for gathering exactly the information you need to detect problems early and to prevent them. Information is standardized across all systems, and you can monitor hundreds of servers from a single workstation. OMEGAMON XE lets you easily collect and analyze specific information.

OMEGAMON XE for Oracle is an intelligent, remote monitoring agent that resides on managed systems. It assists you in anticipating trouble and warns systems administrators when critical events take place on their systems. With OMEGAMON XE for Oracle, database and systems administrators can set threshold levels and flags as desired to alert them when the system reaches these thresholds.

In the CandleNet Portal interface, information appears in named workspaces. Within a given workspace, information may appear in tabular form similar to the reports displayed by Candle Management Workstation. CandleNet Portal refers to this tabular format for information as a table view. Information may also be displayed in the workspace as charts, graphs, or other formats you can specify.



How OMEGAMON XE for Oracle assists you An OMEGAMON monitoring agent provides several benefits. It can

n Simplify application and system management — by managing applications, platforms, and resources across your environment.

n Increase profits —by providing you with real-time access to reliable, up-to-the-minute data that allows you to make faster, better-informed operating decisions.

n Scale and port to new platforms —by supporting a wide variety of platforms.

n Improve system performance —by letting you integrate, monitor, and manage your system, network, console, and mission-critical applications. An OMEGAMON monitoring agent can alert the Candle Management Server (CMS) and the Candle Management Workstation (CMW) when conditions on the system network meet threshold-based conditions. These alerts notify your systems administrator to limit and control database usage. You can view data gathered by an OMEGAMON monitoring agent in tables and charts for the status of your distributed database systems.

n Enhance efficiency —by monitoring diverse platforms and networks from a single PC screen. Depending on your configuration, you can collect and monitor data across platforms. OMEGAMON monitoring agents gather and filter status information at the managed system rather than at the hub, eliminating unnecessary data transmission and sending only data that is relevant to changes in status conditions. OMEGAMON XE for Oracle helps you monitor and gather the consistent, accurate, and timely information you need to effectively perform your job.



Advanced monitoring facilities OMEGAMON XE for Oracle includes advanced monitoring facilities:

n user-defined and predefined situations based on thresholds to raise different types of alerts: critical, warning, and other

n at-a-glance status picture of all database servers

n the capability to monitor multiple servers simultaneously from one or more centralized workstations, including servers on various platforms running an Oracle database management system

Planning and installationFor information on planning and installing your OMEGAMON XE for Oracle, refer to the installation documentation that was sent with your product.

Features to facilitate database managementThe OMEGAMON XE for Oracle includes the following features that facilitate database management:

n support for Oracle database management system

n the ability to create situations from attributes

n historical data collection for long-term trending

n the ability to determine whether the problem being monitored is related to SQL

n the ability to check for a particular situation and, if found, to page someone or send a UNIX mail note (reflex automation)

n predefined situations and templates

Historical Data CollectionYou can use the facilities of CandleNet Portal’s historical data collection function to store and save the data being collected by your OMEGAMON XE



for Oracle agent or agents. The historical data collection function permits you to specify

n the attribute group or groups for which data is to be collected

n the interval at which data is to be collected

n the interval at which data is to be warehoused (if you choose to do so)

n the location (either at the agent or at the CMS) at which the collected data is to be stored

Information about using the Historical Data Collection function can be found in the CandleNet Portal online Help and in the Historical Data Collection Guide for OMEGAMON XE and CandleNet Command Center.

Predefined Situations


Predefined Situations

Candle minimizes your programming requirements by providing you with predefined situations that you can use to start monitoring your system immediately. There are two types of predefined solutions: n Situations in which monitoring criteria are set for the performance of your

systems n Templates in which managed objects representing various areas of your

system are correlated with situations and status states

Using predefined situations for turn-key performance Candle provides you with situations tailored to the OMEGAMON XE for Oracle that you can employ without first having to create them. You can activate these situations to solve common problems such as n CPU Utilization—Used by the operating system to establish priorities in

the system. High values indicate that a process may be CPU bound or doing very little I/O.

n System Free Memory—One indicator that the system is busy. n Wait I/O—Can indicate the system is busy and may be in trouble if the

Wait I/O is too large. n System Idle CPU—Often indicates the system is busy if the CPU idle

indicator is less than 10%. n System Wait I/O—Indicates whether the system has excessive paging

activity or other disk activity.

You can also modify predefined situations to suit your specific needs, and you can create new situations.

See the Administering OMEGAMON Products: CandleNet Portal for complete instructions on creating and using situations to monitor your distributed database system.

For more information on predefined templates Candle provides predefined templates for UNIX systems. See Administering OMEGAMON Products: CandleNet Portal for instructions on using the predefined templates for your system.

Understanding Attributes



OMEGAMON XE for Oracle gathers data from remote agents and data collectors that reside on the managed systems in your enterprise. It then stores this data in system elements called attributes.

You can use these attributes to create custom situations to monitor the performance of the managed databases in your enterprise.

Attribute structureTo use attributes effectively, you must first understand the structure of an attribute.

n An attribute is an item that helps you monitor situations in your enterprise.

n Each attribute belongs to an attribute group. The attribute group includes attributes that are related.

n Each attribute item stores data for a particular property of an attribute group.

Examples of attributes and attribute groupsThe following example gives an attribute that stores data about the amount of free space in a database.

n For OMEGAMON XE for Oracle, the DB_Percent_Free _Space is an attribute in the Oracle_Database group.

This attribute group contains other attributes that relate to managing and monitoring databases.



Understanding the attribute and workspace relationshipA direct relationship exists between the attributes and workspaces for OMEGAMON XE for Oracle. Each attribute group is associated with one or more workspaces. The attributes in an attribute group correspond to columns in the table views. These tables monitor activity for your distributed databases.

For example, the Oracle_Database attribute group contains attributes that provide data for the Oracle Database workspace.

Using workspacesSee“Working with Workspaces” on page 28 for basic information on using workspaces. For detailed information, refer to the Candle Management Workstation User’s Guide.

Working with Workspaces



This unit provides a high-level overview of working with workspaces while using the CandleNet Portal interface. For the most current in-depth information, refer to the online help provided with CandleNet Portal.

The workspace is the working area in which CandleNet Portal presents information. As you select items, the workspace presents views pertinent to your selection. Each workspace has at least one view.

Every workspace has a set of properties associated with it. You can customize the workspace by working in the Properties editor to change the style and content of each view. Be aware that the changes you make to the workspace are lost when you switch to another workspace unless you save them first.

Another way to customize the workspace is to change the type of view or to add views to the workspace.

Formats for informationOMEGAMON XE for Oracle information can be presented to you in any of the views below:

n Table viewn Pie chart viewn Bar chart viewn Plot chart viewn Needle gauge viewn Thermometer gauge viewn Notepad viewn Event console view, which shows the status of the situations associated

with the system. n Take Action view, which is used to send a command to the system. n Terminal view, which enables you to start a 3270 or 5250 work session. n Browser view, which permits you to open a browser to see HTML pages

and Web sites.



Opening a workspace

Opening the default workspace

Most items in the Navigator have a default workspace associated with them. Some items have multiple workspaces you can open, although only one workspace can be open in the application window at one time. To open the default workspace, in the Navigator, click the item name or its icon.

Opening multiple workspaces

Each Navigator item can be associated with multiple workspaces. If the Navigator item has more than one workspace associated with it, use View > Workspace to see and select from a list of alternate workspaces.

Refreshing or reloading a workspaceOnce a workspace is open, it is not refreshed automatically. Rather, CandleNet Portal refreshes the table and chart views in the workspace only when you manually request they be refreshed or when the workspace is reloaded. You can, however, choose to automate the refresh at specified intervals. When choosing automatic refresh for a workspace, you should consider the impact of the refresh on system resources.

To define automatic refresh for a workspace:

1. Open the View menu, then point to Refresh Every.

2. Click 5, 15, or 60 minutes; 30 or 60 seconds; or On Demand.To refresh a workspace manually with the latest information, click Refresh.

To manually reload the saved workspace and refresh the monitoring data, click Reload. Note that, if you made any changes to the workspace properties without saving them, the changes will be lost when a reload occurs.

Suspending or stopping a workspaceCandleNet Portal interface receives monitoring data from the agents at timed intervals and, if you have defined automatic refresh for the workspace, refreshes the table and chart views in the workspace. The refresh process uses system resources. You can control when the views are refreshed by



suspending the refresh. You can also stop loading the workspace if it is not what you want or you plan to change it.

To stop refreshing, click Suspend. You can then manually refresh the workspace, or you can click Resume to resume automatic refresh.

To stop loading a workspace, click the CandleNet Portal Stop icon. Note that clicking your browser’s Stop icon will not stop the loading of an OMEGAMON XE workspace.

Editing a workspaceOMEGAMON XE for Oracle comes with a set of predefined workspaces for every item in the Navigator's physical map. You can edit any of these workspaces to suit your environment.

The changes you can make to a workspace include the following:

n Split a view horizontally or vertically into two separate views.

n Change the dimensions of the views by dragging the borders between them.

n Change a view to a different type, such as from a pie chart to a thermometer gauge.

n Edit the properties of any view to change the data displayed and how the view is styled.

n Build a link to another workspace so that you can link to the other workspace from this one at any time.

n Remove a view from the workspace. The adjacent view enlarges to fill the gap.

When you are finished editing a workspace you must save your changes either as the current workspace or as a new workspace. If you do not save your changes, they will be lost when you open another workspace or end your work session.

Any changes you make to a workspace are available to all other users on the network having the same ID.



Saving the workspaceWhatever changes you make to the workspace properties, such as adding or editing a view, are only temporary. They will be lost when you open another workspace or exit CandleNet Portal, unless you save the workspace. You can also save multiple workspaces for the same Navigator item.

Click Save to replace the original workspace with the current workspace. If you do not want to replace the original workspace, save the current workspace under a new name.

If this is a new workspace:

1. Open the File menu and select Save Workspace As.

2. Type a name for the new workspace in the text box and click OK.Result: The workspace is saved with the name you specify, and is available to all of your managed systems of the same managed system type.

Note: The saved workspace is associated with your user ID. Users with a different ID will not see your changes. If you have edited the workspace but don’t want to save your workspace, you can reload the saved workspace as described on page 29.

Linking workspacesSome of your product’s predefined workspaces may be linked to other related workspaces. Linking workspaces is a quick method for going from one workspace to another related workspace quickly.

n You can link from one workspace to another from the Navigator. Simply right-click on a workspace and then select the workspace to link to from the pop-up menu that is presented.

n While using a workspace’s table view, you can right-click within a cell in the table to display existing links to other related workspaces.

You can define your own links using the Link Wizard by following the directions in CandleNet Portal’s online help. Once a link is defined, you can link to the subject workspace from another workspace, edit the link, or remove a link definition. Note that the link will not be saved until the subject workspace is saved.



Defining workspace propertiesEvery workspace has properties for its views. You can right-click in an open view or any item in the Navigator to select and open the Properties editor. The Properties tree has a Views folder with folders for each type of view in the workspace. To edit the properties of a view, click its icon in the Properties tree.

The properties open in the right frame with some or all of the following tabs:

Opening an event workspaceWhen the conditions of a situation have been met, an event indicator appears in the Navigator. You can investigate the event by opening its workspace.

1. In the Navigator move the mouse pointer over the alert indicator to open a flyover listing of the event (or events if the item has more than one true situation).

2. In the flyover listing click a situation name to open its workspace.Result: The Navigator moves to the event location and shows the situation name, and its event workspace opens.

The event workspace shows two table views, one with the values of the attributes when the situation fired, and the other with their current values. It can also display a text view with any expert advice written by the situation’s author, and the Take Action view so you can send a command to the application started on that system.

Query Specify what data should go in the chart or table

Filters Refine the view by filtering out unwanted data from the chart or table

Thresholds Establish threshold values and color indicators for a table view

Configuration Specify the script to run or the connection to make whenever you open the terminal view

Style Change the behavior and appearance of the view



Filtering information

Pre-filtering

Filtering of OMEGAMON XE for Oracle information is accomplished by linking from cells within the summary table view at the highest level of the workspace hierarchy to progressively lower-level workspaces. To link from a specific cell, right-click within the cell, then select Link to from the pop-up menu that CandleNet Portal displays. Selecting Link to causes a list of lower-level workspaces to be displayed. Select the one you want from the list. You know you have reached the bottom of a hierarchical group if Link to does not appear in the pop-up menu when you right-click in a table view’s cell.

Similarly, you will not be given the opportunity to link to a workspace that does not contain any meaningful data. For example, Link to will not provide a link to the Database Locks workspace if the current row of the summary table has a lock count of 0.

Within a given workspace, the filtering criteria used to limit the data that is displayed are shown in the footer line of the workspace’s table view. As you navigate further down the hierarchy, the amount of information in the footer tends to increase.

Post-filtering

Post-filtering permits you to further reduce the number of rows being displayed as well as the columns that are displayed. To set up post-filtering, place the cursor on the table view, press the right mouse button, and select Properties. From the displayed dialog, select the Filters tab. Here you can select the columns to display as well as set up the criteria for which rows to display. To save your filtering specifications, you must save the workspace before exiting.

Sorting InformationSorting is handled by simply clicking on a column heading. Click once and the report will be sorted in ascending order. Clicking a second time will resort the report into descending order. A third click returns you to the report’s default sort.

Working with Situations



The Candle agent or agents that come with your OMEGAMON XE product have a set of predefined situations that you can use as-is or modify to meet your requirements. Candle suggests that if you choose to modify the predefined situations shipped with your product, you first make a copy to ensure fallback if necessary.

This unit provides a high-level overview of working with situations while using CandleNet Portal interface. For the most current in-depth information, refer to the online help provided with CandleNet Portal.

The Situation editorYou can display predefined situations and create your own situations using the Situation editor. The way to perform these functions is described below. The left frame of the Situation editor initially lists the situations associated with the Navigator item you selected. When you click a situation name or create a new situation, the right frame opens with the following tabs:

The Situation editor buttons let you Apply your changes by saving and starting the situation, and exit with (OK) or without (Cancel) saving your changes. Note that if you plan to edit multiple situations while in the Situation editor, click Apply after editing one situation to save your changes before selecting the next situation to edit (or creating a new one).

Create a situationYou can create and customize your own situations to monitor specific conditions in your enterprise.

Condition See, add to, and edit the condition being tested

Distribution See the systems to which the situation is assigned and assign the situation to systems

Expert Advice Write comments or instructions to be read in the event workspace

Action Specify a command to be sent to the system



1. Decide on which system you want the situation to run, then right-click either the name or icon of the system, agent, or attribute group in the Navigator.

2. Select Situations from the popup menu.

The Situation editor opens.

3. Click New Situation.

The Enter New Situation Name dialog opens.

4. Type a name for the situation and click OK.

The Select Attribute dialog opens.

5. Click a name in the Group list to see its attributes in the Item list.

6. Click an attribute name in the Item list, then OK.

The properties for the new situation display, with the attribute you just selected as the first column.

7. In the Condition tab, edit the condition, interval and status.

8. Click the Distribution tab to see and assign the systems to monitor.

9. Click the Expert Advice tab to enter text viewable from the event workspace.

10. Click the Action tab to enter a command to be invoked when the situation fires.

11. When you are finished creating the situation, click Apply to save your changes and start the situation; or, click OK to save your changes, start the situation, and exit the Situation editor.

The Situation editor checks the syntax of each expression you enter. If you enter an improper value for an attribute, such as "abc" for Disk Size, the cell turns red and the situation will not be saved until you correct the error.

Note:

n When you save a situation, it is stored on the Candle Management Server hub and is viewable at any other CandleNet Portal console whose CNP server is connected to the same CMS hub. The CNP server and CNP consoles must be recycled (restarted) before the situation can be observed from other consoles.



n In the unlikely event that two users attempt to save a situation with the same name simultaneously, an error will occur, ensuring that one situation does not overwrite another.

Display a situationTo examine the condition written for a situation, open it in the Situations editor. The editor has four tabs showing Condition, Distribution, Expert Advice, and Action for a given situation.

1. In the Navigator, right-click a system or any level below.You can right-click either the name or icon of a system, any of its Candle agents, or attribute groups. If you have already selected an event and opened its workspace, you can right-click the situation name.

2. Select Situations from the popup menu; or, if you right-clicked a situation name, click Edit Situation and skip step 3.The Situation editor opens. The Situation tree lists the situations for the object level chosen.

3. Click the situation to see its properties or, if you don’t see the situation in the tree, click the Situations Filter to see more.

Note: If you still do not see the situation you are looking for, click Cancel and locate the system to which the situation has been distributed. Then repeat these steps.

Edit a situationTo fine tune a situation, use the Situation editor to edit it.

1. In the Navigator right-click a system, agent, or attribute group.You can right-click either the icon or name of a system, any of its agents or attribute groups. If you have already selected an event and opened its workspace, you can right-click the situation name.

2. Click Situations from the popup menu; or, if you right-clicked a situation name, click Edit Situation and skip step 3.

3. Click Situations from the popup menu.The Situation editor opens. The Situation tree lists the situations for the level chosen.



4. Click a situation to see its properties, or, if you do not see the situation in the tree, click Situation Filter and select more options.

5. If you still do not see the situation you are looking for, click Cancel and locate the system to which the situation is distributed. Then repeat the previous steps.

6. On the Condition tab, edit the condition, interval, or status.

7. Click the Distribution tab to see and assign the systems to monitor.

8. Click the Expert Advice tab to enter text viewable from the event workspace.

9. Click the Action tab to enter a command to be invoked when the situation fires.

10. When you are finished editing the situation, click Apply to save your changes and start the situation; or, click OK to save your changes, start the situation, and exit the Situation editor.The Situation editor edits the syntax of each expression you enter. If you enter an improper value for an attribute, such as "30000" for % User Time, the cell turns red and the situation will not be saved until you correct the error.

Start, stop, or delete a situationWhenever you create or edit a situation, it starts running as soon as you click Apply or OK to close the Situation editor. You can stop and restart a situation at any time. Use Delete to permanently remove a situation.

Acknowledge an eventWhen the conditions of a situation are met, the situation becomes true and an event indicator appears over the system name and all related items in the Navigator. An event indicator is a colored icon that appears on top of a managed system’s icon in the Navigator and indicates a change in the status of a situation running on that managed system. You can investigate an event by opening its workspace. The Navigator shows only one event indicator for an item. If several situations have become True, the event indicator represents the situation that has the highest severity.



The event workspace for a situation contains four views to help you investigate the cause of an alert and take action if necessary:

You can create an acknowledgement to indicate that you have seen the event and have taken ownership of the problem. Raised events that show a blue checkmark in the Navigator have been acknowledged. You can clear the event by resetting the situation. However, when you reset a situation, you can no longer acknowledge it.

OverviewCandle offers a comprehensive Base Maintenance Plan to ensure that you realize the greatest value possible from your Candle software investments. We have more than 200 technicians providing support worldwide, committed to being responsive and to providing expedient resolutions to support requests. Technicians are available worldwide at all times during the local business day. In the event of an after-hours or weekend emergency, our computerized call management and forwarding system will ensure that a technician responds to Severity One situations within one hour. For customers outside of North America, after-hours and weekend support is provided in English language only by Candle Customer Support technicians located in the United States.

Telephone supportCandle provides consistently reliable levels of service—thanks to our worldwide support network of dedicated experts trained for specific products and operating systems. You will always work with a professional who truly understands your problem.

We use an online interactive problem management system to log and track all customer-reported support requests. We give your support request immediate attention by routing the issue to the appropriate technical resource, regardless of geographic location.

Level 0 Support is where your call to Candle Customer Support is first handled. Your support request is recorded in our problem management system, then transferred to the appropriate Level 1 support team. We provide Level 0 manual interaction with our customers because we support more than 170 products. We feel our customers would prefer personal interaction to a complex VRU or IVR selection menu.

Level 1 Support is the service provided for initial support requests. Our Level 1 team offers problem determination assistance, problem analysis, problem resolutions, installation assistance, and preventative and corrective service information. They also provide product usage assistance.



Level 2 Support is engaged if Level 1 cannot provide a resolution to your problem. Our Level 2 technicians are equipped to analyze and reproduce errors or to determine that an error is not reproducible. Problems that cannot be resolved by Level 2 are escalated to Candle’s Level 3 R&D support team.

Level 3 Support is engaged if a problem is identified in Candle product code. At Level 3, efforts are made to provide error correction, circumvention or notification that a correction or circumvention is not available. Level 3 support provides available maintenance modifications and maintenance delivery to correct appropriate documentation or product code errors.

eSupportIn order to facilitate the support process, Candle also provides eSupport, an electronic full-service information and customer support facility, via the World Wide Web at www.candle.com/support/. eSupport allows you to open a new service request and update existing service requests, as well as update information in your customer profile. New and updated service requests are queued to a support technician for immediate action. And we can respond to your request electronically or by telephone—it is your choice.

eSupport also contains a continually expanding knowledge base that customers can tap into at any time for self-service access to product and maintenance information.

The Candle Web Site and eSupport can be accessed 24 hours a day, 7 days a week by using your authorized Candle user ID and password.

Description of Candle severity levelsResponses to customer-reported product issues and usage questions are prioritized within Candle according to Severity Code assignment.
