What’s New 13

What’s New

OMEGAMON XE for DB2plex Version 220With Version 220, OMEGAMON XE for DB2plex includes all the functionality of OMEGAMON XE for DB2 Version 100. After installing OMEGAMON XE for DB2plex, you can view the workspaces, attributes, and situations that make up both products.

In addition, OMEGAMON XE for DB2plex significantly improves the navigation from workspace to workspace within data sharing groups. Previous versions of the product required you to start from the DB2plex Summary workspace, then right-click in a row of the DB2plex Summary table view. To navigate to an individual workspace group took several clicks of the mouse button.

You can now take advantage of the CandleNet Portal® interface by left-clicking directly on a specific workspace group.

OMEGAMON XE for DB2plex is such an agent.

An additional feature package, OMEGAMON DE is available with OMEGAMON XE. This feature package provides all the capability of OMEGAMON XE, plus additional capabilities as described later in this chapter.

What is CandleNet Portal?CandleNet Portal is a user interface that provides a birds-eye view of your enterprise that you can zoom into for a closer look. The 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. A CandleNet Portal table view is analogous to a CMW workspace.

Like the CMW, CandleNet Portal permits you to view the results of evaluating situations at regular intervals to check that your applications and system resources are 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.

Understanding OMEGAMON XE for DB2plex Attributes

Overview

In this unit you learn about the OMEGAMON XE for DB2plex attributes.

Using OMEGAMON XE for DB2plex attributes

OMEGAMON XE for DB2plex gathers data from remote agents residing on the managed systems of your DB2plex network and stores this data in system elements called attributes.

You can use OMEGAMON XE for DB2plex attributes to build situations that monitor the performance of your DB2plex network.

To use OMEGAMON XE for DB2plex attributes effectively, you must first understand the organization of an attribute.

� An attribute is made up of an attribute group and an attribute item.

� An attribute group refers to a unique characteristic of the data that is stored in the attribute.

� An attribute item stores data for a particular property of an attribute group.

Thus this example attribute

DB2_Lock_Conflict.Lock_Elapsed_Time

comprises an attribute item, Lock_Elapsed_Time, that stores lock elapsed time data for the attribute group DB2_Lock_Conflict.

For more information on attributesSee the online help for OMEGAMON XE for DB2plex for a complete description of each of the attribute groups and its attributes.

Understanding OMEGAMON XE for DB2plex Information

Understanding OMEGAMON XE for DB2plex Information

OverviewIn this unit you learn about the information OMEGAMON XE for DB2plex provides. OMEGAMON XE for DB2plex information is displayed in CandleNet Portal® in named workspaces. Within a given workspace, information may appear in tabular form. 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.

Using OMEGAMON XE for DB2plex informationOMEGAMON XE for DB2plex provides the ability to view information about each DB2plex managed system that you are monitoring. You can use this information to

� monitor the performance of each DB2plex managed system, helping you to identify system bottlenecks and evaluate tuning decisions.

� select the most effective threshold values for situations you create.

� review status information when a change in the state of a given resource occurs, such as from OK to Warning or Warning to Critical.

Associating OMEGAMON XE for DB2plex workspaces with attributesThere is a direct relationship between OMEGAMON XE for DB2plex attributes and workspaces. An attribute group corresponds to a workspace and attribute items correspond to workspace columns.

For example, the Global Lock Conflicts workspace contains information that is collected in and represented by the DB2_Lock_Conflict attribute group. The DB2_Lock_Conflict.Lock_Elapsed_Time attribute item contains the information that is displayed in the Elapsed Time workspace column.

Each workspace displays real-time information for many of the DB2plex attributes. The DB2plex workspaces are available to you, independent of whether you are using OMEGAMON XE for DB2plex to monitor situations.

Understanding OMEGAMON XE for DB2plex Situations and Events

Understanding OMEGAMON XE for DB2plex Situations and Events

OverviewIn this unit you learn about OMEGAMON XE for DB2plex situations that are shipped with the product. When using CandleNet Portal, you will see these referred to as predefined situations.

Situations and EventsA situation describes a condition you want to test. OMEGAMON XE for DB2plex compares the situation with the values collected by the monitoring agent and raises an event if the condition is met.

Every Candle agent comes with a set of predefined situations so you can begin monitoring as soon as you start using OMEGAMON XE for DB2plex. You can edit these situations to match your environment or create your own. You can read a situation as, “If this condition exists, then the situation is true”.

Associated with every situation is an event indicator. When the condition described in the situation becomes true, the event is raised. Event indicators can be critical, warning, or informational. A user monitoring the network for events can acknowledge an event to indicate it has been seen and the problem is being addressed.

Using OMEGAMON XE for DB2plex situationsYou can use the OMEGAMON XE for DB2plex situations shipped with the product

� to begin monitoring your DB2plex-managed systems immediately� as models for creating your own situations� to monitor and manage, through localized automation, widely dispersed

resources

You can modify the situations you receive to contain values more appropriate for your system. However, Candle recommends that before changing these situations, you make a copy and keep that copy unmodified so that you can revert to the original situations should the need arise.

Most of the OMEGAMON XE for DB2plex predefined situations have an alert status of either Critical or Warning.

Information about OMEGAMON XE for DB2plex SituationsFor more information on predefined situations, see the product’s online help.

Using CandleNet Portal to Work with Workspaces

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 CandleNet Portal application window at one time. To open the default workspace, in the Navigator, click the item name or its icon.

Opening multiple workspaces

CandleNet Portal enables you to have multiple workspaces for an item. 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, 10, 15, 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 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 refreshes use system resources. You can control when the views are refreshed by suspending the refresh. You

Using CandleNet Portal to Work with Workspaces

30 OMEGAMON XE for DB2plex User’s Guide, V220

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 a CandleNet Portal workspace.

Editing a workspaceYour CandleNet Portal product 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:

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

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

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

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

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

� 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.

Using CandleNet Portal to Work with Workspaces

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 (modified) workspace in the text box and click OK. The name you specify must not be the same as the name of the predefined workspace that you modified.

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 CandleNet Portal user ID. Users with a different ID will not see your changes. If you have edited the workspace but do not 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.

� You can link from one workspace to another from the Navigator. Simply right-click on a workspace. In the pop-up window that appears, select the workspace to which you want to link.

� 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.

� When a link is predefined for a row in a table view, an icon appears to the left of each row in the table. (The icon resembles two links in a chain.) When the icon is not shaded out, the link is valid for the row. The user can left-click the icon to navigate instantly to the next workspace.

Right-clicking on the icon causes a pop-up menu to appear, showing all the links defined for the row. From this menu, you can select from the list of links or change the default link.

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).

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

Using CandleNet Portal to Work with Workspaces

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.

Filtering informationFiltering of OMEGAMON XE for DB2plex information is accomplished in CandleNet Portal by linking from rows within the summary table view at the highest level of the workspace hierarchy to progressively lower-level workspaces. To link from a specific row, right-click within any cell in the row, 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 row of a table view.

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.

To manually set up filtering for a given table view, 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 to determine which rows to display. To save your filtering specifications, you must save the workspace before exiting.

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. However, if you deselect the Run at startup box, the situation will be saved but not started.

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.

Using CandleNet Portal to Navigate Between Workspaces

42 OMEGAMON XE for DB2plex User’s Guide, V220

Using CandleNet Portal to Navigate Between Workspaces

OverviewThe CandleNet Portal navigation tree (or Navigator) is a hierarchy of the physical nodes and products installed in your enterprise. At the top of the hierarchy is the Enterprise, followed by the operating system (OS/390). The figure below shows the layout of the hierarchy.

There are three ways to navigate to a workspace. These are described below.

Select an entry in the navigation treeClick on the DB2plex entry in the Navigator to display the DB2plex Summary workspace, which lists the names of the DB2 subsystems being monitored. Each DB2 subsystem can be associated with either data sharing groups or DB2 instances. By expanding an instance of a data sharing group, the list of workspaces for that data sharing group appears. You can navigate to any of these workspaces directly.

Click on the Monitored Systems Summary workspace in the Navigator to display the highest-level workspace for OMEGAMON XE for DB2plex. From this summary workspace, you can drill down to lower-level workspaces and more granular details.

Select a workspace from the View > Workspace pull-downWorkspaces you have created have an entry in the View > Workspace pull-down menu. To navigate to these user-defined workspaces, click on a workspace name to select it from the pull-down menu.

Monitored Systems Summary Workspace 45

Typical Scenarios

Typical Scenarios

OverviewIn this unit we present several scenarios that describe how you can use the Monitored Systems Summary workspace.

Scenario 1: Determine availability of individual DB2 systems for a data sharing group

You can use the Monitored System Summary workspace to verify that all DB2 subsystems defined as part of the data sharing group are currently active and being monitored.

For example, you can use the workspace threshold capabilities to highlight cases where the number of active DB2 systems is lower than the expected number.

Access the Monitored System Summary workspace. Notice that the second column (immediately following the data sharing group name) contains the count of DB2 systems currently connected to the data sharing group. Use the Properties page for the workspace and select the Threshold tab. On the first threshold line, enter the name of the data sharing group under the column “Subsystem or Group Name” and set the condition to ““EQ”. On the same line, enter the number of DB2 systems normally connected to this data sharing group under the “DB2 Count” column and set the condition on this column to “LT”. If monitoring more than one data sharing group, you can repeat these steps on the next line. Press OK to end the Properties dialog; then save the workspace. The next time the workspace is displayed, OMEGAMON XE for DB2 will highlight the condition if the current count of DB2 systems connected does not match the expected count for each data sharing group.

Note: The count of DB2 systems is only accurate if the Candle-provided monitoring agent for the DB2plex product is running on all MVS images where DB2 subsystems are running.

Scenario 2: Determine if there are any global problems within a data sharing group

You can use the Monitored System Summary workspace to determine whether any threads within a data sharing group are waiting for locks .

Access the Monitored System Summary workspace. If the Lock Conflict Count field contains a number greater than zero, at least one thread within the data sharing group is waiting on a lock. If this condition persists, you can use the Global Lock Conflicts workspace to determine who is waiting on a lock and which thread within the data sharing group currently holds the lock.

Global Lock Conflicts Workspace 57

Typical Scenarios

Typical Scenarios

OverviewIn this unit we present several scenarios that describe how you can use the Global Lock Conflicts workspace.

Scenario 1: Identifying global database lock conflictsYou can use the Global Lock Conflicts workspace to monitor identify global database lock conflicts between two or more DB2 subsystems. For example, you may want to identify database lock conflicts that exist between two or more DB2 subsystems in a data sharing group.

Access the Global Lock Conflicts Workspace. Notice that the workspace displays locking data for application threads, uniquely identifying each application thread by DB2ID, plan name, and correlation identifier.

To see the Lock Status and Thread Status columns, scroll to the right. Identify threads with a WAIT_GLBLOCK thread status and a WAITER lock status. If a thread’s status is WAIT_GLBLOCK, a global lock conflict exists between this thread and a thread on another DB2 subsystem in the same data sharing group.

Identify all threads on other DB2 subsystems that have an OWNER lock status. To see the Lock Resource column for all threads, scroll to the left. When there are threads on two different DB2 subsystems that are both referencing the same lock resource, a database lock conflict exists between the two DB2 subsystems.

Scenario 2: Investigating a true database lock situationYou can use the Global Lock Conflicts workspace to investigate a database lock situation, viewing locking data for one or more application threads that caused a situation to evaluate to true.

For example, you may want to investigate the predefined situation DB2_Lock_Waiter_Time_Critical, which evaluates to true when lock elapsed time is greater than 10 seconds and lock status is Waiter.

Access the Global Lock Conflicts Workspace. Filter the workspace to show only those transactions with a lock elapsed time greater than 10 seconds. On the filtered workspace, identify all transactions with a Waiter lock status.

Typical Scenarios

Typical Scenarios

OverviewIn this unit we present several scenarios that describes how you can use the workspaces in the Group Buffer Pool Statistics workspace group.

Scenario 1: Monitoring the group buffer poolsIf response time suddenly slows or if a situation is triggered against one of the buffer pool components contained within the workspace, the workspace will allow you to determine if your group buffer pools are performing as designed. If they are not performing properly after modifying the DB2 parameters, then you can use this workspace to verify that the buffer pool values are correct and that the buffer pools are working after the modifications have been made.

Scenario 2: Load balancingIf load balancing appears to be a problem, the Detailed Group Buffer Pool Statistics workspace can provide helpful information. When a large percentage of the activity to a buffer pool consistently comes from a single DB2 system, you can identify that fact by analyzing the nature of the read and write activity involving a specific buffer pool.

Armed with the details about which DB2 system is monopolizing the buffer pool, you can yield some performance improvement by offloading some of the activity to a different DB2 system.

Typical Scenarios

Typical Scenarios

OverviewIn this unit we present several scenarios that describe how you can use the workspaces in the Group Buffer Pool Structures workspace group.

Scenario 1: Monitoring group buffer pool structuresYou can use the Group Buffer Pool Structures to monitor group buffer pool structures and to track structure utilization over a period of time.

For example, you may want to monitor group buffer pool structures with a low read hit percent, to determine if you need to expand the size of the group buffer pool. The optimal read hit percent is greater than 80 percent.

Access the Group Buffer Pool Structures. Notice that, by default, the workspace sorts in alphabetical order by structure name. To see the Read Hit Percent column, you may need to scroll to the right.

To track the structure read hit percent over a period of time, update or refresh the structure data on the Group Buffer Pool Structures by clicking Refresh Now on the View pull-down menu. The Group Buffer Pool Structures redisplays with the most current data available from the Candle Management Server (CMS).

Scenario 2: Investigating a true group buffer pool situationYou can use the Group Buffer Pool Structures to investigate a group buffer pool situation, viewing detailed data for group buffer pool structures that caused a situation to evaluate to true.

For example, you may want to investigate the predefined situation DB2_Group_BP_Read_Hit_Warning, which evaluates to true when Read Hit Percent is in the range of 60 to 80 percent.

Access the Group Buffer Pool Structures. To see the Read Hit Percent value for each group buffer pool structure, you may need to scroll to the right.

Note: You can continue your investigation of a group buffer pool structure by accessing a host session from CandleNet Portal to review an OMEGAMON II host session.

Typical Scenarios

OverviewIn this unit we present scenarios that describes how you can use the workspaces in the GOA Volume workspace group.

Scenario 1: Identifying objects with excessive I/O activity You can use these workspaces to determine DASD contention between multiple objects (such as multiple databases and multiple volumes).

For example, you can create a situation to monitor for excessive I/O activity and then use the workspace to identify the volume. Once the volume has been identified, you can take action to eliminate the problem by load balancing or dataset movement.

Scenario 2: Identifying bottlenecks caused by non-DB2 activityPerformance bottlenecks can be attributed to DB2 activity or to non-DB2 activity for a particular volume. With the GOA Volume workspace group, you have access to details that allow you to identify potential bottlenecks caused by non-DB2 activity.

OverviewIn this unit we present a scenario that describes how you can use the workspaces in the GOA Volume Thread workspace group.

Scenario: Finding bottlenecks on a volumeYou can use this workspace to identify potential bottlenecks on a volume.

For example, when too many threads attempt to access the same volume concurrently, the potential exists for a performance bottleneck. To investigate this possibility, you can evaluate which volumes currently have high DB2 thread activity. When you have determined which volumes are affected, you can drill down to obtain the details on which threads are generating the activity. You can then take corrective action to move these databases to separate volumes.

DB2 Command Situation Definitions

OverviewIn this unit you can view information about the DB2 Command predefined situations. These situations are identical to other predefined situations with one exception: when a DB2 Command situation proves true, a message is automatically sent to a specified user. You must identify to OMEGAMON XE for DB2plex the name of the specified user who will receive these messages.

The relationship between each DB2 Command situation and its comparable associated situation is

DB2_CMD_Connection_FailedMonitors the status of connections to coupling facility and group buffer pool structures, detecting a warning condition when Connection_Status is equal to FAIL.

Formula:

If Group_Buffer_Pool_Connections.Connection_Status = FAIL

When this situation proves true, OMEGAMON XE for DB2plex automatically sends a message to a user, identifying the fact that data sharing is not active for the DB2 system.

Workspaces

IntroductionThis appendix contains a table that identifies, by name, the predefined workspaces supplied with DB2plex when using Candle Management Workstation versus the predefined workspaces supplied with DB2plex when using CandleNet Portal®. For the workspaces identified by type Link, you can access them from a workspace at a higher level in the workspace hierarchy. By doing so, the filtering by DB2 subsystem remains in effect.

Base Maintenance Plan

134 OMEGAMON XE for DB2plex User’s Guide, V220

Base Maintenance Plan

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.

Guide to Candle Customer Support 135

Base Maintenance Plan

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. Customers set their own Severity Levels when contacting a support center. This ensures that we respond according to your individual business requirements.

Severity 1 Crisis

A crisis affects your ability to conduct business, and no procedural workaround exists. The system or application may be down.

Severity 2High

A high-impact problem indicates significant business effect to you. The program is usable but severely limited.

Customer Support EscalationsCandle Customer Support is committed to achieving high satisfaction ratings from our customers. However, we realize that you may occasionally have support issues that need to be escalated to Candle management. In those instances, we offer the following simple escalation procedure:

If you experience dissatisfaction with Candle Customer Support at any time, please escalate your concern by calling the Candle support location closest to you. Ask to speak to a Customer Support manager. During standard business hours, a Customer Support manager will be available to talk with you or will return your call. If you elect to hold for a manager, you will be connected with someone as soon as possible. If you wish a return call, please tell the Candle representative coordinating your call when you will be available. After contacting you, the Customer Support manager will develop an action plan to resolve your issue. All escalations or complaints received about support issues are logged and tracked to ensure responsiveness and closure.
