Using This Tutorial 1-1

1Using This Tutorial

This chapter provides information that you need to know before using this tutorial.

Intended UsesThis tutorial is designed to be used in one of two ways:

■ As a quick overview of the steps needed to configure resources (such as single-instance databases, Oracle Forms Servers, Oracle Reports Servers, and Oracle HTTP Servers) to be highly available using Oracle Fail Safe

■ As a step-by-step introduction to using Oracle Fail Safe Manager

If you intend to use the tutorial this way, first ask your cluster administrator for at least five IP addresses that you can use on the cluster for virtual addresses. In addition, it is best to follow the lessons in order.

This tutorial provides the basic steps for configuring resources to make them highly available; it does not provide detailed information on the concepts behind high availability. You may find it helpful to refer to the Oracle Fail Safe Concepts and Administration Guide while using this tutorial.

Cluster SetupThis tutorial is intended to be run on a two-node cluster.

TerminologyThe following terminology is frequently used in this tutorial:

■ Cluster: A group of independent computing systems that operates as a single virtual system.

1-2 Oracle Fail Safe Tutorial

■ Failover: The process of taking cluster resources offline on one node and bringing them back online on another node. This process can either be planned (upgrades or maintenance) or unplanned (system failure).

■ Group: A logical collection of cluster resources that forms a minimal unit of failover. In a failover situation, the group is moved to a failover node. A group resides on only one cluster node at a time.

■ Resource: A physical or logical component that is available to a computing system. For example, disks, the network IP address, Forms Servers, Reports Servers, and Web servers are resources.

■ Virtual address: A network address at which the resources of a group can be accessed, regardless of the hardware server hosting those resources.

■ Virtual server: A group with one or more virtual addresses.

RequirementsThe following lists specify the requirements for the lessons of the tutorial. See the Oracle Fail Safe Release Notes for a list of supported software releases.

Creating a Sample Single-Instance Database■ A supported release of the Oracle database software is installed.

Creating and Adding a Forms Server and an Oracle HTTP Server to a Group■ Oracle9i Application Server is installed on both cluster nodes. (The installation

Invoking Oracle Fail Safe Manager and Verifying the Cluster 2-1

2Invoking Oracle Fail Safe Manager and

Verifying the Cluster

This chapter describes the steps necessary to invoke Oracle Fail Safe Manager and to verify the cluster.

Invoking Oracle Fail Safe Manager


2.1 Invoking Oracle Fail Safe ManagerTo invoke Oracle Fail Safe Manager from the taskbar, click the Start button, select Programs, then the Oracle home into which you installed Oracle Fail Safe Manager, then select Oracle Fail Safe Manager.

In this example, the Oracle home is Ofs.

Populating the Tree View


2.2 Populating the Tree ViewWhen you invoke Oracle Fail Safe Manager, the Manager opens and if no clusters have been added to the tree view previously, the Add Cluster to Tree dialog box opens. If this dialog box opens, enter the cluster alias of the cluster you want to manage. If the tree view is already populated, but the cluster you want to manage is not in the tree view, see Section 2.3.

Adding a Cluster to a Populated Tree View


2.3 Adding a Cluster to a Populated Tree ViewIf the tree view already contains a list of clusters, but not the one you want to manage, you can add a cluster to the populated tree view. On the File menu, select Add Cluster to Tree.

Using the Add Cluster to Tree Dialog Box


2.4 Using the Add Cluster to Tree Dialog BoxEnter the alias for the cluster that you want to manage in the Cluster Alias field, then click OK.

Connecting to the Cluster


2.5 Connecting to the ClusterAfter the tree view is populated with one or more cluster aliases, you must connect to the cluster or clusters before you can manage them with Oracle Fail Safe Manager.

In the tree view, select the cluster to which you want Oracle Fail Safe Manager to connect. Then, on the File menu, select Connect to Cluster. Oracle Fail Safe opens the Connect to Cluster dialog box.

Using the Connect to Cluster Dialog Box


2.6 Using the Connect to Cluster Dialog BoxEnter a user name and password for a domain account that has Administrator privileges on all nodes of the cluster to which you want to connect. Next, enter the account domain name. Select Save As Local Preferred Credentials if you want Oracle Fail Safe Manager to save the connection information in a file on the local system (the password will be encrypted). If you save local preferred credentials, the next time you open Oracle Fail Safe Manager, you can automatically connect to the cluster by expanding the tree view for that cluster.

Verifying the Cluster


2.7 Verifying the ClusterBefore beginning work with Oracle Fail Safe Manager, verify that the cluster hardware and software are correctly configured by using the Verify Cluster command.

If this is your first time using Oracle Fail Safe with this cluster, a window asking you to verify the cluster opens immediately after you connect to the cluster. To verify the cluster, click the Verify Cluster button.

If this is not your first time using Oracle Fail Safe with this cluster, on the Troubleshooting menu, select Verify Cluster.

Viewing the Results of the Verify Cluster Operation


2.8 Viewing the Results of the Verify Cluster OperationOracle Fail Safe displays the progress of the Verify Cluster operation.

Viewing the Results of the Verify Cluster Operation


Creating a Group 3-1

3Creating a Group

This chapter describes the steps necessary to create a group with Oracle Fail Safe Manager. Creating a group is the first step in making most resources (such as single-instance databases, Forms Servers, Reports Servers, and Oracle HTTP servers) highly available.

Invoking the Create Group Wizard


3.1 Invoking the Create Group WizardIn the tree view, select the cluster on which you want to create a group. Then, on the Groups menu, select Create to open the Create Group Wizard.

Naming and Describing the Group


3.2 Naming and Describing the GroupThe Create Group Wizard steps you through the process of creating a group. Enter FSTutorial as the name of the group, and if you want, enter a description of the group.

Specifying the Failback Policy


3.3 Specifying the Failback PolicyThe Failback policy determines whether a group that has previously failed over is returned to the node on which you prefer it to run when that node comes back online. Select "Allow failback." Then select "Fail back between" and enter 2 and then 3. This specifies that if a previously unavailable node comes back online, failback will be scheduled to occur between the hours of 2 a.m. and 3 a.m.

See the Oracle Fail Safe Concepts and Administration Guide for more information on the various failback policy options.

Specifying the Preferred Nodes


3.4 Specifying the Preferred NodesA preferred node is the node on which you want the group to run when all cluster nodes are running. When a previously unavailable node comes back online, the cluster software reads the preferred nodes list to determine if the group should be failed back to a preferred node. The first running node in the preferred nodes list is the one to which the group will fail back. If you do not specify a preferred nodes list, failback is disabled and the group will never fail back.

Move one of the nodes in the Available Nodes list to the Preferred Nodes list.

Finishing Creating a Group


3.5 Finishing Creating a GroupBefore the group is created, you have an opportunity to review the properties you have selected. If the properties are incorrect, click Cancel and then Back to make corrections. If the properties are correct, click OK, and Oracle Fail Safe will create the group.

Responding to the Virtual Address Question


3.6 Responding to the Virtual Address QuestionAfter creating the group, Oracle Fail Safe asks if you want to add a virtual address to the group. When a group contains a virtual address, the group is accessible by clients at the same network address, regardless of which cluster node is hosting the group.

If you click Yes, Oracle Fail Safe opens the Add Virtual Address Wizard immediately. Typically, you would click Yes. However, for the purposes of this tutorial, click No.

In Chapter 4, the tutorial will show you how to create a virtual address as a separate step.

Responding to the Virtual Address Question


Adding a Virtual Address to a Group 4-1

4Adding a Virtual Address to a Group

This chapter describes the steps necessary to add a virtual address to a group with Oracle Fail Safe Manager. Oracle Fail Safe Manager does not allow you to add any other resources (other than a generic service) to a group until at least one virtual address has been added to the group. Without a virtual address, clients cannot connect to resources that have been added to a group.

Opening the Add Resource to Group Wizard


4.1 Opening the Add Resource to Group WizardIn the tree view, select the group to which you want to add a virtual address. Next, on the Resources menu, select Add to Group to open the Add Resource to Group Wizard.

Specifying the Resource Type and Group


4.2 Specifying the Resource Type and GroupOn the first page of the wizard, select the Virtual Address resource type, the FSTutorial group, and then click Next.

Describing the Network


4.3 Describing the NetworkWhen you add a virtual address to a group, you need to define the network on which the virtual address runs. If you do not know which addresses are available as virtual addresses on your cluster, ask your cluster administrator.

Enter the data on the wizard page as follows:

1. In the Network section of the page, select "Show networks accessible by clients," and in the Network box, select Public.

2. In the Virtual Address section of the page, enter the host name for the virtual address that you want to create in the Host Name box (your value will be different than the one shown in the image), and then press the Tab key.

When you press the Tab key, Oracle Fail Safe resolves the host name to an IP address.

Your values for the virtual address will be different from the ones shown in the image. Also, do not use the cluster alias; in this example, the cluster alias is ntclu-150.

3. Click Finish.

Finishing Adding the Virtual Address


4.4 Finishing Adding the Virtual AddressOracle Fail Safe asks you to check the properties you have selected for the virtual address. If they are correct, click OK. Otherwise, click Cancel and then Back to change the properties.

After you add at least one virtual address to the group, you are ready to add a resource to the group (such as an Oracle single-instance database, Oracle Forms Server, Oracle Reports Server, Web server, or other resource).

Viewing the Group Properties


4.5 Viewing the Group PropertiesFrequently, you will need the virtual address or addresses of a group when you are adding resources to the group. These addresses are displayed in the wizard you use to add a resource to a group. You can also see a list of these addresses in the Virtual Addresses property page. This property page shows the virtual address that you just added to the group.

Creating a Sample Single-Instance Database 5-1

5Creating a Sample Single-Instance

Database

This lesson shows you how to create a sample single-instance database called SAMPLEDB. The rest of this tutorial assumes you have created this database.

Opening the Create Sample Database Dialog Box


5.1 Opening the Create Sample Database Dialog BoxIn the tree view, select the cluster (or an object on the cluster) on which you want to create the sample database. Then, on the Resources menu, select Create Sample Database to open the Create Sample Database dialog box.

Using the Create Sample Database Dialog Box


5.2 Using the Create Sample Database Dialog BoxEnter a service name of SAMPLEDB, select a disk and node combination on which to build the sample database, and then select the version of the Oracle database that you want to create and the Oracle home in which to create it. For the disk resource, Oracle Corporation recommends you select a disk other than that which is used for the quorum resource. (To view the disk used for the quorum resource, select the cluster alias in the tree view, then click the Quorum tab.) Click OK.

The sample database always uses the SYS account with a password of change_on_install. Do not use the sample database as a production database.

Starting the Default Oracle Intelligent Agent


5.3 Starting the Default Oracle Intelligent AgentOracle Fail Safe opens a Creating Sample Database window to display the progress of the operation. This may take a few minutes. During the operation, Oracle Fail Safe opens a Clusterwide Operation Query window to ask if you want to restart the default Oracle Intelligent Agent. Click Yes.

Viewing the Progress of the Clusterwide Operation


5.4 Viewing the Progress of the Clusterwide OperationWhen the operation completes, Oracle Fail Safe opens a Clusterwide Operation Status window to let you know whether the operation has completed successfully.

Click OK.



Verifying a Standalone Single-Instance Database 6-1

6Verifying a Standalone Single-Instance

Database

If you add a standalone database (that you did not create using Create Sample Database) to a group, you should verify the database before adding it to a group. When you verify a standalone database, Oracle Fail Safe uses data that you supply to attempt to fix any problems it finds clusterwide.

Because Oracle Fail Safe created it, you do not need to verify the database that you created in Chapter 5. However, for the purpose of demonstration, you will do so in this lesson.

Using the Verify Standalone Database Command


6.1 Using the Verify Standalone Database CommandIn the tree view, select the SAMPLEDB.us.oracle.com database. Then, in the Troubleshooting menu, select Verify Standalone Database.

Using the Verify Standalone Database Dialog Box

Verifying a Standalone Single-Instance Database 6-3

6.2 Using the Verify Standalone Database Dialog BoxThe contents of the database information fields are retrieved automatically. If a value is too long for a field, you may not see the entire value.

In the Account box, select the "Use operating system authentication" option. (If a window opens with a question similar to the following, click Yes: "To use operating system authentication, the user, domain\administrator must be added to the dba group ORA_OFS1_DBA. Should Oracle Fail Safe add this user for you?")



6.3 Viewing the Progress of the Clusterwide OperationOracle Fail Safe displays the results of the Verify Standalone Database operation. (During the operation, a message window may ask if you want to start the SAMPLEDB instance. If this message is displayed, click Yes.)

Adding a Single-Instance Database to a Group 7-1

7Adding a Single-Instance Database to a

Group

This lesson shows how to add a single-instance database to a group. When you add a single-instance database to a group, you make that database highly available. If the node on which the database is currently running is taken offline or fails, the database is restarted on a surviving cluster node.

In this lesson, you will add the sample database that you created in Chapter 5 to the FSTutorial group that you created in Chapter 3.

Invoking the Add Resource to Group Wizard


7.1 Invoking the Add Resource to Group WizardIn the tree view, select the SAMPLEDB.us.oracle.com database, then on the Resources menu, select Add to Group.

Using the Add Resource to Group Wizard


7.2 Using the Add Resource to Group WizardThe Add Resource to Group Wizard steps you through the process of adding the database to the group. On this page, select Oracle Database (if it is not already selected) and then select the FSTutorial group from the Group Name pull-down menu.

Click Next.

Specifying the Database Identity


7.3 Specifying the Database IdentityTypically, the Service Name, Instance Name, Database Name, and Parameter File fields are retrieved automatically. However, if the parameter file disk is not on the same node as the database instance, then the database name will not be prefilled. If this is the case, enter the database name in the Database Name field.

Click Next.

Selecting a Database Authentication Method


7.4 Selecting a Database Authentication MethodOracle Services for MSCS must have access to the database. Oracle Services for MSCS accesses the database from two accounts, the account running the Oracle Services for MSCS service and the account running the Cluster Server service. The account running the Oracle Services for MSCS service accesses the database during configuration and verification operations; the account running the Cluster Server service accesses the database when monitoring database status and when placing the database online or taking it offline.

You can choose for the services to access the database using the account or accounts under which they are running (which is called operating system authentication) or to access the database using the SYS account.

Select the "Use operating system authentication" option.

Note: This page will not be presented if the account (or accounts) under which the services are running is already a member of either the ORA_DBA or ORA_<SID>_DBA Windows operating system group.

Adding the Account to the Windows ORA_<SID>_DBA Group


7.5 Adding the Account to the Windows ORA_<SID>_DBA Group When you select the "Use operating system authentication" option, Oracle Fail Safe opens a window to confirm that you want to add the account or accounts under which the Oracle Server for MSCS and Cluster Server services are running to the ORA_<SID>_DBA group. Click Yes. Then click Next in the Database Authentication Wizard page.

In this example, Oracle Services for MSCS and MSCS are both running under the nedcdomain\cluadmin account and OFS1 is the SID of the SAMPLEDB database. If they were running under different accounts, both would be added to the ORA_OFS1_DBA group. (The values presented to you when you follow this tutorial may be different.)

Specifying a Password File


7.6 Specifying a Password FileOn this page, you can choose whether or not Oracle Services for MSCS will create a password file for the database on each cluster node. If you choose not to have Oracle Services for MSCS create a password file on each cluster node, then database administrators who want to access the database must be members of the ORA_DBA or ORA_<SID>_DBA Windows operating system group and will only be able to perform database administration tasks from the node on which the database resides; applications such as Recovery Manager will not be able to access the database from a noncluster node.

This lesson specifies that Oracle Services for MSCS will create a password file. Select the "Yes, create the password file" option, and enter and confirm the password for the SYS account. The default password for the SYS account is change_on_install.

Finishing Adding the Database


7.7 Finishing Adding the DatabaseOracle Fail Safe asks you to check the properties you have selected for the database. If they are correct, click OK. Otherwise, click Cancel and then click Back to change the properties.

Shutting Down the Database


7.8 Shutting Down the DatabaseIf the database is running, Oracle Fail Safe displays a window to warn you that it must shut down the database. Click Yes to shut down the database and continue the process.



7.9 Viewing the Progress of the Clusterwide OperationOracle Fail Safe displays the progress of the Add Database to Group operation.

Verifying a Group 8-1

8Verifying a Group

A group verification checks that the selected group is configured correctly. Over time, as your system becomes more complex and hardware and software configurations change, you may find that resource dependencies have changed. The Verify Group command makes it easy to restore the configuration to working order. When you use a Verify Group command, Oracle Fail Safe attempts to correct any configuration problems it finds. It is not necessary to verify a group immediately after you create it, but it is done in this lesson to demonstrate the operation.

Using the Verify Group Command


8.1 Using the Verify Group CommandIn the tree view, right-click the FsTutorial group name, then select Verify Group.

Viewing Progress

Verifying a Group 8-3

8.2 Viewing ProgressBecause the Verify group operation is applied clusterwide and involves numerous steps, it can take a few minutes to complete. Oracle Fail Safe Manager displays the progress of the operation to you.

When the operation is complete, click OK in the Cluster Operation Status window and Close in the Verifying Group FsTutorial window.

Balancing the Workload 9-1

9Balancing the Workload

Oracle Fail Safe Manager makes it easy to balance the workload across the nodes in the cluster using a process called planned failover. You can use planned failover to adjust the initial setup of the cluster, or to adjust the setup if the cluster environment changes.

Initial Set Up for Performing a Planned Failover


9.1 Initial Set Up for Performing a Planned FailoverCreate three groups: Sales, Marketing, and Customers. Create Sales and Marketing on one node (NTCLU-151 is used in this example); create Customers on the other node (NTCLU-152 is used in this example).

Enable failback for each group, and set the current node of each group at the top of the Preferred Owner Nodes list. See Chapter 3 for instructions on creating a group. For the purposes of this example, you do not need to add virtual addresses to the new groups.

The following figure shows the initial configuration of the cluster:

Suppose that you have recently added more CPUs to NTCLU-152. Node NTCLU-152 can better handle the load of the Sales and Marketing groups, and NTCLU-151 would now be a better place for the Customers group. You can move the groups to the new, more capable system with minimal interruption in service to your users.

Moving the Sales Group


9.2 Moving the Sales GroupBecause NTCLU-152 is the more robust system, the first step is to move Sales and Marketing groups to NTCLU-152.

To move the Sales group from NTCLU-151 to NTCLU-152, right-click on the Sales group and select Move to a Different Node. (Your node names will be different.)

Confirming the Move Group Operation


9.3 Confirming the Move Group OperationA confirmation window asks if you want to move the Sales group to NTCLU-152. Click Yes.

Finishing Moving the Group


9.4 Finishing Moving the GroupThe Moving Group window displays the progress of the move operation. When the move is finished, click Yes in the Clusterwide Operation Status window, then click Close in the Moving Group window.

Moving the Marketing Group


9.5 Moving the Marketing GroupTo move the Marketing group from NTCLU-151 to NTCLU-152, right-click on the Marketing group and select Move to a Different Node.

Complete the move operation as described in Section 9.3 and Section 9.4.

Moving the Customers Group


9.6 Moving the Customers GroupTo move the Customers group from NTCLU-152 to NTCLU-151, right-click on the Customers group and select Move to a Different Node.

Complete the move operation as described in Section 9.3 and Section 9.4.

Checking the Preferred Owner Nodes List


9.7 Checking the Preferred Owner Nodes ListCheck the Preferred Owner Nodes list. Select the Sales group from the tree view and click the Nodes tab. The data on this page indicates that NTCLU-151 is the preferred owner node. However, now that you have rearranged the configuration, you probably want NTCLU-152 to be the preferred owner node. With the current settings, if NTCLU-152 fails and the Sales group fails over to NTCLU-151, the Preferred Nodes list indicates that you prefer the Sales group to reside on NTCLU-151; failback will not occur when NTCLU-152 comes online.

Rearranging the Preferred Nodes List


9.8 Rearranging the Preferred Nodes ListRearrange the Preferred Nodes list so that NTCLU-152 is first in the list and NTCLU-151 is second. Select NTCLU-152 from the Available Nodes list and click the right-arrow button, then select NTCLU-152 from the Preferred Nodes list and click the up-arrow button. The Preferred Nodes list should list NTCLU-152 first and NTCLU-151 second.

Repeat this process for Customers and Marketing, ensuring that the node on which you want each group to reside when both cluster nodes are up is first in their respective Preferred Nodes list.

Viewing the Balanced Workload


9.9 Viewing the Balanced WorkloadWhen you finish the planned failover, the Oracle Fail Safe Manager tree view should appear similar to the following image when you expand both of the Nodes folders for NTCLU-150 and the Groups folder below each Nodes folder in the tree view, then click any one of the Groups folders.

Identifying the Location of Fail-Safe Databases to Client Applications 10-1

10Identifying the Location of Fail-Safe

Databases to Client Applications

Ordinarily, end-user applications identify the location of a database by its physical node address. When you add a database to a group, the location of the database in the group is identified by the virtual address of the group.

Updating the tnsnames.ora File


10.1 Updating the tnsnames.ora FileIf your end-user applications use tnsnames.ora to locate databases, use a tool such as Oracle Net Assistant to change the host value in tnsnames.ora on client systems from the physical node address to the virtual address of the group. Oracle Fail Safe makes this update for you on the server systems and the client system from which you are running Oracle Fail Safe Manager.

Creating and Adding a Forms Server and an Oracle HTTP Server to a Group 11-1

11Creating and Adding a Forms Server and an

Oracle HTTP Server to a Group

This lesson demonstrates how to make an Oracle Forms application deployed on the Web highly available. This is done by making both the Oracle Forms Server and the Oracle HTTP Server highly available.

Oracle Fail Safe can add an existing Forms Server to a group, or it can create and add a Forms Server to a group; both are done using the Add Resource to Group Wizard. This lesson will first create and add a Forms Server to a group, then create and add an Oracle HTTP Server to the same group so that the form can be viewed on the Web.

Because this lesson requires preparation, you might find it helpful to print this introduction before continuing.

Use the following table to record data that is specific to your configuration. The first column lists the items needed for this lesson. The second column lists the values used in this tutorial. In the third column, enter the values that correspond to your configuration.

Item Tutorial Value Your Value

Virtual address of Forms_Group: IP address 138.2.26.156

Virtual address of Forms_Group: Node name NTCLU-156

Before running this lesson, perform the following operations:

1. Make sure the system software requirements have been met, as described in Chapter 1.

2. Create a group called Forms_Group and add a virtual address to it, as described in Chapter 3 and Chapter 4.

3. If you have not already done so, install the demo database objects that ship with Oracle Fail Safe, using the database that you created in Chapter 5, by performing the following operation:

a. Connect to your database as system/manager.

b. Run <Oracle_Home>\fs\fssvr\demos60.sql using a tool such as SQL Worksheet.

4. Create a \Forms directory on a cluster disk that you have designated for the Forms Server.

5. Create an \HTTPServer directory on a cluster disk. In this directory, create an \htdocs directory.

6. Copy calcform.fmx from <Oracle_Home>\fs\fssvr on one of the cluster nodes to the \Forms directory.

7. Copy WebForm.htm from <Oracle_Home>\fs\fssvr on one of the cluster nodes to the \HTTPServer\htdocs directory. This will be the default page for the Web server.

Removing a Resource from a Group 13-1

13Removing a Resource from a Group

When you are done experimenting with a resource, you probably want to delete it from the cluster. Before you can delete it from the cluster, you must first remove it from the group to which you added it. Note that you can only use the Remove from Group command to remove those resources from a group that you added with the Add Resource to Group Wizard.

Using the Remove from Group Command


13.1 Using the Remove from Group CommandIn the tree view, select Forms_Tutorial. Then, on the Resources menu, select Remove from Group.

Confirmation Request

Removing a Resource from a Group 13-3

13.2 Confirmation RequestWhen you remove the Forms_Tutorial from the group, Oracle Fail Safe asks, "Are you sure you want to remove the resource Forms_Tutorial from the group?" Click Yes.

(Note that when you remove a database from a group, Oracle Fail Safe warns you that the database will be shut down and all users will be disconnected.)



13.3 Monitoring the Clusterwide OperationOracle Fail Safe opens a window and begins the remove operation. The upper portion of the window displays the status of individual resources in the group, and the lower portion of the window displays the progress of the remove operation.

Because the Forms_Tutorial and the Forms_Site use the same cluster disk, Oracle Fail Safe reports a warning to indicate that the cluster disk used by the Forms_Tutorial cannot be removed from the group because it is also used by the Forms_Site. This is expected. Click OK in the Clusterwide Operation Status window, then click Close in the Removing Resource window.

Deleting a Standalone Resource from the Cluster 14-1
