10 Configuring Oracle Application Server Components for High Availability

Oracle Fail Safe Manager provides a wizard to help you configure instances of the following Oracle Application Server components for high availability:

The following topics are discussed in this chapter:

10.1 Prerequisites for High Availability

If a metadata repository is in the same home where you installed Oracle Application Server, then before adding instances of Oracle Application Server components to a group, you must do the following:

You need the following information to complete the wizard. Examples are provided in parentheses.

10.2 Procedure for Configuring Oracle Application Server Components for High Availability

To configure Oracle Application Server components for high availability, perform the following steps:

  1. Install Oracle Application Server as described in Oracle Application Server Installation Guide (10g Release 2 (10.1.2) for Microsoft Windows).

  2. Open Oracle Fail Safe Manager.

  3. On the tree view, select the standalone Oracle Application Server instance that you want to add to a group.

  4. From the Resources menu, select Add to Group. The Add Resource to Group Wizard opens.

  5. In the Resource Type box, select Oracle Application Server.

  6. In the Group Name box, select the group to which you want to add Oracle Application Server.

  7. Click Next.

  8. Complete the remaining wizard pages. If you need assistance, then click Help on the wizard page.

Note the following:

10.3 Removing Oracle Application Server Components from a Group

If you decide you no longer want to have Oracle Application Server components configured for high availability, then remove them from the group that contains them.

Because the OPMN server has a dependency on the Oracle Application Server Control service, you must remove the Oracle Application Server Control service from the group before you remove the OPMN server. In addition, if the metadata repository was added to the group when you configured the other Oracle Application Server components into the group, then it must be removed after the Oracle Application Server Control service and the OPMN server are removed because of dependencies it has on the other components.

To remove Oracle Application Server components from a group:

  1. Open Oracle Fail Safe Manager.

  2. In the tree view, select the Oracle Application Server Control service that you want to remove and then, on the Resources menu, select Remove from Group.

  3. The Confirm Remove Resource from Group box opens. Click Yes in the Confirm Remove from Group box. A window opens to show you the progress of the operation.

  4. When the operation to remove the Oracle Application Server Control service completes, select the OPMN server that you want to remove and then, on the Resources menu, select Remove from Group.

  5. The Confirm Remove Resource from Group box opens. Click Yes in the Confirm Remove from Group box. A window opens to show you the progress of the operation.

  6. When the operation to remove the OPMN server completes, select the metadata repository (if it was added when you configured the Oracle Application Server Control service into the group) and then, on the Resources menu, select Remove from Group.

  7. The Confirm Remove Resource from Group box opens. Click Yes in the Confirm Remove from Group box. A window opens to show you the progress of the operation.

After you remove the Oracle Application Server components from a fail-safe group, they remain on the cluster as standalone resources. Note the following:
