Modifying Topologies

You can change one of the installed topologies by adding components to it. For example, you might want to install more J2EESSOInstaller components to a J2EE & Web Cache Topology, or you might want to add a BIInstaller to a J2EE & Web Cache with Identity Management Topology.

To Add Components to an Imported Topology

Upon completion of this task, the selected component is installed in the host that you selected. The selected component is associated with an MRInstaller component. This new component will be uninstalled automatically when you uninstall the MRInstaller component with which the selected component is associated.

Steps

1. In the Application Deployment section of the N1 Grid SPS browser interface, click Components.

2. If needed, select Change Folder and go to /com/sun/oracle10g_AS.

3. From the Components page, select the component that you want to add to a topology.

4. Under component procedures, run the default install.

5. Select the physical host on which you want to install the component.

6. Provide the name of the physical host that has the MRInstaller component.

7. Provide the ORACLE_HOME_NAME value for the host that has the MRInstaller component.

8. Click Run Plan (includes preflight).

To Start an Enterprise-Related Topology

If your system goes down unexpectedly, or if some other event causes your J2EE & Web Cache or J2EE & Web Cache with Identity Management topology to stop, you can start those topologies through the plug-in.

When you start the J2EE & Web Cache or J2EE & Web Cache with Identity Management topology, the top-level component checks the status of any dependent sub-components. If the sub-component is not started, the start control starts the sub-component.

For the Business Intelligence and Forms topology and the Portal and Wireless topology, you have to start the individual components separately. Specifically, you have to start the BIInstaller or PWInstaller component, as well as the applicable J2EESSOInstaller and J2EESSONWCInstaller components.

Steps

1. In the Application Deployment section of the N1 Grid SPS browser interface, click Components.

2. If needed, select Change Folder and go to /com/sun/oracle10g_AS.

3. From the Components page, click the J2EESSOInstaller or J2EESSONWCInstaller component that you want to start.

4. Under component procedures, run the Start control.

5. Select the physical host on which you want to start the component.

6. Click Run Plan (includes preflight).
