How to Deploy the J2EE and Web Cache Topology

Upon completion of this task, each target host has the following components:

• A J2EEInstaller component

• A J2EEHT virtual host that is associated with the J2EEInstaller component

• An Oc4jHolder component that is installed inside the J2EEHT virtual host

• An Oc4jHolderHT virtual host that is associated with the Oc4jHolder component

• An Oc4jInstance component that is installed inside the Oc4jHolderHT virtual host

• An Oc4jInstanceHT virtual host that is associated with the Oc4jInstance component

Steps

1. Create the session variables.

   For this topology, you need to create only the sourceImage and J2EEInstallerPWD session variables.

2. In the Common Tasks section of the N1 Grid SPS browser interface, select Oracle App Server 10g.

3. In the J2EE & Web Cache Topology section of the Oracle App Server 10g Common Tasks page, click Install.

4. On the Plans Details page, click Run.

5. Choose variables to use for the J2EEInstaller component.

   • To use an existing variables set, select a name from the drop-down menu in the J2EEInstaller component row of the Plan Parameters table.

   • To create a new variables set, click Select from List in the J2EEInstaller component row of the Plan Parameters table.

     1. Click Create Set.

     2. Type a name for the variables set.

     3. If a component already exists on this host for which the default value for ORACLE_HOME_NAME is used, define a value for the variable ORACLE_HOME_NAME.

        ---

        Note –

        Two components installed in the same physical host cannot have the same ORACLE_HOME_NAME.

        ---

     4. Save the variables set.

     5. Select the variables set that you just saved from the drop-down menu in the J2EEInstaller component row of the Plan Parameters table.

6. To use a holder name other than the default, choose variables to use for the Oc4jHolder component.

   • To use an existing variables set, select a name from the drop-down menu in the Oc4jHolder component row of the Plan Parameters table.

   • To create a new variables set, click Select from List in the Oc4jHolder component row of the Plan Parameters table.

     1. Click Create Set.

     2. Type a name for the variables set.

     3. Change the Holder Name.

     4. Save the variables set.

     5. Select the variables set that you just saved from the drop-down menu in the Oc4jHolder component row of the Plan Parameters table.

7. To use an instance name other than the default, choose variables to use for the Oc4jInstance component.

   • To use an existing variables set, select a name from the drop-down menu in the Oc4jInstance component row of the Plan Parameters table.

   • To create a new variables set, click Select from List in the Oc4jInstance component row of the Plan Parameters table.

     1. Click Create Set.

     2. Type a name for the variables set.

     3. Change the Instance Name.

     4. Save the variables set.

     5. Select the variables set that you just saved from the drop-down menu in the Oc4jInstance component row of the Plan Parameters table.

8. To select the target host, click Select from List and choose the target host.

   To install the component in several systems at the same time, select more than one target host from the list.

9. Verify that the target host set is not selected.

   The checkbox in front of the target host set should be empty. Otherwise, the plan will try to install in the host set plus the hosts you selected in the previous step

10. Click Run Plan (includes preflight).

    Upon successful completion of the plan, all instances will be running.
