We need to install the product binaries and the profiles locally instead of on the shared disks for this scenario. You also need to enable high availability for the Transaction Manager and move the transaction log directories onto the shared disk. Figure 11-7 shows our WebSphere setup.
The WebSphere configuration steps are described in great detail in 9.6.3, Configuring WebSphere for TM No Operation policy. This is what do:
| 1. | Follow the steps described for configuring the TM in Enabling high availability for the Transaction Manager. |
| 2. | Copy the transaction logs to the shared file system as described in Copying existing transaction logs to the shared directory. |
| 3. | Inform the Transaction Manager of the new transaction log locations as described in Pointing the TM to the new location for the transaction logs. |
| 4. | Create the HA policy. See Creating the No Operation policy for the Transaction Manager. |
