Activating a feature on a multiple primary servers configuration

  1. Stop the lead primary server.
    The alternate primary server detects that the lead primary server is not available and becomes the active primary server. This transition can take up to two minutes.
  2. Wait for the alternate primary server to become the active primary server.
    Before you continue, verify that the alternate server is functioning as the active primary and that the UI server is connected to it.
  3. On the server that you stopped at step 1, activate a specific feature.
    For example, type:
    /aiw/aiw1/bin/xact -d PDFDocumentSupport-1.0.1740394835.epk
    1. If activation succeeded, proceed to the next step.
    2. If activation fails, verify that the alternate primary server and the UI Server are still working correctly before you retry.
  4. Start the server that you just installed the feature on.
  5. Stop the active primary server.
    The lead primary server becomes the active primary.
  6. Wait for the processing to switch back to the other primary server.
    The server that you installed the feature on must be the active primary server before you synchronize other servers to make sure the updated UI configuration files are built before synchronization.
  7. Synchronize the UI server with the lead primary server:
    1. As root user, on the UI server, type: ~/rpd-sync.sh leadprimary_hostname
    2. Restart the UI server.
  8. Verify that the lead primary server and the UI server are working correctly with the updated feature.
  9. Synchronize the alternate primary server with the lead primary server:
    1. As root user, on the alternate primary server, type: ~/rpd-sync.sh leadprimary_hostname
  10. Start the alternate primary server.
  11. Stop the lead primary server.
    The alternate primary server becomes the active primary.
  12. Verify that the alternate primary server and the UI server are working correctly with the updated feature.
The feature is now activated on both primary servers. Either server can operate as the active primary with the new feature available.
