Uninstall/reinstall Application Server

When you uninstall Application Server, the services database is not deleted from the system. This means that any existing galaxy pairings will persist when you reinstall Application Server on the same system. The persistent pairing information is automatically available after the reinstallation.

This pairing information, however, can be out of date and multi-galaxy operations not working as the Discovery Service information is lost in the transition from uninstall to install.

To resolve out-of-date pairing information, you must unpair and re-pair to the required galaxies after performing uninstall and re-install operations on the same node.

For example:

1. Install the latest Application Server software on two nodes, Node1 and Node2.

2. Create a galaxy with a platform, and pair the nodes.

3. On Node1, uninstall Application Server and restart the system.

4. On Node1, reinstall Application Server and connect to the same galaxy.

5. Open the Multi-Galaxy Configuration dialog. Notice that all the pairing information has persisted through the uninstall-reinstall operation. Also, notice that multi-galaxy operations are not functioning. You can’t browse to or subscribe from Node2 even though the nodes appear to be paired.

6. Unpair and pair Node1 to get the new Discovery Service and pairing information from Node2.
