Prior to enabling an OpenEdge database for use in a cluster, OpenEdge must be installed with the Enterprise RDBMS license on every node in the cluster; and the installation path must be identical on every node. When upgrading from earlier releases, all cluster-enabled databases must be disabled before being updated and re-enabled afterwards.
You must also ensure there are no active instances of the Cluster Administrator utility prior to installation. To do this in Windows, use the Windows Task Manager to check for processes running the cluadmin.exe image. If a user associated with an instance of the Cluster Administrator is not readily identifiable, these processes can be forcefully terminated as follows:
Failure to shut down all instances of the Cluster Administrator tool results in a partial installation and fails to properly register the resource and administrator extension DLLs, causing cluster management to fail.
To terminate instances of the Cluster Administrator utility:
1. Within Task Manager, select the cluadmin.exe process and press the End Process button.
2. Answer yes to the popup dialog asking if you really want to terminate the process.
