If you have just installed the cache in a server or modified an installed cache, refresh the server or the connection cache before you attempt to test the cache. You can refresh as follows:
To refresh the cache:
Highlight the Installed Connection Caches folder under the server icon where the cache is installed.
Select View | Refresh Folder.
To refresh the server, highlight the server icon where the cache is installed, then choose View | Refresh All. All caches installed in the server will be refreshed.
Refreshing a cache may affect running components that are using the cache, specifically:
If you change the connectivity library setting, cache references held by components become invalid. Attempts to retrieve connections or query cache properties will cause errors. In this case, the component must retrieve a new cache handle.
If you change other properties, such as user name, password, server name, or the number of connections in a cache, cache references remain valid, but components may be affected by the changed settings. For example, if you change the server name, connections retrieved after the cache has been refreshed will go to the server indicated by the new name.
