The oracle database I am using as a datasource is unavailable to Geoserver sometimes–If I go to the Demo page to view features I get a servlet error.
The workaround for this is to restart geoserver–then all is well and the features show up again for the oracle datastore.
Here are my ideas for what is happening:
Either the network connectivity is an issue and geoserver does not reconnect its connections to the datastore
Geoserver needs some connection pooling set up?
I have the geoserver war deployed on IBM websphere–I am not running it standalone.
