[Geoserver-users] Geoserver 2.8.0 and Oracle - another try

Hi guys

To take the Weblogic and Jetty out of the equation - in my quest for a working Geoserver 2.8.0 - I now tried setting up a test instance of the latest Tomcat 7 with Geoserver, using my existing data directory on Windows x64, using the Windows service installer version of Tomcat. I did this, because as far as I understand, Tomcat is the server you mostly support. I simply had to try something to progress in this. Then I could eventually try convincing my boss of letting me set up a Tomcat server later.

However, this also seems to get me nowhere. I have set the GEOSERVER_DATA_DIR environment variable to the right data directory. I have also set CATALINA_OPTS to

-Xms512M -Xmx1024M -XX:MaxPermSize=128m

according the the “Container considerations”.

Still, the server refuses to start. I again monitor the log closely during boot. The server seems to load all my Oracle data stores as expected. But I never reach a running state. It seems, that regardless of what memory options I specify in CATALINA_OPTS, the server sooner or later blows up with

Also, I get literally TONS of these messages in the log. Then again, this also happens on the production 2.6.2 instance without causing any problems - apparently.

16 okt 15:06:34 ERROR [geotools.jdbc] - There’s code using JDBC based datastore and not disposing them. This may lead to temporary loss of database connections. Please make sure all data access code calls DataStore.dispose() before freeing all references to it

I ask again - what has apparently caused the Oracle driver - which I think is the culprit - to use so much more memory in 2.8 compared to 2.6? I’d like to emphasize once again, that my existing production server runs just fine.

I sincerely hope, that somebody here can provide some hints as to what I can do.

Thanks in advance,

Jacob Madsen

Hum... how many tables are reachable from that user? Did you set a schema?

Just in case...

If you run tomcat as a service, you can not specify Xmx, Xms.... in
startup/catalina.bat. You have to do it in the tomcat service administrator.
