GeoServer 3 Oracle OCI TNS problem

Hi,

I now successfully updated the server I’m using for seeding from GeoServer 2.28/Tomcat 9 to last week’s GeoServer 3 nightly build/Tomcat 11. Seeding the tile caches from Oracle and WMS sources works fine like before. The only problem I had is that the oracle.net.tns_names system property is now ignored and sqlnet.ora and tnsnames.ora from the ORACLE_HOME path are used. As those not necessarily reflect the settings I’m requiring, I am looking for a solution to this.

Does anyone have an idea?

Regards
Daniel
