Hi David, We had a similar problem that was caused by the enhanced validation added in later EAPs, mentioned here https://access.redhat.com/solutions/4010511 I can't remember the exact solution but I think we had a class wrongly specified in our xml and we had to correct it per the documentation https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_ap....

One suggestion was to use the CLI to add the driver. Tried that and no change. Is there a way to increase logging beyond DEBUG? Or is there somewhere it logs more information other than the server.log file? It says failed to load but doesn't give details as to why.

I'm running into a problem getting it to load the oracle driver and I assume I'm missing a step but I have followed the guide here: https://www.keycloak.org/docs/latest/upgrading/index.html I have: unpacked 6.0.1 mv standalone directory to standalone.old cp -R 3.2.1/standalone to 6.0.1/ cp -R 3.2.1/modules/system/layers/keycloak/org/oracle 6.0.1/modules/system/layers/keycloak/org/ cp -R 3.2.1/themes/<our-themes> 6.0.1/themes/ 6.0.1/bin/jboss-cli.sh -file=bin/migrate-standalone.cli (feedback indicates success on all actions) Made sure migrationStrategy value="update" When I run 6.0.1/bin/standalone.sh I get: ... 09:26:10,588 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 31) WFLYCTL0013: Operation ("add") failed - address: ([ ("subsystem" => "datasources"), ("jdbc-driver" => "oracle") ]) - failure description: "WFLYJCA0114: Failed to load datasource class: oracle.jdbc.driver.OracleDriver" Again, this works in my 3.2.1 on the same server, so I assume my datasource and driver declaration are correct in standalone.xml file as well as the module.xml and ojdbc8.jar. I also can confirm the datastore is in use for the 3.2.1 install through connecting to the DB store using TOAD for oracle. I have confirmed permissions on the entire Keycloak directory structure are identicle between the 3.2.1 and 6.0.1 locations. Is there another step or declaration of the driver or something that I must do? Thank you for your time, Dave

Hello David, The 4.6.0 release featured the upgrade to Wildfly 14, I believe that could be the cause. Just did the following (Keycloak 4.8.3): - added Oracle driver via jboss-cli: module add --name=oracle --resources=/path/to/oracle.com/ojdbc8.jar --dependencies=javax.api,javax.transaction.api - went to Wildfly console (localhost:9990) and added a datasource via the UI. This worked perfectly, and resulted in the following subsystem config (see attachment). I suggest that you check how that is different from what you have currently.
