Problem: While trying to add Oracle monitor in linux machine it fails with following error message.
ORA-00604: error occurred at recursive SQL level 1
ORA-01882: timezone region not found
Cause: This is due to jar incompatibility while adding Oracle Database monitor of version 10g or lower in Applications Manager.
Fix: Unzip working/classes/classes12.zip file.
Open /oracle/jdbc/defaultConnectionProperties.properties file. Inside the file copy and paste the below mentioned content.
oracle.jdbc.timezoneAsRegion=false.
Zip the file again with same name (classes12.zip), replace it and restart Applications Manager.
