Environment

Upgrade to 16.0.3 or higher 

Cause

The oracle thin driver seems to accept only 30 characters for the os user property in V$SESSION

Resolution

Workaround 1: 

• Post failure revert back the upgrade 
• Create or use an OS user less than or equal to 30 character
• Set the new user in the CSA and start the upgrade

Workaround 2:

• Set the Environment Variable JAVA_TOOL_OPTIONS using "export JAVA_TOOL_OPTIONS=-Doracle.jdbc.v\$session.osuser=<username>" . Replace username with another user which is not updated as OS user in properties.xml 

Post Upgrade Steps after following Workaround 2: 

• Add  "-Doracle.jdbc.v\$session.osuser=<username>" to the JVM parameters of all the services.
