After upgrading the Disaster Recovery (DR) Oracle database host server's OS, is there a way to verify that everything is fine post upgrade without enabling DLP services on the DR DLP servers
After upgrading the database OS, run the Update Readiness Tool (URT) on the Enforce server.
The Enforce services do not have to be running to run the URT.
You do need to run the URT on the Enforce server to ensure that the Enforce server can reach the database server.
The URT will use the connection string in the jdbc.properties file to connect to the database.
Again, the Enforce services do not need to be running in order to run the URT.
