FlashCopy Manager (FCM) as delivered uses TLS 1.1 and lower protocols for SSL sessions. The GSKit component of FCM is only vulnerable to this security issue if SSL sessions use TLS 1.2 (or higher) protocol.
No action is required if the profile parameter ENFORCE_TLS12 is not present (this is the default) or is set to NO in the FCM profile.
If the ENFORCE_TLS12 parameter is set to YES, then it should be changed to NO to eliminate exposure to this security issue and the processes should be restarted by running the following commands:
setup_<application>.sh -a stop
setup_<application>.sh -a start
The script “setup_<application>.sh” is located in the FCM instance directory. The value of <application> depends on the Database/Application type being protected and is “db2” for a DB2 database, “ora” for Oracle with and without SAP, or “gen” for custom applications.
