Post 12c Upgrade : ORA 68 Error


Recently after 12C database upgrade one of  our customer complaints that they are facing ORA-00068: invalid value parameter _query_execution_time_limit error.

 .


When we checked alert log, we noticed following information message


WARNING: Oracle executable binary mismatch detected.
Binary of new process does not match binary which started instance
issue alter system set "_disable_image_check" = true to disable these messages
SOLUTION:

!. Database is working and we want to suppress the messages we can alter the system as below
alter system set "_disable_image_check" = TRUE
2. Bounce database.
