Using overrides in multithreaded jobs

You can use the following overrides in a multithreaded job (with some restrictions, noted below):

• Override with Database File (OVRDBF) command. You can run this command from the initial thread of a multithreaded job. Only the overrides that are scoped to the job or an ILE activation group affect open operations that are performed in a secondary thread.
• Override with Printer File (OVRPRTF) command. You can run this command from the initial thread of a multithreaded job. Only the overrides that are scoped to the job or an ILE activation group affect open operations that are performed in a secondary thread.
• Override with Message File (OVRMSGF) command. You can run this command from the initial thread of a multithreaded job. This command affects only message file references in the initial thread. Message file references that are performed in secondary threads are not affected.
• Delete Override (DLTOVR) command. You can run this command from the initial thread of a multithreaded job.

The other override commands are not permitted, and are ignored, in multithreaded jobs.
