Specifying OTMA security

You can make most security specifications for OTMA and OTMA clients by using the transaction message prefixes, the /SECURE OTMA command, and during system definition.

Not every method of specifying OTMA security has the same scope of affect. Some methods allow you to specify security for all members of the OTMA z/OS® cross-system coupling facility (XCF) group, and other methods allow you to specify security for only an OTMA client or an OTMA transaction or command message.
