Implementing and managing APPC protected conversations

Implementing and managing APPC protected conversations

APPC Protected Conversation is a function provided by the operating system to exploiters running on z/OS. This function improves data integrity in distributed processing environments by enabling participation in the two-phase commit protocol. This IBM Redbooks publication provides system programmers...
