For LU 6.2, conversation-level security occurs when TRS passes client login information to the mainframe in the conversation-level security fields of the Function Management Header (FMH)-5 along with the client’s request. The mainframe uses this login information to determine whether the client has permission to use the requested resources. For TCP/IP, TRS sends the user ID and password to the Sybase Listener Transaction when the transaction starts.
When configuring RPCs and TRS security, you need to make decisions about:
When to pass login information to the mainframe
What login information to pass to the mainframe
