Make TCP/IP stack affinity configurable for RACF subsystem Merged

RACF stack affinity needs to be configurable for systems running with more than one TCP/IP stack. As of now, stack selection is indirectly influenced by access to EZB.STACKACCESS profiles in CLASS(SERVAUTH) and the order in which the stacks became active on the system. This leads to the following:

  1. Invalid access attempts to stacks where no permit has been given to the RACF subsystem user. The more TCP remote nodes and stacks defined the more ICH408I messages are being written to syslog on every connection attempt, especially at subsystem start time (up to 100 in our installation).

  2. Unsuccessful connection attempts with remote nodes getting stuck in "operative pending connection" state when access is granted to stacks other than the desired one and on which the destination IPs are not routable.

RACF itself should not be the component flooding the syslog with ICH408I messages when it's avoidable.
