H06.23 Release Version Update Compendium

Migration Considerations
If the original SSHCFG file is used for SSH2 processes configured for non-maintenance LANs, this
file will be overwritten with the installation of H06.23. A backup should be kept for fallback
purposes.
Fallback Considerations
After a fallback to a pre-H06.22 RVU, $ZSSP0 and $ZSSP1 processes will not start because their
startup parameter definition points to configuration file SSHMCFG, which does not exist in
pre-H06.22 RVUs. The ZSSHGP file in earlier versions RVUs does not contain an ALTER section,
and the process add commands in the ADD section fail because the process definitions already
exist.
To resolve this problem, after a fallback to pre-H06.22 RVUs, issue these commands at a TACL
prompt:
SCF DELETE PROCESS $ZZKRN.#SSH-ZTCP*
RUN ZMODGP $SYSTEM.ZSSH.ZSSHGP
SCF START PROCESS $ZZKRN.#SSH-ZTCP*
