TSSCFILE records 9623 and 9629 not documented in the Top Secret manuals online.
Release :
Component : CA Top Secret for z/OS
TSSCFILE record types:
9629 = Expanded change-counter enhancement indicator. I am not sure this enhancement for setting this setting was ever implemented. There are indications it was being held off for a release boundary.
9623 = SDNSIZE shows the current setting for SDN (Subject Distinguished Name) size implemented as an enhancement via PTF RO17782. I will get a definitive answer on these two and update the case.
Documentation will be added in a future update to the Top Secret online manuals.
