There are a certain amount of defined user segments within the Top Secret Field Descriptor Table (FDT). Is there a way to determine which user has such a segment and list any user having a specific segment.
There is not a TSS WHOHAS to list the segments. You have to use TSS LIS(ACIDS) SEGEMENT(segment#) and then scroll down within the entire output to find who has it. (For exampole, F segment# when browsing the output file.)
You could run the TSS LIS(ACIDS) SEGEMENT(segment#) command during off peak hours, in batch, since this command is I/O intensive. Then search or have an EARL or REXX to parse the output to find who has the segment# segment.
