According to fix RO65891, an extra Field Descriptor Table (FDT) entry for USERID was added to the FDTby fix RO63740.
We do have RO63740 applied and verified that there are two entries for USERID with the second entry being the most recent entry added to the FDT.
The instructions in the fix are to:
SMP APPLY, LLA REFRESH and a restart of TSS with REINIT
THEN Execute TSS command: TSS REMOVE(FDT) FDTNAME(USERID)
AND Restart TSS with a REINIT
Does RO65891 have to be applied first, before issuing the REMOVE command or can this be done ahead of time?
RO65891 needs to be applied first before issuing the TSS REMOVE.
The reason is that the fix itself is designed to 'allow' for the remove to work on FDT entry USERID, and not before.
Note: Having the APAR applied will not hurt your system at all. It does nothing until a remove for FDT of USERID is performed. That's all.
