Find the applicable C-CIC SAFELIST record to delete. Note that the C-CIC records are stored using a SYSID value or mask. To see all of the applicable records issue the ACF command (either from ACF mode in TSO, the CP function of the ACFM transaction, or using ACFBATCH):
SET CONTROL(CIC) MSYSID(-)
When you have identified the SAFELIST record to delete, issue:
DELETE SAFELIST.TRANS.recordid SYSID(sysid)
Where "recordid" matches the SAFELIST entry that you want to remove and "sysid" matches the applicable CICS region(s) SYSID where you want to permanently remove this record.
Refer to the CA ACF2 CICS Support section under docops CA ACF2™ for z/OS - 16.0 for additional information regarding the use and maintenance of C-CIC records.
