Deleting an access list entry for a hiperspace z/OS MVS Programming: Extended Addressability Guide SA23-1394-00 |

Access lists have a limited size; the DU-AL has up to 509 entries
and the PASN-AL has up to 510 entries. Therefore, it is a good programming
practice to delete entries from an access list when the entries are
no longer needed. The specific rules are:
Use ALESERV DELETE to delete an entry on an access list. The ALET parameter identifies the specific entry. Programs that share hiperspaces with other programs have another action to take when they delete an entry from an access list. They should notify the other programs that the entry is no longer connecting the ALET to the hiperspace. Otherwise, those programs might continue to use an ALET for the deleted entry. See ALET reuse by the system for more information. |
