z/OS does not do anything to the Access List Entry. It is up to the program that added it to delete it when it wants to.
A reference after address space A terminates will initially result in an ASTE-validity exception (Program check code x'2B', 0E0-2B ABEND). If the ASID gets reused, then it will result in an ASTE-sequence exception (Program check code X'2C', 0E0-2C ABEND). Yes, after ALESERV DELETE, the Access-List-Entry Number is available for reuse with a new ALESN.

Address space X task Y adds an ALET for A/S A to its DUAL (or the PASN).(Yes, in general a bad practice). Address space A goes down. Does the system EOM take care of invalidating ALETs that refer to it? Or does zOS wait for a reference which will fail the ASTESN match and then the ALEN-invalid bit is set? Or it just keeps failing on ASTESN/ Finally, when an ALESERV DELETE is issued, is the ALET number available for reuse by zOS with a new ALESN? Or is it lost? -- Binyamin Dissen <[email protected]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
