The ASID is made non-reusable because the address space that owned it last owned a space switch LX (system or not is irrelevant) -or- a more complicated situation exists where there are secondary dependencies. IAC the LX can be reused and the ASID not be. " The fact that an LX was published by an AS, implies that the AS has a chance to be connected to at any time in the future. This cannot be avoided/eliminated by shutting down XM asids. Possible only when the LX is reused by another AS, this AS is freed from unintended XM connections and might be reusable again.

Re: RSVNONR again
Radoslaw, This is a great ASM program that was published in MVS update: http://www.xephon.com/cgi-bin/xephon3/licence/getcode.cgi?pubfile=November.2001&datafile=M182A08 However, It only works up to OS/390 2.10. To get it to work under z/OS you should modify it to use the correct offsets in the XMSE as described in the APAR Rob Scott pointed to. Gil.

Re: RSVNONR again
MXI (www.rs.com/portfolio/mxi/) has the following two commands : MDQ - The Memory Delete Queue - those ASIDs that have been marked non-reus and the reasons why. XM - Active Cross-Memory Connections - shows the active cross-memory connections between address spaces in the system. Both these commands require MXI to be running authorized at the code involves snooping around control blocks in the PCAUTH address space. SHOWMVS (www.cbttape.org) also has this functionality. -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of R.S.
