Check the archives. This is WAD. DB2 uses cross memory services to operate, and in order to reduce the number of resources it uses, at subsystem initialization, it issues an SRB into the MASTER address space to allocate the system LX's. Because of this, when DB2 subsystems shutdown, the ASN's are marked as non-reusable because there is a XM linkage between ASN 1 and the DB2 ASN's. (I am not sure if the ASN reuse code in z/OS 1.6 changes this, maybe Peter Relson could comment). The best way to avoid this situation is to NOT recycle DB2 regions. I see little reason why DB2 has to be stopped during the lifetime of an IPL.

The -offending- address spaces are -all- DB2 regions that get cycled on a regular basis (I still need to talk to the DBA to see why). We've got Landmark and BMC as well as CICS that -touch- DB2 and we've tryed shutting them down in about everyway possible but the IEF352I message won't go away and of course the used RSVNONR keeps increasing with every shutdown and startup of DB2. It's been 2.5 months since an IPL and we plan on increasing RSVNONR from 99 to 2xx but it just urks me to think we might -have- to have planned IPL's over something this silly. Has anyone found a way around it or do you all just plan an IPL on some scheduled basis and call it a day?
