And then the second delete will fail. And since :>you're seeing a delete fail... What I ended up doing was generating a unique value for each GETSHARED so that I can individually do a DETACH AFFINITY=SYSTEM. Each SHAREMEMOBJ (each in a different address space) uses the exact same token, the block address, with no problem. I wanted to use the same value for each GETSHARED so that they can be easily DETACHed in an ESTAEX/RESMGR, but that appears to be unnecessary. -- Binyamin Dissen <[email protected]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
