Re: Z900 (2064 - 216) Problem. TO: 1 recipientShow Details Well this is interesting: Excp, Conn are the same!! Apparently there is no difference in the actual I/O. TCB and SIO are higher. What is SIO, where does this come from? What is the relationship between Excp and SIO? Do you use hardware compression, can this be switched off after 12 hours?

Please describe your 'simple dump'. Memory dump? Dump of volsers? Is it dump by application or by DFDSS? >There is no any user on the machine during these test. >The CICS and DB2 were down. During or before degradation? You should really check your EREP again and make sure you get all your records from all LPARS. Oh, yes, check your Coupling Facility (with your IBM CE) if you have any problems. Kees asked you lots of other questions, could you perhaps post your replies here?
