Re: DB2 on VM question
Tony, I am afraid I don't have any experience with QMF. But there are some pretty sharp folks on this list who probably do. One other thought is even though this is VM DB2, you might want to post to the VSE list as well. There are a couple of folks there who know DB2 and don't follow this list. Good luck!

Re: DB2 on VM
Thanks Roland. I am aware of the VMDSS issues with 5.3 and have those APARs applied. Thanks again. Aria.
Re: DB2 on VM
Hi Aris, that is OK, DB2/VM V7.10 runs well in z/VM 5.30. However, 1) if you are using TCP/IP, make sure that you re-gen the CEEPIPI as documented in Appendix E. IBM Language Environment for VM User Exit Customization for use with TCP/IP in the PD. 2) if you have VMDSS enabled, make sure you have intalled all VMDSS related APARs. a) DB2/VM: - PQ54781 DBSS - SHOW TARGETWS SHOWS WRONG VALUE OF CURRENT WORKING STORAGE WHEN Z/VM IS RUNNING IN 64-BIT MODE. - PQ58880 VMDSS - DURING ROLLBACK, AN 0C8 ABEND IN ARIYT17 COULD OCCUR IF A 2G DATASPACE IS BEING USED. b) z/VM - you have to call z/VM support Good luck. ...Roland - Original Message From: Aria Bamdad <[EMAIL PROTECTED]> To: IBMVM@LISTSERV.UARK.EDU Sent: Tuesday, August 26, 2008 11:43:18 AM Subject: DB2 on VM Hi List, Anyone using an older version of DB2 for VM on a later version (5) of VM?
