Hello, We are currently running TSM Version 3, Release 7, Level 3.6 on OS/390. We upgraded from version 3.1. On the 3.1 version I used to run a select command to show me how many tapes each node was using. Here is the select command: select node_name, count (distinct volume_name) as Numvols from volumeusage - where stgpool_name='TAPEMCO' group by node_name order by Numvols desc > tapem.txt This select used to take about 45 minutes to run on the 3.1 version but now this select command simply grinds the server to a halt. I eventually have to cancel adsm to recover the server. Is there something about the 3.7 version or my select command that would cause this kind of problem. If the command takes 2 hours to run then that is fine but I can't have the server slowed down so much that I cannot do other things. -- Mark Brown Operations Supervisor ===================== Tel ---> 514-398-2321 Fax ---> 514-398-6876 E-mail ---> [EMAIL PROTECTED]
