Re: Moving /var/mqm/log
Jeff, We've done this on several occasions with no problem. Stop the QMgr(s) and tar up all of /var/mqm/*. Remount/remap drives as necessary and then untar the files back to /var/mqm/*. Voila! If you've mounted /var/mqm/log to a separate filesystem you can use the same basic methodology and just do that filesystem. Important part is that the files map to the same logical path as before. -- T.Rob -Original Message- From: Jeff A Tressler [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 31, 2002 10:37 AM To: [EMAIL PROTECTED] Subject: Moving /var/mqm/log We currently have our MQSeries logs on a disk array.

Re: Moving /var/mqm/log
I don't believe thee is an external pointer to the position in the logs. Internal? Who knows. But if it is internal you may carry it with the logs when you move them. An example for you is when the LOGs are hosed because of some mysterious file problem. Certainly not MQ if you talk to support. But a LOG file error none the less. In this case you must create a new QMGR and replace all the existing logs in the 'active' directory of the de-funked QMGR with the logs of the new QMGR you just created (copy them because without them you cannot delete the new QMGR with the dltmqm command) and restart the de-funked QMGR. This is affectionately known as COLD starting a QMGR. No recovery is performed because there is no information to recover from. Here is a case where LOGs are moved and copied into place. So this may satisfy your question on if you are going to screw up things. bobbee From: Jeff A Tressler <[EMAIL PROTECTED]> Reply-To: MQSeries List <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Moving /var/mqm/log Date: Tue, 31 Dec 2002 10:37:16 -0500 We currently have our MQSeries logs on a disk array.
