FW: Slow Informix backups every 8 days?
Anyone else care to pitch in an Informix opinion? It would much appreciated. It is obvious to me that TSM is not the booger here, but somehow it keeps ending up in my court. Too bad it's not Night Court, I'd send in Bull Shannon... -Original Message- From: Richard Sims [mailto:[EMAIL PROTECTED] Sent: Friday, April 21, 2006 6:44 PM To: Bell, Charles (Chip) Subject: Re: Slow Informix backups every 8 days?

This is making me suspect that the Informix side of the middleware involved in the backup is blocked by Informix, possibly due to a held lock in the Informix database or the like. You may want to use some combination of lsof and truss commands to see what's going on there. I'm disappointed that no Informix customers have chimed in, as they have expertise in that area, where I've had no experience.

Re: Slow Informix backups every 8 days?
It happened again this morning, but this time one day earlier. No shortcoming from the TSM server side. Why do I get all of the goofy stuff? :^) -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Richard Sims Sent: Tuesday, April 18, 2006 11:34 AM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] Slow Informix backups every 8 days? Chip - This is a case where the server records need to be examined. Look in the TSM server Activity Log for what's happening during that period, and review the TSM accounting records for the recorded wait time values. If need be, perform Query SEssion during the backups to see what clients may be waiting on (drives, volumes, etc.). Just looking at the client side of things gives you only half the story.

Slow Informix backups every 8 days?
Client OS AIX 4.3.3 Informix Dynamic Server Version 7.31.UD4 TDP for Informix v4.1.3 TSM v5.1.5 Why would the client back up in a way that is considered normal (45 mins. to 1 hr), but every 8th day take well over 3 hrs? Has anyone seen this happen every 'x'th day at their site? God bless you!!!
