Re: periodic ADSM/TSM shutdown
Yes when you run a single application on NT you may only have to reboot every 6-12 months. But as soon as you either 1) install multiple apps on a single NT server, or 2) perform some serious data processing on NT (like 80% CPU utilization 20 hours a day) then reboots become much more frequent. -- Joshua S.

Re: periodic ADSM/TSM shutdown
Becky-- you said BMC-- are you running SQL BackTrack? If so, there is a known memory leak problem with all the OBSI modules prior to 2.4.10.2. SQL-BackTrack? OBSI Module for ADSM Technical Bulletin Version 2.4.10 August 16, 2000 *100033286* Problem BMC Software is alerting users of SQL-BackTrack OBSI Module for ADSM, all versions on all platforms, to a problem. This technical bulletin describes a patch for SQL-BackTrack OBSI Module for ADSM to prevent the problem from occurring. There is a memory leak in the SQL-BackTrack OBSI Module for ADSM product. For every 64k block of data recovered, there is a loss of 8 bytes. Depending on the minimum bytes allocated by your memory management system, this could result in a greater loss for each 64k block of data being recovered. Solution To fix this problem, download the patch from the BMC ftp site using the following instructions: Connect to the ftp site: ftp ftp.bmc.com |+---> || Tim Melly| || | || | || 10/13/2000 | || 07:11 AM | || Please | || respond to | || "ADSM: Dist | || Stor Manager"| || | |+---> >| || | To: [EMAIL PROTECTED] | | cc: (bcc: Lisa Cabanas/SC/MODOT) | | Subject: Re: periodic ADSM/TSM shutdown | >| Pat, I'm running 3.1.2.40 on AIX 4.3.2 (yes, were upgrading shortly) and I've encountered a similar problem.

Re: periodic ADSM/TSM shutdown
We had several occurances over many months that required bouncing the server because a non-existant transaction had a high numbered log page locked. This occurred after a problem with our ACSLS systems or a tape drive; but not after every problem. You have the problem when the percent utilization of the log file doesn't reduce to near zero after a database backup. Since moving to 3.7.1 we have not had the problem.

That's what we've been discussing. There is no need to recycle the TSM server on a regular basis. If you have a TSM server problem, get it fixed - don't simply live with it. If you have problems with a level of the server or client when a later maintenance level is available, go to that level.

Re: periodic ADSM/TSM shutdown
This may be theoretically true, but things do crop up. At 3.7.2, I had problems with defunct processes, growing until around 1000 or so, the system had slowed down to the point I needed to restart. This stopped at 3.7.3.8 (the next level I put on). I believe the below statement generally, but you have to keep an open mind. Bad things creep in once in a while.

Becky - So you are saying that there are people at BMC who are being paid large sums to render misadvice to companies depending upon them for authoritative information? Oh, the slippery eels in this industry. As you can tell from prior responses, you haven't seen any recommendations because there is no reason to cycle the server. All of us have our servers running indefinitely, performing without incident (barring product defects which may themselves cause outages). So, no, there is no need to cycle the server on a regular basis. On the other hand, there is some cause to cycle your advisors... Richard Sims, BU
