Cache Hit Percent below 90%
1999-07-29 09:21:37
Hello all,
I've run into a problem and I want to make sure that the cause is not ADSM
before I involve anyone else on this. Background info: NT 4.0 environment,
running ADSM server ver. 2 backing up 24 servers. Running ADSM client ver.
3 on 4 servers.
I've noticed that the cahce hit pecrent keeps dropping gradually over a
period of time. The only way I can fix this is stopping and starting the
ADSM server. I have increased database buffer pool, per the ADSM manual
suggestion, from 512KB to 1014KB. The cache hit percent is currently at 77%
(I stopped and started the service 2days ago). The cache wait pct is 0.
The total buffer requests are very high considering I just reset the buffer
pool two days ago:114,983,514.
When inventory expiration runs, I've noticed that it takes anywhere from 5 -
8 hours to run. In the past it never took more than 1.5 - 2 hours to run.
Another anomaly: scheduled backups start at 2 a.m. in the morning. When I
come in at 8:30 a.m. one or two of the clients running ADSM ver. 3 client is
still in process. In the past, the backups were done by 6 a.m. No, data
has not increased. In fact, the summer is our slow time and backups should
be going a lot faster since the traffic on most of the servers is limited.
School starts in two weeks and I shudder to think what it will be like if I
don't find a fix for this problem.
Can anyone tell me what the problem is? I want to be able to pre-empt any
problem before it gets out of control. I want to be sure that this is not
an ADSM problem before I start looking at the network.
Any suggestions would be greatly appreciated. Thanks,
