Does any one know how I can get the LTO version to appear at the end of
the volume numbers in TSM?

If I q libvol the volumes in my old library & stg pool have "L1" as a
suffix, but the volumes in my new library & stg pool don't. Any ideas
how to switch this on for my new library or stg pool?

I kinda have to agree in that I have seen weirdnesses when increasing
the buffpoolsize as per the recommendations.  On a fairly horsey Dell
box with 4GB of RAM and running the latest RH SMP server, when I
increased the buffpoolsize to 512MB, everything seemed to slow down,
when it comes to the TSM server responding to administration type
requests, etc.

When it comes to cache/ram sizes, I have see other situations (not
specifically TSM) where the recommendation was to NOT make the allocated
memory too large since it caused high CPU).

Re: Cache Hit % below 99%






?

For a long time I have believed (fairly sure originally told by IBM)
that the method is to increase the buffpool size untill cache hit goes
over 99%

Talking to a colleague, we really don't see how reducing bufpool size
can increase the cache hit%

Can anyone explain what we are missing?

Thanks,

Matt.

Hello!

I just wanted to thank everyone for suggestions and help with this
matter!
I changed the bufpoolsize to 419430, which is 10% of the physical
memory, and then reset the bufpool and now my cache hit % is 100%.  At
this point, until I see otherwise, I am going to conclude that I had the
bufpoolsize setting too high at 524288.  I will continue to monitor the
cache hit % of the database, but I believe the problem to be solved.
Thank you again!

What is your buffpool setting? Run "query option" and look for the
buffpoolsize. Look in the dsmserv.opt file and read the comments about
this parameter, then look in the server manual for this too.

Cache Hit % below 99%






Hello All!

I have noticed that the cache hit % is below 99%.  This is a newly
defined TSM 5.2.2.5 server on an AIX 5.2 OS.  Are there any special
parameters/definitions that could contribute to the percentage being so
low?  Thanks!
