Are you sure a propely congirued TSM serve with 4 instances and 6 GB of RAM will actually have room for a 5th. IMHO you shouldn't run more that two. There are a few TSM tech docs that explain the way memory is used based on the those if you properly configure your buffpool you will end up causing memory constraints on your server which will cause problems just going to a 3rd TSM instance. Of course you could go to more 3 or more and limit their bufpools but then you may run into TSM performance issues. Add to that the number of handles on the system that get used. From this doc http://www-1.ibm.com/support/docview.wss?rs=663&context=SSGSG7&q1=TSM+Server+handles&uid=swg21112140&loc=en_US&cs=utf-8&lang=en the following may be of interest to you: For each buffer pool page, the server uses four conditions. This means a BUFFPOOLSIZE of 32768 uses 40000+ conditions and 80000+ handles initially. The handle count can grow to 120000+ over time as the conditions are first used (CRITICAL_SECTION entered).
Still here is a doc that tells you how to install TSM on Windows without using the wizard. I've never tried to see if will stop you at 4 http://www-1.ibm.com/support/docview.wss?rs=663&context=SSGSG7&q1=TSM+Server+Windows+4+Instances&uid=swg21046089&loc=en_US&cs=utf-8&lang=en Steve Harris <[EMAIL PROTECTED]> wrote: Hi all. I'm designing a TSM solution for a client. Servers are a couple of beefy Intel boxes - 4 way Xeons with 6GB of memory. This user is government so there is a long retention period required and the databases are big and going to get bigger. I was looking at a two way Windows cluster (2k3 datacenter edition, if it matters) solution with 5 instances, a combined config manager/central database backup/library manager/event manager and four "worker" instances, basically the same as each other but with the nodes shared around to balance the load. Of course each of the cluster machines would have to support the whole shebang at some point, for maintenance and in case of extended outages (eventually it will be a geographically separated cluster for serious DR capability). Now it turns out that you can't create a fifth TSM instance on a windows server in the usual manner - the option to do so in the management console is grayed out when there are four instances. I'm told that this is a documented limitation, but I can't see where it is documented, despite some serious searching. If any of you know where this is written can you please advise? Does anyone know where this limit is coded, or how it might be circumvented? The TSM registry structure is fairly simple so manually creating the appropriate files and registry enties might work if I can't somehow trick the wizard into action. Please let me know if you have tried this and what the outcome was. IMO this artificial restriction is a danged good reason to use Linux rather than windows.
