Is there any easy way under Solaris 8 to limit the amount of physically memory seen or used within a Solaris server.

I have a server with 4 CPU's and 16GB memory but wanted to run a benchmark with a simulated memory of only 8GB can I reduce it using Solaris only, or do I have to either physically remove DIMMs or can I issue an OBP command ?

I am not interested in what I could or could not do with DR in a partitionable machine !!

If I was doing this under AIX I know I can issue the "rmss" command from the OS which is part of the performance toolkit, probably issues a MALLOC and grabs the memory so nothing else can use it.

Off topic but have you ever put MALLOC in an infinite loop?

Dave,

AFAIK, you need to install Sun Resource Manager - you may be able to get a try before you buy copy (not sure).

cfgadm?

not sure if you can disablem memory components or just the enclosure they are in, e.g. the whole lot.
