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.
