Just wanted to post a follow up to my earlier posting. But first I want to
thanks everyone who took the time to respond with feedback.
The reason ulimit -a is only showing one gig form memory when the
max_per_proc_address_space value is four gig is due to the fact that the
server only has one gig of physical memory. I opened an iTAR with Oracle to
inquire why their installer was posting a warning message to my screen
recommending at least two gig of memory (when the Oracle 9i Tru64 install
doc only mentions a minimum of 512 physical memory). The response I got was
mostly "we aren't sure" but they think if certain ulimit values (including
memory) are not set to "unlimited" the warning message will appear during
the install.

Subject: ulimit - memory
I need to apply an Oracle patch on a V5.1 Tru64 server that I recently
became responsible for. Oracle says I need to increase my data and memory
ulimits. I was able to increase the data limit, but when attempting to
increase the memory ulimit I get:
server prompt> ulimit -m 2045680
ksh: ulimit: exceeds allowable limit
It is my understanding that max_per_proc_address_space is the kernel setting
for the hard limit, but it is set to 4,294,967,296. Searches on Google and
Oracle's knowledge base have not been fruitful. What am I missing? Thanks
in advance.
