Re: free memory
You don't have to worry, You can read about sched, vhand, lotsfree, desfree, minfree, etc. Search for HP-UX Memory Management under /docs.hp.com.

Re: free memory
Oracle Financials can be a real memory hog. Our production box here has 12 Gb of RAM in it, so you might consider bumping up the RAM in your development box. You can talk to the DBAs about reducing the size of the Oracle SGA (I think that's the term), but they might not be able to give up much room.
If they are also running the middle tier for Oracle Finanacials on this box, take a good look at their web server. I've been able to track some of their web programs and find memory leaks in them. To do this, I used the ps -el command and tracked the process size every 10-15 minutes through the day.

Re: free memory
i agree with john .
set the value of the dbc_max_pct to 10 ( its 10 % for the buffer cashe )
i m sending you also the pdf for handing the memory .
here is some info about the buffer cashe
dbc_max_pct
dbc_max_pct defines the maximum percentage of memory to be used by dynamic buffer cache.
Acceptable Values:
Minimum
2
Maximum
90
Default
50
Specify integer value. For more information, see Specifying Parameter Values.
Description
When the parameters bufpages and nbuf are both set to their default value of 0, the size of the buffer cache grows or shrinks dynamically, depending on competing requests for system memory.
The value of dbc_max_pct sets the maximum percentage of physical memory that can be allocated to the dynamic buffer cache.
It is possible to set both dbc_max_pct and dbc_min_pct to the same value, 12 for example, and create a kernel that uses exactly that percentage of physical memory for the buffer cache, regardless of the size of physical memory.

Re: free memory
We do not have an EMC array on this system.
The disk is an OSS RAID array with only 128Mb of cache.
Eran, I am unable to open your pdf file.
Thanks for your responses.

SolutionUNIX95= ps -e -o vsz=Kbytes -o pid,args=Command-Line | sort -rnk1 | more
Note: this is a single line (may be folded on this web page) and the UNIX95= ps is not a typo. It temporarily defines UNIX95 for the ps command but does not define it for any other program. Check the ps man page for other -o options.

Re: free memory
The command works and I found that
/opt/perf/bin/scopeux is taking 289.9Mb.
This is the Measureware collection.
I stopped MWA and restarted it.
It is only taking 2.9Mb now.
Would this be an indication of a memory leak,
or is this normal for MWA?
Is there an HP course that would teach really useful commands like this? Would it be covered in the Systems Internals Course, Inside the HP-UX operating system?
Thanks,
Eileen
