*********HPUX 11.11 with oracle 10g *************
i have an rp4440 running HPUX 11.11 and oracle 10g..physical memory is 8GB .swapmemory utilisation is always very high (total line in swapinfo 90%), where as device swap utilisation is only 3%,but i dont find any page out happening and few % of physical memory is also free ..My queries are below while looking in to found my SGA is 3GB and shmmax is 4GB..
1-Is it necessary to set SHMMAX equal to the value of physical memory ?..
2-dbc_max_pct set as 50 and dbc_min_pct 5% ..what is the recommended value for hpux 11.11 running oracle 10G
3-does anyone having pre-requisite for installing oracle 10g on HPUX 11.11 ,Pls share to me

U should follow the oracle 10g prerequisite.
Pls download oracle 10g installation guide from oracle site and follow the instruction.

Re: *********HPUX 11.11 with oracle 10g *************
You should probably reduce the max to 5 to 10%. You want the SGA to use that space.
>I am getting not enough space errors. should I need to add more swap in this system?
Yes, preferably more RAM. Or you need to reduce the SGA or stop running as many processes.

More RAM maynot require--because physical RAM is not completed utilised ..still few % physical RAM is avl ,but swap utilisation getting High ...I keeping swap space 2 times of physical RAM may solve the issue

If you are out of swap, you are out of RAM.
>I keep swap space 2 times of physical RAM may solve the issue
Yes, if you can't afford the RAM.

2. Increase shmmax to maybe 7Gb
3. Get your 11.11 upgraded to 11.23
4. Give us a list of your other parms, cause I'm guessing they could use some attention.
Oracle:
Oracle will require that you increase your maxdsiz. Yes, you must increase it so Oracle 10g can be installed...BUT!!!...you do not have to keep it at that setting. You can reduce it back down after the install is done and it will run fine.
Regards,
Rita

The maxdsiz settings aren't going to make a difference in system memory usage, except to stop memory hogs. So by reducing maxdsiz, your applications may not work.
I.e. applications don't usually query maxdsiz and change their actions like they do for shmmax.
