Erro: Insufficient swap or memory available
What's the best way to handle the error above? May I extend the targeted memory?

Re: Erro: Insufficient swap or memory available
How are you using the memory, i.e. are you using a virtual machine or vPar? Or are you using a single machine?
If you have loaded the machine and not specified enough swap then the machine will struggle, even if it isn't using it. HPUX reserves swap for the processes to swap from memory, even if it never has to.
A general rule of thumb is swap = 2 x memory.
Real memory for 64bit HPUX requires an absolute minimum of 512MB, though that in my opinion should be more than 1GB.

Re: Erro: Insufficient swap or memory available
physical and swap.
Either you have very less memory or u r running some very big processes???
Better to increase swap according to above reply.And memory atleast should be 1GB.

Re: Erro: Insufficient swap or memory available
Error could be caused by (as already stated) you did not allocate sufficient swap space.
Error could be triggered by incorrect settings on parms even when processing seems light.
Error could be triggered because you are running more than the system can handle in the best of settings.
Error could be triggered because you are running more than the box has physical memory to handle.
Error could be triggered because your DBA started up another "instance" without checking if the system could handle it.
....and the list goes on....
Supply details: System physical memory;kernel parms. You confirmed the SGA values, so you know they aren't running more than box can handle. Then we can help you better.
Thanks,
Rita

Re: Erro: Insufficient swap or memory available
In general,
Best way to deal with real memory shortages is to add memory.
If impossible, try and reduce the use of memory. Tune Oracle sga and applictions to use less, or run less services.
Its almost never a good idea to extend swap past 2 times RAM. As rules of thumbs go they apply to entry level systems. Systems with a large amount of memory can get by with less swap.

Re: Erro: Insufficient swap or memory available
A terminology correction. Disks aren't out of memory. They are out of space. (Perhaps their controllers might be. :-)
Only applications or the kernel are out of memory.
This is unrelated to your "Insufficient swap or memory" error.
