Global Area space full

[dayanandnaik]

Hi,

I encountered this problem,

Global swap area is nearly full.

I used glance to see, it gave a red alert... on the above message. What could cause
this problem. V r running oracle, nnm on hp-ux 11.00 on HP visulize 3600 workstation

Thanks and Regards,
Dayanand Naik

The first thing I would look at would be your kernel parameters. Here is what Oracle has to say about setting the kernel for an Oracle database on an HPUX system:

Example on HP-UX (relevant sections only):
------------------------------------------
Semaphore Related Parameters
maximum value for semaphores(semaem)= 16384
Semaphore map(semmap)= 4098
number of semaphore identifiers(semmni) = 4096
total number of semaphores in the system(semmns) = 8192
number of semaphore undo structures(semmnu) = 1536
semaphore undo entries per process(semume) = 512
semaphore maximum value(semvmx) = 32767

Shared Memory Related Parameters
maximum shared memory segment size in bytes(shmmax) = 536870912
minimum shared memory segment size in bytes(shmmin) = 1
maximum shared memory segments in system (shmmni) = 512
maximum shared memory segments per process(shmseg) = 512

I also changed my maxdsiz parameter to 1073741824. This may differ from your system.

Dayanand,

You can check how much swap (paging space) is actually being used with the [tt]swapinfo[/tt]

I would think you probably need to increase the amount of swap (paging) space available on that system. As a (very) rough rule of thumb I suggest your paging space be 3 times the size of your physical memory. Find some unallocated disk space and then have a look at the [tt]swapon[/tt] command; go careful please. Mike
