 8.0.5 32-bit on HP-UX 11.0 64-bit
Hi all !

I changed shared memory from 1 GB to 17 GB and my oracle stoped to work. I
could not connect to server with svrmgrl. After changing shared memory back
to 1 GB oracle started to work properly. I have no patches installed on
oracle server.

Can anybody help me with this issue ? What should I do ? I need to increase
shared memory limit but I want to have my oracle database running.

Thanks in advance

Marcin.

First of all : you should upgrade, as 8.0.5 has been desupported
almost a year ago.
Secondly, I don't think you will ever be capable of reaching 17Gb
shared memory in a 32 bit architecture.

Hi Baton/Marcin (who wrote?),

in your subject line you wrote that 8.0.5 32-bit has problems. Now, it is called
32-bit because its address range only has 32 bits width. That means, you only
can address 2^32 bytes of virtual memory per process, which is exactly 4 GB.

In a 32-bit mode you *cannot* access 17 GB of virtual memory by a single
process. It is a mathematical limitation in itself. However, several processes
together may map their virtual memory areas to different parts of the physical
17 GB memory thus exploiting all of it.

You put a truck engine into a Porsche and now you wonder the Porsche doesn't
move any more.

Hi again !

I forgot to add that my oracle server is using only 0,5 GB of memory.
