Loading Oracle, getting HP-UX error:28

[Leo Cusson]

I have place the default parameters for the semaphore, there is one exception,
could not find "shmmin". Here is the error;

// *Action: Check errno. Verify that system is configured to have semaphores.

Here is what I did with the semaphores;

Modified Kernel Configuration Parameters (pg 2-5)
recommended
Name was oracle Description
semmni 64 70 Number of Semaphore Identifiers
semmns 128 200 Max Number of Semaphores
shmmax 67108864 1073741824 Max Shared Mem Segment
shmmni 200 100 Number of Shared Memory Identifiers
shmseg 120 10 Shared Memory Segments per Process


Any suggestions what my problems is???

Run the command 'ipcs -sa' and total the numbers in the NSEMS column. Add to
that number the value of the processes parameter from the init.ora files for
each database you have on that server. Set the semmns kernel parameter to this
number at a minimum.

Better yet do what I've done, using SAM, navigate to the Configurable
Parameters area under Kernel Configuration and 'Apply a Tuned Parameter Set'
appropriate for your environment. You can tweak your kernel settings from
there and be fairly confident that you won't encounter this type of error
again.

Hi Leo,

The way to go about resolving this issue is configuring your kernel share
memory items to larger values. You can also read these topic from the IT
resource Center: "Oracle: configuring Oracle 8.0.5 on an HP-UX 10.20 system"
and "Understanding Shared Memory on PA-RISC Systems".
You can also look at my attached kernel configuration from my K580 server.
