Hi,

I am new to oracle .
I am getting the following error while strating up oracle.

% sqlplus "/as sysdba"

SQL*Plus: Release 9.2.0.4.0 - Production on Fri Mar 4 15:56:50 2005

Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.

Connected to an idle instance.

SQL> startup
ORA-04031: unable to allocate 95400 bytes of shared memory ("shared pool","unknown object","sga heap(1,0)","qmps connections")

Please help,

Thanks

In most cases this is either shared pool is too smal or is fragmented.
As this is happening when you start the database, I would look at 1st case.

Is this the 1st time you start this database ?
What are the shared_pool parameters in the init.ora file ?
Available memory on the server ?

Hi,

Has this database started before ? (or is this "never") If yes do you still have the init.ora file to compare with current for differences ?

What's the value of the kernel parameter "shmmax" ? run (as root) the following:
kmtune | grep shmmax

This should return a number larger than what you're trying to allocate. If not, it's time to make it larger. This may or may not actually stop you from allocating the memory - but it could cut it up into a lot of chunks.

What's more likely to stop you from getting there at all is maxdsiz - if you're running the 64 bit version of the database you need to review maxdsiz_64bit. You may also need to review the size of maxtsiz and maxtsiz_64bit - but that's less likely - but good to look at anyway.

You can look at all of your "max" type kernel parameters with:
kmtune | grep -i max
