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,

I have made the changes in init.ora file , saved it , then run the comand "startup" from sql> prompt.. But same error.

Do i have to do anything else after modifying these parameters

Thanks

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
