I'm getting ORA-4031 error :unable to allocate 6666240 bytes of shared memory("large pool","object","hash-join subh") error.
My current shared_pool_size is 220 MB. I want to set it to 320 MB. I'm running oracle 9i Rel 2 on linux 7.2 .C Can i adjust this parameter dynamically, then the DB is up and running , if yes, how can i do that. Can any help me with the steps please. I want to adjust the shared_pool_reserve_size also. Please let me know the steps asap, as all my users can't connect and are waiting. or else DO i need to restart my DB after setting in init.ora file?
Thanks in advance

that would be ure kernel parameters in /etc/system which need bumping up, shared memory and semaphores

Have you tried setting large_pool_size. Don't just go on increasing size of shared_pool_size.
Set PARALLEL_AUTOMATIC_TUNING to true even though you are not going to use any parallel clause. Because of this Oracle will automatically calculate value for large_pool_size.

thanks for your immediate response, even though i set my shared_pool_size to 320Mb, its not working. My large_pool_size is 10MB. my DB version is 18.104.22.168.0, Do i need to set the parameter parallel_automatic_tuning=true in my init.ora? and what about the large_pool_size.

are you using MTS

Just set parallel_automatic_tuning to true and do not set the value for large_poo_size... Oracle will automatically calculate value for large_pool_size...

we are not using MTS.
Sameer, i set the parallel_automatic_tuning=true in my init.ora file and restarted the DB, and still giving the same problem.

If not MTS, then it won't be of much use.. Sorry I forgot to ask you before.. what are you other settings?.. what is the value for db_cache_size?.., Are you pinning large objects?
