 Hi All,
Can you please explain the use of LARGE_POOL_SIZE parameter? Is this used only in shared server configuration?

Thanks.

yes it is used in shared server mode only. in shared server mode the session information,cursor information goes to shared pool & is not there with pga. so to better tune shared pool we need to configure large pool whose size is set from parameter large_pool_size

Thanks for reply.

It means it is not necessary to allocate large pool size in shared server as it can take memory from shared pool.


Thanks,
Vasu

Hi Vasu,
as u asked for Lard_pool_size, this may be used in any mode i.e. Shaerd server mode or Dedicated mode. This is optional and generally used for large operations i.e. RMAN, long running batch process.Java_pool is also optional and used for java objects to be stored in memory at run time.

Large_pool_size is configured just to avoid the fall in hit ratio.
