Just e-mail: and include the URL for the page. On the other hand, you can also utilize the dbms_shared_pool package to pin large memory packages, or increase the availability of shared memory completely. Staring from 10g, Overhead memory is accomodated in shared_pool_size. For earlier versions, the trace file will be written to either USER_DUMP_DEST (if the error was caught in a user process) or BACKGROUND_DUMP_DEST (if the error was caught in a background

Please note that in case you specify a low value for SGA_MAX_SIZE, you will see Oracle bumping the value to higher value so as to accomodate high value of Overhead memory. Ensuring that MEMORY_TARGET or SGA_TARGET are large enough to accommodate workload can get around many scenarios.

You can read more about Shared Subpools in my earlier post Step5: Is Sqlarea consuming lot of Memory? Applications like Oracle Apps do not certify use of this parameter so also check with your application vendor if this can be used. e.g px msg pool consuming more memory - Shared Server Configuration UGA will be allocated from shared pool in case large pool is not configured. I've tried increasing sga_max_size from 140M to 256M and hope this will help things.
you should check alert log to prove/disprove it. –ibre5041 Mar 10 '15 at 12:32 you should also flush the whole shared pool, not just a buffer cache. –ibre5041 Mar This gives indication that Shared Pool is not appropriately sized.
