Ora-09925:unable to create audit trail file at DBCA

The command to view the memory sharing information is ipcs [-m|-s|-q]. By default, shared memory, Semaphore, queue information,-m lists shared memory,-s lists shared semaphores, and-Q lists shared queues. How is it clear? The clear order is ipcrm [-m|-s|-q] id. -m *** shared memory,-s*** shared semaphore,-q*** Shared Queue. Here is an example of an operation: View plaincopy to clipboardprint?

Shows that the current system has shared memory, shared semaphores, and no shared queues. Then perform ipcrm -m 262145 to clearly share semid=262145 shared memory. The execution ipcrm -s 884736 clearly shares the amount of semid=884736 shared semaphores. Finally execute IPCS view shared memory, Shared Queue, share semaphore information, found all gone, the above Ipcrm clear shared memory and shared semaphore success
