JOB QUEUE PROCESSES NOT RELEASING MEMORY

edited Jul 21, 2009 11:38PM in Database Administration (MOSC) 7 commentsAnswered
Top command is showing the below values
real memory is 8Gb, this process has 17% of this, plus SWAP, but no jobs are running.

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND
27715 oracle 16 0 3425m 1.3g 1.3g S 0.0 17.2 134:55.28 2.0g ora_j000_EV01T3

when I investigated the job that is reported by the top from inside the database using heap dump , I found that it is taking a small amount of memory, so why the top is showing this values? is there a known issue about not releasing the memory back correctly by linux?

 

Hope anyone can help on this.

Howdy, Stranger!
