How to prevent high memory usage for Oracle RDBMS Kernel Executable?












1















I had set up Oracle DB 12c to my computer a few days ago and it slowed my computer down badly. I noticed that is causing high memory usage today. This usage stems from Oracle RDBMS Kernel Executable as you see in the picture. What can I do for this?

EDIT:



I tried to restarting the service which is called OracleServiceTEST but it didn't give a solution.

    How have you identified this is a leak & not simply high but valid memory usage?

  • @Tetsujin We set it up to different computers. It didn't affect them as in this computer. I am not sure but it seems like leak in this computer.

    It's only a memory leak if it's not actually doing something valid with the memory. As it's also creating disk usage (see the 0.1mb/s) it seems it maybe actually running a query (abet slowly)?

  • You still have not specifically indicated how you determined there was a memory leak. If there was a memory leak in the version you were using, it would affect all your instances of that version, instead of just a single instance. A memory leak is a programming error, what you describe, is simply high memory usage.

back up the data in DBS folder of your oracle home. Then run the following commands when connected as sys as sysdba.



Show parameter sga; -
you will see the size will be around 2.5G change it to desired numbers.



Below is an example:



Alter system set sga_max_size=1200M scope=spfile;
alter system set sga_target = 800M scope=spfile;
Shut immediate
Startup


Then check for show parameter sga and you will see new values .
