ORA-00838 error after increasing MEMORY_TARGET I've increased MEMORY_TARGET in pfile and then create spfile. I'm getting the same problem as before: 

ORA-00838: Specified value of MEMORY_TARGET is too small, needs to be at least 3084M


The memory_target in pfile is 3084M.

I've already increased tmpfs on /dev/shm to 5Gb. And no idea what to do next?
Set MEMORY_TARGET to at least the recommended value. 

SQL&gt; CREATE PFILE FROM SPFILE;
MANUALLY EDIT PFILE &amp; CORRECT MEMORY_TARGET VALUE
SQL&gt; CREATE SPFILE FROM PFILE;
SQL&gt; STARTUP


What OS are you using?
