Hi All,
I am relatively new in Oracle Database administration. I was going through the Oracle Concepts - Memory Architecture where I came to know about Granules and v$sga_dynamic_components.

When I queried this view I am able to see Shared Pool, Large Pool and Buffer Cache with granule size of 16MB. However I am not able to see Java Pool and Log Buffer? Can anyone explain the reason behind this?
Java_Pool has been defined in the init parameter file.


Thanks in advance
Sandi

Always post your version.
This view has to do with ASMM. Did you enable it?
>>Java_Pool has been defined in the init parameter file.
To enable it, you are supposed to use SPFILE not PFILE
and
set SGA_TARGET.

Hi,
Sorry for not including the version. I am on Oracle Enterprise 9.2.0.6.
I have put JAVA_POOL_SIZE in init parameter and the same is getting reflected when I query v$parameter.
I could not understand why it need to be defined in spfile.
SGA_TARGET_SIZE is also set in init file.

Currently I am not using SPFILE.
What did you mean by ASMM??

Can you please elaborate?

Thanks
Sandi
