PFILE Question

Posted on 2013-12-17

In the init file I have:
BB60.__pga_aggregate_target=2147483648
BB60.__sga_target=6442450944


*.os_authent_prefix=''
*.pga_aggregate_target=2684354560
*.sessions=2755
*.sga_target=7G
$

I entered the sga_target and pga_aggregate_target.  It appears Oracle entered the
BB60.__pga_aggregate_target and BB60.__sga_target=6442450944.
Just what are those top two entries?  I did not put them in. Which takes precedence?

Hi,

You are using AMM (Automatic memory Management) where Oracle can change the size of SGA and PGA. It stores the last value in the spfile so that if instance is restarted, it get back to those values.

Regards,
Franck.

Thanks.  So is oracle writing this info onto pfile?
These appear on top of the pfile.
BB60.__pga_aggregate_target=2147483648
BB60.__sga_target=6442450944

>>So is oracle writing this info onto pfile?

This was sort of answered in the first post:  "It stores the last value in the spfile so that if instance is restarted"

The answer is:  Yes.
