initi.ora permission

initi.ora permission

I am using Oracle Enterprise Edition 11g (11.2.0.2.0) on red hat linux.

        2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

Oracle umask is 0022

The permission of spfile.ora is

-rw-r----- spfile.ora

When I generate init.ora file using

create pfile from spfile;

The permission of init.ora is

-rw-r--r-- init.ora

My security requirement requires permission to be:

-rw-r----- init.ora

Is there a an Oracle setting to limit the permission on init.ora to 640 when genrating init.ora using

"create pfile from spfile;" or should I follow the command with a Lnix command " chmod o-r init.ora"?
