file creation

himacs — Wed, 18 Mar 2009 09:46:17 GMT

Hi all,

I have a partition with oracle:dba as owner and group.umask is 022.when oracle user creates any file default permission it shows rw_-r__-r.
I want it to be rwx for owner and r-x for group by default.

please help me on this.

regards,
himacs

when a normal file is default created

its 666 and for a directory its 777

so when the umask is 022

666
022
---
644 which is rw-r-r-

Now for directory

777
022
----
755 which is rwxr_xr_x

so the present umask is fine, just because its file its rw_r_r.

because they are normal text files and have file permissions 0666 and with umask 0022 it gets 0644 which is rw_r--r--.

why do you need permissions 755 as those files are text files or log files.
I feel the present umask looks fine. Is there a reason you want to change.

hi manikandan,

thanks for ur reply.

i just confused..

but how we can set defualt permission for only files not dir.s which should not affect present umask.

I dont think there is a way, if I am not wrong. probably if you want to change permissions with a specific oracle directory you can have a script that changes the permissions of those directory files every 3 hours or something.

But which is the directory/files which you are looking for a changed permissions,
Are they scripts, text files, special files which need the twx i.e. execute permissions?

hi mani,

not for special files...simple files

if they are simple files why do you need execute permissions, rw should be fine.
But if still you need execute permissions and these files are generated out of the system, have a cron script that would change their permissions frequently.

one other thing you do atmost would be having the umask set with oracle user's .profile

as

umask 0022

With oracle running under its group we are providing permissions for owner and group and restricting for others.
