Rajamurali said...

This article looks good, but if it includes the unix shell commands for archive logs it would great for people who are new like me.


Datriya... said...

Very usefull article, by the way if it include UNIX script for tuning OS it self and shell commands for other need, would be usefull to all oracle DBA and System engineer.


manoj said said...

Ramesh Kumar said...


It is really usefull to all Oracle/UNIX administrators.
I observed one mistake in this article. Under the "OS Users Management" section, meaning of "-G" of option with useradd command is given as " -G indicates Primary Group", but it indicates not the primary group instead it indicated supplement/secondary group of a user.

I believe in chmod the 6 stands for rw (read write).
Because i'm getting the following o/p:

$ chmod 666 monish.txt
$ ls -lrt monish*
-rw-rw-rw- 1 oracle dba 0 Feb 27 19:34 monish.txt

Please update me on this.

venkat said...

6 (u+wx) 6 (g+wx) 6 (o+wx) write + execute

There is mistake in this I guess.

A user cron file should not has a username field(created by crontab -e), only system crons like /etc/crontab and files in /etc/cron.d/* have username fields.
