I'm afraid I really don't know much about your distro, so I'll leave that to people that actually know what they're talking about. Setting (or un-setting) a bit, however, goes like this:
Code:
# chmod (who)(operation)(what) <file>
Here's what that means: To set a bit, first determine who you want to set it for: the (u)ser, the (g)roup or all (o)thers. Then determine the operation, or what you want to do: Do you want to add (+) or remove (-) the bit? Finally, what bit do you want to add or remove? You can do (r)ead, (w)rite or e(x)ecute bits.
You want to remove (-) (w)rite permissions from the (g)roup. That gives you:

Before you start get a complete listing of all files you intend to change, before you change anything. Keep it in a safe place.
This looks like an Oracle distribution of Red Hat -
If that is the case, they mean any executable file under the /usr tree that is owned by root. Not necessarily directories. /usr directories should be owned by 0:1 (root:bin) or root:[some other number under 20] and should already be rwxr-wr-x, except some oddball man pages
Also, the oracle executables in $ORACLE_HOME/bin, as an example:
/oracle/home/product/11.0.2/bin.
If you have weblogic, apache, etc then the same thing for each independent installation - probably the files are in /opt, they may also be in /usr/local/bin.
Be careful. You can break applications pretty easily if the app legitimately needs to write some files. So look at every file permission and be sure they are executables and not links:
