Setting ext3 to journal

Question

Hi all,
Oracle 11g R2, ELinux 5.2
I have my Oracle database data files stored in a disk formatted with ext3 file system.
I have read the following statement:
"ext3 has three journaling levels that may be set with in the options section of /etc/fstab: data=journal, ordered, or writeback.
Setting data=journal is the fastest and most reliable."
My question is:
Based on the statement above, is it good to change the /etc/fstab so that the mounted file system journal is set to "journal"?
If the answer is yes, how can I do that?
Thanks in advance.
Following is copy of my fstab file. Db files stored in /u02 and /u03:
[oracle@srv100 OPatch]$ cat /etc/fstab
/dev/VolGroup00/LogVol00 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
/dev/VolGroup00/LogVol01 swap                    swap    defaults        0 0
/dev/sdb1               /u02           ext3    defaults        1 2
/dev/sdc1               /u03           ext3    defaults        1 2

Dear ahb72,
What happens when you edit the /etc/fstab?
$ vi /etc/fstabWe have an NFS mount (external) on another unix box and we configured it on the /etc/fstab on the unix and we also configured the sharetab for the external directory. We also use vi to edit the sharetab and run the shareall command to share the external directory for the usage of the /etc/fstab on other unix systems.
So what i have said was most verbose, simply i want to add you can edit it in my opinion. I have never seen an impact.
Hope That Helps.
