Rather than clearing /tmp, it would make more sense to resize it and move the MySQL tmpdir. I don't personally believe it is a good idea to use tmpwatch. It is better to resize /tmp and change the MySQL tmpdir location.
Here are discussions on doing both of those instead:

You can just execute to delete all session files but i would not suggest to delete recent files as users may get session file errors.
rm -rf sess*
rm -rf sess*
Alright, and may I ask like recent files.
such as if they uploaded index.php 1minute ago it will be gone?

You should change directory to /tmp fils and then execute command I gave. You need to make sure your working directory before deleting any files on the linux server. You can check working directory by using pwd command. Many script generates session files after every seconds. You can use mtime argument with the find command to search out little bit old files say 1 hour older. So if you delete them it wont cause much effect for your website.
root@server1 [/usr/src]# pwd
/usr/src
What do you mean change directory to /tmp files and then execute?

try some of the steps below, may be helpful.
1.) Stop MySql service and process kill the tailwatchd process.
2.) Take a backup of /tmp as /tmp.bak
3.) Create a 2GB file in the avaliable freespace
[root@server ~]# dd if=/dev/zero of=/usr/tmpDSK bs=1024k count=2048
쎀+0 records in
2048+0 records out
2147483648 bytes (2.1 GB) copied, 73.6908 seconds, 29.1 MB/s
[root@server~]# du -sch /usr/tmpDSK
2.1G /usr/tmpDSK
2.1G total
4.) Assign ext3 filesystem to the file
[root@server~]# mkfs -t ext3 /usr/tmpDSK
mke2fs 1.39 (29-May-2006)
/usr/tmpDSK is not a block special device.
Proceed anyway? (y,n) y

This filesystem will be automatically checked every 25 mounts or

5.) Check the file system type:-
[root@server ~]# file /usr/tmpDSK
/usr/tmpDSK: Linux rev 1.0 ext3 filesystem data (large files)
Note:-
6.) Unmount /tmp partition
[root@server ~]# umount /tmp
7.) Mount the new /tmp filesystem with noexec
[root@server ~]# mount -o loop,noexec,nosuid,rw /usr/tmpDSK /tmp
8.) Set the correct permission for /tmp
[root@server ~]# install -d –mode=1777 /tmp
[root@antg ~]# ls -ld /tmp
drwxrwxrwt 3 root root 4096 Feb 6 08:42 /tmp
( you may use the command chmod 1777 /tmp for doing the same )
[root@server ~]# df -h

/usr/tmpDSK 2.0G 68M 1.9G 4% /tmp
9.)Restore the content of old /tmp.bkp directory
[root@server ~]# cp -rpf /tmp.bak/* /tmp
10.) Restart the mysql and tailwathchd services.
[root@server ~]# /etc/init.d/mysql start
[root@server ~]# /scripts/restartsrv_tailwatchd
11.)Edit the fstab and replace /tmp entry line with :-
/usr/tmpDSK /tmp ext3 loop,noexec,nosuid,rw 0 0
12.) Mount all filesystems
[root@server~]# mount -a
Check it now:-
