Welcome to the board, Pearl-chan. Now please sit down and take a deep breath
Mr. Sample and Dr. Sorichetti have between them pointed out most of the flaws in your post; I will only add that urgency on your part does not entail urgency on ours.
Sri Dhawan has provided a link to an example of a IEBUPDTE job; it may be that you will find it adequate to your needs.
If you cannot post the JCL and sysout for
technical reasons, we may able to talk you through that task. If it is for security reasons, you may be better served by asking for aid from your
senpai or your support workgroups; as Dr. Sorichetti points out, it is impossible for us to work blind.
Finally, if you tell us the task that you are trying to accomplish, we may be able to explain better ways of doing it; IEBUPDTE is a very old utility, and one that is generally not suitable for a typical developer.
