Oracle Replication not pushing Data as needed

[pshetal]

Hi!

I have just started on a Oracle DBA Role and need help with fixing Replication.
Problem: Replication has been set up and is running, however data is not being replicated properly. Only some changes make it to replicated tables.

Replication setup is like this:
1 Master Group called - "GROUP1", Site - HLCAPROD.WORLD
376 Registered Materialized Views

Administrative Job - scheduled to run every 10 minutes.
Purge Job - runs every hour
Push Job - should run every 10 minutes but fails

I am at a beginner level as far as replication is concerned. Please advise:
1 -How I can gather more information about the way replication is setup?
2 - How can I refresh all the data on replicated site from the Master Site
3 - Is it possible to SYNCHRONIZE the Data from Master?
4 - Any links to Online resources on the matter?

I will greatly appreciate all you assistance in this issue>

Thanks
Shetal

Oh! One important detail I missed is - this is running on Oracle 8.1.7. Oracle Management Server is not set up, I am able to connect directly to the DB only - thru Replication Manager or EM Console.
