RE: Replication?Paula,
Good point on using CTAS parallel nologging. However, I assume that the processing on the local server does not produce so many records so as to make the PL/SQL over db links noticeably slower.
Large PL/SQL operations over a database link have always seemed problemmatic. What if you were to do a CTAS unrecoverable, parallel to read the local table back into the MAIN database then processed with PL/SQL into the "MAIN" table?

Subject: Re: Replication?
You could use relication but it's not absolutely necessary. You could do something like this
On Server:
Run a query: SELECT * FROM MAINTAB
If they like it, issue INSERT INTO LOCALTAB_at_LOCALMACHINE SELECT * FROM
MAINTAB;
OR From the local machine : INSERT /*+ APPEND */ INTO LOCALTAB SELECT * FROM
MAINTAB;
When done with the edits, you can merge with the main table. If the changes
are exclusively done by a single user, you could
This operation will be much simpler than replication.
HTH.
