Sync data between 2 databases Oracle 10g I have 2 databases DB_LIVE and DB_NEW, both have different credentials. I have a Data Read access on DB_LIVE and I am owner of DB_NEW which is a completely blank and raw db provided to me.

I want to copy a table from DB_LIVE to DB_NEW and later keep syncing them. Another caveat is I only have PL/SQL developer and no SQL*Plus. Can someone please provide me pointers to it.
On the machine where you installed your database you should have SQL*Plus installed.

For your question. Create a database link from DB_NEW to DB_LIVE and use your Read Data user. Now you can query the data.
