How can I automate copying DB2 table data between remote Servers? I have two IBM DB2 servers at separate remote locations. 

I need to copy data from several tables on one database on the first server to another database in the second server. 

Previously I've used the IBM data studio tool to export the data and Replace Load it into the other table in the second server.

I am in need of a way to automate this.  Probably through command line shell scripts. 

How can I accomplish this?
I think you may have answered your own question. I would use command line shell scripts. Seeing as you are on Linux, you have several to choose from (sh, ksh, and perl to name a few).

Another thing that could make things easier is if you catalog the remote server and database locally. Then you can connect to it and work with it without your script having to worry about ssh'ing over to another box.
