Database Repository

Hi,

What we are searching on resides in more than one database outside CM machine?. How can this be accommodated?

If we want to index a database that is resides in a windows or UNIX machine, and use TREX to search in this database, what is the required repository manager? And how can we set the database as a data source.

Note: We don't want to save or move the content of our database to the CM Databases.

We use UNIX for EP and our databases are in windows machines.

Thanks in advance...
