db connect on BW which is on unix for sql server

Dear Experts,

I need to dbconnect SQL server database from SAP BW(which is on Unix and Oracle).

As I know,I need to install dbsl for unix(dbmssslib.sl)

But I don't know how to install sql server client on unix server.

I search the SDN,Found that----"You need to install the BI java connectors.

Relational DB's: you need to install the BI JDBC connector ,once u r done with it you should be able to connect any rdbms.

"

Is it right ?

Anybody help me on this.

Thanks a lot
