I would like to set up linked servers to DB2 and AS400 in SQL server and update the table in these two databases via stored procedures in SQL servers.

I have read articles on Microsoft site which indicate installing Microsoft Host integration server and use SNA server 4.0 Service pack 4.0 to

configure DB2OLEDB drivers.

Could any one suggest how do go about doing this.

Do I need to buy Host integration server or is there any other way to do it.

your help is much appreciated
