Have u tested this connector with the VSAM and pl1 as there is a difference between VSAM and cobol files.
VSAM files are files that have index structures associated with them. The indexes are embedded within the data file. one needs to access such files through an access layer to propery read/manipulate the data.
But i've already looked into the Middleware you mentioned from datadirect. I will check this Microsoft Biz Talk and let you know . Also you mentioned EBCDIC file i think we currently are not working on that.
For DB2, you need an ODBC driver. There are a number of drivers available, from IBM, MS, DataDirect and other vendors.
For direct DL1, you'll need some middleware like the VSAM example. DL1 does not provide a relational view out of the box. You can use the IBM Federation Server and there are other vendor solutions available to create an "SQL View" of DL1 databases.
A typical approach for DL1 without middleware is to write extract programs to extract to flat files and do the QV load from there.
