Vee_Mod,

We are running Peoplesoft on a mainframe using DB2 database platform.  In the current implementation, we are extracting from the mainframe using Ab Initio and landing in a set of staging tables in a DB2/AIX platform.  
we are asking if we could read the data directly from the mainframe using ODBC connection to the mainframe.  PLease reply ASAP!

You can, but you need to get either DB2 or DB2 Client or AIX.  The ODBC (and JDBC) drivers are supplied with the product.

Now, if you are running z/OS depending on requirements you can also extra data from DB2 using FTP.  I have not done it, but I do know that you can setup the FTP server on z/OS to connect to DB2 and then some how use GET/PUT to extract/insert data.

From that, it seems that DB2 is on the mainframe and DB2 is on AIX. However:

Why would you want to use ODBC with DB2 on both ends? Why not just use straight DRDA?

Tom, I am asking specific question about ODBC use in this case. I do not have DRDA available for this operation. ODBC is answer i am looking for. Thanks.

You do realize that even the DB2 ODBC driver uses DRDA under the covers?  ODBC provides the API for the program, the ODBC driver talks to the database in a way the database understand, which in the case of DB2 is DRDA.

Again, you need to get either DB2 or DB2 Client.  There are some products, like Toad (http://www.toadsoft.com/toaddb2/index.html) that comes with a copy DB2 Client.

if you want to access db2 on a mainframe from aix using odbc you will need to buy a middleware product such as db2 connect by ibm

if you can use jdbc, then the jdbc universal driver which comes with a db2 client installation for aix will allow you to communicate with a mainframe without the need for db2 connect

But he apparently _has_ DB2, both on z/OS and AIX.

I'm unfamiliar with DB2 on AIX, so I'm surprised that DB2 on AIX has no available connectivity to DB2 on z/OS. I would have hoped that IBM would provide DB2-to-DB2.

DB2 on AIX does come with everything needed to connect to DB2 on z/OS if you are talking straight to DB2 or using JDBC.  I'm not sure about ODBC though.  I always associated ODBC with Windows, not *nix platforms.
