I am trying to query a table on IMS mainframe database. Joins doesn't work (query doesnt give error but at the same time doesnt show data, just keeps running) but the same joins work fine on mainframe. Is there a separate way in webfocus to query IMS databases which are on mainframe? Metadata is created obviously. Please let me know.
Thanks all..This message has been edited. Last edited by: Kerry,

It has been a long long time since I worked with IMS DB. IMS requires a mainframe PSB and ACCESS file to retrieve the data. During the GET/PUT process IMS sends the channel program physical cylinder and track locations for the data. I am thinking to accomplish this a WebFocus Data Server would have to be running on the mainframe.

The WebFOCUS IMS adapter only works on z/OS so in order to us it you must have a sub server installed on the z/OS system.
You cannot use a Focus IMS adapter (or any Focus adapter for that matter) with WebFOCUS they are completely seperate products from a license point of view.
The WebFOCUS IMS transaction adapter is a different beast to the WebFOCUS IMS adapter and can be run on windows or Unix platforms using IMS connect/OTMA as well as z/OS.
All the adapter documentation can be viewed in the online help for the WebFOCUS server

Because most IMS Data bases are tuned for transaction processing, I would be inclined to dump the data base and load a FOCUS or SQL Data Base. The odds are you performance would be a lot better.
The other approach is run an EDA webfocus data server on the mainframe. The performance is great because of the speed of the I/O.

Hi, We are licensed and do use the IMS interface on z/OS with no problems.
There is some set up work that your FOCUS & IMS installers have to do to make this work. 1. FOCUS SUBSYS has to be set up 2. Special IMS PSB should be set up
If you are not licensed, or do not want to set this up in your environment, your best bet is to use something else (e.g. COBOL) to extract to a sequential file and then use FOCUS to report off of that. If the data is stagnant and not too large, you can load this sequential file into some database format and use that for you reports.
