Hello,
We have a requirement to process VSAM mainframe files through WMB. I know there is a support pack available IA13 for WMB on z/OS where VSAM node comes. In that case I am assuming that this support pack only work with IBM mainframe ( z/OS). Will it work for any mainframe systems ( Non IBM) or is there any other way to process mainframe VSAM files from WMB?
Would appreciate your great answer.
Thanks in advance !! |

There are many ways.
Do you want to read the entire VSAM dataset through a message flow or extract a particular record?
Do you want to process one record at a time through the message flow?
Forget about "non-IBM" mainframes - (a) they don't really exist except in the minds of marketing people and (b) whatever they are they don't run z/OS. |

Hello,
I want to extract a particular record also I want to modify a particular record. |

VSAM is from IBM...so only exist in IBM Mainframe.
VSAM is a File type, in z/Os for example exist a some file types, Secuencial, VSAM(Sub Type:Secuencial, Key, RRD), Generationals,....
>>>Maybe in other Mainframe exist other files type.
Suppport pack IA13 have some examples. Copy and Run.

Assuming that you don't have WMB on z/OS. I would recommend this approach:
Have WMB send a MQ message to a mainframe queue with the index value for the VSAM read in the message data.
Have this queue trigger a transaction in a CICS region using CKTI.
Code the CICS transaction to read/update the VSAM dataset and respond back (this transaction may well already exist).
There is no way to directly access VSAM from non-z/OS WMB platforms - you have to use some kind of CICS trigger or CICS bridge.
If you don't have CICS (a) get a life! and (b) use batch triggering or IMS if you use that.
