Access DL/I data from remote systems |
Core applications and processes based on DL/I databases with the requirement of integration of these applications in heterogeneous processes can now take advantage of modern functions implemented in VSE.
|
Overview |
To have real time access to DL/I data from a remote platform, the VSE Java-based Connector, part of the VSE e-business Connectors was developed to solve this business need. It is build of 2 components:
Access to the DL/I is done through the DL/I online nucleus via MPS. The VSE connector client contains interfaces to interact via PSB and corresponding PCB with the DL/I subsystem and data.
Real time Access to DL/I data:
-
from standalone applications
-
-
from Servlets, JSPs, EJBs, Applets
On the remote side the VSE Connector Client provides a program interface which can be exploited by any kind of program or web application. All kinds of DL/I requests can be performed, including CHECKPOINT and ROLLBACK.
|
Benefits |
Real time access to DL/I data from a remote system allows the integration of DL/I data into distributed processes and web transactions.
|
Software requirements |
The following software requirements must be meet in order to implement this solution:
-
VSE/ESA 2.5 or later
-
-
VSE Connector Server running on VSE
-
-
APAR PQ39683 for DL/I must be applied
-
Your CICS/DLI system should have all PSBs defined in the DL/I online nucleus DLZNUCxx and it should have an active MPS system.
-
Linux, Windows, AIX, Unix on remote system
-
-
Note: WebSphere is NOT required to run the VSE Java-based connector. However, the connector can be deployed into WebSphere as an Resource Adapter if you wish to access VSAM from a web application.
|
How to get started |
To get started, following Steps need to be done:
-
Start VSE connector server on VSE (release STARTVCS from the reader queue or create it from ICCF library 59, skeleton SKVCSSTJ).
-
-
-
Develop a program that uses the PSBs and PCBs to access the data you'd like to have access to.
Note: The VSE connector client contains descriptions and samples for accessing DL/I data.
