Designed, developed and supported the entire stack of the Adabas Replicator Java based Confidential Adapter from end to end into a high performance
Multi - threaded based system in Java.
Converted a single threaded source and Confidential system to a 24 by 7 dynamic multi source/ Confidential and engine system controlled and monitored via JMX.

Research & Development Fellow

Responsibilities:

I developed and supported various components of the EntireX Communicator and the Service Orchestrator/Mediator.
For the Relay Manger I wrote the entire Client and Server components in LE C and 390 assembler.
As a multi-tasking system it receives client request from Batch/TSO, CICS and IMS. USS shared memory and message queuing was used as the Inter Process Communication for z/OS and XPCC was used for z/VSE. The requested were then redirected to the Confidential software. Under CICS I wrote an OPEN API enabled TRUE to send the request to the Relay Manager and wait for the reply.
My contributions included the Java Object Gateway (JOG), the Extended Confidential gateway (XACI) and an Confidential .
The Java Object Gateway was a generic interface to any Java Object. Java reflection was used to create Java objects and call any method with the defined parameters that was defined in and XML document.
The XACI gateway uses the JOG to expose all the functions of the EntireX Java Interface (JACI) and the Confidential was an Interface into an Orchestrator Transformer object by using Java RMI. Additional development included a Java Connector front end to allow all adapters to run in a J2EE managed environment.

I also wrote a Java 3270 emulator GUI using Java swing that was used to run the CICS Transactions to capture and record the information needed to re-execute the Transaction.
