Description:

The QTM application which is a part of AFC web services aims to provide significant cost savings to the organization by reducing and eventually eliminating the read only traffic from Mainframe system MCH. The application has the capabilities to replicate any changes made to the Mainframe database to a Oracle database. The application provides Web Services interfaces that are backward compatible with the interfaces currently used by consumer applications. The application is also capable of detecting replication failure or delay and performing horizontal and vertical switchover between the Oracle database to DB2 on Mainframe or to Mainframe Web Services. The backward compatibility and switchover ability allows the consumer apps to work seamlessly with the new system without worrying about the cost and effort of migration and redevelopment. The application provides the following functions:

Replication of Mainframe data to Oracle

Database views and stored procedures to access the replicated data

Web Services that provide a backward compatible interface to access the views and stored procedures

Resiliency to switch over from one database to other in case of database connectivity failure

Roles & Responsibilities:
