VSAM Redirector
The VSAM Redirector is a new VSE/ESA connector, introduced with VSE/ESA
2.6.The VSAM Redirector allows you to redirect all requests to a certain VSAM file into any other file system or database on any other
For example you could use the VSAM Redirector to synchronize a VSAM file with a DB2 database running on a Windows. By using the VSAM Redirector your existing VSAM programs doesn't require any revisions.
The VSAM Redirector makes use of a so called VSAM Data Access Exit (VDA). This exit intercepts all VSAM requests. The exit gets control at OPEN, CLOSE, and for all data requests (GET, PUT, INSERT,...).
A configuration table is used to define which VSAM files are being "redirected". The VSAM Redirector Client on VSE forwards all requests against a redirected file to the VSAM Redirector Server which then handles the request.
The VSAM Redirector Server is a Java application. It can run on any Java enabled platform.
