What are various interfaces that are available in market to Integrate applications built on Mainframes
eg; In my previous shop we have an upfront system that comes data from a Unix box
And we have a front end application built on .Net and we used to have MQ-Series in our shop wherein we process data and kept in Queues and if the front end users wish to process the data they pick it from the Queues process it and place back on Queue
Could you please provide more information about various integrations
You are not going to get many responses with such an open-ended question. Mainframe interfaces is a very broad topic and could include FTP, SMTP, APPC, SOAP, and so forth. You would be better off asking at your site about the interfaces available there -- since the various interfaces can require elaborate set up and configuration, plus cost a lot of money, sites rarely install interfaces that they don't use. Contact your site support group.
