A mainframe operating system is networking software infrastructure that allows a mainframe computer to run programs, connect linked machines, and process complex numerical and data-driven tasks. Modern mainframe design is generally defined by redundant internal engineering, extensive input-output facilities, strict backward compatibility with older software, high hardware and computational utilization rates and high stability and reliability. Well-known operating systems include IBM z/OS, z/VM, zTPF, z/VSE, OS/390, and their predecessors, along with MCP for Unisys ClearPath, and NonStop OS/Guardian on HP/Tandem, and questions regarding the IBM midrange operating system called IBM i, OS/400, and i5/OS.

Hi All,

We are doing a small POC to migrate MF screens to JAVA based webpages. As a matter of fact, we have created COBOL SPs to call relevant MF DC online programs. In case we need to call COBOL SP, what approach do JAVA team has to follow.

NOTE : IBM MQ is not supported by customer
              IMS DC (IMS is the online component of my customer. IMS and DB2 databases are used by administration system) is not suggested as it needs additional work
              Webservice / business services help should not be used.

What could be the approach do we have to follow?

P.s : I am neither JAVA expert nor Mainframe expert. Since I am managing a project, trying to get suggestions from various areas.

Moreover I heard something like wrapping COBOL stored procedure with DB2 so that it can be converted to DB2 SP(Do we have any approaches like that). In my customer's IT landscape they can call DB2 SP by using ODBC driver.

I am looking forward to see responses from experts.

Regards,
Krishna

the application I am using is a web based application in mainframe,its a IBM product called Tivoli output manager,there I use TPX in tpx session comes in layer in tpx we use TSO session and DB2 as database
