Mainframe-How to Modernize Batch Process (2of 3) ?

    As part of modernizing batch process,you have now the following capabilities on Zo/s.
  • Selection of Language:Cobol,PL1,Assembler are native languages.Now, Zos supports JAVA,PHP
  • Functionality by Runtime Websphere XD:Compared to stand-alone batch, a run time such as WebSphere XD Compute Grid can offer additional functionality through the Java EE model, for example managed security
  • Platform independency: If you want independency you can achieve it through JAVA/PHP instead of Cobol,PL1,Assembler
  • Accessing ZOs data: Java programs in stand-alone batch, CICS, IMS or DB2 stored procedures can access z/OS data sets and VSAM files using specific classes, and IMS and DB2 data on z/OS using a native high performance JDBC driver
  •  Stand-alone Java batch or Java in IMS cause a JVM startup for every job. If the jobs are long running tasks, this is negligible. But if you have many short running Java batch jobs, you might consider WebSphere XD Compute Grid or a Java DB2 stored procedure, which efficiently reuse JVMs.
  • PHP only allows access to z/OS UNIX System Services files and DB2 on z/OS. There is no support for accessing MVS data sets.

ZOS offers a lot of excellent capabilities to implement state of the art batch functionality.
