COBOL RunUnit

Multiple RunUnits in Java

• Compile the COBOL that you want to call. For procedural COBOL programs use the NOILSTATIC directive, which is the default. This enables any COBOL classes created to be included in a run unit.
• Any COBOL program or CLASS with instance data/methods can be used with multiple run units providing you do not compile with the REENTRANT or ILSTATIC directives.

Use RunUnit

• Either use the RunUnit.Call() method to call the COBOL class, or:
  • Make sure that any parameters are Java primitive data types.
  • Create an instance of the procedural COBOL program to be called.
  • Add the program instance to the new run unit, using the RunUnit.Add() method.
  • Invoke the program instance within the new run unit.
• Use the StopRun() method to destroy the run unit when you have finished with it.
• NOTE In OO COBOL programs in a mixed language environment, do not use static methods and data as they cause run-time errors.
• NOTE Ensure that data access is synchronized, as the run units will be executing in different threads.

Monitor RunUnit with Mission Control and CTF

• RunUnit myRUBean = new RunUnit("MyApplication", RunUnitStartupOptions.UseManagementBean);
• mbeans=true in cobconfig.properties. in the jar file, or in the class folder
• -Dcom.sun.management.jmxremote
• JMX to Docker and AWS
• AWS monitor in seconds
• CTF Emmiter
