This chapter covers some aspects of troubleshooting problems with running JCL applications in an MTO-enabled enterprise server.
Problem diagnosis on a JCL-enabled enterprise server is very similar to problem diagnosis on an enterprise server running Web services or EJB-type services, as described in the chapter Troubleshooting in the Enterprise Server Configuration and Administration Guide.
If you are experiencing problems with the catalog, Micro Focus Product Support might ask you for a catalog trace. The trace shows all the I/O operations on the catalog. To obtain a catalog trace:
[ES-Environment] TEMP=/home/traceES MVSCATIO.TRACE=ON
The text ES-Environment is case sensitive.
If you get MVSJOBNO I/O error 42, delete the file mvsjobds.dat, which you will find in the same directory as your catalog, and then try the failed operation again.
