Using IPCS panels to analyze JES2 data in a dump

Your Time Sharing Options/Extensions (TSO/E) logon procedure should include the data sets that contain the JES2 panels, models, and find routines. If the logon procedure does not contain these data sets, you can create a TSO/E CLIST or a Restructured Extended Executor Language (REXX) exec to concatenate the needed data sets with other data sets you need for ISPF. See z/OS MVS IPCS User's Guide and z/OS MVS IPCS Customization for information about allocating these libraries.

From the JES2 Component Data Analysis menu, you can select the information you want to display from the dump. You can request dump information based on job and job output control blocks, devices, processors, subtasks, network control blocks, and MAS members. Most of the options will place you at another panel to request more information. All of the panels have help screens to aid you in data entry, and the details of those panels will not be repeated here.

Use the JES2 base display for every dump containing JES2 data, including dumps of jobs executing under JES2 control. This display includes information about the JES2 subsystem and reports numerous exception conditions.

The following example JES2 base display reports a common problem where the JES2 IPCS support doesn't match the JES2 in the dump:
