Ensure you have the correct JES2 SHASMIG library

To Display the modules linked with HASMFMTM, issue the following IPCS command:

```
IP VERBX HASMFMTM 'JES2,999'
```

to obtain a display shown in the following example:

*** JES2 IPCS Install/Service Information *** 

JES2 FMID = HJE7720 
JES2 release = z/OS 1.7 
JES2 product level = 36 
JES2 IPCS formatter level = 0

Ensure JES2 FMID in display matches JES2 FMID in the dump you're diagnosing.

Ensure JES2 service level in the dump you're diagnosing is within the usable range shown in the display. See Using IPCS panels to analyze JES2 data in a dump to determine the JES2 FMID and service level.

Note: The IPCS service level for a given JES2 release is set in the &J2_IPCS_LEVEL assembly time variable. &J2_IPCS_LEVEL is initially zero for each release and increases with changes to either the JES2 control block mappings, data structures, or IPCS formatters that are changed significantly in the service stream. See "Determining the JES2 release level" z/OS JES2 Installation Exits.
