Printing dumps

Db2 supports IPCS under z/OS®. It is recommended to use IPCS for versatility to print dumps.

The Db2 dump formatter routine, DSNWDPRD, is invoked by IPCS with:

DB2 VERBEXIT DSNWDMP

The following sample contains JCL for printing and formatting a dump through IPCS. These JCL samples illustrate the appropriate parameters for formatting SVC, stand-alone, and dynamic dumps. The DSNWDMP control statement that is shown in the examples causes the Db2 dump formatter (DSNWDPRD) to be invoked and defines the Db2 control block structures to be formatted.

The JCL included here contains only the DD statements that are recommended for Db2. Your site might choose to include other DD statements as well.

Figure 1. Sample JCL for printing dumps through IPCS in the z/OS environment. The format of the JOB statement is defined by the site.

  //*   For printing stand-alone and dynamic dumps,

  //*   SUBSYS=DB2_subsystem_name'

    CLOSE    ALL
  END
The DSNWDMP statement can be changed to print SVC, stand-alone, or
dynamic dumps.
