User directed dumps z/OS DFSMSdfp Diagnosis SC23-6863-00 |

In addition to the automatic dumps previously described, you can also optionally specify whether VSAM Record Management dynamic dumping is to occur for specific events identified by a combination of a return code, error (reason) code, problem determination function (PDF or FUNC) code, and component code returned in the request parameter list (RPL) feedback area. (See Return codes from the record-management (request) macros.) You can request a user directed dump (or change the parameters for an existing dump request) with the MODIFY CATALOG,VDUMPON command. You can turn off the dump request with the MODIFY CATALOG,VDUMPOFF command. See z/OS MVS System Commands for a complete description of the MODIFY CATALOG,VDUMPON and MODIFY CATALOG,VDUMPOFF commands. For example:
requests
a dump for any return code 8, error code 20 (exclusive control conflict),
with any PDF code and any component code. z/OS® acknowledges the command
withe following messages:
If a dump is later generated, z/OS will issue a message similar to that generated for an automatic dump. |
