Customizing the contents of the SVC dump

For a specific address space, or for each address space you identify, you can request that the system include or exclude specific storage or ranges of storage. By coding additional parameters, you can request that the system:

Dump certain areas of private or common storage (SDATA parameter with options)
Override default options (SDATA parameter with NODEFS).

Do not specify all SDATA parameters unless you need all storage areas to diagnose the error. If you do not need a particular area, omit the corresponding option or omit the SDATA parameter. Whenever possible, tailor the SVC dump using the storage list parameters, such as LISTD (on SDUMPX only), LIST, LISTA, and STORAGE.

Generally, each installation defines default options for SVC dumps and sets up specific formatters for those dumps. If you override the default options, provide your own interactive problem control system (IPCS) CLIST to format the dump contents.
