SVCDUMP DOWNLOAD

The automated operations tool can issue this command. Additional control and status information is contained in control registers and permanently assigned storage locations. These dumps must be requested at the same time. Use the cursor point-and-shoot feature and press Enter at the Short, Long, or Extended fields to display the alternate types and formats. You cannot import SYS1.

Automatic import requires the MVS post-dump exit.

Obtaining an SVC dump

It contains valuable information about the dump and the error that caused the dump. If the instruction is a bit address, the high-order byte will be set to low values. Make sure you also specify a dataset naming pattern for the dump copy datasets. Message GIMW is normal for the apply and can be ignored. For this process to occur, you must do the followin g:. Specifying a summary dump also provides a means of dumping many predefined data areas simply by specifying one option.

Obtaining an SVC dump

The CPU has an svcdumo capability, which permits the CPU to switch rapidly to another program in response to exceptional conditions and external stimuli. An SVC dump provides a representation of the virtual storage for the system when an error occurs.

Consult with the MVS system programmer at your site if you need more information. Addresses displayed on this screen are assumed to be from the address space owning SDWA.

Be sure to add the name in the svcudmp in which you want the module to execute. They provide additional information about the region dump: DUMPxx dataset, then the copy is skipped and only automatic import processing applies. The viewing server then starts the automatic import process. A current paperclip table is maintained for each user accessing a given dump.

This screen shows the interpretation based on one of the following types and formats:. This screen displays storage in disassembled format.

Control is returned to DUMPSRV at the end of each post-dump exit and passed to the n ext module in the list unless overridden by processing options. In a synchronous SVC dump, the summary dump data is captured last. Address Address of the 16 bytes displayed on the line. When it has finished processing the interruption, the interrupting program can reload the old PSW, making it again the current PSW, so that the interrupted program can continue.

Typically, a system component requests the dump from a recovery routine when an unexpected error occurs. The paperclip function provides an automatic and convenient method for you to keep track of your navigation through the memory display.

Analyzing an SVC dump

Figure shows the second page. The following individuals are required to perform the tasks described in this chapter:.

SVC dump capture profiles are described in Task Word3 Bytes 8 — B of the 16 or 32 bytes. Interpreted display of the 16 or 32 bytes. This field contains the Program Status Word at the time of the interrupt.

DUMPxx datasets, copied, automatically imported and svcdkmp zed.

When the chain command is ssvcdump, you are placed on the first paperclip entry for the first entry of the chain. The following rules apply: Using the options might not be sufficient to eliminate the problems that are associated with the restricted auxiliary paging storage.
