Debugging a Snapshot file

A process Snapshot file or Snapshot is a disk file that is an image of a process, its data, and its

status at the moment it was saved. Snapshot files are analogous to core files on UNIX systems.

Snapshot files have file code 130. The ability to examine a Snapshot file can be useful when a

process terminates abnormally and you want to determine the circumstances in effect at the time

of the termination.

You cannot execute any commands that would alter the state of the Snapshot, or commands that

would execute a process, such as step or continue. Such commands report an error during Snapshot

analysis.

To debug a NonStop Snapshot file, you must select or create a NonStop Snapshot debug

configuration:

• If you want to reuse an existing NonStop Snapshot debug configuration and do not need to

modify it, in the Debug Configurations dialog, in the configurations list, select the debug

configuration you want use and double-click to launch it.

TIP: If the configurations list contains a large number of debug configurations, find the one

you want to select by filtering the results as described in “Listing and filtering debug

configurations” (page 27).

• To create a new NonStop Snapshot debug configuration, see “Creating a new NonStop

Snapshot debug configuration” (page 24).

• To modify an existing NonStop Snapshot debug configuration, see “Modifying an existing

NonStop Snapshot debug configuration” (page 26).

NOTE: Often you can access wizards, dialogs, and actions using more than one method. For

information about other methods for accessing a wizard or dialog, see the reference topic for that

wizard or dialog.
