CEE3DMP callable service

CEE3DMP generates a dump of Language Environment and the member language libraries. Sections of the dump are selectively included, depending on options specified with the options parameter. Output from CEE3DMP is written to the default ddname CEEDUMP, unless you specify the ddname of another file by using the FNAME option of CEE3DMP. The call to CEE3DMP does not cause your application to terminate. For an example of a dump and a description of the Language Environment dump service, see z/OS Language Environment Debugging Guide.

CEE3DMP can be called by your application when you want:

A trace of calls so you can see the order in which applications were called
A dump of storage and control blocks
The status of files to determine if a file is open or closed and to see the buffer contents of the file

If your application runs in a non-fork() address space, the CEEDUMP DD statement specifies the name of the dump file. If your application runs in the z/OS UNIX environment, CEEDUMP DD can contain the PATH= keyword, which specifies the fully qualified z/OS UNIX path and file name.
