If your application calls CEE3DMP, the Language Environment dump is written to the file specified in the FNAME parameter of CEE3DMP (the default is CEEDUMP).
If your application is running under TSO or batch, and a CEEDUMP DD is not specified, Language Environment writes the CEEDUMP to the batch log (SYSOUT=* by default). You can change the SYSOUT class by specifying a CEEDUMP DD, or by setting the environment variable, _CEE_DMPTARG=SYSOUT(x), where x is the preferred SYSOUT class.
If your application is running under z/OS UNIX and is either running in an address space you issued a fork() to, or if it is invoked by one of the exec family of functions, the dump is written to the hierarchical file system (HFS). Language Environment writes the CEEDUMP to one of the following directories in the specified order:
The name of this file changes with each dump and uses the following format:
/path/Fname.Date.Time.Pid
