Hi,
I have a complex C/C++ program(s) that is looping in batch mode.
If I cancel with dump(CD), I get a dump but it is worthless. It does not have a stack trace.
The question is how can I get CEEDUMP or IPCS dump so I can get the stack trace. (I know how to get a stack trace from a IPCS dump)
With CD a SYSMDUMP and SYSUDUMP both produce a useless text dump.
I do not get a CEEDUMP.
I can set a slip but not really sure where to set it.
Thanks for any help. |

re: produce a useless text dump
I do not know what a text dump is. But sysmdump should produce a binary file that you can look at with IPCS. Your JCL should have a DD statement for SYSMDUMP output file.
If I were in this situation I would add my own trace control blocks where I would store my own breadcrumb information - the starting and stopping of various routines and the like.
And if the dump does not show your trace information, then also add print statements to your program. |

re: "that is looping in batch mode"
Does that mean it is working successfully in a different mode? Please explain. |

| Maybe a GFT trace or SLIP trap? |

SYSMDUMP gave me a dump in IPCS format that I can use to get a stack trace.
Thanks you. |
