Hi,
We have WMQI broker created on OS/390. When no configuration is deployed yet, and the broker is started it starts without any problem. But when a initial deployment is done from the configuration manager (Only Topology no message flows yet), there seems to be a problem.
The broker recognizes the Broker UID passed to it from the config manager, and also a default execution group is deployed on it and it starts this execution group. But immediately it starts giving the message in the os/390 system logs that the broker has detected that execution group default has shut down, it tries to start again and the same cycle repeats.
It also gives a system dump at the home directory of the userid (started task of the broker). These dumps are around 60MB to 130MB. The JCL BIPJRSTC to format the dump fails bcz it can not open these dump files. Even copying these dump files from Unix file to a Data Set also fails.
Is this a known problem? Any fix pacs available for this? |

The most common problem which causes dumps is some missing prereq.
- Did you installed all necessary PTFs ( check part "5.2 Target System Requirements" of the "Program Directory for WebSphere MQ Integrator for z/OS" ?
- Do you use "New Era of Networking" nodes ? If not ( i.e. Neon part is not customized ), you have to remove /local/wmqi/lil/imbdfneo.lil ( if installed ) to avoid Neon initialization.
BTW: Check "Chapter 12. WebSphere MQ Integrator dumps" of the "WebSphere MQ Integrator Problem Determination Guide" for general information about WMQI dumps. You can format and read the dump using IPCS facility. |

Hi,
Now the prblem is solved.
Actually after applying CSD2 the broker stopped giving dumps. But still the default execution group would keep failing, but this time the system log clearly mentioned "could not load /usr/lpp/wmqi/lil/imbdfneo.lil".. So as Bolek mentioned we renamed this imbdfneo.lil and re-started the broker. This solved the problem. Thanks Bolek.
But I wonder if this is the permanent solution, because even though we are not using any NEON related functionality at present within the broker what if we have to use it in future? |

If I'm not mistaken, WMQI 2.1 on z/OS includes 2 installation packages:
WMQI base and Neon nodes.
If you don't need New Era of Networking nodes, you don't need to install Neon package ( which includes imbdfneo.lil ). If you need Neon, you have to install Neon package AND perform Neon customization ( i.e. specify NNSY PATH/LIBPATH/Databases/etc ). Redbook specified in the Zpat's message describes Neon configuration. |
