Greetings all,
I have an MQ script for Vugen 9.52 with MQTester 3.30. I have two client machines which are pretty much identical.
Windows XP SP3
IBM Websphere MQ Series version 6
Vugen 9.52
MQtester 3.30
On client machine 1, the script compiles and runs flawlessly. On client machine 2, it bombs out with the following error:
Warning: LoadLibrary failed for extension lrmq_replay_client.dll. System error: The specified module could not be found.
[MsgId: MWAR-10500]
Warning: Extension lrmq_replay_client.dll is not loaded. [MsgId: MWAR-10593]
Error: Thread Context: Call to service of the driver failed, reason - thread context wasn't initialized on this thread. [MsgId: MERR-10176]
Warning: Extension lrmq_replay_client.dll is not loaded. [MsgId: MWAR-10484]
The mdrv.dat file has the correct references to the file as well.
[MQSeries-Client]

AIX_EXT_LIBS=lrmq_replay_client.so
HPUX_EXT_LIBS=lrmq_replay_client.sl

UtilityExt=lrun_api

I've tried repairing/reinstalling MQTester and IBM Websphere MQ. It seems that the DLL is not getting loaded at compile/runtime, but I can't find out why not. Anyone have some advice? |

Does the .dll exist?

Yes. They do.
I'm looking into the CLASSPATH and the PATH right now... |

@bruce2359.
CLASSPATH and PATH look good, but did not help. |

Yes. Both PATH and CLASS PATH. |

on the DEV box or runtime box?
Is the install path for your app different on the runtime box, so that your app could not find the dll?

Oddly, on the working box, the dll is not in the PATH or CLASSPATH. On the non-working box, I added it manually to PATH and CLASSPATH. I only added it because I couldn't figure out why it's NOT finding the damn DLL. I tried also using Process Explorer and Process Monitor on both machines to see if I can find the hook that calls the DLL; no luck.

I'd suspect your environment is not what you think it is.
Log the output of SET before starting your program...

Well, that took some time. Removed VuGen 9.52, remove Load Generator 9.52, removed MQTester 3.30. Renamed the old folder for Load Generator and VuGen. Rebooted a couple of times. Reinstalled all the above software in the following order:
VuGen 9.50 + QFE 9.51 and QFE 9.52 + IE8 patch
Load Generator 9.50 +QFE 9.51 and QFE 9.52
Rebooted a couple of times.
Installed MQTester.
Outputted my two PATH's and did a compare. There are very minor differences in them, specifically indicating some applications that are not installed on the second machine completely unrelated to VuGen / Load Generator (e.g. SSH).
Launched VuGen. Created an MQ Script hit compile.
Guess what?
Warning: LoadLibrary failed for extension lrmq_replay_client.dll. System error: The specified module could not be found.
[MsgId: MWAR-10500]

GAH!!!!!!

Are you per chance missing a step in your compile?
Do you need to pre-compile the libraries before launching the make?
Do you need to configure VuGen once launched for it to find the libraries in question?

Of your three options, I'm thinking there is a potential for:
Do you need to configure VuGen once launched for it to find the libraries in question?
On my prior installs, I didn't have to do something per se. My suspicion is that there is some call that is not being made to grab the DLL. In desperation, I even moved over the entire VuGen install from my working machine. To no avail.
I've done a compare on the two folders (working and non) and there are some differences. I'm not necessarily surprised since a well used install will get peppered with configs/temp files/setting changes etc. But, somewhere there must be a call to the DLL.
I love these problems. Especially when I solve them. But this one is making me not happy. |

I figure in one of the config files for VuGen you have the library path or external library path or default library path etc... You get my drift...

@all,
Greetings all,
Since no one likes a missing solution, here it how I solved it.
While the lrmq_replay_client.dll was being thrown as the error, the issue was actually with a missing DLL as part of the IBM Websphere MQ install: AMQZSAIC.DLL
I modified my installation of Websphere MQ to install "everything" and then the script compiled with no errors.
To find the missing dependency, I used a program called Dependency Walker (http://www.dependencywalker.com/)
I selected the lrmq_replay_client.dll and it threw and error that AMQZSAIC.DLL was missing. Tracked that back to Websphere MQ with Dependency Walker. Done.
Feel much better now.
Thanks for any advice. |
