Running on Windows 2000, MQ version 6.0.0
All has been fine on this machine. However yesterday the MQ Explorer stopping working. I believe it was up and running and someone killed the eclipse and javaw processes, but not sure. Anyway, now it won't start back up.
The error is:
Unable to read workbench state. workbench UI layout will be rest
If you accept that, you get a blank eclipse. If you then select the MQ Explorer perspective, you get:
problems opening perspective
com.ibm.mq.explorer.ui.internal.perspective.mqperspective
You can open other perspectives, i.e. Java, but not the explorer one.
I tried starting the explorer with strmqcfg -c to clean up the cache, but that didn't do anything. With the broker workbench you can delete the .metadata directory and that will help some issues, but, couldn't find such a directory with the mq explorer.
any ideas on how to "refresh" the perspective? I could copy in new plugin's/features, but that seemed a little extreme to do all of them. |

Looks like something has gone well and truely wrong there.
A drastic fix could be to remove your workspace (as you suggested). This will lose all your queue manager connection information but might solve the problem.
The MQ Explorer workspace is stored by default under:
| Code: |
C:\Documents and Settings\<USER>\Application Data\IBM\MQ Explorer\.metadata
|
where <USER> is the appropriate user directory.
At the same time you could try deleteing some of the directories under the eclipse configuration, this will force eclipse to completely rebuild its view of the world - similar to the first time that eclipse is run. If you had 6.0.1.0 or later then this could be achieved using strmqcfg -i
To do this manually delete the following directories (or equivalent on your install)
| Code: |
C:\Program Files\IBM\Eclipse SDK30\eclipse\configuration\org.eclipse.core.runtime
C:\Program Files\IBM\Eclipse SDK30\eclipse\configuration\org.eclipse.osgi
C:\Program Files\IBM\Eclipse SDK30\eclipse\configuration\org.eclipse.update

By deleteing the workspace (thanks, I forgot that under 6 MQ and WMB moved their default location to under the doc & settings folder) and the 3 subdirectories you mentioned, as well as the config file and one additional subdirectory that was in the
C:\Program Files\IBM\Eclipse SDK30\eclipse\configuration\
subdirectory, I was able to get eclipse to start fresh, and now I have a clean eclipse workspace. However, I still have the problem with the mq perspective, it can't open it. Is there a specific plugin/feature or set of them that I could copy from a clean machine and put in place of the corrupted ones? |

If you have a clean install somewhere, then copy the entire set of features and plugins under c:\program files\IBM\WebSphere MQ\eclipse\.
Then make sure that the contents of the three files in c:\program files\IBM\Eclipse SDK\links are correctly pointing to c:\Program Files\IBM\WebSphere MQ\

I copied over all the features and plugin's, and, still have the problem with the mq explorer perspective that appears to be corrupted.
Does anyone know where the
com.ibm.mq.explorer.ui.internal.perspective.mqperspective
is located? |

Did you clear out the workspace and configuration information after replacing the plug-ins? It could be that running some corrupted plugins then contaminated the workspace again.
The other thing to check would be if there are any mq FFST's being produced in the usual place. These might give more of a clue as to what is going wrong here.
To answer your question on the perspective, it is provided by one of the plugins that Jeff mentioned which are located under c:\program files\IBM\WebSphere MQ\eclipse\ but there isn't anything in those directories that should need changing.

| I cleared out the workspace and config information, replaced the features and plugin's, and still got the same error with the perspective. I have a clean Eclipse, but not the explorer. I think I'm resigned to having to reinstall WebSphere MQ. Have to say, it's a little excessive though. |
