Hi,
I have been having trouble starting the config manager on my window's machine. I go to a command prompt and start the config manager using mqsistart configmgr as usual, and I get the usual message:
BIP8096I: Successful command initiation.....
BUT...when I check in the Windows event viewer, I see the following two error messages:
------------------------------------------------------------
( ConfigMgr ) Unexpected exception in the Configuration Manager DBManager class constructor method; exception text: 'java.lang.ClassNotFoundException: COM.ibm.db2.jdbc.app.DB2Driver', 'COM.ibm.db2.jdbc.app.DB2Driver'.
While attempting a database operation on the configuration repository, an exception was caught by the Configuration Manager DBManager class constructor method. The database operation did not complete successfully. The exception text is: java.lang.ClassNotFoundException: COM.ibm.db2.jdbc.app.DB2Driver, COM.ibm.db2.jdbc.app.DB2Driver.
The exception text may indicate that the DB2 JDBC Driver could be found; check that the system CLASSPATH variable contains access to the DB2 runtime classes. If the DB2 classes are present in the CLASSPATH or if the exception text indicates a different problem, please contact your IBM support center.
----------------------------------------------------------
( ConfigMgr ) The Configuration Manager is not available for use.
A problem has been encountered while trying to start the Configuration Manager. The problem is not expected to be transient.
Stop the Configuration Manager using the mqsistop command. Look at previous error messages for the Configuration Manager in the event log. Determine and correct the cause of the problem before attempting to start the Configuration Manager again. If the problem persists contact your IBM support center.
------------------------------------------------------------
The config manager used to work, and I don't think I made any changes to DB2 or the CLASSPATH...I checked that the DB2 runtime classes are in the CLASSPATH, and it appears that they are...any suggestions of what's going on here?
A little info about what we're running:
--> WBIMB 5.0 (I downloaded latest service for toolkit recently -- fixPack 5), brokers are on z/OS and are also at FixPack 05, but seeing as how I can't get the config manager to start, I don't think it matters where the brokers are
--> Windows 2000 Service Pack 4
--> DB2:
============================================================
About DB2 Administration Tools Environment
============================================================
DB2 administration tools level:
Product identifier SQL08020
Level identifier 03010106
Level DB2 v8.1.7.664
Build level s040914
PTF WR21342
============================================================
Java development kit (JDK):

Please help, I need to deploy new message flows!
Thanks,

I know you said that you hadn't made any changes in this area, but all the signs point to missing DB2 client classes on the CLASSPATH 
Check that all the DB2 zips are there on the classpath and that they can be loaded and read.

Hi,
I did double, and then triple check that the path of the java class mentioned in the error is in the CLASSPATH and Classpath environment vars on my Windows machine
( i.e. C:\Program Files\IBM\SQLLIB\java\COM\ibm\db2\jdbc\app is in CLASSPATH and Classpath)
Is there a list somewhere of which DB2 zips should be in the CLASSPATH?
And how can I check that they can be loaded and read?
The strange part is that the configuration manager used to work, and then one day I logged into the machine, and it didn't. However, other people use this machine too, so there is a small chance that someone made some sort of software change...though I can't figure out what.
What kinds of changes (DB2 service? MQ service? Windows updates?) could cause this config mgr error?
THanks!

On windows, ALWAYS use shortpaths in classpaths.
Secondly, make sure that the classpath is *correct*, and that the classes are there.
Also, try moving the DB2 entries to the front of the classpath.

Sorry for the stupid question, but what do you mean by short paths? Can you give me an example?
Thanks!

In windows, you can have LONG names like:
| Code: |
C:\>dir doc*
Volume in drive C is Local Disk
Volume Serial Number is 74A3-8E68
Directory of C:\
05/05/2005 12:26 PM <DIR> Documents and Settings
|
And windows has a "short name" (left over from DOS days):
| Code: |
C:\>dir /x doc*
Volume in drive C is Local Disk
Volume Serial Number is 74A3-8E68
Directory of C:\
05/05/2005 12:26 PM <DIR> DOCUME~1 Documents and Settings
|
DOCUME~1 is the "short name"

Ok, I have been using short paths, and I checked that the directory that the .zip file for the DB2 class is indeed at the front of my CLASSPATH.
I am at a loss for what to do next...any suggestions?
Thanks,

Which user is that for??? Is that the same user that run's configmgr? If so, the problem is the "user classpath"
(me thinks the user classpath needs at least: C:\PROGRA~1\IBM\SQLLIB\java\db2java.zip)
