Hi All,

We have MQ 7.5.0.0 where we are trying to configure XA.
The steps followed are

1. Install Oracle 32 bit client on the system
2. Copy the jdbcora11.dll from <install path>/java/lib/jdbc to the exit folder
3. Configured the Resource Manager.
4. Stop the queue manager
5. Start the queue manager

The queue manager does not start.

The errors printed are

AMQ6256: The system could not dynamically load the DLL 'C:\Program Files(X86)\IBM\WebSphere MQ\exits\jdbcora11.dll
Explanation:
The DLL 'C:\Program Files(X86)\IBM\WebSphere MQ\exits\jdbcora11.dll failed to load as it is probably a 64-bit DLL, a 32-bit DLL is required. Note that the MQ tried to find a 32-bit DLL named 'C:\Program Files(X86)\IBM\WebSphere MQ\exits32\jdbcora11.dll',but failed.
ACTION:
Supply the name of a 32-bit DLL

We are sure we have copied jdbcora.dll from <install path>/java/lib/jdbc and placed in exits folder. But still the above error.

Request your help to resolve the above

Regards,
mqusr

And you're sure it's the 32 bit version?

Don't know at MQ 7.5 which version of the jdbcora.dll you get delivered with the product, but there is one at $MQ_INSTALL_PATH/java/lib/jdbc and $MQ_INSTALL_PATH/java/lib64/jdbc...

If those are on your path you don't need to copy it to the exits path now...
And who's to say that they are compiled right for an exit anyways (re-entrant, thread safe and all that...)

What are you trying to do and why do you need the jdbcora.dll in the exit path?

Hi All,

We were able to solve the issue. Our Oracle client was 64bit and not 32 bit, hence the issue.

All worked fine post installation of oracle 32 bit client on the system.

Thanks all for your inputs

Regards,
mqusr
