Hello.

IIB version 10.0.0.8 on windows.

A single-instance file processing message flow.

We are experiencing an issue with the message flow getting stuck after an I/O error in the FileInput node.

Here is the error from the event viewer:
Quote:
File node "My_File_Input" in message flow "myflow" encountered an I/O exception
"<com.ibm.broker.plugin.MbRecoverableException class:com.ibm.broker.flowgroupfiles.MbFile method:moveTo source:BIPmsgs key:3315>" while reading the file "some-uuid_myfile.xml".


After the error is displayed, the file is left in the mqsitransitin folder,
and no further files are processed by the input node until the broker is restarted.

Reading the description for BIP3315,
does this mean that the broker fails to move the file from mqsitransitin to mqsiarchive ?
(The input node is configured to "add timestamp and move to archive".)

This is not a permissions issue since it only happens occasionally and inconsistently.
It is also not a disk space problem, there is enough space.

Also once this happens, and the flow gets stuck,
we can manually remove the file from mqsitransitin, so its not even locked at this point,
but the flow will not proceed.

What else could be the reason for such behavior ?
Is the broker supposed to retry the file move ?
If it is, what is the retry delay ?

Any help will be welcome.

Many thanks.

I have seen files getting stuck in mqsitransit folder only when IIB node was stopped abrutly as it could not complete the processing.

Something like an anti-virus scan which has the file locked when the broker tries to access it, but has released it by the time you try to move it manually.

No. From a design standpoint, the broker has no reason to assume anything's going to change without human intervention (consider if the permissions were in fact wrong, or the disc was full) so there's no point retrying.

See above.

Change the permissions on the folders IIB uses so only the IIB account can access them and see who complains their application is getting "Access denied".

If no one complains, see what is running with administrator access.

We will check about anti-virus and then try this idea.

Thank you!
