Error description
WebSphere MQ File Transfer Edition (WMQFTE) transfer of a text file will hang if old .part files exist in the destination directory. An old .part file will have the name <destinationFileName>.part. The symptom of this problem is that the file is actually transferred but the transfer completion message is never published, and so the transfer appears to have hung. Normally .part files are deleted if a transfer failure occurs. However if a recovery is performed, .part files may remain. WMQFTE attempts to clean up these .part files when a transfer completes. For transfers of text files, a hang will occur when the delete is attempted.
Local fix
Manually remove any .part files before attempting a new transfer. This can cause problems if the incorrect .part file is removed. If in doubt please contact IBM Service or apply maintenance that includes this APAR.
Problem summary
The hang was caused by the agent waiting for a lock to delete the old .part file. However the lock required was for the the same channel that had already been locked and so the thread hangs waiting to acquire the lock. USERS AFFECTED: All PLATFORMS AFFECTED: All
Problem conclusion
This APAR resolves the hang by checking the channel before attempting to lock the file. If the lock is already acquired, then the thread does not attempt to lock it again.
