File Listener configured on multi node picking same file and processing.
File Listener was configured on multi node(configured around 12 nodes) and looking for a specific format of a file. When File received Listener on one node picked and after few seconds again listener on different node picked up the same file and trying to process it. In File listener rule, process tab "Lock listener's temporary file" check box ha been checked-in.
Do you see any specific reason why Listener on node 2 is trying to process same file which is already picked and processed by Listener on node 1? we see occurrence of this issue very minimal.
Yes. i can see few seconds time between node #1 and node #2 pickup. As per PDN i can see below definition of "Ignore duplicate file names". Do you think by enabling this resolve this issue as both nodes are picking the same file within fraction of seconds. We do have a logic make the file as duplicate form code level but we are getting unnecessary alerts and we might miss original alert when we really receive duplicate file from source system. Here my observation is Node #1 picked the file and file is under processing. As File processing was not completed file is still available in source location. Then somehow Node #2 picks same file which might causing this issue. is this correct assumption?
Select to prevent the processing of a second or later file that has the same name as a previously processed file.
If selected, the system searches the Log-Service-File class for past instances of processing by any listener containing the current file name. If a match is found, the system:
Bypasses normal processing of the file
Copies the duplicate input file to the work directory
