Hi All,
I need to get number of files (files count) in particular directory using wmb flows.
Thanks for support

Why?
You certainly don't need it to read every file in that directory.

Hi,
Actually my requirement is need to read all files and write into one file at every day evening.
I have checked batch processing sample code, but in that is file count is hard coded as 3.
but in my situation not known how many files arrival in that particular location.
Thanks |

You still don't need to know how many files you have.
You merely need to know either when to start processing all files or when you have reached the last file.
If you are using the FileRead node, you can use propagate to send messages to the file read node, and some variable to tell if the fileoutput read something.
| Code: |
foundAFile = true
while foundAFile is true:
foundAFile = false
propagate
end |
Then something downstream of the fileread sets foundAFile to true. If that doesn't happen, then the loop ends.

So you tell however decided to take the risk of using out of support software that the risk just failed to come off.
One option (aside from upgrading to a supported version) is to read the files as they arrive with a FileInput node, copy the contents to a database and "in the evening" copy the accumulated contents of the database to the output file.

Does Broker 6.1 support ATOMIC operations in esql? It's not possible to find out, unless one has a copy of 6.1 lying around, because the documentation for 6.1 is no longer available through IBM, at least in a knowledge center format (there might be pdfs).

IIRC Atomic was available in 6.0
