Monitoring IFS directory for file creation

["JK" <johnking@xxxxxxx>]

Hello all,

 We need to automatically execute a job whenever files are created in a
particular IFS directory. The process needs to work no matter how the files
arrive: via FTP, drag-n-drop from Windows Explorer or other processes yet to
be invented. I could write a sleeper program to monitor the directory every
'x' minutes, but would rather take advantage of a system function if
possible.

 This appears to be do-able by journaling the IFS directory. The archives
are full of examples of doing this for DB2 files, but I want to make sure
this is viable for IFS directories before committing to management. Or maybe
there is a simpler way? Would someone be kind enough to critique this and/or
steer me in the right direction? I think I need to:

1) Create a journal and receiver.
2) Associate the IFS directory with that journal.
3) Submit a QBATCH job that uses RCVJRNE to watch the journal. 
4) The QBATCH job wakes when an entry appears in the journal. If it
determines that a 'file close' action occurred it will submit a job to
process and remove the IFS file.
5) QBATCH program goes back to sleep again.

 I've completed steps 1) and 2) and manually added files to the monitored
directory. Sure 'nuff, the system creates multitudes of journal entries. It
appears the 'CS - IFS object closed' is the one we want to watch.

Questions: 
1) Is OpsNav the only way to manage IFS journaling? I don't always have a
fully-loaded PC next to me and a green-screen command would be a nice
fallback.
2) Using drag-n-drop from WinExp creates 50+ journal entries for each file
created: commitment control, attribute changes, stuff I couldn't care less
about. That seems wasteful, plus I'm confused about exactly which entry
indicates that the file is closed and is safe to process. Can someone
enlighten me?
3) Does a program using RCVJRNE behave similarly to 'QRCVDTAQ'? That is,
does it wait patiently until an entry appears or does it require something
different?
4) What techniques should be used to ensure that the QBATCH program is
running and how to restart it without re-processing existing entries? A
utility named 'DspAudLog' by Mr. Oguine published by iSeries in June 2000
records the last-used journal sequence number in a data area. Is this still
the best technique?
5) What else have I missed?

Many thanks, JK
