Re: Monitor IFS in real time for FTP put (new files received)

[CRPence <CRPbottle@xxxxxxxxx>]

  What are the /knowns/ for the use of the FTP PUT subcommand that will 
be issued.  For example is the same target directory always used, a file 
name that is the same or that is generated from a known algorithm, only 
one file per connection, etc.?  The more static information that is 
available, the more there exist options to limit polling and ease of 
coding.  The FTP exit programs can be used to establish a reaction to a 
request that is going to occur.  I suggest in the following link that by 
using a notify object [NFYOBJ] of commitment control or an ALCOBJ in the 
exit program, the end of the session can be determined to effect a 
response to the prior requested activity in the session.  There is also 
reference to the use of file monitors with triggered action via the 
Management Central; a trigger action of sending a message is shown, for 
which a break handling program could be established as an active monitor 
in a background job, to act on the received file.

  A directory can be set to have its files journaled.  A process that 
uses the RCVJRNE to establish response to journal entries via an exit 
program [established on that command invocation] can await activity 
without the impact typical of polling.  A process can use the RTVJRNE 
[or QjoRetrieveJournalEntries API] to get the same information, but best 
when coded as reactive to the specific FTP PUT activity rather than 
generically via polling [which given the comment in the quoted text, I 
infer the MONIFS is doing; except possibly against the audit journal.?].
