RE: trigger on file after remote ftp

Santosh,

Are you sure that your COBOL process has finished with the file when your
second attempt to PUT fails? Perhaps it still has a lock on the member and
that is why FTP cannot write to the file.

Are you sure that your COBOL process is not deleting the member when it
finishes processing it?

You might try using FTP remote command to fire your COBOL process. From the
client, after the PUT, send QUOTE RCMD ccc where ccc is whatever CL command
you want to execute on the AS/400. This is essentially what you were
suggesting in your idea #3, but less work.

My problem:

A file called  FL55AFL comes from the remote machine via FTP.
The command there is

PUT SANTOSH/TRGTEST.TRGTEST               QGPL/FL55AFL.FL55AFL

this works fine everytime i run it and the file gets changed at the local
machine.

Now i have added a trigger on the file FL55AFL for an after/insert.
This trigger will call a CL and a COBOL program. THe cobol program does
some calculations after that.

After this i again ftp from remote nachine with the fol command..
PUT SANTOSH/TRGTEST.TRGTEST               QGPL/FL55AFL.FL55AFL

this results in failure of ftp with the fol error mesg.

 put santosh/trgtest.trgtest  fl55afl
 227 Entering Passive Mode (89,0,0,16,20,78).
 150 Sending file to member FL55AFL in file FL55AFL in library QGPL.
 426-Cannot write to member FL55AFL in file FL55AFL in library QGPL.
 426 Data transfer ended.
  Message . . . . :   426-Cannot write to member FL55AFL in file FL55AFL in
   library QGPL.

Now when i go to the local machine and check the file, it has no members
while before ftp , it had 1 member .

Apparantly, when the ftp was executed , it seems that it deletes the
existing member and creates a new one.
While the member was deleted during ftp , it was not created successfully.

If I remove the trigger, the thing starts working.

My requirement is very simple :
Whenever a particular file comes to my machine, i should be able to run a
program.
For this, i can think of 3 ways :

1, The way i mentioned as above . but i got stuck.
2. Can we monitor the change date and time of a particular file
continously. Whenever it is updated , the required cobol program will run.

3. From the remote system , after the ftp , we  send a message  thru socket
programs which when recieved here will fire the cobol application. This
options is always used in my company and a third party product runs here
just like the MQ Series.

But my contention is why isnt the first option working?
why is the trigger preventing in creation of a member during ftp.

Are there some options to be given in the ftp   command which will make it
happen???

I hope u all go the right picture of my problem,

Santosh.
