replace unix file and abap prog triggers

[Former Member]

Hi All,

I had an ABAP program which is scheduled to reads a file at a unix directory.

But instead my program should get triggered when there is a Change to the existing file or a new file comes in in the unix directory.Is there any way to trigger?

Please provide your valuable suggestions , points will be granted for sure.

Thanks

The only way is that the program that creates or modifies files call the ABAP report, eg by raising a sapevt event.

If is it not possibile, you can schedule a script at OS level that periodically checks for new or modified files and calls sapevt if needed.

Suman,

One approach would be to just regularly scan for your config file being modified

(just stat() and check st_mtime in unix) with date and timestamp... How often you want to check is up to you, but I wouldn't think more than once per minute would be necessary, unless you have some need to make changes instantly or something...

Another approach would be to use dnotify/inotify to have the kernel notify you when

the file changes...

Hope this helps

Cheers
