As a stop gap measure, we are using Google's custom search engine service.

Subject: Re: Anybody know a good way to monitor the size of an IFS STMF
There seem to be two pieces: (1) How do you retrieve the size of a stream file? (2) How do you monitor this?
The answer to (2) is pretty much the same as how you would monitor anything else on the i. Maybe set up a recurring job that performs (1) and then gives you a report or alerts you if a threshold is reached, etc.
So how to do (1)? Well, one fairly simple way is to get the output of a Unix-style directory listing using Qshell. You can direct that output to a physical file, if you find it easier to work with it there. For example,
qsh cmd('ls -l /my/ifs/file > /qsys.lib/mylib.lib/myfile.file/mymbr.mbr')
Then, in MYMBR you will have something of the form
-rwxrwxrwx 1 OWNER 0 4323 Dec 3 2014 /my/ifs/file
You can substring that to pull out the size (in this case, 4323 bytes).
It's not as robust as using APIs to work with IFS files "directly", but if you don't already have the wrappers and scaffolding set up to handle the APIs, this is a very straightforward and quick way to get what you need.
