Re: Can't copy file from root IFS to QDLS



I'm having issues with the HSSF POI.  I can save the file to the root IFS,
but then I can't email it because SNDDST uses QDLS.  The problem is that I
can't move or copy the file because then I get the error: "Operation not
allowed in a job running multiple threads. ".


I suggest retiring QDLS and SNDDST.
The problem is due to the fact that Java is a multi-threaded language. When you run a Java program, it sets a flag saying "this is a multi-threaded job". Once that happens, you can't write data to the old /QDLS filesystem, because that filesystem (which was designed for the S/38 back in the 80's) can't handle multi-threaded access. It would cause the filesystem to be corrupt.
Of course, that's only one of the many flaws in QDLS. It has an awkward security model. It's slow. It's limited to 8.3 filenames. It has severe file size limitations. But, the speed of it is my biggest beef.
Unfortunately, many of IBM's old officevision tools require QDLS. CPYTOPCD, SNDDST, etc. It's too bad, because some of those tools still have value, despite being ancient.
My recommendation is to replace them with modern tools that use modern filesystems. For e-mail, try MMAIL (it's free)

Or SNDM from Uzaemon

Or the MIME utility from JP LaMontre

Or if you'd like to write your own e-mail software, check out the following articles (requires a membership in System iNetwork, but a free ("Associate") membership will work)

I'm sure there are a half dozen other alternatives that I've forgotten.
