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

Thank you both for your replies. I went ahead and "cheated" because it had 
to be finished today.  I had the ILE job submit a CL which created a new 
job and then there was no issue copying the file into QDLS and sending it 
out via SNDDST. 

I know that's bad programming, but we have another project just like this 
one coming up so I can use some of it's allocated time to change over to 
either JavaMail, MMAIL, or SNDM.  There was just no way I was going to get 
it done today.  =)

Unfortunately, I spent most of this projects time learning ILE procedures 
and binding, HSSF POI, and free-form coding courtesy of the many, many, 
articles Scott Klement has been kind enough to write.

Thanks Scott!

QDLS is not a thread safe file system which is why you're getting this
error. We use a program called SNDM (you'll need to search for it, I
don't recall the web site) which is pretty easy to use and doesn't
require that you have a mail server running locally. How easy it is to
replace SNDDST with SND depends a little upon what all you're doing with
it.

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.
