Bradley,

Maybe this will help solve the problem. I found that the descriptor is a Java term and there must be 3 of them open for the default I/O that Java has. When I found this I included a single call that uses a java routine from Scott's HSSF interface and the open was successful. But now there is another problem. It is reading garbage. It is supposed to be an ascii file. When I use WRKLNK, I can put a 5 on the file and it displays no problem. But when the program uses read, the line looks like garbage. The Job's CCSID is 37 and the files attributes say that it is CCSID 37. I have no idea what is going on. I made the change you suggested but the read is still garbage.

Between the descriptor error and this garbage read, I hope someone can come up with an explanation of what is happening.

Thanks,
 
Marvin

Here's what I believe is the problem:

if filehandle <= *zero;

filehandle can be, and probably is zero (since it's the first descriptor you're probably using to open a file). This should be:

if filehandle < *zero;

or

if filehandle < 0;

Here is the error message:

And you're sure it's on open() and not read() or write()?

Do you have a lot of programs that use sockets and/or open IFS files?
Or maybe 3rd party applications? I've seen a lot of issues where
descriptors aren't closed properly and other programs can't open a new
one, or they try to use one that isn't the one it opened.

I asked for a code snippet for a reason... I was curious. If you
could post the return codes and error numbers as well, that would help.

If it's working on devo and not on prod I see two possible issues:

1. OS issue (doubtful)
2. Job isn't properly creating/closing open descriptors (for IFS
and/or sockets).

Of course, another possibility is the code isn't the same.

Bradley,

It worked with no problems on our development box. This problem only
occurred on the Production system.

Can you post your open code? Maybe you defined your file descriptor
incorrectly?

I am having a very strange problem. When I attempt to open an IFS

Can anyone tell me why I am getting this error. We are on 7.1 and
I am using Scott Klement's set up.

Thanks,
