DSXchange

What is the value of your PWD environment variable. Is your db2nodes.cfg file correct?

Search DSXchange for a server version of the IsValid() function. Adapt as required.

If you do not wish to use the "Reject" capability, then you need to construct a constraint expression is the logical inverse of all other output links' constraint expressions, as you have noted.

No, but it's likely to be the easiest. If "they" don't want to use AT, they are almost certain not to want to use a tool like Samba to mount the disks of one operating system on the other. But it's do-able, in which case DataStage could read from the one and write to the other.

Clients DO have a scheduler. Every operating system has a scheduler. In UNIX it's cron or at and in Windows it's AT.

You can create a named message handler to handle as many message IDs as you like.

Be very careful, though. Suppressing messages may lead to vital information being lost. Prefer to demote them to informational.

If by "ASCL" you mean DataStage then yes. But there's no point. In DataStage you would use an FTP stage; you don't need DataStage in the mix to do this.

Not my preferred approach, as you have differing numbers of space characters in the names.

We don't do "urgent" here. DSXchange is an all-volunteer site whose members post as and when they can, nor are they obliged to do so. If you want urgent help sign up with your official support provider for premium service and learn just how expensive "urgent" can be. You don't n...

If this is a parallel job (as marked) then "blank" is not a legal value. Parallel jobs strictly enforce data type compliance.

The dsjob command can run any kind of job (server, parallel or sequence job).

(Mainframe jobs are run on a mainframe.)

What is different (possibly in the data) between when the inserts are successful and when they are not? Are there any other warnings (for example database not available) also logged?

No. They just have a head start. As parallel routines are developed, whether by the vendor or otherwise, the range of functionality in parallel jobs will catch up, and probably exceed, that available in server jobs. Very few developers, unless they have a background in UniVerse programming, could ha...

What is fd 9 on your system?

Do your formatting (maybe in stage variables) before invoking IsValid().
