check error starting master sequence

[lory]

I have a master sequence with several child sequences. These child sequences run other
child sequences.
How can I check error or warning with a unix shell starting by master sequence?

Thanks!

Build error checking into every sequence. A parent sequence can check it's child processes' exit status. You can use a custom trigger based on exit status, or you can use a Command or Routine activity to capture the status.
It's very difficult to do from the operating system, because you need to be able to determine the pid of the master process then of its children, then of their children and so on, but mainly because the DataStage status is not the same as the exit status of the executing process. The executing process will typically finish with an exit status of zero, even though the job aborted; this is not a UNIX issue; the abort condition is logged and, depending on the argument to DSAttachJob(), propagated to the parent process.

"the abort condition is logged and, depending on the argument to DSAttachJob(), propagated to the parent process...."

Could you explain better?

I'm very new to datastage!

Read the on-line help about DSAttachJob(). Its second argument determines whether, if the controlled job aborts:
(a) the controller aborts
(b) the controller logs a warning but keeps going
(c) the controller keeps going without logging anything

Automatically-generated job control code chooses option (a), while job sequences choose option (c). Inspect the code that is generated by compiling the job sequence, and find an occurrence of DSAttachJob() to see what I mean.
