Re: schedulers [847] [848] [849]

Hi CÚsar.
I can understand your concerns. And you're right on some of them... it may
seem confusing... things like the task_id and seq_id should be better
explained... But in short that's two parameters that all tasks functions
should receive.
They identify the task and the "run id".
I'll promote my blog... check this article:

http://informix-technology.blogspot.pt/2010/08/oat-monitor-dbspace-usage-monitorizacao.html

I think you may find it very useful because it contains an example of how
to build a task.

In any case, don't worry too much about what you don't understand... things
like the job runner, autoreg etc will not harm you.

Hmmm... and although I'm going to repeat myself, don't skip the March 26
webcast... you'll probably learn a few more things
about OAT that you may like...
I'm sure you'll still complain. But you'll have more things to complain :)

P.S.: I think you have coding abilities... One of the nicest things about
OAT is that it's very easy to extend... I wish I had more time to
create/publish tasks and plugins for OAT...
Regards
