Re: [staf-users] How to implement STAF Queue?

[David B. <bd...@us...>]

There are a couple different ways to do this.

One way would be to have a STAX job that simply calls the 2 sub-jobs 
within a <sequence>.  So, if you had C:/test1.xml and C:/test2.xml, and 
you want to execute C:/test1.xml, and when it completes, execute 
C:/test2.xml, you could have a STAX job like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE stax SYSTEM "stax.dtd">

<stax>

  <defaultcall function="main"/>

  <function name="main">

    <sequence>

        <job>
          <job-file>'C:/test1.xml'</job-file>
        </job>

        <job>
          <job-file>'C:/test2.xml'</job-file>
        </job>

    </sequence>

  </function>

</stax>

Another way to do this would be to use EventManager to chain the execution 
of your STAX jobs.  So, you could register with EventManager to have 
C:/test2.xml executed when a particular Event type/subtype is generated 
(in this example I will use type "A" and subtype "B"):

staf local eventmanager register machine local service stax request 
"execute file C:/test2.xml" type A subtype B

Then, in C:/test1.xml, at the end of its execution, you could have a 
<stafcmd> to generate this event:

<stafcmd>
  <location>'local'</location>
  <service>'event'</service>
  <request>'generate type A subtype B'</request>
</stafcmd>

This will cause EventManager to start executing (via STAX) C:/test2.xml.

I hope this helps.
