Startup and heartbeats

Regarding heartbeats

Hi,

I have a loopback driver, which is supposed to execute something at the publisher channels heartbeat intervals.
The issue that I am having, is that the heartbeat first time is seen once the interval is up (currently after 120 minutes).

I would very much like the driver to do the first processing right after the driver has started.

I tried to generate a status event in the driver startup policy.

It seems to be swallowed before it hits the itp.
Can someone tell me the correct approach?

A convenientt level 3 trace (of the disappearing status event) is here:



LB-NXR01 PT:Applying policy: %+C%14CAdd Status%-C.
LB-NXR01 PT:  Applying to status #1.
LB-NXR01 PT:    Evaluating selection criteria for rule 'Add Status Event'.

I'm pretty sure that's by design. Startup is intended to initialize things internal to the driver config (driver scope variables, etc.) that other policies are going to need. I don't think it's intended that anything done in Startup is going to be seen by the Subscriber or Publisher channel policies.

Thank you.
Does anyone have an idea about an approach to start with something "heartbeat" like?

The reason for asking this is that I figured I could use the initital query

<nds dtdversion="4.0" ndsversion="8.x">
  <source>
    <product edition="Advanced" version="4.5.5.0">DirXML</product>
    <contact>NetIQ Corporation</contact>
  </source>
  <input>
    <query event-id="query-driver-ident" scope="entry">
      <search-class class-name="__driver_identification_class__"/>
      <read-attr/>
    </query>
  </input>
</nds>


And just put extra events on that.
Like this

<nds dtdversion="4.0">
  <source>
    <product instance="LB-NEXUSRoles01" version="4.5.5.0">DirXML Loopback Driver</product>
    <contact>NetIQ Corporation</contact>
  </source>
  <input>
    <query event-id="loopback-driver-capabilities-query">
      <search-class class-name="__driver_identification_class__"/>
    </query>
    <add class-name="NEXUSRole" src-dn="691" src-entry-id="691" when="after">
      <association>691</association>
      <add-attr attr-name="id">
        <value>691</value>
      </add-attr>
      <add-attr attr-name="name">
        <value>Dommedagsprofet</value>
      </add-attr>
      <add-attr attr-name="_organisationId">
        <value>3</value>
      </add-attr>
      <add-attr attr-name="active">
        <value>true</value>
      </add-attr>
    </add>
    <add class-name="NEXUSRole" src-dn="2064" src-entry-id="2064" when="after">
      <association>2064</association>
      <add-attr attr-name="id">
        <value>2064</value>
      </add-attr>
      <add-attr attr-name="name">
        <value>Numismatiker</value>
      </add-attr>
      <add-attr attr-name="_organisationId">
        <value>3</value>
      </add-attr>
      <add-attr attr-name="active">
        <value>true</value>
      </add-attr>
    </add>
  </input>
</nds>


The issue that I am having with this approach is that once we are through the SMP and into the SMP, what I see is a "-9182 Unsupported operation" error. This unsupported operation does not occur, of I do this in a status event (heartbeat).

  </output>
</nds>


So my "real" question is, how do I "fire" a heartbeat like event, when the driver starts, so that I can begin processing right away, instead of waiting for the first heartbeat?
Or is there anything else I can do to get the driver to process right away (on the publisher)

Re: Startup and heartbeats

Maybe set your heartbeat timer lower, so it happens sooner. Then manage the times yourself, see Lothar's notify driver for examples.
