Open Deploy to multiple targets

deeps79

Hi,

We need to deploy same content to two different servers under the same docroot.However getting error while deploying to both the servers using two noderefs in the replication farm element.The deployment runs fine on singe server
Here the configuration file :-



<?xml version="1.0" encoding="ISO-8859-1" ?>
<deploymentConfiguration>
<logRules maxBytes="32Mb" level="verbose">
</logRules>

<localNode host="atlstpa3.nextel.com" />

<replicationFarmSet>
<replicationFarm name="PRODUCTION_FARM" quorum="">
<nodeRef useNode="production_tnb2" />

<nodeRef useNode="production_tnb3" />
</replicationFarm>
</replicationFarmSet>

<definition name="ED_DEP_PROD">
<source>
<sourceFilesystem area="$currEdition^" filelist="">
<pathSpecification>
<path name="." />

<filters>
<excludePattern regex="\.dcr$" />
</filters>
</pathSpecification>
</sourceFilesystem>
</source>

<target useReplicationFarm="PRODUCTION_FARM">
<targetFilesystem area="/app/nol4/htdocs" />
</target>
</definition>

<deployment transactional="yes">
<execDeploymentTask useDefinition="ED_DEP_PROD">
<deployNRun>
<dnrDeployment location="source" when="before" state="success">
<script cmd="/opt/appl/cms/perl/ddsync.ipl temp dump full $currEdition^ " async="no" />
</dnrDeployment>

<dnrDeployment location="source" when="after" state="success">
<script cmd="/opt/appl/cms/perl/ddsync.ipl temp load full" async="no" />
</dnrDeployment>
</deployNRun>
</execDeploymentTask>
</deployment>
</deploymentConfiguration>


Have I configured correctly or is there anything wrong ?


TIA

It might help if you explained or showed the errors that you were getting - however - I think I may know what the problem is - and if so - it's because of your DNR's and the only way to fix it that I know of is to replicate most of the contents of your config file (as shown below). I posted about this not too long ago - the problem is that you are attempting to run a DataDeploy synchronization script from your Base Server / TeamSite server to a single database - but when you do a fan-out deployment like this with a single definition you are, in effect, running the same synchronization twice (once for each node in the farm) and any time you are adding new content - both synchronizations will attempt to perform an INSERT operation - the first one will work, the second one will fail because it should now be an UPDATE rather than INSERT because the record now exists.

The solution is to replicate the contents of your deployment configuration so that the DNR scripts are only associated with a replication farm with one node and all other nodes go into a second replication farm:

</replicationFarm>
<replicationFarm name="PRODUCTION_FARM_2" quorum="">
<nodeRef useNode="production_tnb3" />
<!-- Add any other target nodes to *this* farm -->
</replicationFarm>
</replicationFarmSet>

</dnrDeployment>
</deployNRun>
</execDeploymentTask>
<execDeploymentTask useDefinition="ED_DEP_PROD_2"/>
<!-- No DNR script run for the "copy" -->
</deployment>
</deploymentConfiguration>

hope that helps.
