Portal 7.0 Cluster

Question

Hello,
Has anyone successfully deployed a Portal 7.0 Cluster?
I cannot configure the datasync web application properly to synchronize portal data across all nodes of a cluster.
The Portal 7 documentation does not describe how this should be done and the Portal 4 documentation seems obsolete.
Any help would be greatly appreciated.
Many thanks,
Paul

Paul,
Yes, I have... :-)
Seriously: we made some enhancements to DataSync for 7.0 so that it now
supports a new "server discover" option - the documentation is lagging
behind I am sad to say, so I will try to help you as much as I can here.
In essence if you create a domain using the config wizard and leave all the
default alone DataSync should automatically discover the other machines in
your domain running the same instance of your application and create the
proxies. It is no longer neccessay to edit at Servlet context params or
deploy seperate instances of the DataSync WebApp to the managed nodes and
the admin node.
Note that the 4.0 way of manually creating proxies still works however, and
allows you to add explicit proxies to machines that may be outside your WLS
domain.
For example: if I have three machines Admin, M1 and M2 (where Admin is the
WLS admin machine) and the same application deployed on all three machines
then server discovery should be able to find the instances of the
DataSyncServlet on M1 and M2.
If the URL on the Admin is http://admin:7501/myApp/DataSyncServlet
then it will attempt to contact:
http://m1:7501/myApp/DataSyncServlet and
http://m2:7501/myApp/DataSyncServlet
This requires that your entry point into your cluster is your WLS admin
machine (this will be auto-configured for read/write JDBC persistence on the
Master DataRepository and will perform server discovery). The managed
machines will use read-only JDBC persistence and will not run server
discovery. The persistence defaults can be overriden using System properties
while server discovery can be disabled by setting a DataSyncServlet context
property.
Please let me know if you have any more questions.
Sincerely,
Daniel Selman
