Hi Nima,
First take a look at this:
http://xarg.net/tools/cvs/change-set-details?key=22923
There was a problem with the dinamic definition
of util_memoize_flush.
As you mentioned, there are some parameter in ACS Kernel related to clustering.
Lets put an example of this.
I have to instances of Openacs ( both of them using
the same DB. ).
First one in : 10.0.0.45:8801
Sencond one in: 10.0.045:8802
So the configuration for clustering goes like this
CanonicalServer: 10.0.0.45:8801( Primary server in the cluster ).
ClusterAuthorizedIP: 10.0.0.45:8801 10.0.045:8802 ( List of Servers that can issue requests. All Servers listed here will execute the local flush requested from anyother Server in the cluster, take a look at /www/SYSTEM/flush-memoized-statement.tcl and you will get the idea of this parameter).
ClusterEnabledP: 1 ( This enables the cluster)
ClusterPeerIP: 10.0.0.45:8801 10.0.045:8802 ( List of Servers included in the cluster ).
EnableLoggingP: 1 ( Debbuging messages in your log files).
I hope this helps you.
Cheers,
Victor Guerra.
