Step 5: Configure the cluster.properties File on Each Cluster Member
Install Oracle Enterprise Repository into a Clustered Environment 5-7
Variables cachesyncurl
The value of the cachesyncurl in the cluster.properties file, which references the same URL as the individual nodes instance with the path of cachesync appended. Most
cluster configurations have a proxy server load-balancing each node within the clustered server.
Example: Node1: cachesyncurl=http:node1.oracle.com:7101oer
Node2: cachesyncurl=http:node1.oracle.com:7101oer It is also possible to validate the clustering installation by viewing the clustering
diagnostic page from the Oracle Enterprise Repository Diagnostics screen. Click Cluster Info on the Diagnostics screen to view the Cluster Diagnostic page. This page
lists information about all servers registered in the cluster, as well as information about inter-server communications.
Oracle HTTP Server Config File If Oracle HTTP Server is used to route from the load balancer to the nodes, the HTTP
Server Config httpd.conf file should include two entries: oer and oer-web. A sample httpd.conf file is shown below:
VirtualHost 10.0.0.1:80 ServerName 10.0.0.1:80
IfModule mod_weblogic.c SecureProxy OFF
TrustedCAFile usrlocalapache2ca.pem RequireSSLHostMatch false
Debug ERR DebugConfigInfo ON
ErrorPage error.html WLLogFile logsworker_matchproxy.log
WLTempDir tmp KeepAliveEnabled ON
KeepAliveSecs 15 HungServerRecoverSecs 30
MaxSkipTime 10 ConnectRetrySecs 5
IfModule Location console
SetHandler weblogic-handler WebLogicCluster 10.0.0.2:7001
Location Location oer_fa_cluster
SetHandler weblogic-handler WebLogicCluster 10.0.0.3:7101,10.0.0.4:7101
Location Location oer_fa_cluster-web
SetHandler weblogic-handler WebLogicCluster 10.0.0.3:7101,10.0.0.4:7101
Location VirtualHost
In this example, host 10.0.0.1 is the HTTP server proxying for the cluster machines, host 10.0.0.2 is the Admin Server, hosts 10.0.0.3 and 10.0.0.4 are the Oracle Enterprise
Repository managed servers.
