Managing nodes automatically in a System Management Application cluster
You can now enable Auto Node Discovery instead of using the System Management Application (SMA) to manually manage nodes in a cluster. Auto Node Discovery configures the IP addresses of the nodes in a cluster, automatically adds new nodes, and updates the cluster node list. This process works for both Pega Cloud and on-premises deployments to facilitate cluster node management and tracking.
Enter the following JVM arguments to enable Auto Node Discovery before starting JVM:
- Modify the setenv.bat file, which is in the <TOMCAT_HOME>/bin directory, by setting the following JVM argument to true:
-DSMAAutoNodeDiscovery=true
- If necessary, you can override the default values for port number, JMX port, user name, and password:
SMAAutoNodeDiscoveryPort=<PRPCport>
SMAAutoNodeDiscoveryJMXPort=<JMXPort>
SMAAutoNodeDiscoveryUserID=<userid>
SMAAutoNodeDiscoveryPassword=<password>
where
<PRPCPort> is the port number where Pega 7 Platform is running. The default port is 8080.
<JMXport> is the JMX port. The default port is 9004.
<userid> is the user ID for JMX authentication.
<password> is the password for JMX authentication.
An example configuration:
-DSMAAutoNodeDiscoveryPort=xxxx -DSMAAutoNodeDiscoveryJMXPort=xxxx -DSMAAutoNodeDiscoveryUserID=xxxx
-DSMAAutoNodeDiscoveryPassword=xxxx
- To verify that Auto Node Discovery is enabled, open <host>:<port>/prsysmgmt in the SMA browser.
