Port Number Conflicts

The common agent container (V2.1) included with Java ES reserves the following port numbers by default:

• JMX port (TCP) = 11162

• SNMP Adaptor port (UDP) = 11161

• SNMP Adaptor port for traps (UDP) = 11162

• Commandstream Adaptor port (TCP) = 11163

• RMI connector port (TCP) = 11164

If you are troubleshooting an installation of Sun Cluster software, the port assignments are different because Sun Cluster software uses a different version of common agent container. In this case, default ports are as follows:

• JMX port (TCP) = 10162

• SNMP Adaptor port (UDP) = 10161

• SNMP Adaptor port for traps (UDP) = 10162

• Commandstream Adaptor port (TCP) = 10163

• RMI connector port (TCP) = 10164

If your installation already reserves any of these port numbers, change the port numbers used by the common agent container as described in the following procedure.

Checking Port Numbering

For further information on the common agent container cacaoadm command, see the cacaoadm man page. If you cannot see this man page at the command line, verify that your MANPATH is set correctly. Refer to Verifying Man Pages .

To Verify Port for Solaris OS

Before You Begin

The path to cacaoadm on Solaris is:

• Common Agent Container V1.1 /opt/SUNWcacao/bin/cacaoadm

• Common Agent Container V2.x /usr/sbin/cacaoadm

1. As root, stop the common agent container management daemon:

   /usr/sbin/cacaoadm stop

2. Change the port number using the following syntax:

   /usr/sbin/cacaoadm set-param param=value

   For example, to change the port occupied by the SNMP Adaptor from the default 11161 to 11165:

   ---

   Note –

   For Sun Cluster software, use previously-specified ports.

   ---

   /usr/sbin/cacaoadm set-param snmp-adaptor-port=11165

3. Restart the common agent container management daemon:

   /usr/sbin/cacaoadm start

To Verify Port For Linux

1. As root, stop the common agent container management daemon:

   /opt/sun/cacao/bin/cacaoadm stop

2. Change the port number using the following syntax:

   /opt/sun/cacao/bin/cacaoadm set-param param=value

   For example, to change the port occupied by the SNMP Adaptor from 11161 to 11165:

   /opt/sun/cacao/bin/cacaoadm set-param snmp-adaptor-port=11165

3. Restart the common agent container management daemon:

   /opt/sun/cacao/bin/cacaoadm start
