SPARC: Guidelines for Setting the Communications Port Range for the Oracle UDLM

An application other than the Oracle UDLM on a cluster node might use a range of communications ports that conflicts with the range for the Oracle UDLM. If such a conflict occurs, modify the range of communications ports that the Oracle UDLM uses.

The range of communications ports that the Oracle UDLM uses is determined by the values of the following extension properties of the SUNW.rac_udlm resource type:

• Port. Specifies the communications port number that the Oracle UDLM uses. The first number in the range of communications port numbers that the Oracle UDLM uses is the value of Port.

• Num_ports. Specifies the number of communications ports that the Oracle UDLM uses. The last number in the range of communications port numbers that the Oracle UDLM uses is the sum of the values of Port and Num_ports.

For more information, see SPARC: SUNW.rac_udlm Extension Properties.

Example 4–3 Setting the Communications Port Number for the Oracle UDLM

# clresource set -p port=7000 rac-udlm-rs

This example sets the communications port number that the Oracle UDLM uses to 7000. The following assumptions apply to this example:

• The Oracle UDLM component is represented by an instance of the SUNW.rac_udlm resource type that is named rac-udlm-rs.

• The command in this example is run as part of the procedure for modifying an extension property that is tunable only when disabled. For more information, see How to Modify an Extension Property That Is Tunable Only When a Resource Is Disabled.
