Default Port Numbers Reserved by Sun Cluster

Sun Cluster reserves certain port numbers for internal use. These port numbers are stored in the clustername.cdb file. Note the following reserved port numbers when planning your configuration, data services, and applications.

In addition, note that Solaris reserves ports 6000 to 6031 for UNIX Distributed Lock Manager (UDLM). UDLM is used with Oracle Parallel Server configurations.

Table 2-4 Default Ports Reserved by Sun Cluster


Port Number	Reserved For...
5556	Cluster Membership Monitor
5568-5599	VERITAS Volume Manager cluster feature, `vxclust`
5559	VERITAS Volume Manager cluster feature, `vxkmsgd`
5560	VERITAS Volume Manager cluster feature, `vxconfigd`
603	`sm_configd` and `smad` (for TCP and UDP)

Changing these port numbers is not allowed, except in the case of sm_configd and smad. To change the port numbers used by sm_configd or smad, edit the /etc/services files on all nodes. The files must be identical on all nodes. For all cases other than sm_configd and smad, you must change the application's port use rather than the cluster's.
