TCP/IP settings

TCP/IP ports are used by the fast communications manager (FCM).

Maximum logical partitions shows the number of ports that will be reserved for TCP/IP communications between the database partitions.

Type the numbers for the ports that you want to allocate for communications between database partitions in the Maximum logical partitions fields.

You require one port for each logical partition in an instance on this computer. Change the maximum number of logical partitions per computer, if required.

TCP/IP start port shows the beginning of the TCP/IP port range, which is 60000, by default. The node configuration file will have one port assigned to each logical partition on a computer. The first logical partition on each computer will use the start port number. Each additional logical partition will have a port number that increments by 1.

The DB2 Setup wizard verifies that the port range you specify is available on this server. However, you must ensure that this range is available on all other servers that will take part in this partitioned database environment.

Verify the availability of the ports that you specify by checking the /etc/services file on each computer that is to be used in this partitioned database environment.
