Checking /etc/services for DB2

On each system in the cluster, use the more command to check the file /etc/services.

Remember to perform the following:

  • Make sure each partition has a port number assigned. The number of reserved ports depends on the number of partitions.

  • Make sure that no other services use the ports. Manually assign new numbers if necessary.

  • Make sure all systems in the cluster have the same entries in the /etc/services file.

The following is an example for two DB2 instances: db2inst1 and db2inst2. Both instances have two partitions each. Each instance requires two ports plus one port per partition, hence four lines per instance.

# more /etc/services
DB2_db2inst1      60000/tcp
DB2_db2inst1_1    60001/tcp
DB2_db2inst1_2    60002/tcp
DB2_db2inst1_END  60003/tcp
DB2_db2inst2      60004/tcp
DB2_db2inst2_1    60005/tcp
DB2_db2inst2_2    60006/tcp
DB2_db2inst2_END  60007/tcp

Inspect the file and verify that no duplicate port numbers exist.
