9.To enable the communication between the partitions, edit the /etc/services, /etc/ hosts, .rhosts file with the required entries.

Edit the/etc/hosts file by adding the IP address and hostname of the DB2 server. For example:

[payroll_inst@node1 ~]> vi /etc/hosts 10.0.0.1 DBNODE.domainname.com DBNODE

Edit the ~/.rhosts file for the instance owner:

For example:

[payroll_inst@node1 ~]> vi home/payroll_inst/.rhosts

node1 payroll_inst

node2 payroll_inst

10.As root, edit the /etc/services file to ensure that enough ports are reserved for Fast Communication Manager (FCM) to allow inter-partition communications. Add the following entries in the /etc/services file. The number of ports reserved depends upon the requirement.

[root@node1/]>vi /etc/services

db2c_payroll_inst 50000/tcp # DB2 connection service port

DB2_payroll_inst 60000/tcp DB2_payroll_inst_1 60001/tcp DB2_payroll_inst_2 60002/tcp DB2_payroll_inst_3 60003/tcp DB2_payroll_inst_4 60004/tcp DB2_payroll_inst_5 60005/tcp DB2_payroll_inst_6 60006/tcp DB2_payroll_inst_7 60007/tcp DB2_payroll_inst_8 60008/tcp DB2_payroll_inst_END 60009/tcp
