If you decide not to use a DNS in your configuration, you need to provide your IBM
SSR with information in addition to the information in the Communication Resources
(Copy Services) work sheet. The SSR uses the ESS Service interface to update the
host table with this information:
v
The TCP/IP address and host name for each ESS cluster in the copy services
server group.
v
The TCP/IP address and hostname for each host using the CLI.
v
The TCP/IP address and hostname of the ESSNet Workstation.
Use the following instructions when completing the Communication Resources (ESS
Web Copy Services) work sheet in “Appendix B. Communication Resources (ESS
Web Copy Services) work sheet” on page 89. Refer to the “Guidelines for enabling
and using ESS Web Copy Services” on page 41 for additional information:
Attention: This work sheet must be copied and provided for each ESS Web copy
services server group defined
1. Server Group : Identify the server group (_) that is being defined by this work
