Restrictions on Host Names for Siebel Gateway Name Server and Siebel Server
This topic is part of Planning Your Siebel Deployment.
See also Restrictions on Names for Siebel Enterprise and Siebel Server, which is about names for Siebel entities that you specify during configuration.
This topic describes restrictions for host names for server computers on which you will install Siebel Gateway Name Server or Siebel Server.
The Siebel Gateway Name Server name is defined automatically based on the host name of the server computer. However, problems might arise during configuration of Siebel modules unless the following requirements are observed:
- Host names for Siebel Gateway Name Server or Siebel Server must not include dashes (hyphens). It is recommended that you use an underscore if a separator character is required. For example, host_sba81 is acceptable, but host-sba81 is not.
NOTE: A dash might not cause problems in every scenario, but problems have been observed in many specific scenarios, as noted in 477993.1 (Article ID) on My Oracle Support. This document was previously published as Siebel Alert 1067. (Workarounds described in the alert, involving substitute *.scm files, do not apply to the current software version.) In any case, similar restrictions for naming a Siebel Enterprise or Siebel Server are noted in Restrictions on Names for Siebel Enterprise and Siebel Server.
- The host name for Siebel Gateway Name Server must be no longer than 15 characters.
The Siebel Configuration Wizard task for configuring the Siebel Gateway Name Server cannot execute successfully if the host name is longer than 15 characters.
(Configuration Wizard tasks for configuring the Siebel Enterprise and the Siebel Server also validate that the name of the Siebel Gateway Name Server, which would have been previously configured, is no longer than 15 characters.)
- In general, it is recommended not to define the host name for the Siebel Gateway Name Server computer to include domain information, as might be common in some UNIX environments. The entire host name is subject to the 15-character limit mentioned previously.
