We've recently received many inquiries on how to configure Oracle E-Business Suite application and database tiers to use logical hostnames. To help with this, we have just published a new Note:

This new Note describes how to configure a machine to use a logical hostname, and the subsequent use of Rapid Install or Rapid Clone to configure the file system.  There is also a discussion of the different scenarios in which logical hostnames can be employed.

Many of the examples shown depict E-Business Suite Release 12.2 on Linux 64-bit, but the fundamental concepts also apply to Releases 12.0 and 12.1, and to other operating systems.

Employing logical hostnames offers several distinct advantages:

  • Hides from the end users the physical servers that host the applications software
  • Reduces configuration changes needed in network reconfiguration, data center migration, and disaster recovery
  • Facilitates the creation of an identical copy (clone) if needed
  • Avoids the need to clone a system just to change the hostname

The Note covers three different scenarios:

  1. Using logical host names in creation of an identical clone - How using logical hostnames can aid in the creation of a system that is identical to the original system in every way except for the different physical hostname and network address.  
  2. Using logical host names to avoid rewiring after changes in network configuration - How logical hostnames can minimize the impact of necessary host name and IP address changes.  
  3. Using logical host names to faciliate enabling Oracle WebLogic Administration Server high availability - How either a standby virtual machine or standby physical server can be used to achieve high availability of the Admin Server if the Admin Server and the standby system share the same logical hostname.
