Last updated on MAY 26, 2019
Applies to:Oracle Fusion Middleware - Version 220.127.116.11.0 and later
Information in this document applies to any platform.
This applies to all Oracle Fusion Middleware 11g and 12c products as applies to "Administering Oracle Fusion Middleware" documentation referenced.
If you are on version 12.2.1.x, see <Note:2446265.1> for a streamlined explanation. The below content has been ongoing since 11g releases:
The purpose of this document is to provide a reference for steps on how to change the host name, domain name, or IP address of an Oracle Fusion Middleware host.
Ensure to read YOUR VERSION's documentation (provided below). Depending on your version, the hostname and ip address change may be limited to the the following component types:
Java components, such as Oracle SOA Suite and Oracle WebCenter components that are deployed to Oracle WebLogic Server.
Oracle Fusion Middleware Web Tier components, such as Oracle Web Cache and Oracle HTTP Server.
- An Oracle database that contains the metadata for Oracle Fusion Middleware components.
Note: It is not supported to change the hostname, domain or IP address of some installations. If an installation type or product is not mentioned in the Oracle Documentation, it is not supported, it has not been tested.
You may find that changing this machine configuration may work for your primary use case, but some installed components may fail. You may find that changing only the IP address to be more fault tolerant and you may run with this if acceptable to your requirements. However, it is not supported until tested, documented and approved by all product/components installed within the environment. An Enhancement Request has been filed and under consideration: "Bug 16093248 - ABILITY TO CHANGE IP ADDRESS, HOSTNAME AND/OR DOMAIN FOR ALL FMW".
Update: ER 16093248 is updated for 18.104.22.168 to provide a new chghost utility (chghost.sh | chghost.cmd ) to handle this change. See documentation links below. This includes more installation types, but does not include all. It is an active enhancement in-progress for different products.
