You can use virtual host properties files to create or
change host alias properties.
Before you begin
Determine the changes that you want to make to your host
alias conifguration.
Start the wsadmin scripting tool. To start
wsadmin using the Jython language, run the wsadmin -lang Jython command
from the bin directory of the server profile.
About this task
Using a virtual host properties file, you can create,
modify, or delete a host alias. Run administrative commands using
wsadmin to configure or delete a host alias.
Table 1. Actions for host alias properties. You can create, modify, and delete host alias properties.
Action |
Procedure |
create |
Set properties and then run the applyConfigProperties
command. |
modify |
Edit the properties and then run the applyConfigProperties
command. |
delete |
Specify the host aliases to delete in the Properties
section and then run the deleteConfigProperties command. |
Optionally, you can use interactive mode with the commands:
AdminTask.command_name('-interactive')
Procedure
- Create a host alias.
- Edit a VirtualHost properties file so that it specifies
a host alias property.
Open an editor on a virtual host
properties file. You can copy an example properties file in this step
into an editor and modify the properties as needed for your situation.
The following example defines a host alias inside a virtual
host named default_host at the cell scope with host
name newHost and port 5555:
#
# Header
#
ResourceType=VirtualHost
ImplementingResourceType=VirtualHost
ResourceId=Cell=!{cellName}:VirtualHost=default_host
AttributeInfo=aliases(port,hostname)
#
#
#Properties
#
5555=newHost
EnvironmentVariablesSection
#
#
#Environment Variables
cellName=WASCell06
- Run the applyConfigProperties command to create a host
alias.
Running the applyConfigProperties command
applies the properties file to the configuration. In this Jython example,
the optional -reportFileName parameter produces a
report named report.txt:
AdminTask.applyConfigProperties(['-propertiesFileName myObjectType.props -reportFileName report.txt '])
- Modify an existing host alias.
- Obtain a virtual host properties file that defines the
host alias that you want to change.
You can extract
a properties file for a VirtualHost object using the extractConfigProperties
command.
- Open the properties file in an editor and change the
host alias properties as needed.
Ensure that the environment
variables in the properties file match your system.
- Run the applyConfigProperties command to change a host
alias.
- Delete an existing host alias.
If you no
longer need one or more host aliases, list the host aliases that you
want removed in the Properties section of the virtual host properties
file and then run the deleteConfigProperties command:
AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]')
Results
You can use the properties file to configure and manage
the host alias.
What to do next
Save the changes to your configuration.
