Syntax

The syntax of the script is:

updwashost -instance instance [ -newhost new_host ]
  [ -changenode -oldhost old_host ] [ -regenplugin ] [ -verbose ] [ -help ]

Parameters

The parameters of the script are:

• -instance
  This is a required parameter. The value instance specifies the name of the instance that you want to update. To update the host name for all instances, specify ALL.

• -newhost
  Optional. The value new_host specifies the new host name to use for the instance. The default value is the current host name of the server.

• -changenode
  Optional. If you specify this parameter, the script changes the node name in the instance. If you specify this parameter, the -oldhost parameter is required.

• -oldhost
  This parameter is required if the -changenode parameter is specified, and not valid otherwise. The value specifies the old host name to use when changing the node name for the instance(s). The value specified will be replaced in the node name with the value specified in the -newhost parameter.

• -regenplugin
  This optional parameter will call the GenPluginCfg script after updating the host for the instance(s) to regenerate the HTTP server plugin configuration.

• -verbose
  This optional parameter turns on verbose messages, which can be helpful if you need to debug the script.

• -help
  This optional parameter displays the help message. If you specify this parameter, the script ignores all other parameters.
