Command Line Options: Display Server  

The following command line arguments are enabled when you run the Display Server  from a Windows Command Prompt or UNIX terminal window. For command line options for your data source, refer to the Data Sources section of this documentation.

NOTE: If a command line argument contains a space or a semicolon, then the entire argument must be enclosed in quotes (e.g.: "-sub:$data:my Data").
 
Name Description
-daemon Run the Display Server as a daemon process. NOTE: This parameter must be the first command line argument given.

Example:
run_displayserver -daemon

-dataserver: (filename)

Read data from Data Server output file instead of directly from data sources.If no file name is specified, default output file (rtvdata.xml) will be used. If necessary, include local directory path or http URL.

Example:
-dataserver:rtvdata.xml

//(host:port)

Read data from Data Server via socket instead of directly from data sources. If no host is specified, local host will be used. If no port is specified, default port (3278) will be used.

Example:
-dataserver://remotehost:8723

remote:http://host:port/rtvdata

Read data from Data Server via servlet instead of directly from socket. The host is web server hosting the servlet. The port is port used by the web server.

Example:
-dataserver:remote:http://host:port/rtvdata

name;connect

Specify named data server(s). The name is the Name specified when this data server was configured and connect is either host:port or http://host:port/rtvdata.

Example:
-dataserver:name=MyDataServer;connect=localhost:56789
-dataserver:name=London;connect=https://londonServer:8080/rtvdata

-dsenable:(dskey) Enable data source(s) for data attachments and defined commands that have been configured to bypass data being redirected through the specified data server(s).

The dskey is the abbreviation for the data source as listed in the Attach to Data and Define Command drop down menus, but in all lower case.

Example:
-dsenable:sql

-imageformat Specify image format: jpg or png. By default, the Display Server will automatically select the image that results in the fewer number of bytes for each display.

Example:
-imageformat:jpg

-imagequality: A value between 0 and 100 which controls the quality of the generated images. If the value is 100, the Display Server will output the highest quality image with the lowest compression. If the value is 0, the Display Server will output the lowest quality image using the highest compression. Default is 75.

Example:
-imagequality:75

-jmxport:(port number) The port number to use to expose JMX methods to monitor and manage the Display Server. There is no default port. If not specified, these JMX methods will not be accessible.

Example:
-jmxport:9998

-passclientlogin Pass Enterprise RTView login information into all data sources that have the Use Client Credentials option enabled.

NOTE: Some data sources do not support this feature. For information on Application Options for your data source, refer to the Data Sources section of this documentation.

Example:
-passclientlogin

tab
space

=
<
>
'
"
& / \ { } [ ] ( )

If your substitution value contains single quotes, you must escape them using a /.

Example:
-sub:$1:myValue

-sub:$filter:Plant=/'SanFrancisco/'

-timezone Set the default timezone for interpreting and displaying dates. Include a Java timezone ID or a custom ID, such as "GMT-8:00".  Unrecognized IDs will be treated as GMT. 

If you run the Enterprise RTView Builder with a valid timezone parameter and then save Application Options, the timezone information will be persisted.

To prevent the persisted timezone value from being used, pass "none" as the timezone ID.

Example:
-timezone:US/Eastern 

-timezone:none

Example:
-u5000 (updates every 5 seconds)
