TIP

This article assumes that you have read the getting started article.

Launch Arguments

The Theta Terminal can be configured to launch in different ways. This article will address all options you have at your disposal for customizing the launch.

Credentials File

Instead of specifying your login credentials as a launch argument, you can specify a file where the credentials are stored. Specifying credentials as launch arguments could be a security risk since the launch arguments are shown on some task managers. This is the solution to that security flaw. The creds file must contain 2 lines. The first line is the username or ThetaData email and the second line is the password.

Credentials File Contents

test@thetadata.net
mypassword123

Example

Where creds.txt is the name of the file. Providing the full path to the file might be required.

java -jar ThetaTerminal.jar creds=creds.txt

Memory Allocation

You can specify the amount of memory that your system will allocate towards the Theta Terminal by including:

-Xms: The starting amount of memory the Theta Terminal consumes.

-Xmx: The maximum amount of memory the Theta Terminal can consume.

Example

To initially allocate 4GB of RAM and set an upper limit of 8GB, where username and password are you ThetaData credentials.

java -Xms4G -Xmx8G -jar ThetaTerminal.jar username password

Enter password manually

Specifying no arguments will require you to enter your password manually.

java -jar ThetaTerminal.jar

Set the Line ID

You can add line=number as an argument to any of the above methods. This will use a different configuration file than config_0.properties. See our launching multiple terminals article for more information.
