DataStax DevCenter

Note

The recommended setup for DataMiner storage is Storage as a Service.

This tool allows you to perform CQL queries or run scripts on a Cassandra database. It can be used on any server using a Cassandra database.

Older DataMiner installers included this tool, but recent DataMiner installers (v10.2 or higher) do not deploy this tool and do not set the JAVA_HOME variable during installation, which means you will need to install it yourself and set the JAVA_HOME variable.

Tip

• To download this tool, see Downloading DataStax DevCenter.
• To install this tool, see Installing DataStax DevCenter.
• For general information on how to use this tool, see Using DataStax DevCenter.

If the tool has been installed on the DMA, to open the tool, go to the folder C:\Program Files\Cassandra\DevCenter\ and double-click Run DevCenter.lnk.

Setting the JAVA_HOME variable

To be able to use this tool, the JAVA_HOME variable must be set. You can set this variable by either creating a shortcut or changing the system variable.

Creating a shortcut

1. Create a shortcut of C:\Program Files\Cassandra\DevCenter\DevCenter.exe.

2. In the properties of that shortcut, fill in the following target:

   %windir%\System32\cmd.exe /c "set JAVA_HOME=C:\PROGRA~1\CASSAN~1\Java && set PATH=C:\PROGRA~1\CASSAN~1\Java\bin;%PATH% && start C:\PROGRA~1\CASSAN~1\DEVCEN~1\DEVCEN~1.EXE"
   

Changing the system variable

1. Open a command prompt as administrator and set the environment variable as follows:

   setx /m JAVA_HOME "C:\Program Files\Cassandra\Java"
   

2. Verify if the system variable has been set correctly by opening a new command prompt and entering the following command:

   echo %JAVA_HOME%
   

   The result should show the configured path.
