Installing DSC
Before using DSC, install it on a Linux or Windows server. DSC supports 64-bit Linux OSs. For details about other OSs supported by DSC, see Compatible OSs.
Prerequisites
- In Linux, do not install or perform operations on DSC as the root user. To execute the install.sh script, you must have the permission for creating folders.
- The size of the target folder must be at least four times that of the SQL files in the input folder.
For example, if the size of the SQL files in the input folder is 100 KB, the target folder must have available disk space of at least 400 KB to process the SQL files.
- To query the available disk space of the target folder in Linux, run the following command:
df -P <Folder path>
- To query the size of the input file in Linux, run the following command in the directory where the file resides:
ls -l
- To query the available disk space of the target folder in Linux, run the following command:
- JRE 1.8 or later and Perl have been installed. For details about the hardware and software requirements, see System Requirements.
To check the installed Java version and set the Java path, perform the following steps:
- Check whether the Java version meets requirements.
java -version
- Ensure that the Java path is correctly set.
- Linux
- Check whether the Java path is correctly set.
echo $JAVA_HOME
- If no information is returned, add the following two lines to the .bashrc file of the current user, save the modification, and exit.
Assume that the Java installation path is /home/user/Java/jdk1.8.0_141.
export JAVA_HOME=/home/user/Java/jdk1.8.0_141 export PATH=$JAVA_HOME/bin:$PATH
- Activate Java environment variables.
source ~/.bashrc
- Check whether the Java path is correctly set.
- Windows
- Right-click My Computer and choose Properties from the shortcut menu. The System window is displayed.
- Click Advanced System Settings. The System Properties dialog box is displayed.
- On the Advanced tab page, click Environment Variables. The Environment Variables dialog box is displayed.
- Select Path in the System variables area. Click Edit and check the Java installation path.
If the Java installation path does not exist or is incorrect, add the Java path of this PC to Path.
Assume that the Java installation path is C:\Program Files\Java\jdk1.8.0_141\bin and the environment variable in Path is c:\windows\system32;. Set Path to c:\windows\system32;C:\Program Files\Java\jdk1.8.0_141\bin;.
- Linux
- Check whether the Java version meets requirements.
