Configuring the Environment Variable

The following environment variables need to be set in order to use the CUBRID. The necessary environment variables are automatically set when the CUBRID system is installed or can be changed, as needed, by the user.

CUBRID Environment Variables
  • CUBRID : The default environment variable that designates the location where the CUBRID is installed. This variable must be set accurately since all programs included in the CUBRID system uses this environment variable as reference.
  • CUBRID_DATABASES : The environment variable that designates the location of the database location information file. The CUBRID system saves and manages the absolute path of database volumes that are used in the $CUBRID_DATABASES/databases.txt file. See databases.txt file.
  • CUBRID_LANG : The environment variable that designates the language that will be used in the CUBRID system. Currently, CUBRID provides English (en_US) and Korean (ko_KR.euckr and ko_KR.utf8). it is not a mandatory setting. Therefore, if the variable has not been set, then refer to the LANG environment variable or use en_US, which is the default value. See  Language Setting.

The above mentioned environment variables are set when the CUBRID is installed. However, the following commands can be used to verify the setting.

For Linux :

% printenv CUBRID

% printenv CUBRID_DATABASES

% printenv CUBRID_LANG

In Windows :

C:\> set CUBRID

OS Environment and Java Environment Variables
  • PATH : In the Linux environment, the directory $CUBRID/bin, which includes a CUBRID system executable file, must be included in the PATH environment variable.
  • LD_LIBRARY_PATH : In the Linux environment, $CUBRID/lib, which is the CUBRID system’s dynamic library file (libjvm.so), must be included in the LD_LIBRARY_PATH (or SHLIB_PATH or LIBPATH) environment variable.
  • Path : In the Windows environment, the $CUBRID/bin, which is a directory that contains CUBRID system’s execution file, must be included in the Path environment variable.
  • JAVA_HOME : To use the Java stored procedure in the CUBRID system, the Java Virtual Machine (JVM) version 1.6 or later must be installed, and the JAVA_HOME environment variable must designate the concerned directory.
    See the Environment Configuration for Java Stored Functions/Procedures.
Configuring the Environment Variable

For Windows

If the CUBRID system has been installed in the Windows environment, then the installation program automatically sets the necessary environment variable. Select [Systems Properties] in [My Computer] and select the [Advanced] tab. Click the [Environment Variable] button and check the setting in the [System Variable]. The settings can be changed by clicking on the [Edit] button. See the Windows help for more information on how to change the environment variable in the Windows environment.

For Linux

If the CUBRID system has been installed in the Linux environment, the installation program automatically creates the .cubrid.sh or .cubrid.csh file and makes configurations so that the files are automatically called from the installation account’s shell log-in script. The following is the .cubrid.sh environment variable setting file that was created in an environment that uses sh, bash, etc.

CUBRID=/home1/cub_user/CUBRID

CUBRID_DATABASES=/home1/cub_user/CUBRID/databases

CUBRID_LANG=en_US

ld_lib_path=`printenv LD_LIBRARY_PATH`

if [ "$ld_lib_path" = "" ]

then

LD_LIBRARY_PATH=$CUBRID/lib

else

LD_LIBRARY_PATH=$CUBRID/lib:$LD_LIBRARY_PATH

fi

SHLIB_PATH=$LD_LIBRARY_PATH

LIBPATH=$LD_LIBRARY_PATH

PATH=$CUBRID/bin:$CUBRID/cubridmanager/:$PATH

export CUBRID

export CUBRID_DATABASES

export CUBRID_LANG

export LD_LIBRARY_PATH

export SHLIB_PATH

export LIBPATH
