Verify your environment

Before running the tutorial, verify these environment settings:

For all platforms, the DJC_HOME environment variable must be set to the location of your EAServer installation.

For Windows, the PATH environment variable must include the EAServer lib subdirectory.

For UNIX platforms, the EAServer lib directory must be added to the shared library search path variable listed in Table 10-1 for your platform.

**Table 10-1: Shared library search path variables for UNIX platforms**
Platform	Variable name
Solaris	LD_LIBRARY_PATH
HP-UX	SHLIB_PATH
AIX	LIBPATH
Linux	LD_LIBRARY_PATH

Configuring the Windows environment

To configure the command line where you are running the tutorials, run these commands, substituting your EAServer installation location for eas-home:
```
set DJC_HOME=eas-home
set PATH=%DJC_HOME%\dll;%PATH%
```
You can also edit these variables in the System dialog for the Windows Control Panel, or create a batch file to configure the settings.

Configuring the UNIX environment for C shell

To configure the C shell session where you are running the tutorials, run these commands, substituting your EAServer installation location for eas-home, and the shared-library variable from Table 10-1 for LIB_PATH:
```
setenv DJC_HOME eas-home
setenv LIB_PATH $DJC_HOME/lib:$LIB_PATH
```

Configuring the UNIX environment for Bourne shell

To configure the Bourne shell session where you are running the tutorials, run these commands, substituting your EAServer installation location for eas-home, and the shared-library variable from Table 10-1 for LIB_PATH:
```
DJC_HOME=eas-home export DJC_HOME
LIB_PATH=$DJC_HOME/lib:$LIB_PATH export LIB_PATH
```
