File Descriptor Requirements (Linux Systems)
To Increase the File Descriptor Limit (Linux)
Installing the Directory Server
Configuring the JVM, Java Options, and Database Cache
Upgrading the Directory Server
Starting and Stopping the Directory Server
You must provide the directory server with information about the location of the Java installation that should be used by setting the OPENDS_JAVA_HOME environment variable. A potential problem could arise if the OPENDS_JAVA_HOME environment variable is not set, or does not point to the root of a valid (at least Java 5.0, JRE 1.5.0_08) installation. Alternatively, using the OPENDS_JAVA_BIN variable to point to the absolute path of the Java executable may be helpful if you want to use a 64-bit JVM rather than the default 32-bit version (for example, $JAVA/bin/sparcv9/java or $JAVA/bin/amd64/java.
The directory server's administrative scripts uses the OPENDS_JAVA_HOME environment variable. If the variable is not set, an error can occur.
