设置OpenDJ的JAVA运行内存：
修改java虚拟机参数配置文件java.properties,例如文件位置在/home/bjca_user/bjca/OpenDJ-2.4.6/config/java.properties。
将overwrite-env-java-args=false 改成overwrite-env-java-args=true
修改start-ds.java-args项，根据服务器实际情况配置JAVA内存，例如： start-ds.java-args=-Xms1024m -server
在linux系统服务中增加OpenDJ，实现OpenDJ随系统启动，同时重启OpenDJ服务让之前修改的配置生效。进入bin目录，例如：/home/bjca_user/bjca/OpenDJ-2.4.6/bin，运行如下命令：
#sudo create-rc-script --outputFile /etc/init.d/opendj
#chkconfig --add opendj
#service opendj stop
#service opendj start
