启动OracleDBConsoleorcl服务，出现错误，报错错误代码2。
产生原因大概为，改ip或者主机名字
解决办法为：
oracleproduct10.2.0db_1文件夹下
复制 db_1(你的域名)_orcl
为
db_1localhost_orcl
db_1hostName_orcl
db_1hostName_orcl
然后同样这样做在如下目录
db_1/oc4j/j2ee/OC4J_DBConsole_localhost_orcl
db_1/oc4j/j2ee/OC4J_DBConsole_hostname_orcl
db_1/oc4j/j2ee/OC4J_DBConsole_hostname_orcl
