Ubuntu 12.04(amd64)安装完Oracle 11gR2后各种问题解决方法
上一篇介绍了怎么在Ubuntu上面安装Oracle数据库(见 ),整个安装过程还算顺利,但有些步骤没有执行成功,或者直接选择啦忽略,这可能导致安装完之后,不能正常使用,出现很多小问题。下面一一介绍。
1、找不到命令,无论是lsnrctl 还是sqlplus,都提示:未找到命令。原因是环境变量没有设置,打开/etc/profile文件,加入ORACLE_HOME这个环境变量。并将相关命令bin放到PATH后面。下面是profile文件部分内容:
export ORACLE_HOSTNAME=localhost
export JAVA_HOME=/opt/jdk1.6.0_43
export JRE_HOME=/opt/jdk1.6.0_43/jre
export ORACLE_HOME=/opt/oracle/app/oracle/product/11.2.0/dbhome_1
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$ORACLE_HOME/bin
export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib/tools.jar:$JAVA_HOME%/lib/dt.jar:$JAVA_HOME/lib:$JRE_HOME/lib
上述操作应该有root权限才行,之后执行 source /etc/profile ,使该文件生效。注意回到oracle用户(su oracle)后,还要执行一次 source /etc/profile,才可以生效,可以通过执行 echo $PATH 来查看相关命令是否添加成功。
2、经过步骤1之后,执行 lsnrctl start 启动监听服务,然后 sqlplus / as sysdba 出现,,
ERROR:
ORA-12162: TNS:net service name is incorrectly specified
错误原因不详,但是解决方法是在终端执行 export ORACLE_SID=orcl (或者将orcl固定在环境变量中,步骤同1),从解决方法也可以猜出问题所在了吧。
后出现
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
解决方法:
修改$ORACLE_HOME\network\admin\listener.ora文件
加上
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = 你的数据库名称)
(ORACLE_HOME = D:\oracle\product\10.1.0\db_1)
)
)
上面SID_NAME=orcl,然后重启lisener服务,就ok了。
之后顺利进入sqlplus环境,通过startup命令启动数据库。
3、无法通过网页进入em,相关服务未启动。在终端执行 emctl start dbconsole 后,出现
OC4J Configuration issue. /opt/oracle/app/oracle/product/11.2.0/dbhome_1/oc4j/j2ee/OC4J_DBConsole_wwr-ThinkPad-Edge_orcl not found.
但是这个文件夹确实存在啊!可见提示的错误信息未必是问题的真正原因。接下来
emca -config dbcontrol db -repos recreate 出现如下信息:
oracle@wwr-ThinkPad-Edge:~$ emca -config dbcontrol db -repos recreate

无法完成配置。 有关详细资料, 请参阅 /opt/oracle/app/oracle/cfgtoollogs/emca/orcl/emca_2013_06_14_20_59_58.log 中的日志文件。
接着百度“严重: 监听程序未启动或数据库服务未注册到该监听程序。启动该监听程序并注册数据库服务, 然后重新运行 EM Configuration Assistant。”,找到如下解决方法
在终端执行,export ORACLE_HOSTNAME=localhost ,即设置ORACLE_HSOTNAME这个环境变量的值为localhost,再次启动em相关服务(emctl start dbconsole),成功从网页进入em。
