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
 

EMCA 开始于 2013-6-14 20:59:58
 EM Configuration Assistant, 11.2.0.0.2 正式版
 版权所有 (c) 2003, 2005, Oracle。保留所有权利。
 

输入以下信息:
 数据库 SID: orcl
 监听程序端口号: 1521
 监听程序 ORACLE_HOME [ /opt/oracle/app/oracle/product/11.2.0/dbhome_1 ]: /bin/lsnrctl
 SYS 用户的口令: 
 DBSNMP 用户的口令: 
 SYSMAN 用户的口令: 
 通知的电子邮件地址 (可选):
 通知的发件 (SMTP) 服务器 (可选):
 -----------------------------------------------------------------
 

已指定以下设置
 

数据库 ORACLE_HOME ................ /opt/oracle/app/oracle/product/11.2.0/dbhome_1
 

本地主机名 ................ wwr-ThinkPad-Edge
 监听程序 ORACLE_HOME ................ /bin/lsnrctl
 监听程序端口号 ................ 1521
 数据库 SID ................ orcl
 通知的电子邮件地址 ...............
 通知的发件 (SMTP) 服务器 ...............
 

-----------------------------------------------------------------
 是否继续? [是(Y)/否(N)]: y
 2013-6-14 21:01:53 oracle.sysman.emcp.EMConfig perform
 信息: 正在将此操作记录到 /opt/oracle/app/oracle/cfgtoollogs/emca/orcl/emca_2013_06_14_20_59_58.log。
 2013-6-14 21:01:54 oracle.sysman.emcp.EMConfig perform
 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。
 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。
 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。

Explain InnoDB Full-Text Search capabilities. Explain InnoDB Full-Text Search capabilities. Apr 02, 2025 pm 06:09 PM

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
