ORACLE OEM重建

一、Oracle OEM開啓失敗---環境變量ORACLE_UNQNAME未定義問題

登陸https://h1:1158/em 之後,看到數據庫實例都是關閉的.啓動不了
(1)查看dbconsole狀態:emctl status dbconsole

顯示:Environment variable ORACLE_UNQNAME not defined. Please define it.

解決方法：

在啓動的時候先設置一下oracle_unqname

set oracle_unqname=$ORACLE_SID

如果還是失敗，在環境變量中添加：

[oracle@h1 ~]$  vi ~/.bash_profile

    在最後添加：export  ORACLE_UNQNAME=$ORACLE_SID   

[oracle@h1 ~]$ source  ./bash_profile 

    使環境變量生效

 

2.emctl   start  dbconsole

如果還出現上述的錯誤：刪除dbconsole重新配置

[oracle@h1 ~]$ emca -deconfig dbconsole db -repos drop

3.如果刪除失敗，則舊數據清除

[oracle@h1 ~]$ sqlplus "/as SYSDBA"

SQL*Plus: Release 11.2.0.1.0 Production on Thu Mar 14 21:08:54 2013

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

#(1)進入數據庫刪除dbconsole以前的用戶，並且修改DBSNMP密碼

SQL> alter user dbsnmp identified by manager;

 

 

#(2)刪除早期DBCONSOLE創建的用戶：

sql>drop role MGMT_USER;

sql>drop user MGMT_VIEW cascade;

sql>drop user sysman cascade;

 

#(3)刪除早期DBCONSOLE創建的對象：

sql>drop PUBLIC SYNONYM MGMT_TARGET_BLACKOUTS;

sql>drop public synonym SETEMVIEWUSERCONTEXT;

 

 

4. 重新創建DBCONSOLE：（如果是在windows下，要先到註冊表刪除DBCONSOLE的服務，重啓電腦）

emca -config dbcontrol db -repos create

根據提示，先輸入SID，再輸入Y繼續；

輸入端口1521，輸入SYS密碼，輸入DBSNMP密碼，輸入SYSMAN 密碼，輸入Y繼續

完成。

 

5.emca 命令的日誌在

/app/oracle/cfgtoollogs/emca/ORCL/

日誌有兩個，一個是概況，一個是明細

 

6.OEM開啓

7.OEM常用的命令

（1）創建一個EM資料庫 -

emca –repos create -

（2）刪除一個EM資料庫 -

emca –repos drop -

（4）配置數據庫的DatabaseControl -

emca –config dbcontrol db -

（5）刪除數據庫的DatabaseControl配置 -

emca –deconfig dbcontrol db -

（6）重新配置db control的端口，默認端口在1158 -

emca –reconfig ports -

emca –reconfig ports -dbcontrol_http_port 1160 -

emca -reconfigports -agent_port 3940 -

（7）先設置ORACLE_SID環境變量後,啓動EM console服務 -

emctl start dbconsole -

（8）先設置ORACLE_SID環境變量後,停止EM console服務 -

emctl stop dbconsole -

（9）先設置ORACLE_SID環境變量後,查看EM console服務的狀態 -

emctl status dbconsole -

（10）配置dbconsole的步驟 -

emca -reposcreate -

emca -configdbcontrol db -

emctl start dbconsole -

（11）重新配置dbconsole的步驟 -

emca –repos drop -

emca –repos create -

emca –config dbcontrol db -

emctl start dbconsole
