环境:redhat 5.8-64bit
db: oracle 11.2.0.4- 64bit
准备继续学习下ocp的相关知识点,在vm中创建oem,其中一些emca、emctl用法和在操作中出错的情景,详细如下:
=====1、emca和emctl用法
1,修改DBSNMP密码:
重新配置DBCONSOLE,需要输入DBSNMP密码,但任何密码都会显示错误,需要预先修改。
sql>alter user dbsnmp identified by xxx;
2,删除早期DBCONSOLE创建的用户:
sql>drop role MGMT_USER;
sql>drop user MGMT_VIEW cascade;
sql>drop user sysman cascade;
3,删除早期DBCONSOLE创建的对象:
sql>drop PUBLIC SYNONYM MGMT_TARGET_BLACKOUTS;
sql>drop public synonym SETEMVIEWUSERCONTEXT;
4,重新创建DBCONSOLE:(如果是在windows下,要先到注册表删除DBCONSOLE的服务,重启电脑)
$emca -config dbcontrol db -repos create
如果此命令还是失败,可直接利用重建命令:
$emca -config dbcontrol db -repos recreate
根据提示,先输入SID,再输入Y继续;
输入端口1521,输入SYS密码,输入DBSNMP密码,输入SYSMAN 密码,输入Y继续
完成。
5,检查状态 emctl status dbconsole。
附emca常用命令:
创建一个EM资料库
emca -repos create
重建一个EM资料库
emca -repos recreate
删除一个EM资料库
emca -repos drop
配置数据库的 Database Control
emca -config dbcontrol db
删除数据库的 Database Control配置
emca -deconfig dbcontrol db
重新配置db control的端口,默认端口在1158
emca -reconfig ports
emca -reconfig ports -dbcontrol_http_port 1160
emca -reconfig ports -agent_port 3940
先设置ORACLE_SID环境变量后,启动EM console服务
emctl start dbconsole
先设置ORACLE_SID环境变量后,停止EM console服务
emctl stop dbconsole
先设置ORACLE_SID环境变量后,查看EM console服务的状态
emctl status dbconsole
配置dbconsole的步骤
emca -repos create
emca -config dbcontrol db
emctl start dbconsole
重新配置dbconsole的步骤
emca -repos drop
emca -repos create
emca -config dbcontrol db
emctl start dbconsole
-------------------------------------------------------------------------------------------------------------------------
Oracle 10G重建EM DB Control.
1.drop configuration files and repository run :
emca -deconfig dbcontrol db -repos drop
2. Logon SQLPLUS as user SYS or SYSTEM, and drop the sysman account and mangement objects:
a. drop user sysman cascade;
b. drop role MGMT_USER;
c. drop user MGMT_VIEW cascade;
d. drop public synonym MGMT_TARGET_BLACKOUTS;
e. drop public synonym SETEMVIEWUSERCONTEXT;
3.Create configuration files and repository run
emca -config dbcontrol db -repos create
创建EM时,提示的端口号,应为实例的断口号,比如1521,不是EM的端口号(比如1158)
EM的端口号在这个文件中可以查到10.2.0\db_1\sysman\config\emca.properties
然后,进行em后,界面出来了,但报了一个错:
Java.lang.Exception: Exception in sending Request :: null
很多功能不能用,提示重新登录.
在Oracle论坛上查到了解决办法:
http://forums.oracle.com/forums/thread.jspa?threadID=320574&tstart=0&messageID=1374397
找到下面的文件
10.2.0\db_1\ZYKNET_ORC2\sysman\config\emd.properties
其中的agentTZRegion缺省是GMT,改为你所在的时区即可,例如:
agentTZRegion=Asia/Chungking
关于时区的列表参考:10.2.0\db_1\sysman\admin\supportedtzs.lst
然后,重启OracleDBConsole
=====2、操作时出错的情景
1. emca: 按要求配置了.bash_profile中的环境变量
-
ORACLE_UNQNAME=orcl; export ORACLE_UNQNAME
-
ORACLE_HOSTNAME=srv1; export ORACLE_HOSTNAME
ORACLE_HOMENAME配置时,开始配置了localho
st
EM Configuration issue. /u01/app/oracle/product/10.2.0/db_1/localhost_orcl not found.
2. emca配置用户locked问题
srv1:/home/oracle> emca -config dbcontrol db -repos create

WARNING: ORA-28000: the account is locked
这个地方 DBSNMP用户被locked了,需要解锁
sysdba用户: alter user sysman account unlock;即可
|
3. 由于开始时配置ORACLE_HOSTNAME=localhost,导致出错,只能用命令
emca -config dbcontrol db -repos recreate重新创建下
-
srv1:/home/oracle> emca -config dbcontrol db -repos recreate

创建完毕,成功!!
