这两天首先是把操作系统搞挂了，于是重新装了个系统，刚装好Oracle数据库，又把OEM搞坏了，因为是Ghost的系统，觉得计算机名不好，于是换了个，之后OEM就挂了。从网上了大半天也没搞定. 最终还是在oracle的metelink上找到了答案，20分钟就把OEM修好了。总结如下： ­

手工重新配置dbconsole的步骤
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
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。

Purpose ­

This article provides detailed instructions on how to 1) create, 2) drop and 3)recreate the repository and configuration files for the DB Control application used to manage a single10gDatabase. ­

Scope and Application ­

The steps in this article are written for a DBA or System Administrator who needs to create, drop or reconfigure the DB Control Application. ­

­

The format of the document will include steps for both 10.1 and 10.2 EMCA because the commands changed between the two releases. ­

For detailed instructions on DB Control 10.2 for RAC, please consult also: ­

How To Drop, Create And Recreate DB Control In A10gDatabase ­

­

DB Control options: ­

­

A.  Delete DB Control Objects: ­

Option 1.  Delete DB Control Configuration Files using EMCA scripts ­

Option 2.  Delete DB Control Configuration Files Manually: ­

Option 3.  Delete DB Control Repository Objects using RepManager ­

Option 4.  Delete DB Control Repository Objects Manually ­

Option 5.  Delete DB Control Configuration Files and Repository Objects using EMCA ­

­ ­

Option 1. Delete DB Control Configuration Files using EMCA scripts:

For DB Control 10.1.x, run the command: /bin/emca -x ­

For DB Control 10.2.x, run the command: bin/emca -deconfig dbcontrol db ­

Important Note: the option -deconfig removes the EM jobs from Scheduling before the DB Control is deconfigured. Otherwise the repository, which is not dropped, could be corrupted or inconsistent if EM jobs were scheduled as the time the DB Control is dropped. It could also cause some errors during the DB Control deletion. ­

­

Option 2. Delete DB Control Configuration Files Manually: ­Remove the following directories from your filesystem: ­

­

/ ­

/oc4j/j2ee/OC4J_DBConsole__ ­

NOTE: ­

On Windows you also need to delete the DB Console service: ­

- run regedit ­

- navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services ­

- locate the OracleDBConsole entry and delete it ­

­

Alternatively on Windows XP and Windows Server 2003 you can run the following from the command line: ­

'sc delete ' ­

­

- where is the DB Control service name (typically: OracleDBConsole) ­

­

Also available from Microsoft is the delsrv.exe command.   (Free download from Microsoft) ­

­

­ ­

Option 3. Delete DB Control Repository using RepManager:

This option is not as complete as the other options.  You may find that dropping the repository using the commandline options is a better solution.  Also note, RepManager is not used to create a DB Control Repository. ­

In both10gR1 and R2 run: ­

/sysman/admin/emdrep/bin/RepManager -action drop ­

Warning: this command puts the database in Quiesce Mode. ­

Please consult thehttps://metalink2.oracle.com/metalink/plsql/showdoc?db=NOT&id=375946.1&blackframe=1Running EMCA Results in Database quiesce And No ­

New Connections or Operations Can Be Performed During the DB Control Repository Creation ­

­

Option 4. Delete DB Control Repository Objects ManuallyStep 1: Drop AQ related objects in the SYSMAN schema ­

Logon SQLPLUS as user SYSMAN ­

SQL> exec DBMS_AQADM.DROP_QUEUE_TABLE(queue_table=>'MGMT_NOTIFY_QTABLE',force =>TRUE); ­

­

Step 2: Drop the DB Control Repository Objects ­

Logon SQLPLUS as user SYS or SYSTEM, and drop the sysman account and management objects: ­

SQL> SHUTDOWN IMMEDIATE; ­

SQL> STARTUP RESTRICT; ­

SQL> EXEC sysman.emd_maintenance.remove_em_dbms_jobs; ­

SQL> EXEC sysman.setEMUserContext('',5); ­

SQL> REVOKE dba FROM sysman; ­

SQL> DECLARE ­

CURSOR c1 IS ­

SELECT owner, synonym_name name ­

FROM dba_synonyms ­

WHERE table_owner = 'SYSMAN'; ­

BEGIN ­

FOR r1 INc1 LOOP ­

IF r1.owner = 'PUBLIC' THEN ­

EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM '||r1.name; ­

ELSE ­

EXECUTE ­

IMMEDIATE 'DROP SYNONYM '||r1.owner||'.'||r1.name; ­

END IF; ­

END LOOP; ­

END; ­

/ ­

SQL> DROP USER mgmt_view CASCADE; ­

SQL> DROP ROLE mgmt_user; ­

SQL> DROP USER sysman CASCADE; ­

SQL> ALTER SYSTEM DISABLE RESTRICTED SESSION; ­

Note: The above will completely delete the DB Control repository from the database; under certain circumstances (e.g. you want to recreate the repository later on) the following statements may be sufficient to remove the repository: ­

Logon SQLPLUS as user SYS or SYSTEM, and drop the sysman account and management objects: ­

SQL> drop user sysman cascade; ­

SQL> drop role MGMT_USER; ­

SQL> drop user MGMT_VIEW cascade; ­

SQL> drop public synonym MGMT_TARGET_BLACKOUTS; ­

SQL> drop public synonym SETEMVIEWUSERCONTEXT; ­

­For DB Control 10.1.x, dropping both the configuration files and the repository objects is a two step process.  Run the following two commands: ­

Option 5. Delete DB Control Configuration Files and Repository Objects using EMCA ­

­

/bin/emca -x ­

/sysman/admin/emdrep/bin/RepManager -action drop ­ ­

For DB Control 10.2.x, both configuration files and repository objects can be deleted with a single command.  Run the command: ­

/bin/[B]emca -deconfig dbcontrol db -repos drop

­

Warning: this command puts the database in Quiesce Mode. ­

New Connections or Operations Can Be Performed During the DB Control Repository Creation ­

­

B. Create DB Control Objects ­

Option 1.  Create the DB Control Configuration Files ­

Option 2.  Create the DB Control Repository Objects and Configuration Files ­

Option 1.  Create the DB Control Configuration Files ­

To create only the DB Control configuration files, skipping the repository creation (this would be done for instance if you dropped only the files and left the repository in place): ­

For DB Control 10.1.x, run the command: /bin/emca -r ­

For DB Control 10.2.x, run the command: /bin/emca -config dbcontrol db ­

­

Option 2. Create the DB Control Repository Objects and Configuration Files ­

For DB Control 10.1.x, run the command: /bin/emca ­

For DB Control 10.2.x, run the command: bin/emca -config dbcontrol db -repos create ­

Warning: this command puts the database in Quiesce Mode. ­

Please consult thehttps://metalink2.oracle.com/metalink/plsql/showdoc?db=NOT&id=375946.1&blackframe=1Running EMCA Results in Database quiesce And No ­

New Connections or Operations Can Be Performed During the DB Control Repository Creation ­

­

C.  Recreate/ReConfig DB Control ­

Option 1.  Recreate the DB Control Configuration Files only (leave Repository intact) ­

Option 2.  Recreate the DB Control Configuration Files and Repository ­

­

In 10.2, the EMCA commands can be used to reconfigure the existing installs without removing them first. ­

­

Option 1. Recreate the DB Control Configuration Files only (leave Repository intact): ­

For DB Control 10.2.x, run the command: ­

/bin/emca -config dbcontrol db ­

­ ­

Option 2. Recreate the DB Control Configuration Files and Repository ­

For DB Control 10.2.x, run the command:/bin/[B]emca -config dbcontrol db -repos recreate

­

Warning: this command puts the database in Quiesce Mode. ­

附： ­

Note that this command puts the database in Quiesce Mode.Please consult the Note 375946.1­

Applies to: Enterprise Manager Grid Control - Version: 10.2.0.1 to 11.1.0.7­

This problem can occur on any platform.­

SymptomsWhen running 'emca -config dbcontrol db -repos recreate' or 'emca -deconfig dbcontrol db -repos drop' to recreate or drop the Enterprise Manager Database Control configuration files and repository the operation hangs and at the same time users are not able to login to the database. CauseThe emca command, when recreating or dropping the repository, requires the database to be quiesced.  This means that, temporarily, no operations are possible on the database and new users cannot login.­

­

If there are active sessions on the database at the time the quiesce operation will hang pending their completion, during which time no new users will be able to connect.­

­

SolutionTo implement the solution, please execute the following steps:­

­

1. Kill the emca command­

2. Connect to the database with SYS account through SQL*Plus­

     SQL > alter system unquiesce;­

­

Run the emca command at a time when there is low system usage.­
