Oracle 10G重建EM DB Control

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

建立EM時,提示的埠號,應為例項的埠號,比如1521,不是EM的埠號(比如1158)
EM的埠號在這個檔案中可以查到10.2.0/db_1/sysman/config/emca.properties然後,進行em後,介面出來了,但報了一個錯:
java.lang.Exception: Exception in sending Request :: null
很多功能不能用,提示重新登入.
找到下面的檔案10.2.0/db_1/ZYKNET_ORC2/sysman/config/emd.properties
其中的agentTZRegion預設是GMT,改為你所在的時區即可,例如:
agentTZRegion=Asia/Chungking
關於時區的列表參考：10.2.0/db_1/sysman/admin/supportedtzs.lst
然後，重啟OracleDBConsole[@more@]
