PROPOSED SOLUTION JUSTIFICATION(S)
==================================
After the hostname changes the DBConsole must be recreated to update the repository tables. 
SOLUTION / ACTION PLAN
======================
-- To implement the solution, please execute the following steps::
Prepare the environment: 
- Open a new terminal window.
- Go to the Oracle installation folder.
- Set the ORACLE_HOME variable according to that folder.
eg. export ORACLE_HOME=/opt/oracle/db1 
Please follow the steps below. 
1. Stop the dbconsole on the target node 
$ORACLE_HOME/bin/emctl stop dbconsole 
2. Delete the repository and directory structure using EMCA: 
- go to $ORACLE_HOME/bin
- at the command prompt, enter the following command:
$PROMPT> emca -deconfig dbcontrol db -repos drop
- follow the instructions on the screen 
3) If this returns successfully please go to step 5, otherwise follow step 4. 
4) If the EMCA returns in any error please remove the repository manually: 
4.1) Logon SQLPLUS as user SYS and drop the sysman account and management 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; 
5) After repository deletion please recreate the repository and directory structure. 
- go to $ORACLE_HOME/bin
- at the command prompt, enter the following command:
$PROMPT> emca -config dbcontrol db -repos create
- follow the instructions on the screen 
6) In case the dbconsole startup fails please provide the files of folder
$ORACLE_HOME/cfgtoollogs
and
$ORACLE_HOME/_/sysman/log
to metalink. 
  
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 
[oracle@oracle config]$ pwd
/op/oracle/product/10.2.4/oracle_orcl/sysman/config
[oracle@oracle config]$ vi emd.properties 
把該值修改為：agentTZRegion=Asia/Chongqing 
關於時區的列表參考：10.2.0\db_1\sysman\admin\supportedtzs.lst
然後，重啟OracleDBConsole
