Solution for Oracle em can't log on after computer IP changes (pro-test)

The following methods for my pro-test

Scenario: Assume that the first time the computer installed Oracle IP is 192.168.133.110

Then the address to the EM is Http://192.168.133.110:1158/em/console/logon/logon.

Suppose the computer's IP is changed to 192.168.88.66

Then the address into EM should be http://192.168.88.66:1158/em/console/logon/logon.

But after the test, enter the above address can not enter EM, because the computer IP has changed, Oracle needs to modify the configuration file can be accessed, after the general modification of the configuration file, there will be ORACLEDBCONSOLEORCL can not start the problem.

Method One, not successful, or not into the EM

Reach the D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN directory below

Modify Listener and TNSNames

Change host to the IP address of your local computer

Method Two, unsuccessful, or display oracledbconsole is not running

Command line input emctl start dbconsole
Displays environment variable ORACLE_SID not defined. Please define it.
Then set the ORACLE_SID according to its instructions
Enter set ORACLE_SID=ORCL on the command line (if your SID is not ORCL, please replace it yourself)
Re-typing emctl start dbconsole
Displays the oc4j Configuration issue. D:\ORACLE\PRODUCT\10.2.0\DB_1/OC4J/J2EE/OC4J_DBCONSOLE_192.168.1.101_ORCL not found.
So I went to the directory where I found a directory of my "Oc4j_dbconsole_" + machine name + "_ORCL"
Online people say if you have changed the name of the machine, then you are here to replace your new machine name with the original machine name
Turn "Oc4j_dbconsole_" + New machine name + "_ORCL"
If you are like me, it is because of environmental changes that this problem occurs, I recommend you copy a directory, make changes.
Copy "Oc4j_dbconsole_" + machine name + "_ORCL" renamed to "Oc4j_dbconsole_ 192.168.1.101_ORCL
Re-typing emctl start dbconsole
There are display em Configuration issue. d:\oracle\product\10.2.0\db_1/192.168.1.101 _ORCL not found
I think you know how to do it.
Copy to the appropriate directory, duplicate a rename
Re-typing emctl start dbconsole

Method Three, the simplest way is to rebuild EM, success, pro-Test

CMD into command line

C:\Documents and Settings\administrator>set ORACLE_SID=ORCL

C:\Documents and Settings\administrator>emctl status Dbconsole

Tip Oracle Enterprise Manager 10g is not running

Well, it looks like Dbconsole's not up, go ahead.

Emctl Start Dbconsole

Found that ORACLEDBCONSLEORCL could not be started.

It's really not going to get up.

Go to the service for an interview. Run->services.msc, start the ORACLEDBCONSLEORCL service, and the results prompt the ORACLEDBCONSLEORCL service to start and close. It seems that still can not get up, do not know which classmate in the database server has done something, may be changed IP? Changed the machine name? Or what? I don't care anymore, solve the problem. Think about it, re-create EM.

Back to Windows command line execution

C:\Documents Andsettings\administrator>emctl Startdbconsole

Okay, the console service is up,

OEMs can also log in normally.

Note: The password for the dbsnmp user appears during the period: I did not set the user's password when I installed Oracle

However, you can use the SYS user to modify the user's password to the password you want to set.

Methods are as follows

Sql> Conn sys/a as Sysdba

sql> alter user DBSNMP identified by your password.

Modify your new password
