Oracle 10g Enterprise Manager

January 26, 2010 1 comment

Oracle 10g on Windows 2003 Server:

Having set the ORACLE_SID variable, I am trying to start the dbconsole using following command.

Problem 01:

emctl start dbconsole

The errors Message :

OC4J Configuration issue. c:\oracle\product\10.2.0\db_1/oc4j/j2ee/OC4J_DBConsole
_192.168.1.41_cjdb not found.


Step 01: Find the hostname of Oracle Server and set the ORACLE_HOSTNAME Environment variable

$ hostname

Run these commands For Linux:


Run these commands For Windows:

> Set

It’s good idea to drop & recreate Enterprise Manager Repository with correct listener/port

Step 02: Now configure the em Repository following way

Drop and then create em repository for single instance

emca -deconfig   dbcontrol db
emca -config     dbcontrol db

For Cluster (drop and create and RAC EM)

emca -deconfig   dbcontrol db
emca -config     dbcontrol db


emca -config dbcontrol db

To configure the enterprise manager database control for your database, issue the following commands as oracle user in Linux Platform:

[oracle@dbsrv oracle]$ export ORACLE_HOME=<ORACLE_HOME>
[oracle@dbsrv oracle]$ export ORACLE_SID=<ORACLE_SID>
[oracle@dbsrv bin]$ cd $ORACLE_HOME/bin
[oracle@dbsrv bin]$ ./emca -config dbcontrol db -repos create
Now just follow the instructions on the screen… you’ll need the SYS, DBSNMP and SYSAUX passwords.

Sometimes you already have the SYSMAN, DBSNMP and SYSAUX accounts, and the previous EMCA command can fail to create the DBConsole repository the error ORA-20001 occurs.

ORA-20001 Sysman Already Exists While Running EMCA

If the previous drop procedure fails and by checking the logs we see ORA-01031 insufficient privileges, this may be because we don’t have a password file created. Just go to $ORACLE_HOME/dbs and check if we have a file called pwd<sid>.ora. If not, create it…

[oracle@dbsrv oracle]$ cd $ORACLE_HOME/bin
[oracle@dbsrv bin]$ ./orapwd file=$ORACLE_HOME/dbs/pwd<sid>.ora password=oracle entries=5

Problem 02:

emctl status dbconsole
Unable to determine local host from URL REPOSITORY_URL=


Change the value of REPOSITORY_URL in following way




Create Database Console

To create the configuration files and repository for Database Console, run:

$ emca -config dbcontrol db -repos create

Drop Database Console

To drop (remove) the configuration files and repository for Database Console, run:

$ emca -deconfig dbcontrol db -repos drop

Recreate Database Console

To recreate the configuration files and repository for Database Console, run:

$ emca -config dbcontrol db -repos recreate

Using EMCA with Real Application Clusters

In this section, I will be using two Database Control consoles running; one on linux1 and the other on linux2. From either of these consoles, you can manage and monitor all targets in the cluster.

For information on the current cluster configuration, you can run:

$ emca -displayConfig dbcontrol –cluster 

Create Database Console

$ emca -config dbcontrol db -repos create –cluster

Drop Database Console

$ emca -deconfig dbcontrol db -repos drop -cluster

Troubleshooting EMCA

If you have any problems when running emca, check the log file under:

For Windows:
