Check if the Database Control service is running by executing: ORACLE_HOME/bin/emctl status dbconsolethe output should be::5500/em/console/about Application Oracle Enterprise Manager 10g is running.------------------------------------------------------------------Logs are generated in directory /d01/oracle/product/10.2.0/db_1/hostname_sid/sysman/log If the Database Control service is not running start it with: ORACLE_HOME/bin/emctl start dbconsole To stop the Database Control service run: ORACLE_HOME/bin/emctl stop dbconsole A complete list of available commands can be obtained by just typing: ORACLE_HOME/bin/emctl - ORACLE_HOME/hostname_sid/sysman/log/emdb.nohup - contains the standard output from the Console main Java process at each start/exit (dbconsole and agent). This value needs to be set to one of the values listed in '/usr/pkg/oracle/product/10.2.0/db/sysman/admin/supportedtzs.lst'.It is appended with each new output of the Console main Java process.- ORACLE_HOME/hostname_sid/sysman/log/and - main agent log & trace files- ORACLE_HOME/hostname_sid/sysman/log/and - main management service log & trace files- ORACLE_HOME/hostname_SID/sysman/log/and - emctl log & trace files- ORACLE_HOME/hostname_SID/sysman/log/and - log and trace file for Java Fetchlets Additional information related to log files can be found under Troubleshooting steps:1. Mainly, check, ORACLE_HOME, PATH, LD_LIBRARY_PATH, LANG.2. Execute 'emctl config agent get TZ' and see if this is an appropriate value.

If the timezone does not match one of the values in ORACLE_HOME/sysman/admin/the dbcontrol agent will not start.To use the Database Control any other time the service needs to be running. When checking dbcontrol status returns: "EM Deamon is not running".'. This value might have been manually modified to be an incorrect value.
Instead of "myhost" the hostname resolves to "myhost.mydomain.com" emctl will not find: ORACLE_HOME/oc4j/j2ee/OC4J_DBConsole_myhost.mydomain.com_sid ORACLE_HOME/myhost.mydomain.com_sid To resolve the issue database control needs to be recreated using the correct hostname.Set the right value and retry the process.b) Network changes.If the hostname where Database Control was created in the first place is not resolvable anymore startup will fail with above error.One can also view performance and status information about the managed database.Database Control is by default installed if “Use Database Control for Database Management” option is used on the “Select Database Management Option” page when installing the Oracle Database Server.
