Hi reader,

specially after server reboot it could be that you cannot connect to your dbconsole anymore. Following reasons i detected for The Page cannot be found message after addressing the URL of the DB Console :

• The DbConsole did not start
• The DbConsole started but failed to attach to atatch to instance

Stop the dbconsole (you can do this with the emctl utility) of the instance you could not connect. Remember that every Oracle Instance has it’s own dbconsole running. With Unix as process and with Woindows OS as Service OracleDbConsole[ORACLE_SID] :

C:\TEMP>set ORACLE_SID=ISISD

C:\TEMP>emctl stop dbconsole
Oracle Enterprise Manager 10g Database Control Release 10.2.0.2.0

The OracleDBConsoleISISD service is stopping…………
The OracleDBConsoleISISD service was stopped successfully.

Now start the dbconsole again. You already set the ORACLE_SID for this.

C:\TEMP>emctl start dbconsole
Oracle Enterprise Manager 10g Database Control Release 10.2.0.2.0

Starting Oracle Enterprise Manager 10g Database Control …
The OracleDBConsoleISISD service is starting…………….
The OracleDBConsoleISISD service was started successfully.

Now you should be able to connect to your dbconsole via Browser.
