we can configure Oracle Enterprise Manager10g to monitor and
manage our database and ther are two ways to do it :
1- we can centrally manage all our databases from a single management console by usin the Oracle Enterprise Manager Grid Controle if the Management Agent is installed on the database server, or
2- we can manage each database individually by using Oracle Enterprise Manager Database Controle.
and in the two ways we must start magemant agent
* for the first one we use /u01/app/oracle/product/10.0.1/bin> emctl start agent
* for the second we use /u01/app/oracle/product/10.0.1/bin> emctl start dbconsole
where is my problem,so
the problem : * I can 't understand the difference between the two ways, and with the existe of the Grid Controle, whay we have need to the second ways?
thank you,
