sql>drop user mgmt_view cascade;
sql>drop role mgmt_user;
sql>drop user sysman cascade;
$ emca -config dbcontrol db -repos recreate
thank you for the reply
I assume i should do this through SQL plus?
anyway, now am getting new error: ORA-00020: maximum number of processes (150) exceeded
I get this error when trying to login to SQL plus, or create/configure database.
I tried deleting oracle 11g via universal installer i get message saying run the command c:\...dbhome_1\deinstall\deinstall
I don't understand Oracle totally collapsed in my laptop with no reason
start trouble shooting from the very beginning:
you are using windows, right?
check environment variable for oracle, if there are set or not, if not set, then set environment variable for oracle.
i installed Oracle 11g r2 Database..Unfortunately i have lost the host ip address and my data base control was not opening from that time... it was showing an error that page cannot be displayed... can any one help me how to recover the lost ip address or how to open my database control
