100% CPU usage problem: http://forums.oracle.com/forums/thread.jspa?threadID=588715&tstart=0
Solve with:
emctl stop dbconsole (or stop the OracleDBConsoleSID Windows service)
In SQLPlus:
create table mgmt_job_bad as select * from sysman.mgmt_job where job_name = ‘PROVISIONING DAEMON’;
delete from sysman.mgmt_job where job_name = ‘PROVISIONING DAEMON’;
commit;
emctl start dbconsole (or start the service)
Startup database:
Start listener: lsnrctl start
Start web console: emctl start dbconsole
Startup database in web console: https://localhost:1158/em/console/
Usefull tools:
netca (listener configuration)
dbca (database configuration), particulary usefull after changing domain name
