Oracle Install OEM Error: Solution cannot be unlocked for all EM-related accounts

The Oracle version on this book is 11.2.0.1. OEM was not installed at the time of previous installation, and today, when installing with dbca, the error interface is as follows:

Oracle Install OEM Error: Solution cannot be unlocked for all EM-related accounts1

THERE'S BEEN A WAY TO ORGANIZE AN OEM REBUILD BEFORE:

Oracle OEM rebuild

http://www.cndba.cn/Dave/article/614

follow these steps:

1, modify DBSNMP
password: reconfigure DBCONSOLE, you need to enter DBSNMP password, but any password will show errors, need to be modified in advance.
sql>alter user dbsnmp identified by xxx;

2, delete the user created
earlier DBCONSOLE: sql > drop role MGMT_USER;
sql>drop user MGMT_VIEW cascade;
sql>drop user sysman cascade;

3, delete the objects created
by the earlier DBCONSOLE: sql>drop PUBLIC SYNONYM MGMT_TARGET_BLACKOUTS;
sql>drop public synonym SETEMVIEWUSERCONTEXT;

then rebuild with commands or dbca commands to build them all, ok.

when you execute a command, the report object does not exist and is not directly ignored.

if you use a command, here's what to do

$emca -config dbcontrol db-repos
create according to the prompt, enter
SID first, then enter Y continue; enter port 1521, enter SYS password, enter DBSNMP password, enter SYSMAN password, enter Y continue, complete.

I was too lazy to knock on the command and direct dbca to install the OEM.

Google for a moment, some netizens used the fourth method in my previous article to solve.

Option 4. DeleteDB Control Repository Objects Manually
