EM dbconsole not starting and giving NET HELPMSG 3547

 

Here are the steps you can use to check if you face problems with EM DB Consle

Database version : 11.2.0.0.2 standard edition

EM DB Console not working.

1) check the status of dbconsole as follows

C:\WINDOWS\system32>emctl status dbconsole

2) Try to start the dbconsole

C:\WINDOWS\system32>emctl start dbconsole

if the dbconsole cannot be started, sometimes this problem may occur because SYSMAN and DBSNMP users are locked, so check their account status

C:\WINDOWS\system32>sqlplus / as sysdba

SQL> select username,account_status from dba_users;

USERNAME ACCOUNT_STATUS
—————————— ——————————–
OUTLN                                            OPEN
MGMT_VIEW                                 OPEN
SYS                                                   OPEN
SYSTEM                                           OPEN
DBSNMP                                         OPEN
SYSMAN                                          OPEN
DIP                                                   EXPIRED & LOCKED
ORACLE_OCM                                EXPIRED & LOCKED
APPQOSSYS                                    EXPIRED & LOCKED

so from above, its clear that both the user accounts are open

5) Check if agent is running or not

C:\WINDOWS\system32>emctl status agent

6) If the agent is not running try to start it

C:\WINDOWS\system32>emctl start agent

sometimes you get the message NET HELPMSG 2185

C:\WINDOWS\system32>NET HELPMSG 2185

The service name is invalid.
