CREATE PUBLIC SYNONYM MGMT_AVAILABILITY FOR MGMT_AVAILABILITY
*
ERROR at line 1:
ORA-00955: name is already used by an existing object

Cause

Related Bug 6111734  EMCA THROWS CONFIG: ORA-00955 CREATE PUBLIC SYNONYM MGMT_AVAILABILITY FOR MGMT_A


Solution

As a workaround,

Drop the Repository using RepManager


<ORACLE_HOME>/sysman/admin/emdrep/bin/RepManager <hostname> <listener_port> <sid> -action drop

Note : This will not remove the configuration files, but only the repository related objects from the database.Also, the database will be put in Quiescing mode when RepManager is ran.
Refer Note 375946.1 Running EMCA Results in Database quiesce And No New Connections or Operations Can Be Performed During the DB Control Repository Creation

If above RepManager fails with conflicts for any other SYNONYM then manually drop the DBConsole repository and objects referring to Note 278100.1 How To Drop, Create And Recreate DB Control In A 10g Database
