The error is because the table already exists in the database.

When we install the product, all the tables will be created in the database. Post installation when Registry starts it will again check for some of the tables and try to create it again. This error message is because of that.  





When you restart the Registry Service,  we check to see for all the Tables,  and will try to create it again.    "ORA-00955: name is already used by an existing object"  message we saw in the logs is  just a DBUG Warning message.  This can be ignored. 

when this happens

1. we stopped all the Services,  Portal , VSE , REgistry  , ED and IAM 

2. Cleared all the logs in  CA/DevTest/lisatmp10.6 folder. 

3. Restarted the services - IAM, ED, Registry , Portal and VSE.
