RemoteOperationException: ERROR: Invalid username and/or password

Hi
Do you face this problem? When you try to start up the oracle database using EM,you are prompted to enter windows username and password.And you are sure that the username and password are correct, however this error occurs.


This is the solution:
Step1: Goto control panel -> Administrative Tool -> Local Security Settings.
       Local Policies -> User Rights Assignment -> double click on 'Log on as a batch job'


Step 2: Add the user here which you are trying accessing the OEM and click apply and OK.
Step3 : Follow the step 2 for adding user to 'Log on as a service'.


Step4: Now try to log on to OEM.
          You will get the following screen if db is down.



Hope this could help you to resolve the error.

Try these solutions:  make sure that you check "refresh after insert" and refresh after update" for the primary key column in you entity object. in the application module tab Click the Properties tab and select jbo.locking.mode. Double click the “pessimistic”value next to the property to open the field editor and type “optimistic” over the value.Press enter. if error still exist then you must set "refresh after insert" and refresh after update" as true for all attributes in the entity object another way is to execute the View Object after the commit operation to bring back updated data to ViewObject. For this we need to override the  afterCommit()  of ViewObject class as follows:                  public void afterCommit(TransactionEvent){                         executeQuery();                  ...
