oradim startup service ends with ORA-24327: need explicit attach before authenticating a user

 Hi Community,

I have this problem in some databases:

Oracle 10.2 on Windows 2003 32-bit - very stable;

Oracle 10.2 on Windows 2003 64-bit - rather stable;

Oracle 11.2 on Windows 2008 64-bit - random.

Starting OracleService<ORACLE_SID> not starts the database instance, but after this I need to execute startup from SQL*Plus.

The file oradim.log in %ORACLE_HOME%\database contains error messages:

ORA-24327: need explicit attach before authenticating a user

As a result the database on such machine does not start automatically (or not always starts automatically) on server reboot. As a result on each reboot a manual intervention is required.

I faced the same problem on both real and virtual (VMvare) machines. And I cannot find any solution in My Oracle Support Knowledge Base.
