What this error is?
SQL> DESC DBA_TABLESPACES;
ORA-24372: invalid object for describe
Here is the error description
ORA-24372 invalid object for describe
Cause: The object to be described is not valid. It either has compilation or
Action: The object to be described must be valid.
I am trying to run form6i. When I used Datablock Wizard
to enter the table name, I am getting ORA-12154: TNS: could
not resolve service name.
Could any one tell me why I am getting this error and how
to resolve this.
