Returns the next available
OraDatabase object from the pool.
The arguments for the method are:
||The number of milliseconds this call waits for an object to be available, if the pool contains the maximum number of objects and all are used.|
To retrieve an
OraDatabase object from the pool, the
GetDatabaseFromPool method is called. This function returns a reference to an
OraDatabase object. If the pool does not contain the maximum number of objects allowed, and all objects in the pool are used, then an additional
OraDatabase object is created implicitly. In addition, if a pool item contains an
OraDatabase object that has been timed out, then a new object is created and returned. The
OraDatabase object obtained from the pool is then marked as in use and is returned to the pool when the object is no longer referenced by the application.
Exceptions are raised by this call if:
The connection pool does not exist.
The pool contains no objects.
A time-out has occurred.
LastServerErr property of the
OraSession object contains the code for the specific cause of the exception.
