Hi Allan,
Thanks for your quick reply.
I have checked in OWB\Locations\Database\Oracle\Location\DB Connectors and also in Control Center\Location\Connectors,seems like there is no connectors created.
Do you have any other suggestions?
Also i analyzed the UpdateControlCenter.sql in that
select value into v_connectiontype from cmpstringpropertyvalue_v where logicalname = 'CMPLocation_ConnectionType' and propertyowner = v_elementid;
the qry returns 'SQL*NET'.
Any workaround for these???
Please reply.
