For Example:A, B.quest.com =
  (DESCRIPTION =
      (ADDRESS =(PROTOCOL = TCP)(HOST = x)(PORT = 1522))
    (CONNECT_DATA =(SID = z)))

C, D =
  (DESCRIPTION =
      (ADDRESS =(PROTOCOL = TCP)(HOST = x)(PORT = 1522))
    (CONNECT_DATA =(SID = z)))

WORKAROUND:
None

STATUS:
Waiting for fix in a future release of Toad Data Point.
