Internal Error in reading a Table of Oracle custom-defined objects.

Question

Hi,
We are running into an Oracle internal error when trying to extract data from an OUT parameter of a stored procedure. The OUT parameter is of the type TABLE of Oracle custom-defined OBJECT.
Any help on this issue will be greatly appreciated.
Thanks, in advance,

hi Thom,
most error relating to table DOKTL are caused by misconfigured network card.
if this is a "home" system, install a loopback adapter from Microsoft and use IP address 127.0.0.1 and also check "hosts" file for inconsistency. do not use the IP adddress provided by your ISP as it may change.
