Hi, I have built the DCOracle on a Windows NT box and I can use it from python(I have tested connect, select, update). But it doesn't work with Zope 2. When I try to open the connection my Zope terminates with an unhandled software exception, if I try to use manage_open_connection method in the monitor client I get this traceback(the real connect string is replaced with *): ------ 1999-09-07T12:11:01 PROBLEM(100) ZServer BadRequest <strong>Invalid connection string: </strong><CODE>***/***@***</CODE><br> <!-- OracleError (6413, 'ORA-06413: Connection not open.\012') --> [D:\TestSite\ZServer\medusa\monitor.py|found_terminator|94] [<secure_monitor_channel connected 127.0.0.1:1850 at c02210>|?|0] [D:\TestSite\lib\python\Shared\DC \ZRDB\Connection.py|manage_open_connection|179] [D:\TestSite\lib\python\Shared\DC\ZRDB\Connection.py|connect|197] [D:\TestSite\lib\python\Products\ZOracleDA\db. py|__init__|122] [ocidb.py|__init__|69] Traceback (innermost last): File "D:\TestSite\ZServer\medusa\monitor.py", line 94, in found_terminator result = eval (co, self.local_env) File "<secure_monitor_channel connected 127.0.0.1:1850 at c02210>", line 0, in ?
