I have a problem getting ZSybaseDA to work : any connection is rejected with the following error : Error Type: SybaseError Error Value: ['failed to connect to server', ('client', 5, 84083972, 'ct_connect(): network packet layer: internal net library error: Net-Lib protocol driver call to connect two endpoints failed', 0, 'Socket connect failed - errno 0', 0, '08001')] The problem appears when : -- opening the database connection with Zope manager screen -- executing a minimal external method which uses ctsybase module: sybtest.py: import ctsybase def OpenSybase(self): c=ctsybase.ctsybase({'user':'user','password':'password', 'server':'server'}) res=c.execute('select * from table') c.close() return `res` if __name__=="__main__": print OpenSybase(None) But *not* when : -- executing that same method directly from python -- executing it from Zope via an external method which does a popen of that script -- executing a popen of one of the sybase ct-lib samples (getsend) So, it seems the ctsybase module works ok, except when activated from Zope... My context is: OS : AIX 4.1.5 Python : 1.5.2 Zope : 2.0.1 ZSybaseDA : tried 0.9 and 1.0.1 Sybase Open-Client : 11.1.1 Any help welcome... -- Georges JEGO -- Ministère de l'agriculture et de la pêche 251 rue de Vaugirard - 75732 PARIS Cedex 15 - FRANCE Tél : 01 49 55 86 34 -- Fax : 01 49 55 86 66 Mél : georges.jego@agriculture.gouv.fr
