Topic: The client 10.2.0 oracle is not connected to server basis 9.0.1
Faced such problem!
There is a server on which our basis 9.0.1 is twisted.
On client places setting of a client part of basis 10.2.0 and an accounting software is produced.
At an input in WINDOWS 7 (32 bit) on client PCs with the rights of the manager all perfectly works.
If I take away the rights in WINDOWS from users connection to server basis disappears.
Thus "the access Error to DB Transaction not connected" stupidly writes!
The rights to folders on the user gave and made its owner folders.
Granted the rights to the given branch of the register (HKEY_LOCAL_MACHINE\SOFTWARE\oracle) and as made the user the owner.
But all is ineffectual even an error did not exchange.
In what side to dig at all I do not know further?
