Sec_Mechanism
database parameter
Description
When you access an SAP Adaptive Server Enterprise database in
PowerBuilder through Open Client, Sec_Mechanism is one of several
parameters that support login authentication for network-based security
services. (For other login authentication parameters, see the See Also
section.)
When you use Open Client security services, you must specify the
name of the security mechanism you want to use in the Open Client/Open
Server Configuration utility so that the required drivers can be loaded.
The default security mechanism is the one currently specified as active
in the Configuration utility.
Sec_Mechanism lets you specify a security mechanism name listed in
the Open Client/Open Server Configuration utility other than the default
(active) mechanism.
You must specify a value for Sec_Mechanism before connecting to
the database in PowerBuilder.
Using third-party security mechanisms
For information about the third-party security mechanisms and
operating system platforms that has been tested with Open Client
security services, see the Open Client documentation.
