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 Sybase has tested
with Open Client security services, see the Open Client documentation.

The default value for Sec_Mechanism is the security
mechanism name currently specified as active in the Open Client/Open
Server Configuration utility. If there is no security mechanism
specified, no security service is used to establish the connection.
Usage
When to use
Set Sec_Mechanism to use a security mechanism specified
in the Open Client/Open Server Configuration utility other
than the default (active) security mechanism. For instructions
on using the Open Client/Open Server Configuration utility,
see your Sybase Open Client/Server configuration guide.
Set Release parameter
For this parameter to take effect, you must also
set the Release parameter to 11or higher to specify that your application
should use the appropriate version of Sybase Open Client Client–Library
(CT-Lib) behavior. See the description of the Release parameter
for more information.
Requirements for use
To use Sec_Mechanism or any other parameter supporting
Open Client security services, you must meet certain requirements for
using security services in your PowerBuilder application. For details,
see “Requirements for using Open Client security services” in Connecting
to Your Database.
Corresponding CT-Lib connection property
Specifying a value for Sec_Mechanism sets the corresponding
Sybase CT-Lib connection property named CS_SEC_MECHANISM.
