Sec_Mechanism

Description

When you access a Sybase 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.

NoteUsing 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.

Syntax

Sec_Mechanism='mechanism_name'

Parameter

Description

mechanism_name

The security mechanism name you want to use to establish a connection.

The security mechanism name is case sensitive. You must specify it exactly as it appears in the Open Client/Open Server Configuration utility.

Default

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.
