Sec_Data_Origin

Description

When you access an SAP Adaptive Server Enterprise database in PowerBuilder through Open Client, Sec_Data_Origin is one of several parameters that support per-packet security for network-based security services. (For other per-packet security parameters, see the See Also section.)

Sec_Data_Origin controls whether your connection's security mechanism performs data origin stamping. When Sec_Data_Origin is set to 1, the security mechanism attaches a digital signature to each packet that verifies the packet's origin and contents.

When Sec_Data_Origin is set to 0 (the default), no data origin stamping is performed.

You must specify a value for Sec_Data_Origin 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.

Parameter

Description

value

  • 0

    (Default) Do not perform data origin stamping. You can also specify 'No' or 'False' to set this value.

  • 1

    Perform data origin stamping by attaching a digital signature to each packet that verifies the packet's origin and contents. You can also specify 'Yes' or 'True' to set this value.


Default value

Sec_Data_Origin=0

Usage

Not supported with CyberSafe Kerberos

Sec_Data_Origin is not supported if your security mechanism is CyberSafe Kerberos.

Set Release parameter

For this parameter to take effect, you must also set the Release parameter to 11 or higher to specify that your application should use the appropriate version of SAP Sybase Open Client Client-Library (CT-Lib) behavior. See the description of the Release parameter for more information.

Requirements for use

To use Sec_Data_Origin 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 the section called “Requirements for using Open Client security services” in Connecting to Your Database.

Corresponding CT-Lib connection property

Specifying a value for Sec_Data_Origin sets the corresponding SAP Sybase CT-Lib connection property named CS_SEC_DATAORIGIN.

Examples

To specify that your connection's security mechanism performs data origin stamping:

  • Database profile

    Select the Verify Packet Origin check box on the Security page in the Database Profile Setup dialog box.

  • Application

    Type the following in code:

    SQLCA.DBParm="Sec_Data_Origin=1;Release=15"
