Sec_Data_Origin – PB Docs 126

Sec_Data_Origin database parameter

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.

Syntax

Parameter

Description

value

Specifies whether your connection’s
security mechanism performs data origin stamping. Values are:

  • 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

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 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_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 “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 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
