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.
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.

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
Type the following in code:
1SQLCA.DbParameter="Sec_Data_Origin=1;Release=15"
