Sec_Sess_Timeout – PB Docs 126

Sec_Sess_Timeout database parameter


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

Some security mechanisms allow applications to set session
timeout values for connections using network-based login authentication.
For these connections, Sec_Sess_Timeout specifies
the number of seconds remaining before a session expires. The session
timeout period begins when the connection is opened.

By default, Sec_Sess_Timeout specifies that
there is no session timeout limit; the session does not expire.
You must specify a value for Sec_Sess_Timeout before connecting
to the database in PowerBuilder.

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.


  • ASE, SYC SAP Adaptive
    Server Enterprise





Specifies the number of seconds remaining
before a session expires. You can also specify 'no_limit' (the
default) to indicate that the session does not expire.

A session timeout value set by the security system’s
administrator supersedes any value you specify for Sec_Sess_Timeout.




CyberSafe Kerberos

If your security mechanism is CyberSafe Kerberos, Sec_Sess_Timeout
cannot override the installation default value set for session timeout.

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_Sess_Timeout 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_Sess_Timeout
sets the corresponding Sybase CT-Lib connection property named CS_SEC_SESSTIMEOUT.


To specify 14,400 seconds (4 hours) remaining before
a session expires:

  • Database profile

    Type 14400 in the Session
    Timeout box on the Security page in the Database Profile Setup dialog

  • Application

    Type the following in code:
