When you access a Sybase 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.
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.
ASE, SYC Sybase Adaptive Server Enterprise
Sec_Sess_Timeout=value
Parameter |
Description |
|---|---|
value |
Specifies the number of seconds remaining
before a session expires. You can also specify A session timeout value set by the security system's administrator supersedes any value you specify for Sec_Sess_Timeout. |
Sec_Sess_Timeout='no_limit'
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
box.
Application Type the following in code:
SQLCA.DBParm="Sec_Sess_Timeout=14400"
