How to configure the TIBCO Spotfire Web Player Keep Alive Service when the TIBCO Spotfire Web Player is configured for Kerberos authentication.
The default setting for IIS is to shut down the web application if there has not been a connection to it in the last 20 minutes. This behavior prevents the Scheduled Updates from running their tasks and keeping the specified analysis files instantiated in memory. To avoid this, the "TIBCO Spotfire Web Player Keep Alive Service" is a windows service which will read the configuration file and ping the Spotfire Web Player to make sure that IIS is running during the periods configured in the schedules.
This article explains how to configure the TIBCO Spotfire Web Player Keep Alive Service when the TIBCO Spotfire Web Player is configured for Kerberos authentication.
1) Configure the KeepAlive service without a Windows username and password in the configuration file (C:\Program Files\TIBCO\Spotfire Web Player\7.0.0\webroot\bin\Tools\Spotfire.Dxp.Web.KeepAlive.exe.config).
<setting name="WindowsUserName" serializeAs="String"> <value></value> </setting> <setting name="WindowsPassword" serializeAs="String"> <value></value> </setting>2) Open the properties window of 'TIBCO Spotfire Web Player Keep Alive Service' by right clicking on this server in Windows Services.
3) In the service properties dialog, on the 'Log On' tab, change the 'Logon' user to the service account that you are running the TIBCO Spotfire Web Player Application Pool as (seen here: IIS > Connections > Application Pools > "TIBCO Spotfire Web Player 7.0.0 Pool" > Advanced Settings > Process Model > Identity ).
4) Restart the TIBCO Spotfire Web Player Keep Alive Service. Doc: TIBCO Spotfire® Web Player 7.0 Installation and Configuration Manual > 6.6.1.3 Configure and Start the Keep Alive Service
