CAS becomes unavailable due to inactivity

Thu May 8 06:42:22 EDT 2008

Hi,I have deployed cas server 3.0.5 on tomcat 5.5.23. CAS talks to MySQL 5.0 for authentication purpose. For this I made following modification to deployerConfigContext.xml.&lt;bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;property name="driverClassName"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;value&gt;com.mysql.jdbc.Driver&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;property name="url"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;value&gt;jdbc:mysql://localhost:3306/db&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;property name="username"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;value&gt;user1&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;propert!
 y name="password"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;value&gt;user1&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;/bean&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;bean id="SearchModeSearchDatabaseAuthenticationHandler"&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; class="org.jasig.cas.adaptors.jdbc.SearchModeSearchDatabaseAuthenticationHandler"&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; abstract="false" singleton="true" lazy-init="default" autowire="default" dependency-check="default"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;property&nbsp; name="tableUsers"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &lt;value&gt;users&lt;/value&gt;&!
 nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&n
bsp; &nbsp; &lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;property name="fieldUser"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &lt;value&gt;userid&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;property name="fieldPassword"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &lt;value&gt;password&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;property name="dataSource" ref="dataSource" /&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;/bean&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nb!
 sp; &nbsp;&nbsp;&nbsp; &nbsp;The applications deployed on tomcat are then integrated with CAS by modifying their respective web.xml (s) and server.xml of tomcat. When I try to login to my application the login is successful and everything works fine. If I leave tomcat and mysql running overnight and if I again try to login to my application next day I get CAS in Unavailable error. If I restart tomcat everything works fine again. What could be the possible reason for this? What is the solution to this problem?
