New CAS documentation site

CAS documentation has moved over to jasig.github.io/cas, starting with CAS version 4.x. The wiki will no longer be maintained. For the most recent version of the documentation, please refer to the aforementioned link.

The following configuration provides for database-backed auditing and statistics for CAS using the Inspektr Java library. The configuration assumes there exists a bean named "dataSource" that implements javax.sql.DataSource defined somewhere in the Spring application context, e.g. deployerConfigContext.xml:

deployerConfigContext.xml
...
  <!--
  This is a c3p0 pooled data source suitable for production environments.
  The use of some sort of connection pooling (c3p0, commons-pool) is strongly recommended
  for production use.
  -->
  <bean
    id="dataSource"
    class="com.mchange.v2.c3p0.ComboPooledDataSource"
    p:driverClass="oracle.jdbc.driver.OracleDriver"
    p:jdbcUrl="${database.url}"
    p:user="${database.user}"
    p:password="${database.password}"
    p:initialPoolSize="${database.pool.minSize}"
    p:minPoolSize="${database.pool.minSize}"
    p:maxPoolSize="${database.pool.maxSize}"
    p:maxIdleTimeExcessConnections="${database.pool.maxIdleTime}"
    p:checkoutTimeout="${database.pool.maxWait}"
    p:acquireIncrement="${database.pool.acquireIncrement}"
    p:acquireRetryAttempts="${database.pool.acquireRetryAttempts}"
    p:acquireRetryDelay="${database.pool.acquireRetryDelay}"
    p:idleConnectionTestPeriod="${database.pool.idleConnectionTestPeriod}"
    p:preferredTestQuery="select 1 from dual"
  />
...

The configuration below is the suggested configuration up until CAS 3.4. In CAS 3.4, the configuration changed. See the configuration further below.

The following configuration is based on the auditTrailContext.xml file in WEB-INF/unused-spring-configuration/auditTrailContext.xml in the CAS 3.3.1 distribution WAR archive. The following configuration must be placed in an XML file in WEB-INF/spring-configuration of the WAR file deployed in your environment; a Maven WAR Overlay is a convenient way to do this in a repeatable fashion.

  Configuration file for the Inspektr package which handles auditing for Java applications.
  If enabled this should be modified to log audit and statistics information the same way
  your local applications do.  The default is currently to log to the console which is good
  for debugging/testing purposes.

Inspektr assumes the database pointed to by the JDBC data source contains tables with the schema described at http://code.google.com/p/inspektr/wiki/DatabaseTables. The following script will create these tables with reasonable indices in Oracle; modify as needed for your database platform.

Automatic Cleaning

If you're using the JdbcAuditTrailManager, you might want to automatically clean the audit log.  Here's some example code (for your auditTrailContext.xml) that cleans out entries older than 180 days.  This has been tested in CAS 3.4.10.
