To enable tracing for a specific component in SailPoint IdentityIQ, administrators must modify the Log4j configuration.

1. Locate the File: The primary logging configuration file for IdentityIQ is log4j.properties (or log4j2.properties in versions 8.0+), located in the WEB-INF/classes directory.
2. Enable the Logger: The specific logger for Certifications (often referred to internally or in older versions/exams as Certificationer) is commented out by default. Removing the # activates it.
3. Set Level: The default level in the provided line is info. The question requires trace, so the value must be manually updated.
4. Apply Changes: While dynamic reloading is possible via the Debug pages, the standard system-level procedure to ensure all property changes (especially in the classpath) take full effect is to restart the application server (e.g., Tomcat).

SailPoint IdentityIQ Administration Guide / System Administrator Guide: Section on "Logging" or "System Monitoring," which details the location of log4j.properties in WEB-INF/classes.

SailPoint Compass Community (Official Knowledge Base): "How to find Log4j.properties and IdentityIQ logs" (Article ID: TA-P/72506). This article confirms the path WEB-INF/classes/log4j.properties.

Apache Log4j Documentation: Verifies that standard .properties files for web applications are placed in WEB-INF/classes for the classloader to find them.

SailPoint Developer Community: Discussion threads (e.g., "Certification is showing pending") often cite enabling sailpoint.api.Certificationer to trace for troubleshooting certification generation issues.
