Log tables

The following Pega Platform database tables can store instances of Log- classes. For example, the pr_changelog table holds instances of the concrete classes derived from Log-System-. They record schema changes made using the Property Optimization tool and the Modify Schema tab.

The key to these instances contains a date and time in UTC format.

The Pega-RULES agent normally runs the standard Code-.SystemCleaner activity once each day for housekeeping tasks, including purging older records (instances) from certain log tables.
