The IN_DB_UTIL_LOG table is used by the IN_LOGGER stored procedure to record calls to certain stored procedures as well as any exceptions that occur during execution of the IN_DB_UTIL and IN_DB_UPGRADE packages.
This table is created when the IN_DB_UTIL package is created but will also be recreated by the IN_LOGGER stored procedure if it does not exist at the time of execution.
Most of the columns in the IN_DB_UTIL_LOG table align with the IN_CONTEXT_ATTR record type.
