Manual file rotation and forced log rotation do not apply to Directory Proxy Server.
If you do not want to define automatic creation and deletion policies for Directory Server, you can create and delete log files manually. In addition, Directory Server provides a task that enables you to rotate any log immediately, regardless of the defined creation policy. This functionality might be useful if, for example, an event occurs that needs to be examined in more detail. The immediate rotation function causes the server to create a new log file. The previous file can therefore be examined without the server appending logs to this file.
For information about how to rotate logs manually and how to force log rotation, see Rotating Directory Server Logs Manually in Oracle Fusion Middleware Administration Guide for Oracle Directory Server Enterprise Edition.
