Access log messages are stored in a buffer. The buffer is flushed to the access log at the following times:
When the buffer is full
When the access log is rotated
When Directory Proxy Server is stopped
By default, the size of the access log buffer is 1M. However, the size of the buffer can be configured to control the frequency with which it is flushed.
The buffer is also flushed periodically, that is, every 2.5 seconds, if none of the other conditions is met.
You can configure the size of the access log buffer by setting the log-buffer-size property. For information about how to configure access log properties, see Configuring Directory Proxy Server Logs in Oracle Fusion Middleware Administration Guide for Oracle Directory Server Enterprise Edition.
