In a distributed installation, you can configure the log server on each Cognos 8 computer to send log messages to a single remote log server, which acts as a common log server. You can then configure the common log server to send the log messages to a local file or database on the same or another computer.
If the remote log server becomes unavailable, log messages are redirected to recovery files on the local computer in the c8_location\logs\recovery\remote directory. These recovery files have timestamp information in their file names, and are not readable like regular log files. When the remote log server becomes available, an automatic recovery process moves all log information to the remote log server and deletes the local log files.
