The server log file (Server.locale.Log) specifies the DBMS version and build number and records the activity on a server configuration. Each time you start a server configuration, the Server renames the existing log file and creates a new log file for the current server configuration session. The log file from the previous startup is renamed to include the date and time at which it was renamed (Server.locale.date.Log). For example, if you start a server configuration on November 9, 2011 at 5:22 P.M., the old Server.locale.Log file is renamed Server.en-US.2011-11- 09-17-22-59.Log, and a new Server.locale.Log file is created whose time stamp might be 11/9/2011 17:23:03.
If the locale specified for the operating system on which your server runs is not US English, you will have two server log files: one for US English and one for your locale. For example, you might have both Server.en-US.Log and Server.fr-FR.Log. The first log is for support purposes, and the second log is for your use.
Formatting of the log gives a line number, code, date and time, and message. The code numbers are not in any order of severity.
