RTView Enterprise 6.1.2
The syntax used in a Log4j properties file was changed completely by Apache in version 2. The sl.log4j.properties file distributed with RTView has been changed to use the version 2 syntax. If, in previous RTView versions, you customized that file or specified your own custom log4j properties file (e.g. using the "log4jprops" option), you'll need to remake those customization using the version 2 syntax.
Note that the default logging behavior has been changed: In this release by default messages are appended to the existing logs/X.log file (where X is "dataserver", or "historian", etc depending on the name of the server) until it reaches a size of 50MB. Then it is renamed to X.log.N (where N = 1 - 9) and a new empty X.log file is created. So at any time the logs directory may contain X.log (newest, up to 50MB in size), and X.log.N where N = 1 - 9, each approx 50 MB, where 1 is the oldest and 9 is the newest. Once N = 9 is reached, on the next rollover X.log.1 is deleted and each remaining X.log.N is renamed to X.log.N-1.
