n

A log file size threshold in bytes.

When the current log file becomes equal to or greater than the specified size, OpenEdge renames and saves the log file and creates a new log file.

Valid values are:

0 — This means there is no limit other than what the operating system imposes. Specify 0 to ignore the Number of Log Files to Keep (-numlogfiles) startup parameter setting. This is the default.
Between 500,000 and 2,147,483,647 — Values are in bytes (one byte typically holds one character). You can specify a file size up to 2GB, inclusive, but not lower than 500,000.

If you specify a number lower than 500,000, a run-time error occurs and the OpenEdge process terminates.

OpenEdge names log files based on a sequence number using the following format:

<filename>.999999.<extension>

For example, if you specify a log file named my.log, OpenEdge renames the log file to my.000001.log before creating a new log file.

Use the Client Logging (-clientlog) startup parameter to specify a log file name for 4GL clients. Use the Number of Log Files to Keep (-numlogfiles) startup parameter to specify the number of log files to keep.

You can also can use the LOG-THRESHOLD attribute on the LOG-MANAGER system handle to specify the file size threshold of log files. For more information, see the OpenEdge Development: Progress 4GL Reference .
