Release 10.1A: OpenEdge Development:
Progress 4GL Reference

LOG-THRESHOLD attribute

The file size threshold of log files. When the current log file becomes equal to or greater than the specified size, Progress renames and saves the log file and creates a new log file.

Data type: INTEGER

Access: Readable

Applies to: LOG-MANAGER system handle

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.

Progress 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, Progress renames the log file to my.000001.log before creating a new log file.

The LOG-THRESHOLD attribute corresponds to the Log Threshold (-logthreshold) startup parameter.

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

For more information about the Client Logging (-clientlog) and Number of Log Files to Keep (-numlogfiles) startup parameters, see OpenEdge Deployment: Startup Command and Parameter Reference and OpenEdge Development: Debugging and Troubleshooting .
