The maximum size, in 1K blocks, of the Replication Agent system log file before wrapping.
The value of the log_wrap parameter is the number of 1KB blocks written by Replication Agent, before it wraps the system log file.
Larger values for the log_wrap parameter allow more log history in each file. Smaller values produce smaller log files.
When the log file wraps, Replication Agent copies the current log file to a backup file, with a generated number appended to the file name.
For example, if the system log file is named my_ra.log, the first backup file created when the system log wraps would be named my_ra1.log. The second backup file created would be named my_ra2.log, and so on.
When the number of backup files exceeds the value of the log_backup_files parameter, the oldest backup file (that is, the one with the lowest generated number) is deleted from the log directory before the next backup file is created.
