Use Limit log file payload (-limitLgPayload) to prevent message payload from being written to the database log file. Message payload is defined as the user name, tty name, IP address, and connection hostname in a message.

Operating system and syntax UNIX / Windows 
-limitLgPayload n
Use with Maximum value Minimum value Single-user default Multi-user default
Database Server 1 0 0 0
n
Specify if payload is included or omitted.
  • 0 — Limit payload is off; the complete contents of messages is written to the database log file.
  • 1 — Limit payload is on; payload data within a message is not written to the database log file, and is replaced with the string, "<omitted>".

All messages written to the database log file (dbname.lg), and messages that are written to both the log file and the screen, honor the -limitLgPayload setting. Messages only written to the screen, do not check the payload setting. Other log files, such as for SQL or Replication, honor the payload setting when the information written to the log file is obtained from the database connection information.

The following examples displays the difference in messages written to the database log file when -limitLgPayload is enabled and disabled.
