set_data_len
Limits the amount of data displayed when DB_ENV->lock_stat_print() is called with the DB_STAT_ALL flag.
If the db_printlog or db_dump utility uses a DB_CONFIG file with this setting, it sets the the default for the amount of data displayed for each key/data item. This value may be overridden using the -D option for both utilities.
The value set here must be greater than 0. The default value is 100.
The syntax of this parameter in the DB_CONFIG file is a single line with the string set_data_len, one or more whitespace characters, and the directory name.
For example:
set_data_len 1048576
