If automatic log truncation is disabled, you
must periodically truncate the Replication Agent transaction log
manually.
To manually truncate the transaction log:
See the Replication Agent Reference Manual for
more information about the pdb_truncate_xlog command.
Note: As an alternative to the Replication Agent automatic
log truncation feature, use a scheduler utility to execute the pdb_truncate_xlog command
in a script.
