Logical Log Configuration Disk Space
The database server uses the logical log to store a record of changes to the data since the last archive. Enterprise Replication requires the logical log to contain entire row images for updated rows, including deleted rows.
The database server normally logs only columns that have changed. This behavior is called the logical-log record reduction option. Enterprise Replication deactivates this option for tables that participate in replication. (The logical-log record reduction option remains enabled for tables that do not participate in Enterprise Replication.) Enterprise Replication logs all columns, not only the columns that have changed, which increases the size of your logical log.
To determine the size of
your logical log, examine your data activity for normal operations and for
the replication system you defined. Keep in mind that defining replication
on a table causes Enterprise Replication to deactivate log reduction for that table, and that
your transactions might log more data.
Important: Enterprise Replication performs internal cleanup tasks based on how often the log
files switch. If the log files switch too frequently, Enterprise Replication might perform excessive
cleanup work.
