As with the database, you must extend the recovery log once you have defined a
new volume. Example 5-4 shows how to extend the recovery log using the extend
log command.

Notice that an ANR0307I message is printed for every 4 megabytes of the log
volume that is formatted. After the assigned capacity is extended, the output from
query log changes accordingly. As we have extended the log to use all the
defined volumes, the maximum extension column shows 0 bytes.
5.3 Setting the log mode
Use the set logmode command to set the mode for saving recovery log records.
The log mode determines how Tivoli Storage Manager saves records in the
recovery log and controls the kind of database recovery you can use. The two log
modes are NORMAL and ROLLFORWARD.
NORMAL
In normal mode, Tivoli Storage Manager saves only those transactions
needed to restore the database to the point of the last database backup.
Tivoli Storage Manager deletes any unnecessary transactions from the
