Reducing the impact of transaction failure

Transaction failure is the premature termination of transaction processing before transactions can be committed to the database, which might result in data loss or corruption.

To reduce the impact of a transaction failure, try to ensure:

An uninterrupted power supply for each Db2® server
Adequate disk space for database logs on all database partitions
Reliable communication links among the database partition servers in a partitioned database environment
Synchronization of the system clocks in a partitioned database environment.
