For OLTP applications, TMF provides:
•
All the complex operations for concurrent transactions and database consistency,
making these operations transparent to both users and application programmers.
•
Database recovery through three mechanisms:
•
Transaction backout, which recovers the database from application or
transaction failure.
•
Volume recovery, which recovers the database in the most typical recovery
situations: a disk volume or system failure.
•
File recovery, which reconstructs database files when the copy on the data
volume is not usable.
TMF performs these operations while maintaining high performance for applications.
In addition, TMF simplifies the tasks of users who develop and manage OLTP
applications.
