Partitioned databases and Version Checkpoints

Veritas Storage Foundation for DB2 provides commands for creating and using Storage Checkpoints in a DB2 Universal Database (UDB) partitioned database environment as well as an Enterprise Edition (EE) environment.

DB2 UDB Enterprise Server Edition (ESE) supports data partitioning across clusters of computers with a feature called Data Partition Feature (DPF). You can install DB2 ESE with multiple partitions on a single system or you can distribute it on multiple systems.

In a partitioned database environment, Storage Checkpoints that apply to multiple partitions in an SMP environment are referred to as Version Checkpoints. Veritas Storage Foundation for DB2 supports SMP environments. It does not support MPP environments.

Veritas Storage Foundation for DB2 commands that apply to multiple partitions end with the suffix _all. For example, db2ed_ckptcreate_all creates a Version Checkpoint for a partitioned DB2 database by calling db2ed_ckptcreate on every database partition.
