syncMode

Data type: db2ACS_SyncMode.

The level of synchronization between the backup operations on separate database partitions.

Values:

DB2ACS_SYNC_NONE

No synchronization between related operations on multiple database partitions. Used during operations which do not make use of any synchronization between the multiple database partitions.

DB2ACS_SYNC_SERIAL

Used when performing concurrent snapshot backup operations on multiple database partitions. Each database partition will have its input and output (IO) suspended when the snapshot backup operation is issued, and then the IO on the database partitions is resumed serially, not concurrently.

DB2ACS_SYNC_PARALLEL

Performing a snapshot operation on multiple partitions concurrently. Once all database partitions that are involved in the snapshot backup operation have completed preparations for the snapshot backup operation, input and output (IO) will be suspended on all of the database partitions. The remaining snapshot backup steps will take place concurrently on all of the involved database partitions.

dbPartitionList

Data type: db2ACS_PartitionList *.

db2ACS_PartitionList contains information about the database partitions that are in the database and that are involved in a Db2 ACS operation.
