SUF (also known as XBM) considerations
If you have installed the required version of
SUF
(also known as
XBM
), LOADPLUS can use the following
SUF
(also known as
XBM
) functions:
- Instant Snapshot functionality for a LOAD RESUME YES SHRLEVEL REFERENCE job
- Software snapshot functionality for referential constraint checking
- zIIP processing
SUF (also known as XBM) are licensed, installed, and maintained separately from LOADPLUS. You can use either SUF (also known as XBM), depending on the license that you have obtained:
- A license for the full version of the SUF (also known as XBM) product authorizes you to use all SUF (also known as XBM) features.
- A license for SUF (also known as XBM) authorizes you to use only the snapshot and zIIP-processing features of SUF (also known as XBM).
For more information, see the SNAPSHOT UPGRADE FEATURE for DB2 documentation..
Considerations for using SUF (also known as XBM) with LOAD RESUME YES SHRLEVEL REFERENCE
When performing a LOAD RESUME YES SHRLEVEL REFERENCE load, LOADPLUS uses the Instant Snapshot functionality of SUF (also known as XBM) to create a consistent copy of the participating table space or partitions. LOADPLUS uses this copy as the staging data set for the load process.
For more information, including the procedure and requirements for running this type of load job, see Running-SHRLEVEL-REFERENCE.
Considerations for using SUF (also known as XBM) to enforce referential constraints
LOADPLUS uses the software snapshot functionality of SUF (also known as XBM) to make a consistent image of the primary indexes on the parent table of the table that you are loading, without making those indexes unavailable.
If you do not have an appropriate version of SUF (also known as XBM) installed and available to LOADPLUS, specifying ENFORCE RI or ENFORCE CONSTRAINTS causes LOADPLUS to terminate.
