SYSCOPY
Use this option to instruct BMC AMI Unload to unload from an image copy data set, obtaining the data set name from SYSIBM.SYSCOPY.
If you specify a single partition number, BMC AMI Unload searches only for the indicated partition. Otherwise, BMC AMI Unload performs the search with DSNUM=0.
You can specify one of the following suboptions:
FULL | (default) Obtains the full image copy data set that has the highest START_RBA |
---|---|
INCR | Obtains the incremental image copy data set that has the highest START_RBA |
LAST | Obtains the image copy data set that has the highest START_RBA This data set can be incremental or full. |
The following considerations apply to the SYSCOPY option:
- When unloading from an image copy, you cannot specify multiple partitions with the PARTS option.
- If you specify the SYSCOPY option, you cannot specify COPYDDN or COPYDSN.
- Do not use MODE(DB2SQL) or MODE(AUTO) with this option.
- Does not support Cabinet copies.
Partitioned table spaces
For a partitioned table space:
- BMC AMI Unload uses the latest full copy to complete unload procesing.
- If the latest copy is a DSNUM 0 copy, BMC AMI Unload uses a copy of the entire partitioned table space.
If no full copy exists, BMC AMI Unload dynamically allocates and uses the partition-level copies provided that:
- Every partition has a copy.
- Each copy has the same START_RBA value.
If these conditions are not met, the unload job fails.
If the table space is partitioned, BMC AMI Unload uses individual partition image copies (DSNUM does not equal 0). If not every partition that you unload has a copy, BMC AMI Unload uses the first image copy that fulfills your specifications and that contains all partitions (DSNUM equals 0).
