Switch batch image copy processing to concurrent image copy processing

If the FALLBACK option is enabled, the Image Copy function switches batch image copy processing to concurrent image copy processing when exclusive authorization of the input database is not granted.

If the Image Copy function fails to obtain exclusive authorization of the database and some other transactions access the database during batch image copy processing, the Image Copy function cannot create image copies of the database. For full-function databases and HALDBs, the image copy job ends abnormally. For DEDBs, the function bypasses the area data set that is being accessed by other transactions and continues with the next area data set or database data set. If you enable the FALLBACK option, batch image copy processing is switched to concurrent image copy processing when such a condition occurs. The advantage of using this option is that you do not need to rerun the image copy job even when exclusive authorization of the database is not granted.

Specify the FALLBACK keyword to enable the FALLBACK option.
