Shared DASD considerations z/OS DFSMSdss Storage Administration SC23-6868-01 |
|
Shared DASD presents volume and data set serialization problems not encountered in nonshared DASD environments. Care should be taken when you enlist data set operations if programs operating in another processor might be accessing the data sets at the same time. A data set can be dumped from one processor while being processed from another. The dumped version may be partially updated on JES2 systems. This same exposure is present on a full dump operation. |
