TOLERATE (ENQFAILURE) and SHARE considerations z/OS DFSMStvs Administration Guide GC52-1388-00 |
|
Using TOLERATE(ENQFAILURE) modifies the processing and serialization for backup-while-open data sets. The data sets are dumped when the backup-while-open status is 100, even though none of the enqueues are successfully acquired. To maintain data integrity and data security, do not specify either SHARE or TOLERATE(ENQFAILURE) when you dump backup-while-open data sets. An exclusive enqueue on the BWODSN resource name for the data set is required for DFSMSdss to alter the backup-while-open status. DFSMSdss attempts an exclusive enqueue only on the BWODSN resource name. Unless the backup-while-open status is already 100, the dump fails, even though you specified SHARE or TOLERATE(ENQFAILURE). |
