Recoverability
The recoverability attribute specifies whether the file is to be recoverable or irrecoverable. This attribute applies only to files stored in CMS file pools.
When a file is recoverable, uncommitted changes are backed out as the result of an application initiated rollback. Files are recoverable unless specified otherwise using a CSL routine or the FILEATTR command.
Irrecoverable files are not rolled back if an application initiated the rollback. As many updates as possible will be committed.
BFS files are recoverable when using the CMS record file interface.
For more information on committing and rolling back changes, see the z/VM: CMS Application Development Guide.
