Security and Integrity Parameters

The following access method services parameters provide security and integrity information. See Protecting Data Sets for more information about the types of data protection available.

Passwords—Because passwords are not supported for system-managed data sets, this information pertains to non-system-managed data sets only. See z/OS DFSMS Access Method Services Commands.
AUTHORIZATION parameter—Specifies your own authorization routine to verify that a requester has the right to gain access to data.
EXCEPTIONEXIT parameter—Specifies an I/O error-handling routine (the exception exit routine) that is entered if the program does not specify a SYNAD exit. See Coding VSAM User-Written Exit Routines for information about VSAM user-written exit routines.
WRITECHECK parameter—Specifies whether to verify that write operations have completed and that the data can be read.
SHAREOPTIONS parameter—Specifies whether and to what extent data is to be shared among systems, and jobs.
ERASE parameter—Specifies whether to erase the information a data set contains when you delete the data set.
To control the erasure of data in a VSAM component whose cluster is RACF protected and cataloged, you can use an ERASE attribute in a generic or discrete profile. For information about specifying and using the ERASE option, see Erasing DASD Data and Generic and Discrete Profiles for VSAM Data Sets.

Restriction :

Defining a new KEYRANGE data set is no longer supported. For more information about converting key-range data sets, see the z/OS DFSMShsm Implementation and Customization Guide.
