DFSMStvs configuration changes
To run DFSMStvs you need to have set up VSAM RLS already. DFSMStvs uses the locking
and buffering techniques of VSAM RLS to access the VSAM data sets. Additionally, you need
to make the following changes:
► Prepare for logging.
– Update CFRM policy to define structures for the system logger.
– Define log streams.
– Update data sets with LOG(NONE/UNDO/ALL) and LOGSTREAMID.
This is described in more detail in 7.32, “Prepare for logging” on page 433.
► Update SYS1.PARMLIB(IGDSMSxx) with DFSMStvs parameters.
For the necessary PARMLIB changes see 7.33, “Update PARMLIB with DFSMStvs
parameters” on page 436
► Ensure that DFSMStvs has RACF authorization to the log streams.
To provide logging, DFSMStvs needs RACF UPDATE authority to the log streams. See
z/OS DFSMStvs Planning and Operation Guide, SC26-7348, for more information.
► Update the SMS configuration.
Recoverable data sets must be SMS managed. Therefore, you must change your SMS
configuration to assign a storage class to those data sets. In addition, you can optionally
change your data class with BWO, LOG, and LOGSTREAMID parameters.
