DFSMS DSS

DFSMSdss DUMP/Restore MSS>=1

Because of address contraint (one SYSPLEX) we are using multiple MSS. We are using MSS 0 for MetroMirror (aka PPRC) primary devices.We are using MSS 1 for MetroMirror (aka PPRC) secondary devices. We are planning to do consistent Flashcopy for all...

Optimized ADRDSSU CPU usage for uncompressed Striped Datasets backup

WHEN CALLING ADRDSSU TO DUMP A non-compressed SEQUENTIAL DATASET TO TAPE THE AMOUNT OF CPU FOR PROCESSING A 16 STRIPE DATASET WITH OPT(4) IS APPROXIMATELY 500-700% OF THE CPU USED TO DUMP THE SAME DATA FROM A NON-STRIPED OR SINGLE STRIPED DATASET ...

Provide a mechanism to prevent the use of Flash Copy if Preserve Mirror Required is not also specified

In a GDSP Metro Mirror configuration, recoverability it broken if a Flash Copy is initiated without Preserve Mirror being invoked. I believe, in this configuration, it is better for a Flash Copy to fail if Preserve Mirror is not performed. What is...

Require DFSMS DSS to provide detailed messages about the encryption status of data sent to the cloud, and also to enquire on crypto status of cloud-resident data.

Any enterprise sending data to the cloud must be confident the data sent is encrypted at the target and on the wire with customer keys and not just the provider keys. Messages should be issued displaying the status. In addition a query command nee...

Add advanced encryption algorithms for DUMP/RESTORE

Right now, DFSMS DSS dump/restore support the following encryption algorithms. CLRTDES - This option specifies that the dumped data is encrypted with a clear triple-length DES key. CLRAES128 - This option specifies that the dumped data is encrypte...

Restore a pre allocated file and change the mgmgtclas

During restore of a file, if i want to change the mgmtclas, i need to delete the file to have the wanted mgmtclas by sysin DSS job (keyword mgmtclas). If the file already exist, i code REPLACE keyword but the mgmtclass is unchanged, MGMTCLAS remai...

DSS should support more entries in list (Msg ADR137E applies)

DSS issues message ADR137E when more than 255 entries are specified in an inline INCLUDE list (and EXCLUDE list). Specify more than this and you need extra work to add a FILTERDD or use more than one DUMP command. This seems to be a completely arb...

Be able to enforce use of FCTOPPRCPRIMARY(PRESMIRREQ) when FASTREPLICATION(PREF) or FASTREPLICATION(REQ) is specified

In a GDPS Metro Mirror environment, use of FASTREPLICATION can lead to devices going into duplex pending state, causing the system to be unable to perform a hyperswap. When FASTREPLICATION(REQ) or FASTREPLICATION(PREF) is in place (either specifie...

DSS should support all functions for the cloud too

Within HSM I recognized that DSS is not migrating some datasets to the cloud because of its limitations. In my case: ADR600E, RC=7, The data set is a VSAM data set where the high used RBA equals the high allocated HBA. First I thought it's an erro...

ADRDSSU move multivolume file to new SMS volumes preserving original allocation

I would like to have the capability to use DFDSS to move a multivolume file from one SMS pool to another and do not consolidate or manipulate the allocation. If I have a 4 volume file when moved I would like the target to be on four volumes regard...
