zOSMF Network Analyzer Performance Improvement

When importing 'large' SMF datasets with ~200m records, the zOSMF NCA Java reads all records to filter filter Type 119 records relevant. In sample this are around 2m records. This process runs for more than 4h (wasting CPU resources), which is ver...

Decrease the provisioning duration in ZOSMF's Capacity Provisioning Manager.

A 4-minute provisioning duration is to long for our mainframe. By the 4-minute mark we have already either shifted the workload balance between our mainframes or turned-on COD manually. We would like this dropped significantly.

Improvements to the ability to ascertain whether zFS filesystems are in migration

There is currently no way to check whether filesystems are in mirroring complete status but waiting for a swap operation to complete other than using the bpxwmigf command. I'd also like a new reason code issued when the user attempts to manually m...

EE over IPv6 needs to use the larger MTU of Jumbo OSAs or HiperSockets

When EE goes over IPv4 then it uses the available MTU provided by the OSAs or HiperSockets. Did you know that EE over IPv6 does not? It constrains itself to an MTU of 1100 bytes, even though OSPF is telling us the the available MTU is 8192 for Jum...

DFSMShsm Allow different numbers of backup versions and different retention criteria for Unix files within the same ZFS

The ability to use different numbers of backup versions and different retention criteria for Unix files within the same file system is required in DFSMShsm. As it is now in DFSMShsm it's not granular enough, since we require some files and/or dire...

ISPF STATS Stuck at 01.99

When a PDS/PDSE member VV.MM reaches 01.99, the stats stop incrementing and get stuck at 01.99. When 01.99 is reached can the VV be incremented to 02 and the MM be reset to 00 and continue updating up to the limit of VV.MM, then reset back to 01.0...

Enhance RACF so that type 80s cut for CONNECT commands are consistent

RACF should be consistent about when it cuts type 80 records for CONNECT commands. That is not the case today. We always get them when the AUTH() parameter is specified even if the connection already exists. We do not get them if we issue this typ...
