Sync CryptoExpress clock to sysplex timer

Currently the only way to set the clock on CryptoExpress hardware is to use the TKE workstation to manually set the time. This can result in: Discrepancy between different cryptographic hardware, especially when using multiple mainframe footprints...

Please add ACME Client feature for automatic Certificate Generation

Most if not all companies no longer allow Self-Signed Certs on their network. Most if not all organizations are requiring 90 day, 180 day or 365 Day certificate renewals. On the Z HMC this is a cumbersome task .. especially for 90 day cert renewal...

Increase the CRL field length in TR34 ICSF services

The CRL field length in TR34 ICSF services CSNDT34B and CSNDT34D are defined with only 3500 bytes. If the CA sends a CRL more than 3500 bytes then the services will fail resulting in ATMs going out of service.

NEW!! SubGroup / SuperGroups for LPAR Controls and capping

We have found a need to control different groups under a common cap for a mainframe server. We would like the ability to have test systems with lesser priorities set to a subset value of a larger cap controlling all LPARs (including test) in this ...

Dynamic HW activation support for LinuxONE III

JPMC has purchased three LinuxONE III machines to use for IDAA SSC. This will be part of their zOS IODF. They have asked if they would be able to perform dynamic activations on this machine like they could for their standalone coupling facilities.

Crypto ID in toggle on/off panel

When isolating a crypto engine we have to verify the crypto deactivated in ICSF with the crypto engine on the toggle off/on panel. It would be beneficial if we could verify the serial number from ICSF with the toggle off/on panel before taking the...

Retrieve/update Authorized LPARS that can send commands via BCPII

As service provider hosting lot of customers, defining the LPARs that can send BCPII command to an LPAR and retrieving this information are fastidious manual operations. Would be nice if we could perform it via a batch program
