Provide encrypting find/file databases similar to z/TPFDF encryption

As PCI, PII, and GDPR requirements become more and more stringent, it will be as important to encrypt traditional Find/File databases as much as z/TPFDF databases. IBM already provides the built-in ability to encrypt/decrypt through database defin...

Allow High-Speed Connector to function in CRAS state or above

RTMC uses the high-speed connector to send data to the off-host Linux listener. Since RTMC is the new way to send performance data, and eventually user data, we do have a need to know what the system is doing in all states.

RTMC - Grafana links for orgID != 1

The RTMC starter kit dashboards provide internal links that reference orgID=1. This appears to be the default Grafana organization. When multiple organizations are defined in Grafana this may lead to 404 errors when navigating through dashboards. ...

Enhancing RTMC NVP collection in tpfrtmc to extract a configurable sample of the received ECB data would enable examination of the underlying distributions for better insights that simple averages would hide.

During RTMC NVP collection the tpfrtmc component could extract a configurable sample of the received ECB data, which would include the following: ECB lifetime CPU burn time Finds Files Etc. This would enable examination of the underlying distribut...

ECB Heap Statistics

We found a way to get ECB Heap statistics from the ECB Heap Control Table (EHTC). This requires minor changes to CLHH (CCSTOR) and CMALOC (CTIS). We would like the lab to consider adopting this change. At exit time, looping through EHCT Entries, w...
