Day of week and Day of month support for ZSTIM

The TPF ZSTIM table should support additional functionality like "specific day of the week" or "specific day of the month". This was not that hard to implement and improves the capabilities of TPF's scheduler.

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...

(TPFUG) Add OSA input list monitoring

To identify / understand the bursting nature of the OSA input list, we would like a mechanism to monitor the queue specifically at high TCPIP volume rates. Sending this information to CDC RTMC is a potential solution.

Add timestamp offset for ZMATC data

PJ46868 added a timestamp offset for ZRTMC data delivered from TPF to linux. This RFE requests the same functionality for the ZMATC data. This would allow for consistent data timestamps for any TPF system that has a non-UTC system time in RTMC and...

Alternative MAXDUMPT control for manual dumps

MAXDUMPT introduced by PJ46025 does not apply to catastrophic dumps but does apply to manual dumps. Taking manual dumps is usually a planned activity and likely the content is required/or possibly required.We would be told if a manual dump was tru...

(TPFUG) Stop counting HSC closed by remote server as an error or provide a separate counter.

Today if a HSC endpoint is using persistent SSL sockets, and the remote server closes the socket it can cause the error count to be incremented. This is noticeable when the remote system implements an inactivity timeout on the socket, and there is...

z/TPF Geographically Dispersed Processing for High Availability

Multiple z/TPF Customers; Citibank, SABRE, Marriott, Amex, and TVPT, desire an implementation of z/TPF where at least two geographically dispersed z/TPF Loosely Coupled Computing Cluster (LCCC) Systems may cooperatively process against the same da...

Enhanced eventing API

Customer is looking for z/TPF to be enhanced to support some sort of external interface that allows the current ECB to exceed MAXEVENTS.  Conceptually, the current ECB should be able to call some restricted external API that gives it the priv...

(TPFUG/Visa) Provide a ZBOST STOP ISTREAM option that collapses all boosted i-streams

ZBOST STOP ISTREAM says it stops I-Stream Boost but it just immediately collapses the highest boosted i-stream number and sets the timer for the next to collapse in 1 minute. We need an option that will collapse all boosted i/streams to the CAP va...

Add more information to ZSSLD DIS command for better diagnostics

Please add to the existing display information regarding the allocation of CTXes to each daemon, what daemons are supporting what ports, and a high-water mark for CTXes on each daemon. It also might be useful to display the timestamp of the oldest...
