Application Programming Interface (API) to automate

STP CTN reconfiguration: The concept of “a pair and a spare” has been around since the original Sysplex Couple Data Sets (CDSs). If the primary CDS becomes unavailable, the backup CDS would take over. Many sites have had automation routines bring a new backup CDS online to avoid a single point of failure. This idea is being extended to STP. With this enhancement, if the PTS fails and the BTS takes over as CTS, an API is now available on the HMC so you can automate the reassignment of the PTS, BTS, and Arbiter roles. This can improve availability by avoiding a single point of failure after the BTS has taken over as the CTS.

Prior to this enhancement, the PTS, BTS, and Arbiter roles had to be reassigned manually using the System (Sysplex) Time task on the HMC.

For additional details on the API, please refer to System z Application Programming Interfaces, SB10-7030-11.

Internal Battery Feature Recommendation

Single data center

•CTN with 2 servers, install IBF on at least the PTS/CTS

–Also recommend IBF on BTS to provide recovery pro- tection when BTS is the CTS

–CTN with 3 or more servers IBF not required for STP recovery, if Arbiter confi gured

Two data centers

•CTN with 2 servers (one in each data center) install IBF on at least the PTS/CTS

–Also recommend IBF on BTS to provide recovery pro- tection when BTS is the CTS

•CTN with 3 or more servers, install IBF on at least the

PTS/CTS

–Also recommend IBF on BTS to provide recovery pro- tection when BTS is the CTS

Message Time Ordering (Sysplex Timer Connectivity to Coupling

Facilities)

As processor and Coupling Facility link technologies have improved, the requirement for time synchronization toler- ance between systems in a Parallel Sysplex environment has become ever more rigorous. In order to enable any exchange of timestamped information between systems in a sysplex involving the Coupling Facility to observe the correct time ordering, time stamps are now included in the message-transfer protocol between the systems and the Coupling Facility. Therefore, when a Coupling Facility is confi gured on any System z10 or System z9, the Cou- pling Facility will require connectivity to the same 9037 Sysplex Timer or Server Time Protocol (STP) confi gured Coordinated Timing Network (CTN) that the systems in its Parallel Sysplex cluster are using for time synchroniza- tion. If the ICF is on the same server as a member of its Parallel Sysplex environment, no additional connectivity is required, since the server already has connectivity to the Sysplex Timer.

However, when an ICF is confi gured on any z10 which does not host any systems in the same Parallel Sysplex cluster, it is necessary to attach the server to the 9037 Sysplex Timer or implement STP.
