Use the following command to add Sysplex Timer information to Keypoint I
when time-of-day (TOD) synchronization compatibility (TSC) hardware is used in
the TPF system.
Requirements and Restrictions
- This command is valid only for the basic subsystem (BSS).
- Sysplex Timer information should be included in Keypoint I only when TSC
hardware is connected to the Sysplex Timer.
- TSC hardware is required in a loosely coupled complex when a Sysplex Timer
is the synchronization source and both TOD RPQ central processing complexes
(CPCs) and Sysplex Timer-capable CPCs are present. The TSC hardware
permits TOD RPQ CPCs to receive synchronization pulses from a Sysplex
Timer.
Format
- timebase
- is the time base specified in hours (hh) and minutes
(mm).
- Note:
- You do not need to enter the ZDTIM command to determine the
correct time base because the time base does not need to match. This
variable is included to keep the format of the ZATIM commands
consistent.
- STRNM-name
- is a 1- to 4- character Sysplex Timer name.
- NETID-netid
- is a Sysplex Timer network ID from 0-31.
- STRID-strid
- is a Sysplex Timer ID from 0-15.
- SSA-ssa
- is a synchronization selection address from 0-7. This is the
TOD RPQ port that is connected to the TSC.
Additional Information
The IBM 9037 Sysplex Timer is part of the IBM Enterprise Systems Connection
Architecture.
Examples
Sysplex Timer information for STR1 is added to keypoint I in the following
example.
