Abstract
Server Time Protocol (STP) is a server-wide facility that is implemented in the Licensed Internal Code (LIC) of IBM® System z10® and IBM System z9®, and IBM eServer™ zSeries® z990 and z890 servers. It provides improved time synchronization in a sysplex or non-sysplex configuration.
This IBM Redbooks® publication will help you configure a Mixed or STP-only Coordinated Timing Network. It is intended for technical support personnel requiring information about:
- Installing and configuring a Coordinated Timing Network
- Using STP functions and operations
- Migrating to a Coordinated Timing Network from various timing environments
Readers are expected to be familiar with IBM System z® technology and terminology. For planning, see our companion book, Server Time Protocol Planning Guide, SG24-7280. For information about how to recover your STP environment functionality, see Server Time Protocol Recovery Guide, SG24-7380.
