CHECK(IBMTIMER, ZOSMIGREC_SUP_TIMER_INUSE) found that the timing synchronization mode in use on this system was ETR (which uses the Sysplex Timer). Server Time Protocol is recommended because the Sysplex Timer (9037-002) has been withdrawn from marketing and STP is planned to be its replacement. The migration action to migrate from a Sysplex Timer to Server Time Protocol is applicable to this system.
The servers and coupling facilities that are capable of supporting STP are the z10™, z9®, z990, and z890. The STP feature number is 1021. STP is a server-wide facility that is implemented in the Licensed Internal Code (LIC) of z10, z9, z990s, z890s, and coupling facilities, and presents a single view of time to PR/SM™.
Processing continues.
Notify the system programmer.
