Recommended service upgrade (RSU) SMP/E for z/OS User's Guide SA23-2277-01 |
|
Recommended Service Upgrade (RSU) is a preventive service philosophy that applies to z/OS®. RSU is intended to reduce the volume of PTFs customers must apply for preventive maintenance and to reduce the chance of encountering a PTF in error (PE), resulting in a more stable system. IBM® recommends that customers APPLY all RSU PTFs as preventive maintenance on their z/OS systems. However, customers must make the final decision as to what maintenance they will install. The recommended service for the following products is tested in
the Consolidated Service Test (CST) cycle:
Recommended Service Upgrades, with an SMP/E SOURCEID of RSUyymm,
are available:
For information about the latest recommended level of service, see the CST and RSU website at http://www.ibm.com/servers/eserver/zseries/zos/servicetst/. Note: Although all CST-tested PTFs become RSU PTFs, not
all RSU PTFs are tested in CST. Only the following systems or applications
are included in the CST testing: z/OS, OS/390, CICS, DB2, IMS, and MQSeries.
RSU is provided for z/OS through ESO, CBPDO, and ServerPac. |
