parallel sysplex การใช้

• A Parallel Sysplex relies on one or more Coupling Facilities ( CFs ).
• By then, she said, most Skyline customers will have adopted parallel sysplex.
• Users needing larger systems can deploy IBM's S / 390 Parallel Sysplex clustering technology.
• IBM based the design of DB2 pureScale on the Parallel Sysplex implementation of DB2 data sharing on the mainframe.
• Relevant LPAR-related features on those mainframe platforms include Intelligent Resource Director, Geographically Dispersed Parallel Sysplex, and HiperSockets.
• Multiple LPARs running z / OS can form a Sysplex or Parallel Sysplex, whether on one machine or spread across multiple machines.
• In addition WLM offers interfaces which allow load balancing components to place work requests on the best suited system in a parallel sysplex cluster.
• In a Parallel Sysplex cluster the z / OS Workload Manager components work together to provide a single image view for the executing applications on the cluster.
• IBM's strategy for meeting the increased demand for mainframe power is something called parallel sysplex, which links its CMOS machines into large clusters that work in tandem.
• In late 2009, IBM announced DB2 pureScale, a shared-disk clustering scheme for DB2 9.8 on AIX that mimics the parallel sysplex implementation behind DB2 data sharing on the mainframe.
• Global Mirror can be combined with a wide area network clustering product like Geographically Dispersed Parallel Sysplex ( GDPS ), HACMP / XD, or IBM TotalStorage Continuous Availability for Windows to provide for automated failover between sites.
• The first commercial loosely coupled clustering product was " Tandem Himalayan " ( a circa 1994 high-availability product ) and the " IBM S / 390 Parallel Sysplex " ( also circa 1994, primarily for business use ).
• Two other noteworthy early commercial clusters were the " Tandem Himalaya " ( a circa 1994 high-availability product ) and the " IBM S / 390 Parallel Sysplex " ( also circa 1994, primarily for business use ).
• Mohan has worked closely with many IBM product groups worldwide and his research results have been implemented in numerous IBM and non-IBM prototypes, and products like IBM DB2, MQSeries, IBM WebSphere, Cloudscape, IBM Notes, Microsoft SQL Server and IBM System z Parallel Sysplex.
• As a result of the introduction by IBM of their Geographically Dispersed Parallel Sysplex ( GDPS ) system, which allowed for an organization to manage end-to-end application and data availability across multiple geographically separate sites, an additional seventh tier was added to represent the industry's highest possible level of service availability.
• The service classes and goal definitions are organized in service policies together with other constructs for reporting and further controlling and saved as a service definition for access to WLM . The active service definition is saved on a couple data set which allows all z / OS systems of a Parallel Sysplex cluster to access and execute towards the same performance goals.
