Best Practices for SAP BI using DB2 9 for z/OS - IBM Redbooks

– MCOD - System z first - reduces complexity.
– Proven automation and end-to-end systems management.
– DR ready - GDPS® - cold, warm, and hot.
– Non-disruptive CBU on/off.
– z/OS and DB2 skills and tools.
– Online backup and reorganizations (DB2 Online Reorg solutions are
unique) eliminate the major cause of planned outages.
– Storage technology (FlashCopy, Snapshot). Integration of the disk
controller database copy with the DBMS is unique with DB2 and ESS
providing seamless, low overhead database backup.
– Self-tuning DASD - Parallel Access Volumes, multiple allegiance. Disk
controller Parallel Access Volumes (PAVs) with z/OS eliminate disk hot
spot tuning typical of a UNIX or Windows database server environment.
PAV operates across LPARS for multiple allegiance.
► Leverage and protect investment. Some System z/DB2 capabilities that
provide total cost of ownership (TCO) and service level advantages are:
– Multiple LPARs and priority schemes.
– z/OS and Linux application servers.
– MCOD - System z first - reduce complexity.
– Proven automation and end-to-end systems management.
– Disaster Recovery (DR) ready using a Geographically Dispersed Parallel
Sysplex (GDPS), which is a S390 implementation that enables high
availability across sites up to 40 km apart — cold, warm, and hot.
Capacity backup (CBU), primary site 12 engines, DR site 6 engines, in
event of failover dynamically turn on additional engines.
Peer-to-peer remote copy (PPRC).
Asynchronous remote copy (XRC).
