  5. 5. Key Concepts Load Balancing ● “…is a computer networking methodology to distribute workload across multiple computers or a computer cluster….or other resources, to achieve optimal resource utilization, maximize throughput, minimize response time, and avoid overload” High Availability ● “…ability to continue processing and functioning for a certain period of time - normally a very high percentage of time, for example 99.999%. …. Similarly, clustering and coupling applications between two or more systems can provide a highly available computing environment.” Disaster Recovery ? ***** ● “…is an IT-focused plan/architecture designed to restore operability of the target systems, applications, or computer facility at an alternate site after an emergency” Sources: © 2013 IBM Corporation

  11. 11. IBM DB211 © 2013 IBM Corporation
  12. 12. IBM DB2 – High Availability Disaster Recovery  Data is synchronized via Log Shipping  Clients are rerouted using “Automatic Client Reroute”  Synchronization modes ● SYNC (synchronous) ● NEARSYNC (near synchronous) ● ASYNC (asynchronous) ● SUPERASYNC (super asynchronous)  © 2013 IBM Corporation
  13. 13. IBM DB2 Log Shipping and Mirroring  Log Mirroring ● It provides Data Redundancy ● Data is duplicated ● Please use a different disk controller  Log Shipping ● It provides High Availability ● If primary fails: – The remaining logs are transferred over to the standby machine. – The standby database rolls forward to the end of the logs and stops. – The clients reconnect to the standby database and resume operations.13 © 2013 IBM Corporation
  14. 14. IBM DB2 High Availability Feature  Enables integration between IBM® DB2 server and cluster managing software  It provides infrastructure for enabling the database manager to communicate with your cluster manager when instance configuration changes, such as stopping a database manager instance, require cluster changes  Supported clustering tools ● IBM® PowerHA® SystemMirror for AIX® ● Tivoli® System Automation for Linux ● Microsoft Cluster Server, for Windows operating systems ● Sun Cluster, or VERITAS Cluster Server, for the Solaris operating system ● Multi-Computer/ServiceGuard, for Hewlett-Packard14 © 2013 IBM Corporation
  15. 15. IBM DB2: Other HADR Options  DB2 Fault Monitor ● UNIX based OS only (Linux, AIX) ● It will restart the DB2 instance if it ends unexpectedly ● Not compatible with high availability clustering products such as IBM PowerHA® SystemMirror for AIX® or IBM Tivoli® System Automation for Multiplatforms (SA MP)  Automatic Client Reroute ● It will establish a connection with an alternate DB2 instance ● Configured via Code or WAS ISC15 © 2013 IBM Corporation
  16. 16. Deployment Idea #2: IBM DB2 HADR16 © 2013 IBM Corporation
  17. 17. Microsoft SQL Server17 © 2013 IBM Corporation
  18. 18. MS SQL Server - Failover clustering  Based on Windows Server failover clusters  Provides High Availability at the Database Server Instance level  Appears on the network as a single SQL Server instance on a single computer  SQL Server Cluster will listen on virtual IP address for the cluster (not the individual machines)  All nodes are connected to a shared storage for SQL data18 © 2013 IBM Corporation
  19. 19. MS SQL Server - Mirroring  Configured at the Database level  1:1 Failover  3 Modes of operation: ● High-safety – Transaction is committed to mirrored server, then to the principal ● High-performance mode – Primary server doesnt wait for transaction to be committed to mirrored server ● High-safety mode with automatic failover – Requires a 3rd server. The Witness server – Failover is performed only if Witness and Mirrored server remain connected to each other19 © 2013 IBM Corporation
  20. 20. MS SQL Server: Log Shipping  Configured at the Database level  1:N Failover  Supports limited read-only access to secondary databases (during the interval between restore jobs)  Related Jobs: ● Backup ● Copy ● Restore ● Alert (With Optional Monitor Server)20 © 2013 IBM Corporation
  21. 21. MS SQL Server - Replication  Configured at the Database level  1:N Failover  Replication types ● Snapshot replication ● Transactional replication ● Merge replication  Replication models ● Peer-to-peer ● Central publisher ● Central publisher with remote distributor ● Central subscriber ● Publishing subscriber © 2013 IBM Corporation
