Information about potential future products may not be incorporated into any contract. The development, release, and timing of any future features or functionality described for our products remains at our sole discretion. Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the amount of multiprogramming in the users job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here.2 © 2013 IBM Corporation

  • 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: http://www.redbooks.ibm.com/abstracts/tips0047.html http://en.wikipedia.org/wiki/Load_balancing_(computing)5 © 2013 IBM Corporation
  • 6. Plan for the Best, Prepare for the Worst ! Business Issue Solution Data Recovery Data Loss Data Redundancy ● Replicas ● Backups Load Balancing Performance Resources Redundancy ● Clusters ● Server Farms High Availability Service Downtime Systems Redundancy ● Clusters ● Server Farms Disaster Downtime of Business Systems and Site redundancy Recovery Operations ● Data centers on different locations6 © 2013 IBM Corporation
  • 7. Multi-layer architecture  Presentation layer ● HTTP Servers, Caching Proxy  Logic layer ● Application Server  Data layer ● Database server IBM Technote – Knowledge Connection for HTTP Server and WAS Plugin http://www-01.ibm.com/support/docview.wss?uid=swg270213017 © 2013 IBM Corporation
  • 8. IBM Lotus Notes/Domino and HADR8 © 2013 IBM Corporation
  • 9. IBM Lotus Notes and Domino (just a few tips) In the Domino world it’s all about Clustering and Local/Managed Replicas ● Using Clusters and Local/Managed Replicas is the ultimate 24/7 ● Run Cluster Analysis on a regular basis ● Health Checks Control Load Balancing using Server_Availability_Threshold=xx Use a Private LAN for Cluster Replication Enable multiple Cluster_Replicators=xx DEBUG_EXCLUSIVE_REPLICATION=1 ● One DB at the time ● Not good for HUB servers9 © 2013 IBM Corporation
  • 10. Deployment Idea #1: IBM Lotus Notes and Domino Mail Servers10 © 2013 IBM Corporation
  • 11. IBM DB211 © 2013 IBM Corporation
  • 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)  http://pic.dhe.ibm.com/infocenter/db2luw/v10r1/topic/com.ibm.db2.luw.admin.ha.doc/doc/c0011724.html12 © 2013 IBM Corporation
  • 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. 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. 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. Deployment Idea #2: IBM DB2 HADR16 © 2013 IBM Corporation
  • 17. Microsoft SQL Server17 © 2013 IBM Corporation
  • 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. 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. 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. 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 subscriberhttp://msdn.microsoft.com/en-us/library/ms152531(v=sql.105).aspxhttp://msdn.microsoft.com/en-us/library/ms152567(v=sql.105).aspx21 © 2013 IBM Corporation

  • 23. Understanding WebSphere Application server23 © 2013 IBM Corporation
  • 24. WebSphere Application Server 101  Deployment Manager: a server that manages operations for a logical group or cell of other servers  Cell: A group of managed processes that are federated to the same deployment manager and can include high-availability core groups  Node Agent: an administrative agent that manages all application servers on a node and represents the node in the management cell  Node: a logical grouping of managed servers  Profile: an instance of a WebSphere Application Server configuration Remember…Multiple Nodes in a Cell dont necessarily represent High Availability (Eg: Sametime 8.5)24 © 2013 IBM Corporation
  • 25. WebSphere Application Server – A graphical experience25 © 2013 IBM Corporation
  • 26. WebSphere ClusteringVertical Clustering: Multiple clustered application servers runninginside the same node.  Local Redundancy  Maximize system resources utilization (powerful machines)  Not supported by IBM Connections 4Horizontal Clustering: Multiple clustered applications running adifferent nodes.  Workload Balancing  High Availability26 © 2013 IBM Corporation

IBM Connections and HADR  You can install Connections as: ● Small Deployment ● Medium Deployment ● Large Deployment  It supports: ● DB2 ● MS SQL ● Oracle (For this one talk to your DBA)Now that your understand DB HADR and WebSphere Clusteringsolutions it should be pretty easy to architect and deploy….29 © 2013 IBM Corporation
  • 30. Creating an IBM Connections Cluster  It is already created during installation with 1 node Then...  Install WAS Network Deployment – Application Server Only  Copy JDBC files to Secondary node (same path as Primary Node)  Shared content folders are available from secondary node  Add Secondary Node to the Deployment Manager ● AddNode.sh/bat  Via ISC (aka WAS Web Console) - Create new cluster member and select secondary node  Via ISC - Add Ports and FQHN/IP to new server  Via ISC - Sync Nodes  Enable IBM HTTP Server to connect to secondary node30 © 2013 IBM Corporation
