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 user's job stream, the I/O configuration, the storage configuration, and the workload processed.

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”

IBM Lotus Notes/Domino and HADR


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 servers


Deployment Idea #1: IBM Lotus Notes and Domino Mail Servers


IBM DB2


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.html


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.


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-Packard


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 ISC


Deployment Idea #2: IBM DB2 HADR


Microsoft SQL Server


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 data


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 doesn't 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 other


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)


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

Deployment Idea #3: MS SQL Server (MS Cluster and Mirroring)

Hosted in ATL


Understanding WebSphere Application server


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 don't necessarily represent High Availability (Eg: Sametime 8.5)


WebSphere Application Server – A graphical experience


WebSphere Clustering

Vertical Clustering: Multiple clustered application servers running inside the same node. Local Redundancy Maximize system resources utilization (powerful machines) Not supported by IBM Connections 4

Horizontal Clustering: Multiple clustered applications running a different nodes. Workload Balancing High Availability


IBM Connections and HADR


Quick Test

Difference between Vertical Cluster and Horizontal Cluster ?

Which SQL HADR option is the recommended for IBM Connections?


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 Clustering solutions it should be pretty easy to architect and deploy….


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 node


Deployment Idea # 4: IBM Connections and HADR (Medium Deployment)


IBM Sametime and HADR


Deployment Idea # 5: IBM Sametime & HADR (Large Deployment)


Mobile Solutions


Deployment Idea # 6: IBM Traveler

Lot of sessions about Traveler


Deployment Idea # 7: BES 5.x and HADR – A custom solution
