Create dmgr profile

cd $WAS_HOME/bin/ ./manageprofiles.sh -create \ -templatePath $WAS_HOME/profileTemplates/management \ -serverType DEPLOYMENT_MANAGER \ -profileName odmDmgr \ -profilePath $WAS_HOME/profiles/dmgr \ -enableAdminSecurity true \ -adminUserName odmAdmin \ -adminPassword password \ -cellName odmCell \ -startingPort 49000

Start dmgr server...
cd $WAS_HOME/profiles/dmgr/bin
./startManager.sh

...then log on to console...
dmgrhost.myorg.org:12501/ibm/console/

Augment dmgr profile with rules

cd $WAS_HOME/profiles/dmgr/bin ./stopManager.sh -username odmAdmin -password password cd $$WAS_HOME/bin/ ./manageprofiles.sh -augment \ -profileName odmDmgr \ -templatePath $WAS_HOME/profileTemplates/rules/management/ds cd $WAS_HOME/profiles/dmgr/bin ./startManager.sh -username odmAdmin -password password

Create profiles on node01 and node02

cd $WAS_HOME/bin/ ./manageprofiles.sh -create \ -templatePath $WAS_HOME/profiles/profileTemplates/managed \ -profileName node01 \ -profilePath $WAS_HOME/profiles/node01 \ -nodeName node01 \ -cellName node01Cell \ -federateLater true \ -dmgrHost mydmgr.myorg.org \ -dmgrPort 49003 ./manageprofiles.sh -create \ -templatePath WAS_HOME/profiles/profileTemplates/managed \ -profileName node02 \ -profilePath WAS_HOME/profiles/node02 \ -nodeName node02 \ -cellName node02Cell \ -federateLater true \ -dmgrHost mydmgr.myorg.org \ -dmgrPort 49003

cd WAS_HOME/profiles/node01/bin/ ./addNode mydmgr.myorg.org 49003 \ -conntype SOAP \ -username odmAdmin \ -password password

Augment dmgr profile with events

cd WAS_HOME/profiles/dmgr/bin ./stopManager.sh -username odmAdmin -password password ./manageprofiles.sh -augment \ -templatePath $WAS_HOME/profileTemplates/wbe/management \ -profileName odmDmgr \ -wbeHome /opt/IBM/WebSphere/AppServer/ODM/ \ -adminUserName odmAdmin -adminPassword password \ -wbeDbType Oracle \ -wbeDbName bpodev \ -wbeDbUserId WBEL1 \ -wbeDbPassword password \ -wbeDbJDBCClasspath $WAS_HOME/ODMjdbcdrivers/Oracle/ojdbc6.jar \ -wbeDbHostName 10.230.13.21 \ -wbeDbServerPort 1521 \ -wbeMsgingType Default_Messaging \ -disableBusSecurity

Augment node profiles with events

On each node...
cd WAS_HOME/profiles/node01/bin/ ./manageprofiles.sh -augment \ -templatePath ODM_INSTALL/shared/profiles/profileTemplates/wbe/managed \ -profileName node01

Configure decision server cluster

Log on to Dmgr as user who owns ODM file system.

Set ODM_HOME path environment variable...

export ODM_HOME=/opt/IBM/WebSphere/AppServer/ODM

Set decision server cluster properties...
ODM_HOME/profiles/dmgr/bin/rules/configureDSCluster.properties

If you have a non-default directory structure the configuration scripts can fail to copy rulesTemplateResource.jar files, and other runtime ears and resource adapters, from ODM directory to WAS.
To prevent this scenario, you can apply Interim Fix (iFix) 21 or the 8.5.1.1 Fix Pack.
Another work around is to manually copy...
ODM_HOME/shared/profiles/profileTemplates/rules/lib/rulesTemplateResource.jar

...to both...
WAS_HOME/profileTemplates/rules/lib
WAS_HOME/lib/

If dmgr and node servers use different directories, to ensure installation of required runtime ears and resource adapters, recreate dmgr directory structure on each node, and copy resources to node server. For example, on each node...
mkdir ALT_ODM_HOME/executionserver/applicationservers/WebSphere85
mkdir ALT_ODM_HOME/shared/profiles/profileTemplates/rules/lib
cp -r ODM_HOME/executionserver/applicationservers/WebSphere85 ALT_ODM_HOME/executionserver/applicationservers/WebSphere85
cp -r ODM_HOME/shared/profiles/profileTemplates/rules/lib ALT_ODM_HOME/shared/profiles/profileTemplates/rules/lib

Optional. Set custom member name.
Edit...
ODM_HOME/bin/rules/configureDSRulesNetworkDeployer.py

and change...
deployClusterTools.createCluster(cellName, clusterName, clusterNodeName, clusterNodeName = "-DSServer")

...to...
deployClusterTools.createCluster(cellName, clusterName, clusterNodeName, clusterNodeName = "odmDSClone01")

Set MaxPermGen heap size in...
ODM_HOME/bin/rules/configureDSRulesND.ant

On deployment manager server, create decision server cluster
cd $WAS_HOME/profiles/dmgr/bin/ ./configureDSCluster.sh -dmgrAdminUsername odmAdmin \ -dmgrAdminPassword password \ -clusterPropertiesFile $WAS_HOME/profiles/dmgr/bin/rules/configureDSCluster.properties \ -targetNodeName node01 \ -dmgrHostName mydmgr.myorg.org \ -dmgrPort 49003

On successful execution of command, decision server cluster named odmDSCluster is created.

To verify, log in to admin console and go to...
Servers | Clusters | Websphere application server

To verify, if DS server profile is created on node01, Click on...
cluster name | Cluster members

Add second node and member to decision server cluster

Optional: Change default server name in script...
DMGR_PROFILE/bin/addNodeToDSCluster.py

For example, from...
<node_name>-DSServer

...to...
deployClusterTools.createMemberOnNewNode(clusterName, clusterNodeName, "odmDSClone4");

Set MaxPermGen heap size in...
DMGR_PROFILE/bin/rules/addNodeToDSCluster.ant

Run script addNodeToDSCluster.sh...
cd $WAS_HOME/profiles/dmgr/bin/bin/ ./addNodeToDSCluster.sh -dmgrAdminUsername odmAdmin \ -dmgrAdminPassword password \ -clusterPropertiesFile $WAS_HOME/profiles/dmgr/bin/rules/configureDSCluster.properties \ -targetNodeName node02 \ -dmgrHostName mydmgr.myorg.org \ -dmgrPort 49003

Tuning of Decision Server and Events

Consider the following settings to give better decision server event runtime. Note, these are minimum and initial recommendations only and may vary based on application design and runtime load. Refer IBM redbook titled "ODM 8.5 Performance Tuning"

Number of event rule processing threads

Most event rule processing in the event run time occurs on rule processor threads. The number of these threads is controlled by the following event property:

as.director.server.ruleProcessorInstances

The following sequence shows where this is configured in the WebSphere Application Server administrative console:

Resources -> Resource environment -> Resource environment entries -> WbeSrv01 -> Custom properties

The default value is 31. If messages build up on the event destination as the rate of event production increases, then increasing the number of rule processing instances might improve the rate of event processing (by adding greater concurrency).

Tuning history processing

If history is enabled and messages are building up on the history topic or queue, you should consider increasing the maximum concurrency on the history activation specification. This will increase the concurrency of Message Driven beans (MDBs) that are writing the history data to the database. A value of 30 is suitable to start with as per IBM recommendation. This setting can be altered in the WAS administrative console using the following menu selections:

Resources -> JMS Activation specifications -> wbe_history

Event datasource connection pool

Each rule processor thread could use a database connection from the Event runtime datasource connection pool. The maximum connections setting for this connection pool should be set using the following formula as the minimum:

history MDB concurrency + value of as.director.server.ruleProcessorInstances + 10

Based on initial recommended values, it is 30 + 31 + 10 = 71. This is set in the WAS administrative console using the following menu selections:

Resources -> JDBC -> Data sources -> Event Runtime Datasource -> Connection pools

Event queue/topic connection factory connection pool

Each rule processor thread could use a JMS connection from the WbeTopicConnectionFactory connection pool. The maximum connections setting for this connection pool should be greater than or equal to the following value: value of

as.director.server.ruleProcessorInstances + 10

Considering the initial recommended values, it should be minimum 31+10 = 41. Default value for this property is 50. This is set in the WebSphere Application Server administrative console using the following menu selections:

Resources -> JMS -> Queue/Topic connection factories -> WbeTopicConnectionFactory/ WbeQueueConnectionFactory -> Connection pools

Recording History and impact on performance

History is required if you need to run reports or monitor events, actions, filters, or data in real time. When history is enabled, a significant amount of information about events, actions, and filters is written to the Decision Server Events repository. The history data can be viewed using the reports section of the Decision Server Events administration interface and the Business Space dashboards. You can produce reports that show what events enter Decision Server Events, the actions that are triggered by those events, and the event rules and filters that are evaluated in response to those events. In order to generate these reports, you need to enable history. History is disabled by default unless Business Events Tester is installed. For performance reasons, the installation of Business Event Tester it is not a preferred practice on a production system. History is tracked in history database tables that record events, actions, filters, and other assets that are processed by the Decision Server Events run time. For instructions on enabling and disabling history, see the following web page in the Operational Decision Management V8.0 Information Center:
http://pic.dhe.ibm.com/infocenter/dmanager/v8r0/index.jsp?topic=%2Fcom.ibm.wodm.dserver.events.config%2Ftopics%2Ftsk_configuring_history_runtime.html
