DISCLAIMER - This is a possible solution but each customer environment is different and may require additional tuning. It is suggested to contact Workload Scheduler Support team to discuss any configuration changes.
TUNING
Use Oracle jdbc type 4 as the datasource object type in WebSphere. This has already been done as I understand.
Change maxThreads from 10 to 50 in the file resources-pme.xml. Add
cacheSize parameter to TWSConfig.properties file
Tune the datasource connection pool settings for minConnections and
maxConnections in resources.xml
Change maxThreads from 10 to 50 in the file resources-pme.xml.
Location: TWA_HOME/WAS/TWSProfile/config/cells//nodes/DefaultNode/servers//resources-pme.xml
Create a backup copy of resources-pme.xml and then change line:
From:
factories xmi:type="workmanager:WorkManagerInfo" xmi:id="WorkManagerInfo_Default" name="DefaultWorkManager" jndiName="wm/default" description="WebSphere Default WorkManager" category="Default" minThreads="1" maxThreads="10" threadPriority="5" numAlarmThreads="5" isGrowable="false" workReqQFullAction="0"
To:
factories xmi:type="workmanager:WorkManagerInfo" xmi:id="WorkManagerInfo_Default" name="DefaultWorkManager" jndiName="wm/default" description="WebSphere Default WorkManager" category="Default" minThreads="1" maxThreads="50" threadPriority="5" numAlarmThreads="5" isGrowable="false" workReqQFullAction="0"
Tune the datasource connection pool settings for minConnections and maxConnections in resources.xml.
Location:
TWA_HOME/WAS/TWSProfile/config/cells//nodes/DefaultNode/servers//resources.xml
Create a backup copy of resources.xml and then change the line:
connectionPool xmi:id="ConnectionPool_1493330406573" connectionTimeout="180" maxConnections="30" minConnections="1" reapTime="180" unusedTimeout="1800" agedTimeout="0" purgePolicy="EntirePool" numberOfSharedPoolPartitions="0" numberOfUnsharedPoolPartitions="0" numberOfFreePoolPartitions="0" freePoolDistributionTableSize="0" surgeThreshold="-1" surgeCreationInterval="0" testConnection="true" testConnectionInterval="15" stuckTimerTime="0" stuckTime="0" stuckThreshold="0"/
To:
connectionPool xmi:id="ConnectionPool_1493330406573" connectionTimeout="180" maxConnections="50" minConnections="0" reapTime="180" unusedTimeout="1800" agedTimeout="0" purgePolicy="EntirePool" numberOfSharedPoolPartitions="0" numberOfUnsharedPoolPartitions="0" numberOfFreePoolPartitions="0" freePoolDistributionTableSize="0" surgeThreshold="-1" surgeCreationInterval="0" testConnection="true" testConnectionInterval="15" stuckTimerTime="0" stuckTime="0" stuckThreshold="0"/
Add cacheSize parameter to TWSConfig.properties file.
Open the file TWSConfig.properties:
com.ibm.tws.planner.monitor.cachesize=20000
All these settings take effect after restarting the TWS WebSphere server instance.
