Weblogic MultitenancyComponents Specified

• Oracle Traffic Director

– Optional

– Provides Load balancing

– Installed in separate or with WebLogic in single domain

– Creating a WebLogic MT Partition automatically creates a OTD Partition

• Virtual Target

– A virtual target can be used by only one partition or domain

– One or more virtual targets per resource group

– A virtual target can be used by many resource groups within a partition

– Route by host name and/or URI prefix and/or port number

• Domain Partition

– Portion of a WebLogic domain

– Dedicated to running application instances and resources

– Can be separately managed

8

Weblogic MultitenancyComponents Specified

• Resource Groups

– Separate group of deployable applications, libraries, jms servers and queues, data sources

– Can be derived from a Resource Group Template (See below)

– Override resource settings as needed when derived

– Create at Domain or Partition level

• Resource Group Templates

– Provides a collection of deployable resources

– Don’t have targets

– Can be referenced by multiple Resource Groups

Consolidation

11

Weblogic MultitenancyConsolidation

• Move from dedicated domains to Multitenant domains

• Less management of

– Hardware/VM’s

– OS

– JVM

– Domains

• Optimal use of resources

• No increase in response times (According to Oracle)

Isolation

14

Weblogic MultitenancyIsolation

• Memory and CPU isolation at the JVM level

– Resource Consumption Management (RCM)

– Oracle JDK 8u40

• Virtual Target per partition for application access

• Dedicated JNDI tree for resource isolation

• Workmanager per partition for thread management

• Security realm per partition possible

• Data can be segregated with PDB’s

– PDB’s are not required!

• Per-partition management

Resource Consumption Management

• Resource Consumption Management is introduced in JDK 8u40

– Only with G1 Garbage collector

• Enable Resource Consumption Management

– $DOMAIN_HOME/bin/startWeblogic.sh

– #JAVA_OPTIONS="-XX:+UnlockCommercialFeatures -XX:+ResourceManagement -XX:+UseG1GC

${SAVE_JAVA_OPTIONS}"

– Or put this line in setUserOverrides.sh in $DOMAIN_HOME/bin/

• Supported resources

– FileOpen: The number of open file descriptors in use by a partition

– HeapRetained: The amount of heap (in MB) retained/in use by a partition

– CpuUtilization: The percentage of CPU time utilized by a partition with respect to the available CPU time of the

WebLogic process

17

Resource Consumption Management –Policy Types

• Triggers

– Notify• Notify system administrator that a threshold has been reached

– Slow• Reducing the thread-usage time for the partition

– Fail• Fails resource consumption requests – Only applicable for Open Files

– Shutdown• Inititate shutdown of a partition

– Restart (Since WLS12.2.1.1)

• Restart a partition

• Fair Share

– Allocate a percentage of the available resource for the partition

– All resources available when there is no contention

Portability for DevOps

20

Weblogic MultitenancyPortability for DevOps

• Transition apps from Dev to Production environments

• No application changes needed

• Fast startup/shutdown

• Container like packaging

• Load balancer integration

• Export and Import Partitions

• Via FMW Control, Console, WLST or REST

• Sample WLST command

– exportPartition(partitionName, expArchPath, [includeAppsNLibs], [keyFile])

– Provide replacement attributes• <partitionName>-attributes.json in the same directory as Partition Archive file

• Replace partition properties, JDBC, JMS, and other resources in resource groups

– importPartition(archiveFileName, [partitionName], [createNew], [keyFile])

Java Cloud Service

30

Java Cloud ServiceWeblogic Multitenancy

• Weblogic 12.2.1.0.0 available in the Java Cloud Service

• Migrate your on-premise WebLogic Server Domain to Java

• Supports version 10.3.6, 12.1.2, 12.1.3 or 12.2.1 -> JCS 12.x

• Move archive file directly to the Storage Cloud available for JCS

• Create your own overrides file to adjust attributes

• Available on OTN

40

Java Cloud ServiceAppToCloud - How does it work?

• Set JAVA_HOME – Java version >= 7

• Perform Healthcheck

– ./a2c-healthcheck.sh -oh /u01/app/oracle/product/wls1036 -adminUrl t3://wls11.domain.local:7001 -outputDir

/tmp/oracle_jcs_app2cloud/output -adminUser weblogic

41


• Export domain to archive file

– Shutdown domain (recommended)

• local filesystem -> upload to Storage Cloud manually

– ./a2c-export.sh -oh /u01/app/oracle/product/wls1036 -domainDir

/u01/app/oracle/config/domains/wls_domain_tst10 -archiveFile

/tmp/oracle_jcs_app2cloud/output/wls_domain_tst10.zip -clusterToExport Cluster_1

• Directly to the Storage Cloud

– Add parameters

-cloudStorageUser [email protected] -cloudStorageContainer Storage-amis/JCSContainer

• Where is my domain/application?

– It’s not yet in the JCS

• Wait!!!

• Have to perform AppToCloud

Import after JCS Creation

• https://141.144.33.210/whichServer/whichServer.jsp

– Just a simple jsp that shows you what managed server you landed on.

https://141.144.33.210/whichServer/whichServer.jsp

47


• One Click Migration??

• Limitations

– Exporting JRF domains is not currently supported.

– Domain Partitions not yet supported

– Unsupported features will not be exported

– a2c-export will generate a warning if it detects JMS,WLDF,Coherence,Security

• However, AppTo(SOA/PS)Cloud is coming soon!

– So many features will be supported pretty soon.
