5 Weblogic Multitenancy Key concepts 5 Tenants Virtual 1 Oracle Traffic Director Virtual 2 partition Resource Groups Resource Group Template Virtual Target 1 1 Resource Group JNDI JMS Data Source Virtual Target 2 2 Resource Group JNDI JMS Data Source Managed /Cluster Virtual Targets PDB 1 PDB 2 Container Database Deployment Scope

6 Weblogic Multitenancy Components 6 Oracle Traffic Director Oracle Weblogic Oracle Coherence Oracle Database 1 1 Resource Group JNDI Pluggable database 1 Virtual Target 1 JMS Data Source 2 2 Resource Group JNDI Pluggable database 2 Virtual Target 2 JMS Data Source

7 Weblogic Multitenancy Components Specified 7 Oracle Traffic Director Optional Provides Load balancing Installed in separate or with WebLogic in single domain Creating a WebLogic MT automatically creates a OTD 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 Portion of a WebLogic domain Dedicated to running application instances and resources Can be separately managed

8 Weblogic Multitenancy Components Specified 8 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 or level Resource Group Templates Provides a collection of deployable resources Don t have targets Can be referenced by multiple Resource Groups

10 10 Weblogic Multitenancy Consolidation

11 Weblogic Multitenancy Consolidation 11 Move from dedicated domains to Multitenant domains Less management of Hardware/VM s OS JVM s Optimal use of resources No increase in response times (According to Oracle)

12 12 Weblogic Multitenancy Consolidation

13 13 Weblogic Multitenancy Isolation

14 Weblogic Multitenancy Isolation 14 Memory and CPU isolation at the JVM level Resource Consumption Management (RCM) Virtual 1 Oracle Traffic Director Virtual 2 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 Virtual Target 1 1 Resource Group JNDI JMS Data Source Virtual Target 2 2 Resource Group JNDI JMS Data Source Data can be segregated with PDB s PDB s are not required! Managed /Cluster PDB 1 PDB 2 Container Database Per-partition management

15 Weblogic Multitenancy Isolation 15 JVM (JDK 8u40+) 1 2 Resource Group JNDI Resource Group JNDI JMS Data Source JMS Data Source 3 4 Resource Group JNDI Resource Group JNDI JMS Data Source JMS Data Source

16 16 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 17 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 WLS ) Restart a partition Fair Share Allocate a percentage of the available resource for the partition All resources available when there is no contention

20 Weblogic Multitenancy Portability for DevOps 20 Transition apps from Dev to Production environments No application changes needed Production Fast startup/shutdown Container like packaging Load balancer integration Dev

21 Weblogic Multitenancy Portability for DevOps 21 Export and Import s Via FMW Control, Console, WLST or REST Sample WLST command export(partitionname, exparchpath, [includesnlibs], [keyfile]) Provide replacement attributes <partitionname>-attributes.json in the same directory as Archive file Replace partition properties, JDBC, JMS, and other resources in resource groups import(archivefilename, [partitionname], [createnew], [keyfile])

22 Weblogic Multitenancy Portability for DevOps 22 Transition apps from Dev to Production environments Export Import Change attributes as needed Dev Test Export Import Acceptance Export Import Without any application change or redeployment Production

23 Weblogic Multitenancy Portability for DevOps 23 Cloud On premise Export -> Import to the Cloud

37 Java Cloud Service ToCloud 38 Dev Cloud ToCloud

38 Java Cloud Service ToCloud 39 Migrate your on-premise WebLogic to Java Supports version , , or > 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

39 Java Cloud Service ToCloud - How does it work? 40 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

40 Java Cloud Service ToCloud - How does it work? 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 jaap@amis.nl -cloudstoragecontainer Storage-amis/JCSContainer

44 Java Cloud Service ToCloud 45

45 Java Cloud Service ToCloud 46 Where is my domain/application? It s not yet in the JCS Wait!!! Have to perform ToCloud Import after JCS Creation Just a simple jsp that shows you what managed server you landed on.

46 Java Cloud Service ToCloud 47 One Click Migration?? Limitations Exporting JRF domains is not currently supported. s not yet supported Unsupported features will not be exported a2c-export will generate a warning if it detects JMS,WLDF,Coherence,Security However, To(SOA/PS)Cloud is coming soon! So many features will be supported pretty soon.
