Java Standards SupportJEE 7 supported APIs

• Java EE 7 will be fully supported in WebLogic 12.1.4 release• As of 12.1.3 release the following JEE APIs are supported:

Java API for WebSocket (JSR 356)Java API for JSON Processing (JSR 353)Java API for RESTful Web Services 2.0 (JSR 339)Java Persistence API 2.1 (JSR 338)


Updated WebSocket Protocol SupportJava EE 7 WebSocket API

• WebLogic 12c fully supports WebSocket Protocol (RFC 6455)• As of release 12.1.3 WebLogic supports JSR 356 which enables application

developers to use the standard Java EE 7 WebSocket API• The proprietary WebLogic Server WebSocket API that was introduced in

release 12.1.2 is deprecated but remains supported for backward compatibility


WebSocket Protocol PerformanceScalability, Performance

• Message Echo Benchmark–WebSocket Clients connect, send messages

every second– Server broadcasts back to clients

• Single WLS Server– Reliably support 60,000 connections – Throughput measured at

~20,000 messages/second with a 512 byte payload

WebLogic WebSockets

60k Connections

20k msgs/sec


Updated Maven Support

• Oracle Maven Sync Plugin• WebLogic Maven Plugin– New goals– New archetypes


Oracle Maven Sync PluginPush artifacts from an Oracle Home

• Populates a local or shared repository with WebLogic jars & archetypes• Patch & resync to maintain repository up-to-date• Sample goals– Push to local repository

– Perform a ‘dry-run’ to see what will get pushed

$ mvn com.oracle.maven:oracle-maven-sync:push -Doracle-maven-sync.oracleHome=$ORACLE_HOME

$ mvn com.oracle.maven:oracle-maven-sync:push -Doracle-maven-sync.oracleHome=$ORACLE_HOME-Doracle-maven-sync.testOnly=true


Oracle Maven Sync PluginInstall

• oracle-maven-sync plugin coordinates– GroupId: com.oracle.maven– ArtifactId: oracle-maven-sync

• Install directly using Maven install goal$ cd $ORACLE_HOME/oracle_common/plugins/maven/com/oracle/maven/oracle-maven-sync/12.1.2

$ mvn install:install-file -Dfile=oracle-maven-sync.12.1.2.jar -DpomFile=oracle-maven-sync.12.1.2.pom


Weblogic Maven PluginNew Goals

• Coordinates for weblogic-maven-plugin– GroupId: com.oracle.weblogic– ArtifactId: weblogic-maven-plugin

• Supports operational tasks from a Maven project– Install WebLogic Server– Create Domains– Start Servers– Execute WLST scripts

• Goals can run remotely (without a local WLS installation)

– Deploy applications, libraries– Start, stop applications– Pre-compile applications–WS generation, packaging


Weblogic Maven PluginArchetypes

• WebLogic Server 12c (12.1.2) provides five archetypes

• Installed into the repository when the oracle-maven-sync plugin is executed• Execute maven archetype:crawl goal to discover and use archetypes

basic-web JSF, CDI with weblogic-maven-plugin

basic-webapp-ejb JSF, CDI, JPA with weblogic-maven-plugin

basic-mdb JSF, CDI, MDB with weblogic-maven-plugin + WLST

basic-webservice Web Service with weblogic-maven-plugin JWSC goals

maven-gar-archetype Skeleton project and configuration files for a GAR


Dynamic Clusters & Server TemplatesScale Clusters by Changing one Parameter

• Create cluster based on server template• Rules for calculating server-specific attributes– Server name, listen ports, machines

• # of servers can be dynamically changed• Building block for elasticity• Whole server migration supported• Auto-scaling coming soon [12.1.4]– Elastic Clusters

Oracle Database 12c IntegrationApplication Continuity

• On a loss of database service AC rebuilds the database session and executes the history accumulated during the request

• Works with both Active GridLink for RAC and Generic Datasources

• Supports both read and write operations; No XA support yet

• Requires Oracle 12c JDBC Driver and Oracle 12c Database

• Configuration and Usage– oracle.jdbc.replay.OracleDataSourceImpl– Replay Initiation Timeout– Disabling AC for a connection if (con instanceof oracle.jdbc.replay.ReplayableConnection)

((oracle.jdbc.replay.ReplayableConnection) connection).disableReplay();


Oracle Database 12c IntegrationDatabase Resident Connection Pooling

• Prior to DRCP, one process creates/holds database sessions that are exclusively used by that process (dedicated severs)– sessions are shared between the different threads of one WLS server– it can potentially lead to a huge number of database sessions

• Using DRCP sessions are kept on the (database) server side (pooled servers)– sessions are shared between different WLS servers– suitable for applications with many short-lived database interactions

• Works with both Active GridLink for RAC and Generic Datasources• Requires Oracle 12c JDBC Driver and Oracle 12c Database


Oracle Database 12c IntegrationDatabase Resident Connection Pooling

• Configuration– Change the URL to include a suffix of :POOLED or

(SERVER=POOLED) for service URLs.– Specify the value/name pair of the DRCP

connection group/pool as a connection property

– DRCP must be enabled on the database side

oracle.jdbc.DRCPConnectionClass=myDRCPpool

Oracle Database 12c IntegrationSupport for PDBs/CDBs, GDS, Automatic ONS

• Container Database (CDB) is a feature that optimizes resources by consolidating multiple Pluggable Databases (PDB) or tenants in a single CDB– Both CDBs and PDBs are supported in WebLogic 12c– Access to PDBs is transparent to the datasource; PDBs are presented as non-CDB

databases

• Global Database Services (GDS) provides automated load balancing, fault tolerance and resource utilization in a distributed database environment• When defining an Active GridLink datasource the ONS list is automatically

provided from the database to the driver


Managed Coherence ServersCoherence Clusters & Cluster Members as First-class Citizens

• Coherence Clusters are configured as part of the WebLogic Domain • Managed Coherence Severs are WebLogic Managed Servers that configured

as Coherence Cluster members WebLogic Domain

Managed Coherence ServersWebLogic Management Framework

• Introduces the Coherence Application / Grid ARchive (GAR) – Follows the Java EE model– Consolidates libraries & configuration into a single distributable entity– GAR can also be packaged in WebLogic EAR

• Leverages WebLogic Management Framework– Configuration Wizard, Admin Console, WLST, JMX, FMWC, Deployment tools– Node Manager for lifecycle management of cluster members– Coherence libraries on the system classpath (no need to package in your application)

• Coherence remains available “standalone” including support for GARs


WebLogic

WebLogic JMSReminder :: JMS Extensions

• Unit of Order– Messages with same Unit of Order (UOO) are processed in order– Stronger ordering semantics than the JMS specification

• Unit of Work– Messages are grouped with a group identifier– Messages at final destination become available only when entire

group arrives

• Store and Forward Messaging– Store messages locally and forward to remote server when

available– Clients to server and server to server

• Distributed Destinations– Queues/Topics in a cluster appear as a single logical destination– High availability, scalability, parallel processing and load balancing

Mapping and Persistence FrameworkOracle TopLink 12c new Features

• NoSQL database support– Objects can be mapped to non-relational (NoSQL) data sources– Oracle NoSQL, MongoDB and others

• Client/Tenant isolation, where multiple application tenants may share database tables and schemas– Single-Table with discriminator columns– Table-per-Tenant– Virtual Private Database (VPD) compatible JDBC driver

• Support for Oracle Database Continuous Query Notification (CQN)– The DB notifies TopLink of changes so that objects in the shared cache can be invalidated – Live Queries (Query Result Change Notification, QRCN)


WebLogic 12cThat’s NOT all Folks!

• OSGi Bundes for WebLogic Server Applications– Deploy OSGi Bundles and use them in your JEE applications

• WebLogic JMS Resource Adapter for Foreign Application Server Integration– JCA compliant resource adapter to provide high performance integration of a

WebLogic JMS client with foreign application servers

What’s Next? Sneak Peek at WebLogic Server 12.1.4Multitenancy Use Cases

• Software as a Service– Classic SaaS – one app copy per tenant, with dedicated resources per tenant– Departmental Applications – One app copy per department/LOB– Regional or Geographic Application Instances – App copy per region with

customizations (properties files, text files, GIFs) per copy (e.g., ecommerce/customer experience applications)

• Consolidation– Increase Density–Multiple Applications for Multiple Tenants – Multiple application groups available to

tenants in various combinations; each tenant gets copy of desired apps/resources


What’s Next? Sneak Peek at WebLogic Server 12.1.4Elastic Clusters

• Administration APIs for Dynamic Clusters– Start/stop a specified number of servers – Expand/shrink the size of the cluster–Manage server lifecycle, quiescence

• Configurable rules for cluster scaling– Thresholds based on user-defined metrics– Drive scaling changes– (Potential) Drive other configuration changes
