Carbon 4.3 - Carbon Clustering improvements o Distributed caching and clustering with Enterprise-grade software, Hazelcast.

o Introduced with Carbon 4.2

o Upgraded to Hazelcast version - 3.2.6

o Stabilization

“... the WSO2 Carbon core adds new distributed caching and clustering implementations that are based on Hazelcast... Hazelcast combines distributed data structures, distributed caching capabilities, elasticity, memcache support, and integration with Spring and Hibernate. These capabilities bring several benefits to enterprise deployments, including the ability to handle thousands of operations per second, prevent the loss of data after crashes, and dynamically scale as new servers are added.“ - Hazelcast

Carbon 4.3 - Deployment Synchronizero Vastly improved SVN-based Deployment Synchronizer support

o Now supports Subversion 1.7 and 1.8 as the working copy format

o Stabilization, and improved recovery from intermittent failures

Artifact/Deployment Synchronization

Carbon 4.3 - Pluggable Log Providers for LogViewer UIo The log view ui -

Carbon 4.3 - Pluggable Log Providers for LogViewer UIo View logs from several log storages

o File system / In memory log appender

o Cassandra as a log storage

o An SQL Server as a log storage

o A Centralized Log Viewer across the cluster

o Download archived logs

Add a new Log Providero To view logs from a custom log storage, say, Cassandra.

o Implement the interface org.wso2.carbon.logging.service.provider.api.

LogProvider

o Register it as a log provider via $CARBON_HOME/repository/conf/etc/logging-

config.xml

<loggingConfig xmlns="http://wso2.org/projects/carbon/carbon.xml"> <!-- Default log provider --> <logProviderConfig class="org.wso2.carbon.logging.service.provider.InMemoryLogProvider"> <properties/> </logProviderConfig>

<!-- Default log file provider --> <logFileProviderConfig class="org.wso2.carbon.logging.service.provider.FileLogProvider"> <properties/> </logFileProviderConfig></loggingConfig>

Add a new Log File Providero To download archived logs from a custom log storage, say, Cassandra.

o Implement the interface org.wso2.carbon.logging.service.provider.api.

LogFileProvider

o Register it as a log provider via $CARBON_HOME/repository/conf/etc/logging-

config.xml

<loggingConfig xmlns="http://wso2.org/projects/carbon/carbon.xml"> <!-- Default log provider --> <logProviderConfig class="org.wso2.carbon.logging.service.provider.InMemoryLogProvider"> <properties/> </logProviderConfig>

<!-- Default log file provider --> <logFileProviderConfig class="org.wso2.carbon.logging.service.provider.FileLogProvider"> <properties/> </logFileProviderConfig></loggingConfig>

Carbon 4.3 - Tenant Deletion Supporto Previously, WSO2 Carbon only supported tenant ‘Deactivation’

o We have added tenant deletion support as well in Carbon 4.3

Carbon 4.3 - Java Security Manager with Carbono Why use JSM with Carbon?

o How to get it to work?

o Sign all the jars inside following folders with jarsigner

o $CARBON_HOME/repository/components/plugins/

o $CARBON_HOME/repository/components/lib/

o $CARBON_HOME/lib/

o Add the following system properties to bin/wso2server.sh

-Djava.security.manager=org.wso2.carbon.bootstrap.CarbonSecurityManager \

-Djava.security.policy=$CARBON_HOME/repository/conf/sec.policy \

-Drestricted.packages=sun.,com.sun.xml.internal.ws.,com.sun.xml.internal.bind.,com.sun.imageio.,org.wso2.carbon. \

-Ddenied.system.properties=javax.net.ssl.trustStore,javax.net.ssl.trustStorePassword,denied.system.properties \
