Of the Greenplum Procedural Languages PL/Java software.Install the software extension package by running the gppkg command. This example installs the PL/Java extension package on a Linux system:$ gppkg -i pljava-1.4.3-gp5-rhel-x86_64.gppkgEnsure that the environment variables JAVA_HOME and LD_LIBRARY_PATH are set properly in $GPHOME/greenplum_path.sh on all Greenplum Database hosts.Set the JAVA_HOME variable to the directory where your Java Runtime is installed. For example, for Oracle JRE this directory would be /usr/java/latest. For OpenJDK, the directory is /usr/lib/jvm. This example changes the environment variable to use /usr/lib/jvm.JAVA_HOME=/usr/lib/jvmSet the LD_LIBRARY_PATH to include the directory with the Java server runtime libraries. PL/Java depends on libjvm.so and the shared object should be in your LD_LIBRARY_PATH. By default, libjvm.so is available in $JAVA_HOME/jre/lib/amd64/server. This example adds the directory to the environment variable.LD_LIBRARY_PATH=$GPHOME/lib:$GPHOME/ext/python/lib:$JAVA_HOME/jre/lib/amd64/server:$LD_LIBRARY_PATHThis example gpscp command copies the file to all hosts specified in the file gphosts_file.$ gpscp -f gphosts_file $GPHOME/greenplum_path.sh =:$GPHOME/greenplum_path.shReload greenplum_path.sh.$ source $GPHOME/greenplum_path.shRestart Greenplum Database.$ gpstop -rEnabling PL/Java and Installing JAR FilesPerform the following steps as the Greenplum Database administrator gpadmin.Enable PL/Java in a database by executing the CREATE EXTENSION command to register the language. For example, this command enables PL/Java in the testdb database:$ psql -d testdb -c 'CREATE EXTENSION pljava;'Note: The PL/Java install.sql script, used in previous releases to register the language, is deprecated.Copy your Java archives (JAR files) to the same directory on all Greenplum Database hosts. This example uses the Greenplum Database gpscp utility to copy the file myclasses.jar to the directory $GPHOME/lib/postgresql/java/:$ gpscp -f gphosts_file myclasses.jar =:/usr/local/greenplum-db/lib/postgresql/java/The file gphosts_file contains a list of the Greenplum Database hosts.Set the pljava_classpath server configuration parameter in the master postgresql.conf file. For this example, the parameter value is a colon (:) separated list of the JAR files. For example:$ gpconfig -c pljava_classpath -v 'examples.jar:myclasses.jar'The file examples.jar is installed when you install the PL/Java extension package with the gppkg utility.Note: If you install JAR files in a directory other than $GPHOME/lib/postgresql/java/, you must specify the absolute path to the JAR file. Each JAR file must be in the same location on all Greenplum Database hosts. For more information about specifying the location of JAR files, see the information about the pljava_classpath server configuration parameter in the Greenplum Database Reference Guide.Reload the postgresql.conf file.$ gpstop -u(optional) Greenplum provides an examples.sql file containing sample PL/Java functions that you can use for testing.

For example, this command deactivates the PL/Java language in the testdb database:$ psql -d testdb -c 'DROP EXTENSION pljava;'The default command fails if any existing objects (such as functions) depend on the language. Specify the CASCADE option to also drop all dependent objects, including functions that you created with PL/Java.Note: The PL/Java uninstall.sql script, used in previous releases to remove the language registration, is deprecated.Uninstall .jar property to restrict JAR manifest algorithms- "denyAfter" checks algorithm constraints on manifest digest algorithms inside a signed JAR file. The date given in the constraint is compared against the TSA timestamp on the signed JAR file. If there is no timestamp or the timestamp is on or after the specified date, the signed JAR file is treated as unsigned. If the timestamp is before the specified date, the .jar will operate as a signed JAR file. The syntax for restricting SHA1 in JAR files signed after January 1st 2018 is: "SHA1 denyAfter 2018-01-01". The syntax is the same as that for the certpath property, however certificate checking will not be performed by this propertyCHANGES:core-svc/java.lang.management. JMX Diagnostic improvements:- com.sun.management.HotSpotDiagnostic::dumpHeap API is modified to throw IllegalArgumentException if the supplied file name does not end with “.hprof” suffix. Existing applications which do not provide a file name ending with the “.hprof” extension will fail with IllegalArgumentException. In that case, applications can either choose to handle the exception or restore old behavior by setting system property 'jdk.management.heapdump.allowAnyFileSuffix' to true.security-libs/javax.net.ssl. Custom HostnameVerifier enables SNI extension:- Earlier releases of JDK 8 Updates didn't always send the Server Name Indication (SNI) extension in the TLS ClientHello phase if a custom hostname verifier was used. This verifier is set via the setHostnameVerifier(HostnameVerifier v) method in HttpsURLConnection. The fix ensures the Server Name is now sent in the ClientHello body.xml/jax-ws. Tighter secure checks on processing WSDL files by wsimport tool:The wsimport tool has been changed to disallow DTDs in Web Service descriptions, specifically:- DOCTYPE declaration is disallowed in documents- External general entities are not included by default- External parameter entities are not included by default- External DTDs are completely ignoredTo restore the previous behavior:- Set the System property com.sun.xml.internal.ws.disableXmlSecurity to true- Use the wsimport tool command line option –disableXmlSecurity- NOTE: JDK 7 and JDK 6 support for this option in wsimport will be provided via a Patch release post July CPUBUG FIXES:- JFileChooser with Windows look and feel crashes on win 10- Race Condition in java.lang.reflect.WeakCache- java.nio.Bits.unaligned() doesn't return true on ppc- After updating to Java8u131, the bind to rmiregistry is rejected by registryFilter even though registryFilter is set- sun.management.LazyCompositeData.isTypeMatched() fail for composite types with items of ArrayType- SafePointNode::_replaced_nodes breaks with irreducible loops- NPE when JavaFX loads default stylesheet or font families if CCL is null- WebEngine.getDocument().getDocumentURI() no longer returns null for loading a String of HTML- Failed to load RSA private key from pkcs12- Improved algorithm constraints checking- Custom HostnameVerifier disables SNI extension

JADMakerJADMaker creates a JAD file for your .JAR Java Games, so that you can install them to your mobile phone.JADMaker creates a JAD file for your .JAR Java Games, so that you can install them to your mobile phone.How to use this program?There are 3 ways.1) Run JADMaker. Drag and drop a JAR file onto the window. JAD generated. That's it!2) Drag and drop a JAR file onto the JADMaker.exe icon in a Windows Explorer window.This means you can also create a desktop shortcut to JADMaker.exe, and then drop JAR file(s) onto the shortcut.3) Once the "Make JAD" Explorer Context-Menu extension is enabled (by checking it in the program),you can right click on any JAR file(s) for a quick "Make JAD".Remember that you can process multiple JAR files at one time (=batch procesing).Just select multiple files, and use any of the ways above (this is really the icing on the cake!).With so many ways to get your JAD file, you are spoilt for choice!!!

Error importing .jar with extension-templates - Extension

Complete the process.At this point you will have deployed your jar file in the SFS2X Extension folder and also saved the export configuration for future re-deployments.SFS2X can actively monitor all the Extension folders for changes and as soon as it detects an updated jar file it will restart your Extension. This is valid for all Zone-level Extensions, while it cannot be done for Room-level Extensions.In order to toggle this feature you need to launch the Server Configurator in the AdminTool and turn on the Extension file monitor option.» Assigning an Extension to a Zone or RoomThe most simple way to plug our Extension to a Zone or Room is via the AdminTool. Launch the Zone Configurator, select a Zone and enter the edit mode. You will find the Zone Extension tab where you can configure a few parameters. Essentially all you need is to select the Extension name and the main Extension class (the one extending SFSExtension).Now you can save, restart the server and the Extension will be activated. The same can be done for Room Extensions: simply access the Room Extension tab in the Room configuration panel of the Zone Configurator panel.» Python ExtensionsWe should also quickly mention that it is possible to write Python scripts and run them as Extensions, although this is not recommended for production. The reason is that interpreted Python code is not able to deliver the performance obtained with Java code and we suggest its usage only for prototyping, testing, or non performance critical projects. The process for building a Python extension is almost identical to what we have already described, but with a few small differences. You don't need Eclipse or a similar IDE to write the code. You can deploy directly your Python scripts (.py) under the Extension folder, nothing else is. Extension with single JAR file. For an extension with a single JAR file (as in the example above), the name in the Extension-List, and the prefix of the related manifest attributes, should be the name of the extension JAR file.

Address of Hazelcast Management CenterAfter starting Prometheus with this configuration, all metrics will be exported to Prometheus with the hz_ prefix. The metricsare also available via the member JMX API.With the default configuration, Management Center exports all metrics reported by the cluster members. Since it can be overlyverbose for some use cases, the metrics can be filtered with the hazelcast.mc.prometheusExporter.filter.metrics.includedor the hazelcast.mc.prometheusExporter.filter.metrics.excluded system properties, both being comma-separated lists ofmetric names.Example of starting Management Center with specifying the metrics exported to Prometheus:java -jar -Dhazelcast.mc.prometheusExporter.enabled=true \ -Dhazelcast.mc.prometheusExporter.filter.metrics.included=hz_topic_totalReceivedMessages,hz_map_totalPutLatency \ -jar hazelcast-management-center-5.5.4.jarExample of starting Management Center with specifying the metrics to be excluded from the Prometheus export:java -jar -Dhazelcast.mc.prometheusExporter.enabled=true \ -Dhazelcast.mc.prometheusExporter.filter.metrics.excluded=hz_os_systemLoadAverage,hz_memory_freeHeap \ -jar hazelcast-management-center-5.5.4.jarBy default, Prometheus connects via the same IP and port as the Management Center web interface. It is possible tooverride the port number using the -Dhazelcast.mc.prometheusExporter.port system property. Let’s say you havestarted Management Center as shown below:java -jar -Dhazelcast.mc.prometheusExporter.enabled=true \ -Dhazelcast.mc.prometheusExporter.port=2222 \ -jar hazelcast-management-center-5.5.4.jarThen, the Prometheus endpoint will be available at which should be reflected by thePrometheus configuration as below:scrape_configs: - job_name: 'HZ MC' static_configs: - targets: ['localhost:2222']If you want to visualize the Prometheus metrics using Grafana, then you can start withthis dashboard.AppDynamicsYou can use the Clustered JMX interface to integrate the Hazelcast Management Centerwith AppDynamics. To perform this integration, attach the AppDynamicsJava agent to the Management Center.After installing AppDynamics agent, you can start the Management Center as shown below:java -javaagent:/path/to/javaagent.jar \ -Dhazelcast.mc.jmx.enabled=true \ -Dhazelcast.mc.jmx.port=9999 -jar hazelcast-management-center-5.5.4.jarWhen the Management Center starts, you should see the logs below:Started AppDynamics Java Agent Successfully.Hazelcast Management Center starting on port 8080 at path : /New RelicYou can use the Clustered JMX interface to integrate the Hazelcast Management Centerwith New Relic. To perform this integration, attach the New Relic Java agentand provide an extension file that describes which metrics will be sent to New Relic.The following is an example Map monitoring .yml file for New Relic:name: Clustered JMXversion: 1.0enabled: truejmx:- object_name: ManagementCenter[clustername]:type=Maps,name=mapname metrics: - attributes: PutOperationCount, GetOperationCount, RemoveOperationCount, Hits, BackupEntryCount, OwnedEntryCount, LastAccessTime, LastUpdateTime - type: simple- object_name: ManagementCenter[clustername]:type=Members,name="member address in double quotes" metrics: - attributes: OwnedPartitionCount - type: simplePut the .yml file in the extensions directory in your New Relicinstallation. If an extensions directory does not exist there, create one.After you set your extension, attach the New Relic Java agent andstart the Management Center as shown below.java -javaagent:/path/to/newrelic.jar -Dhazelcast.mc.jmx.enabled=true\ -Dhazelcast.mc.jmx.port=9999 -jar hazelcast-management-center-5.5.4.jarIf your logging level is set to FINER, you should see the log listingin the
