This topic highlights what is new or changed, for users who are going to customize, administer, monitor, and tune production server environments. It also addresses those who are going to deploy and operate applications.
You can select the default software development kit (SDK) for a node on the Java SDKs page of the administrative console. The page lists all software development kits that are installed on the node. A node can have one default SDK. Servers on the node use the default SDK unless a server overrides the SDK selection and specifies a different SDK.
You can submit jobs to install and uninstall Liberty profile resources, and to start and stop Liberty profile servers. A Liberty profile server is a fast to start, dynamic application server which you can easily add features to and administer by editing XML configuration files. Liberty profile servers are available in WebSphere® Application Server Version 8.5.
This parameter specifies whether the active messaging engine must retain long running locks on the SIBOWNER table in the database.
You can configure a checkpoint to back up copies of files from the master configuration repository. A full checkpoint is a complete copy of the entire configuration repository. A delta checkpoint is a subset snapshot of the configuration repository that is made when you change a product configuration. Use a checkpoint to restore the configuration repository back to a prior state.
IBM SDK and Runtime Environment Java Technology Edition, Version 7, which is provided with WebSphere Application Server, enables you to take advantage of the Intel Advance Encryption Standard (AES) Instruction Set when performing AES Cryptography. This Instruction Set allows for improved performance when using AES Ciphers in SSL. AES is a symmetric block cipher that encrypts and decrypts data through several rounds. The enablement of this function has resulted in performance improvements in WebSphere Application Server SSL processing. To enable this function, add the JVM option -Dcom.ibm.crypto.provider.doAESInHardware to the Generic JVM arguments setting for your JVM, and set this option to true. See the IBM SDK and Runtime Environment for AIX, Java Technology Edition, Version 7 Information Center for more information about AES.
You can configure WebSphere Application Server to detect, prevent, and take action, if possible, on classloader memory leaks using the memory leak detection policy. For more information about memory leaks, read the Memory Leaks in Java Platform, Enterprise Edition applications topic.
WebSphere Application Server Version 8.5 provides a top down pattern-based memory leak detection, prevention, and action by watching for suspect patterns in application code at run time. WebSphere Application Server has some means of protection against memory leaks when stopping or redeploying applications. If leak detection, prevention and action are enabled, WebSphere Application Server monitors application and module activity performs diagnostic actions to detect and fix leaks when an application or an individual module stops. This feature helps in increasing application up time with frequent application redeployments without cycling the server.
This feature enables the usage of the MongoDB Java Driver and allows DB instances to be configured in the server configuration, injected into managed components such as EJBs, and looked up in JNDI. Applications interact with these DB instances via the normal MongoDB APIs.
This command recovers the configuration data of the messaging engine of queues and topics from the message store.
Version 8.5 adds support for the Service Component Architecture (SCA) OASIS programming model implementation.
The IBM Support Assistant Data Collector for WebSphere Application Server tool focuses on automatic collection of problem data. It also provides symptom analysis support for the various categories of problems encountered by IBM software products. Information pertinent to a type of problem is collected to help identify the origin of the problem under investigation. The tool assists customers by reducing the amount of time it takes to reproduce a problem with the proper RAS tracing levels set, as well as by reducing the effort required to send the appropriate log information to IBM Support.
