Both WebSphere Application Server (WAS) V855x and V9 support Java Standard Edition 8 (Java SE 8). However, the installation images required for both are different and unique:   For WAS V855x, the Java SE8 is optionally supported. In order to use Java SE 8 for WAS you need to download the recommended Java SE 8 fixpack build that is made available with the WAS fixpack. The WAS fixpack page will provide a link for the Java SE 8 fixpack that is made available for installation with the WAS fixpack. The Java SE 8 fixpack can then be... [More]

  Javacores are generally not useful by themselves to analyze memory problems. However, javacores are still useful for providing hints on where memory may be accumulating by reviewing the NATIVEMEMINFO section.   Using 2 or more javacores from the same process ID (PID), compare the NATIVEMEMINFO sections from during the time frame when memory growth is noticed . The following example shows the NATIVEMEMINFO section from 2 javacores when it was noticed by the system administrator that the process size (not to be confused with the java... [More]

  A JDK (Java Development Toolkit) is a base component of WebSphere Application Server (WAS).   Different versions of WAS support specific versions of the JDK.  You can identify the JDK used by your version of WAS from the output of the java -version command or in a javacore. Detail: WebSphere Application Server V8.5 can use JDK 1.6.1, 1.7.0, 1.7.1 and now V8.0. ** Note: The Sun and HP-UX platforms do not have the 1.7.1 or 1.6.1 builds. 1.8.0 - IBM J9 VM Example java -version output: java version "1.8.0" Java(TM)...

  Configuring the batch environment: Configuring the batch environment includes configuring the job scheduler and grid endpoints. The job scheduler accepts job submissions and determines where to run them. Configurations for the job scheduler includes the selection of the deployment target, datasource JNDI name, database schema name, and endpoint job log location to be configured for the schedule. Batch applications are hosted in grid endpoints. 1. Configuring the job scheduler: The first time a server or cluster is selected to host the... [More]

  Debugging Java exceptions is not always easy to do as the exception messages are often too generic. IBM SDK has provided a mechanism for triggering additional data generated on various events using the -Xdump option. It allows an additional level of filtering on the method that is throwing the exception. Javacore and System dump are useful to capture detailed information about the general state of the Java runtime and the application running on it. We can generate those dumps on purpose when certain exception raises from specified... [More]
