      Java on Linux x86-64 supports 48-bit pointers and 256 TB of virtual address space, of which 128 terabytes is reserved for the Kernel , and 128 terabytes for User space.    Maximum Heap in  t heory on WAS Linux x86-64 would be -Xmx128t  with the caveat or requirement of having   -Xnocompressedrefs in place also, which essentially means Disabling Compressed References . Maximum Heap in practice on WAS Linux x86-64 would be approximately -Xmx76t for Java heap because the rest, or 52 TB, is used by Native heap .  *There is no Java heap size... [More]

   How and Where to increase the Maximum Heap for Application Deployment depends entirely upon whether you’re using the Admin Console , WSAdmin interface or EJBDeploy tool .   * Note that  when using the Default Gencon GC policy with  current WebSphere product releases such as v8.5.5.x & v9.x, we typically recommend both Initial and Maximum Heap values to be set to the same value. This setting avoids the additional configuration associated with resizing the heap to satisfy allocation requests and generally performs best in most... [More]

      Class loader synchronization bottlenecks are common problems brought to the attention of WebSphere Application Server L2 Support by our clients.  This is a common type of performance problem called a livelock where many threads are contending on a set of locks. The performance overhead is proportional to the lock contention, so the problem might not show up in a test environment with a low number of concurrent requests, or patterns of requests which aren't exercising the lock at the same time.  From the viewpoint of the application...

      The WebSphere eXtreme Scale (WXS) product documentation has a section on monitoring that details all the monitoring options.   However, the documentation in the Knowledge Center does not provide details of what specifically needs to be monitored and how to interpret the results. Thus, in support we are often asked “What should we monitor in WXS to determine the health of the environment?” Normally this question is in regards to environmental stability or determining the status of the environment after container start or stop.   From a...

      I would like to talk about the every popular and common features of TWSearch and saved searches for IBM Business Process Manager (BPM).   Searching! Searching for instances and tasks is a common operation in IBM BPM. Three common methods are with the TWSearch JS API ( example 2 ), exposed saved search , and the REST API searches ( saved search and query ). Something we see in Support is "How and why are my searches taking a long time?" Sometimes the performance issue is the query itself and how the query plan of the database... [More]
