![]() ![]() thing we did was to add it as a minidisk for the guest user (in USER DIRECT file). Parameter can be practical depending on the Windows virtual memory size. As with any z/OS system running in an LPAR, there are occasions when. On 64-bit Windows operating systems, heap size is limited by your Windows virtual memory specification, minus a small amount of memory used by the OS and other processes. Additionally, users can enjoy the flexibility of working with mainframe and IBM i applications from virtually anywhere as they are no longer tied to a computer. However, even with a setting of 1536m, large JES output can easily exceed that value. Value to 1200m as a starting point and increasing or decreasing the value in small increments, such as 512m, until an optimum value is found. The optimal setting for a particular installation-with no OutOfMemory errors or noticeable garbage collection pauses-can only be determined by experimenting with different values. ![]() The optimum value for this parameter varies depending on the OS used, memory fragmentation, and other factors. Parameter (Eclipse default 1024m or Topaz default 2048m) used to specify the maximum heap size. The initialization files in Topaz Workbench or Eclipse (topaz.ini or eclipse.ini) include an These errors can often be avoided by increasing the maximum size of the JVM memory heap. Java OutOfMemory errors may occur when editing a large file or displaying a large JES report. ![]()
