![]() ![]() Since IBM JVM is in use, update setupDatabase.properties file to specify the max heap size.īegin the installation from the start after a database restore. Make the following change to the operating environment: The -XX: MaxHeapSize=16384m JVM argument is for Oracle Hotspot JVM. Java core file produced by IBM JVM shows that only 500 MB of max heap space is reserved despite setting the maxheapsize value to 16 GB. As a result, over time, with the leaking code constantly used, the cached results end up consuming a lot of Java heap space and when the leaked memory fills all of the available memory in the heap region and Garbage Collection is not able to clean it, the :Java heap space is thrown. Install Pega 7.4 with -XX: MaxHeapSize=16384m JVM arguments.Ī defect or configuration issue in the operating environment. at .( AbstractContainerFactory.java:285) JVMDUMP032I JVM requested Heap dump using ' /your_path/prpc7/stars7/tmp/PegaInstallTemp-19.18.22/load/heapdump.20180620.' in response to an event JVMDUMP032I JVM requested System dump using ' /your_path/prpc7/stars7/tmp/PegaInstallTemp-19.18.22/load/core.20180620.' in response to an event Memory used Threads Heap Memory Memory Pools Garbage Collection Suspension.

I hope this helps you, it definitely helped me.Robotic Process Automation Design Patterns Not sure what values the question marks will have on your system It is inĬ:\Program Files\IBM\Lotus\Sametime Connect\rcp\eclipse\plugins\.86_?\jvm.properties Sametime has a similar properties file which you can change to improve Sametime startup and performance. Never exceed physical RAM or performance will really suffer more than it already does. Not being memory constrained, I didn't test which is better. In Java 8, for example, the JVM will default the maximum heap size to of the physical memory of the underlying host. I have seen recommendations to make this no more than 1/3 or 1/2 of memory size. ![]() As reported on a number of posts from some skilled Notes folks, it noticeably speeds up performance. I set mine to 1024M for both and 512/256 for Sametime. ![]() Lots of time is being spent expanding and purging the Java Heap. For my machine with 6GB of memory, this is ridiculously low. The default settings for Heap Size for my system at 8.5.2 were start with 48M and grow it to 256M. Lotus Notes 8.5 (and Sametime and Designer 8.5) use the JVM virtual machine. At least one user reported this to Lotus as a bug.Ģ) JVM Heap Size can dramatically affect performance. How to analyse Websphere core. Switch to the mode that displays a single function or class at once and it will be faster. While researching this problem, I found out two interesting things that might affect you all:ġ) In the eclipse editor, if you are in the mode that displays all the code at once, pasting can be VERY slow. Eclipse showed the message about correcting indentation and would do nothing else for minutes at a time. Notes and Sametime performance with JVM Heap Size John McCann Septem11:41:34 AMI was having a problem with Domino Designer in 8.5.2, when I was editing a VERY large script library (LotusScript) and pasted a line of code into it.
