Pega installation

Hi there,


We are having problem asking client to add more memory from 4GB to 8 GB.

Below is the current PROD server - JVM arg.

-Dcatalina.base=C:\apache-tomcat-7.0.52 -Dcatalina.home=C:\apache-tomcat-7.0.52 -Djava.endorsed.dirs=C:\apache-tomcat-7.0.52\endorsed -Djava.io.tmpdir=C:\apache-tomcat-7.0.52\temp -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=C:\apache-tomcat-7.0.52\conf\logging.properties -Xms4096m -Xmx4096m -XX:PermSize=512m -XX:MaxPermSize=1024m -XX:NewSize=1024m -XX:MaxNewSize=1024m -XX:+HeapDumpOnOutOfMemoryError -XX:+UseCompressedOops -XX:ReservedCodeCacheSize=512m -XX:+UseCodeCacheFlushing -XX:TargetSurvivorRatio=90 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=80 -XX:+CMSClassUnloadingEnabled -XX:+DisableExplicitGC -Djava.awt.headless=true -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps -verbose:gc -Xloggc:C:\apache-tomcat-7.0.52\logs\gc.log exit -Xms4096m -Xmx4096m -Xss128k


The client is on 7.1.7 and they believe 4GB is valid as stated in 717

https://pdn.pega.com/documents/pega-717-installation-guide-apache-tomcat-mssql

On Windows — setenv.bat

set JAVA_OPTS=-Xms2048m –Xmx4096m –XX:PermSize=64m –XX:MaxPermSize=384m


However, from 7.1.7 onwards the recommended memory in the restallation doc has changed -

Pega Installation for Tomcat/MSSQL "Pega718_Install_Tomcat_MSSQL.pdf"  recommends

On Windows — setenv.bat

set JAVA_OPTS=-Xms4096mXmx8192m –XX:PermSize=512m –XX:MaxPermSize=1024m

1. Is there a significant change from 717 to 718-719 and so the memory has been bumped up, or is this an error in documentation?

2. What is the recommended memory settings for standard pega installation?

Regards

Seri
