Issue/Introduction

How to increase install scripts' JVM size to speed up the installation/upgrade on Large Datasets?

The install scripts for an upgrade may take many hours on a large datasets.

To avoid it from being slow, configure a memory.properties file that could use more memory for this script and speed up the execution. 

Environment

Release : All Supported Clarity releases

Resolution

• Create a text file memory.properties and add the two memory settings as follows in there in plain text
• Examples that you might want to add to your memory.properties file:

defaultScriptMaxMem=2560m
defaultScriptPermGenMem=512m

or

defaultScriptMaxMem=5120m
defaultScriptPermGenMem=512m

• You can use any different values, just ensure that you have enough RAM on this server to account for it. See attached example
• Place the created text file in $clarity/config prior to the upgrade.  Once the upgrade is started, it will use the JVM from this file. This will speed up bootstrap and other slower areas of the upgrade
• Note: The default values are 1024m and 128m, we want to set up higher values.
