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:
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.
