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 file that could use more memory for this script and speed up the execution. 


Release : All Supported Clarity releases


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