=== OpenRefine Update === | |||
From Chris Evelyn | |||
Allocating more memory to OpenRefine | |||
1. The issue: I wanted to make a database with ~350,000 rows of data | |||
from VertNet but GoogleRefine 2.5 and OpenRefine 2.6 were bogging down | |||
during the 'Create' step | |||
2. Solution: allow OpenRefine to allocate more memory to its processes. | |||
The default setting is 1024Mb (~1Gig). | |||
3. What the problem looked like: during the 'Create' step the "Heap | |||
usage" would max out and show something like "1000/1000Mb used". In the | |||
newer OpenRefine versions this message pops up with a red highlight when | |||
it's maxed out. Once this happens the time to finish just grows and | |||
grows and nothing good happens. | |||
4. Fixing the problem: there are three steps to fixing this problem | |||
A) be sure that the Java development kit is installed. | |||
Get the kit here: | |||
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html | |||
Manage the path here so OpenRefine can find it: | |||
https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html | |||
B) Allocate more memory. Be sure to check whether you are using the .bat | |||
file or the .exe application to run Refine as this affects how you fix | |||
the problem. You end up having to edit the .ini files, instructions for | |||
both fixes here: | |||

The amount of memory needed will obviously vary depending on the job and | |||
on what your computer can handle. For the 350,000 rows of VertNet data | |||
(lots of columns!) I needed about 8 times the amount of default RAM | |||
(8*1024= 8192). I have 16GB RAM so this was fine but definitely keep in | |||
mind how much RAM you have an what else you are running at the time. I | |||
don't know why the increments are in multiples of 1024 but some | |||
computery person out there probably does. | |||
C) The changes may work if you close all Refine sessions and start over. | |||
If not then restart the computer. |
