
Drew Wills and Jacob Lichner from Unicon worked with us to re-skin
uPortal 4.0.

Drew worked with us to migrate our uPortal from 3.1 to 4.0.

We decided to start from scratch on student layouts. We deleted all
database content.



We moved from SVN to GitHub for our source code repository.
Using GitHub has improved our upgrade process to include patches
from the latest Jasig releases
We implemented Groovy Build process which helps with rapid
deployment of uPortal. Puppetmaster script runs Maven and Ant
commands
We created Quickstart data to help streamline the Portal build
process

Load test. Load is higher than prior versions.
Use initportal on the first node and then deploy-ear on all other
nodes. We had layout issues with our tabs because we used
initportal on all nodes.
Have a minimum of 4 gb for heap space. We were experiencing
Tomcat crashes and Tomcat 500 errors.
Reduce logging levels to info or warn. Some portlets come with
logging levels of debug or trace and this caused a lot of RAM
usage and IO on disk.
We fine tuned our PostgreSQL database to optimize our uPortal
performance

We deactivated uPortal event tracking. This was putting a high
load on front ends and database server and utilizing 50% of our
switch traffic. 500 mb per second.
We had to change code on OU and Jasig portlets to catch and not
display 503 errors.
We doubled physical memory on front ends and database server
from 12 to 24 gb
With uPortal 4.0.5 and our additional portlets we found a
need to increase the amount of files that could be opened at
once in the OS, the default for Red Hat Enterprise Linux was
1024, we increased this to 2048.
