Tomcat Java web applications
Changed all instances of "INFO" to "ERROR" in the following config file to reduce disk I/O and CPU load.
nano /home/dspace/config/log4j.properties
Then copied the file to dspace-src config folder.
SOLR
Log level
Please note: The procedure below is not stable, so I installed PSI Probe using the Tomcat manager web interface and now I set the SOLR log level via the web gui after each re-build. See: https://code.google.com/p/psi-probe
See: http://lucidworks.lucidimagination.com/display/solr/Configuring+Logging and https://jira.duraspace.org/browse/DS-1460
Create the following file:
nano /home/dspace/dspace-1.8.2-src-release/dspace/modules/solr/src/main/webapp/WEB-INF/classes/logging.properties
Add the following to the file:
org.apache.commons.digester.Digester.level = WARNING org.apache.solr.level = SEVERE
- NANO Editor Help
| CTL+O | = Save the file and then press Enter |
| CTL+X | = Exit "nano" |
| CTL+K | = Delete line |
| CTL+U | = Undelete line |
| CTL+W | = Search for %%string%% |
| CTL+\ | = Search for %%string%% and replace with $$string$$ |
| CTL+C | = Show line numbers |
More info = http://en.wikipedia.org/wiki/Nano_(text_editor)
Save the file and rebuild.
Log file permissions
I setup a root cron crontab as follows.
sudo -i
crontab -e
Add the following line.
@midnight chmod 0777 -R /home/dspace/log
Save the crontab edit.
