[Dspace-tech] Thumbnails created in shell/not created in cron job

[Thomas A McGee]

Following up on my earlier post, I was getting errors when running the ./filter-media command with the flags to only run the JPEGFilter. I tried it again with no flags, and presto! thumbnails created. The librarians are very happy with them.

OK, so then I check my crontab to see what's going on. Running from a command line:
/usr/home/dspace/app/dspace/bin/filter-media -v

generates a nice page of results with a few warnings.

Setting a crontab entry according to the cookbook to:
5 2 * * * /usr/home/dspace/app/dspace/bin/filter-media -v >> /tmp/mediafilter.log 2>&1

returns this mess to the output log file:

Crontab was set up as user 'dspace', which is the user account used for the successful command-line execution. The log file is created and owned by user 'dspace' as well.

The cron job is still using gcj Java, not Sun, which may affect your
results. Cron jobs typically have a very different (much simpler)
environment than interactive sessions, which may account for the
difference between running a command in cron and running the same
command interactively.

I've figured it out. You can't have the java call directly in the crontab. You need to write a shell script that brings in the proper environmental variables and sets the PATH, and then that script makes the java call. Mine looks like this:

SHELL=/bin/bash

export JAVA_HOME=/usr/home/dspace/app/java
export ANT_HOME=/usr/home/dspace/app/ant
export MAVEN_HOME=/usr/home/dspace/app/maven
export CATALINA_HOME=/usr/home/dspace/app/tomcat
export DSPACE_HOME=/usr/home/dspace/app/dspace
export LD_LIBRARY_PATH=/usr/home/dspace/app/sqlplus
export TNS_ADMIN=/usr/home/dspace/app/sqlplus
export JAVA_OPTS="-Xmx2024M -Xms2024M -Dfile.encoding=UTF-8"

PATH=.:$JAVA_HOME/bin:$ANT_HOME/bin:$MAVEN_HOME/bin:$CATALINA_HOME/bin:$PATH:/usr/home/dspace/app/sqlplus
PATH=$PATH:$DSPACE_HOME/bin

/bin/date >> /tmp/mediafilter.log
/usr/home/dspace/app/dspace/bin/filter-media -v >> /tmp/mediafilter.log

It would be good to address this in the documentation (http://www.dspace.org/index.php?option=com_content&task=view&id=152 -- see "cron jobs")

Hola Sofia,

this largely depends on the version of DSpace you're using, 1.4.2 and
lower, 1.5 or 1.5.1?
