Large Files on a Single Node Fedora 4 Installation

...

Because of https://issues.jboss.org/browse/MODE-2103 for large file ingests only the single-file configuration can be used.

Setting the Java Property fcrepo.modeshape.configuration to classpath:/config/single-file/repository.json and allowing the heap to grow up to 2gb is required.

Example

Running Fedora 4 for large file ingests in Tomcat7 

CATALINA_OPTS="-Xmx1024m -XX:MaxPermSize=256m -Dfcrepo.modeshape.configuration=classpath:/config/single-file/repository.json" bin/catalina.sh run

Tip

Using the single-file configuration ingest and retrieval of files up to the size of 300 GB using Fedora 4's REST API were tested successfully. The files were ingested sequentially, retrieved and a bitwise comparison with the original data has been performed. Larger sizes have not been tested, due to HDD size limitations.
