Each of these deployment approaches has its own way of setting System Properties.

Tomcat 7

On Debian Linux systems, the typical way of setting System Properties is to update the following file:

Additional information regarding the configuration of System Properties in Tomcat 7 can be found here.found here.

Windows notes

Alternatively on Windows systems you can set the following file:

CATALINA_BASE/bin/setenv.bat (windows)

Within that file, new properties can be added per the example below:

set CATALINA_OPTS=%CATALINA_OPTS% -Dfcrepo.ispn.repo.CacheDirPath=F:\fedora\cache

Caused by: org.fusesource.leveldbjni.internal.NativeDB$DBException: IO error: F:\apache-tomcat-7.0.50-windows-x64\apache-tomcat-7.0.50\bin\fcrepo4-data\fcrepo.ispn.repo.CacheDirPath\data\MANIFEST-000002: The handle is invalid.

Additional information regarding the configuration of System Properties in Jetty 9 can be found here.

Windows notes

Alternatively on Windows systems you can set the following file:

{JETTY_DIST}/start.ini

Within that file, new properties can be added per the example below:

--exec
-Dfcrepo.home=/mnt/fedora-data

Maven jetty:run

System Properties can be set when using the Maven jetty:run plugin by passing them per the example below:

...

java -Dfcrepo.home=/mnt/fedora-data -jar fcrepo-webapp-jetty-console.war

Configuration Elements

There are a number of configuration elements that can be optionally be set when starting the Fedora 4 web-application. No configuration elements are required to be set, as they all default values (noted below within brackets: <>).

fcrepo.home=<cwd/fcrepo4-data>

This can be set to a path (relative to the current working directory or absolute) to which Fedora repository content will be written.  Any of the Modeshape and Infinispan configuration options below will default to being within this folder if unset or if set to a relative path.  If unset, content will be put in the "fcrepo4-data" directory within the current working directory.

fcrepo.modeshape.configuration=<classpath:/config/repository.json | file:/path/to/repository.json>

This specifies the configuration for the underlying Modeshape repository. See other available options for this value within the source tree. The default file is located within the WAR file under WEB-INF/classes/config.

fcrepo.infinispan.cache_configuration=<config/infinispan.xml>

This specifies the underlying Infinispan cache configuration. This value has a tested default set in the modeshape.json file mentioned above; and therefore, can usually be left as is. The default file is located within the WAR file under WEB-INF/classes/config.

java.io.tmpdir=</tmp on Linux, $TMPDIR on MacOSX, and %TEMP% on Windows>

This specifies the directory for writing temp files.  You may need to set this property to a larger disk/filesystem to upload large files, particularly on Linux where /tmp is sometimes on a small partition.

Modeshape and Infinispan

The Modeshape and Infinispan configurations mentioned above have a number of more detailed configuration elements that can optionally be set. To see exactly which elements are available to be set, inspect the repository.json and infinispan.xml files specified above. Those files can be browsed in the source tree in:

• the ModeShape configuration directories and,
• the Infinispan configuration directories.

Some common elements for Modeshape and Infinispan relate to the directories in which application information is persisted. As mentioned above, if no fcrepo.home property is set then application information will be persisted under the directory "fcrepo4-data" in the application's current working directory. There will then be several directories within "fcrepo4-data" that are named by default with the name of the property that can be set to configure each of those directories.

Below are some common examples of these directories:

fcrepo.ispn.repo.CacheDirPath

Contains the serialized repository resource properties.

fcrepo.modeshape.index.location

Contains the internal Lucene index used by Modeshape/Admin Search.

fcrepo.activemq.dir

Contains the reliable messaging information maintained by ActiveMQ.

com.arjuna.ats.arjuna.common.ObjectStoreEnvironmentBean.default.objectStoreDir
com.arjuna.ats.arjuna.objectstore.objectStoreDir

Contain JBoss JTA transaction engine artifacts.
