How do I work on larger collections without running our of memory ?

The start batch files and sh files for RcTools have a setting for your Java maximum memory.  You can make this larger for your collections by adjusting the -Xmx setting.  The default is -Xmx512m for 512 megabytes of memory.  If your tool reports an out of memory error you can increase this setting to available memory in the machine less start up.  So a machine with 2 gigabytes of ram could easily  be set to -Xmx1024m for this setting.

You can find the batch files under your installation directory.  For Windows the default location is C:\Program Files\RcTools\bin\   and on   Mac OSx  installs the default is the  /Applications/RcTools/bin directory.

Harvard's JHOVE and ResCarta Data

Jhove invalidates some ResCarta accepted tiff images.

If you are running the Harvard file validator called JHOVE and receive the following error on tiff images in your ResCarta collection.files

“Status: Not well-formed”

Add the following line to your configuration file (jhove.conf) in your home directory or create a custom configuration file with this line and use the -c parameter with JHOVE.

<param>byteoffset=true</param>

Change your tiff module from...

<module><class>edu.harvard.hul.ois.jhove.module.TiffModule</class></module>

 to the following...

<module><class>edu.harvard.hul.ois.jhove.module.TiffModule</class>

<param>byteoffset=true</param></module>

After this parameter has been added you will not longer get a “Not well formed” message but you will get an informational message about the values that may not be word aligned. These images have addition tags not modified by the ResCarta data conversion tool and are acceptable TIFF images. The images will then be noted as " Well-Formed and valid" by JHOVE with an informational message like the one below...

TIFF-hul

InfoMessage: Value offset not word-aligned: 493

JHOVE and the Unknown TIFF IFD tags 5687,5688 and 5689.

These tags are the location of the ResCarta metadata which are defined in the ResCarta specifications. These tags were declared PUBLIC when regisstered with the TIFF tag registry with Adobe Corporation. 5697 = MODS XML data, 5688 = Word data, 5689 = Word location and font data.

InfoMessage: Unknown TIFF IFD tag: 5687

InfoMessage: Unknown TIFF IFD tag: 5688

InfoMessage: Unknown TIFF IFD tag: 5689

I can't see my ResCarta-Web site from outside my institution?

The default port for the Apache Tomcat service is 8080.  This port is defined for HTML traffic along with the more often used port 80.  On many campus networks all high ports are blocked.   This means the high HTML port of 8080 is also blocked.

If your server is not using port 80 for any other server (APACHE, IIS), you can change the default port of your Apache Tomcat server to port 80 by editing the  server.xml file located in the conf directory. Look for the connector which should be set to 8080. It should be like the following...

<Connector port="8080" protocol="HTTP/1.1"

connectionTimeout="20000" redirectPort=

"8443" />

Change the 8080 to 80 and restart your Tomcat service.

 <Connector port="80" protocol="HTTP/1.1"connectionTimeout="20000"

redirectPort="8443" />

 If your server is also running IIS and it is located on port 80,  your Tomcat service will not start.  To run both IIS and Tomcat and use a sinlgle port 80 will require a more extensive configuration of both IIS and tomcat.
