Metacat Properties File

Back | Home | Next

Metacat Server has properties that are stored in two general locations. Global properties are held in:

<CONTEXT_DIR>*/WEB_INF/metacat.properties.

Skin specific properties are set on a per-skin basis in:

<CONTEXT_DIR>*/WEB_INF/style/skins/<SKIN_NAME>/<SKIN_NAME>.properties

The most dynamic properties are modified using the internal Metacat configuration utility . However, it may be necessary to manually edit a configuration file to update more static values.

The list of properties shown on this page gives the following information about each property:

(* CONTEXT_DIR refers to the directory where the Metacat application code lives. This is a combination of the web application directory and the metacat context directory. This usually looks something like /usr/local/tomcat/webapps/knb. However, your webapps directory could be somewhere besides the tomcat directory and your context could be something other than knb.)

Global Metacat Properties - (metacat.properties)


server.name

Default Value:

localhost

Set Method:

Configuration Utility

Description:

The network host name that will be used to access Metacat. Note that this is not necessarily the physical name of the server running Metacat. The host name should not include the protocol prefix (http://).

Example:

knb.ecoinformatics.org

server.httpPort

Default Value:

80

Set Method:

Configuration Utility

Description:

The network port that will be used to access Metacat for non-secure (standard) connections. This is usually 80 if Apache web server is running (typical install), and 8080 if Tomcat is running alone, but both Apache and Tomcat could have been configured to listen on alternate ports.

Example:

80

server.httpSSLPort

Default Value:

443

Set Method:

Configuration Utility

Description:

The network port that will be used to access Metacat for secure connections. This is usually 443 if Apache web server is running (typical install), and 8443 if Tomcat is running alone, but both Apache and Tomcat could have been configured to listen on alternate ports.

Example:

443

Default Value:

1.9.0

Example:

1.9.0

application.deployDir

Default Value:

(none)

Set Method:

Configuration Utility

Description:

The directory where web applications are deployed. Many times this is in a directory named "webapps" in the Tomcat installation directory. However, Tomcat may be configured to look in a different directory.

Example:

/usr/local/tomcat/webapps

application.context

Default Value:

(none)

Set Method:

Configuration Utility

Description:

Applications run in individual directories in the applicaton deployment directory. The name of the application directory is the application context. This corresponds to the first part of the war file name (the part before .war). Most commonly, this is "knb", but it can be changed to other things.

Example:

knb

application.default-style

Default Value:

default

Set Method:

Configuration Utility

Description:

There are some custom web skins available in Metacat. Typically these are associated with an organizational theme. If there is not a custom skin for your organization, you should leave it as "default".

Example:

default

application.knbSiteURL

Default Value:

http://knb.ecoinformatics.org

Set Method:

Configuration Utility

Description:

The KNB site to redirect to.

Example:

http://knb.ecoinformatics.org

application.datafilepath

Default Value:

/var/metacat/data

Set Method:

Configuration Utility

Description:

This is the directory whera data files will be stored. This should be some directory outside the Metacat installation directories so data files will not get lost when Metacat is upgraded. The data file directory must be writable by the user that starts Tomcat (and thus Metacat).

Example:

/var/metacat/data

application.inlinedatafilepath

Default Value:

/var/metacat/inline-data

Set Method:

Configuration Utility

Description:

This is the directory where inline data files will be stored. Inline data files are created from data that is embedded in EML metadata. This should be some directory outside the Metacat installation directories so data files will not get lost when Metacat is upgraded. For clarity of data, this should probably not be the same as application.datafilepath. The data file directory must be writable by the user that starts Tomcat (and thus Metacat).

Example:

/var/metacat/inline-data

application.documentfilepath

Default Value:

/var/metacat/documents

Set Method:

Configuration Utility

Description:

This is the directory where metadata document files will be stored. This should be some directory outside the Metacat installation directories so document files will not get lost when Metacat is upgraded. For clarity of organization, this should probably not be the same as application.datafilepath or application.inlinedatafilepath. The data file directory must be writable by the user that starts Tomcat (and thus Metacat).

Example:

/var/metacat/documents

application.tempDir

Default Value:

/var/metacat/temporary

Set Method:

Manual

Description:

This is the directory that Metacat data registry uses to store temporary files. This should not be the same as application.datafilepath or application.inlinedatafilepath (or any other persistant file path) since all files in this may be purged programatically. The temporary file directory must be writable by the user that starts Apache.

Example:

/var/metacat/temporary

application.cgiDir

Default Value:

/cgi

Set Method:

Manual

Description:

This is the directory that is configured in Apache web server to point to Metacat cgi executables. The directory is given relative to the Metacat context directory since the Metacat cgi scripts are installed with the application code. For example, if Metacat is installed in /usr/local/tomcat/knb, then an application.cgiDir of /cgi would point to
    /usr/local/tomcat/knb/cgi-dir

Example:

/cgi-bin
