Appendix: Metacat Properties ============================ The most dynamic Metacat Properties are managed using Metacat's Configuration Interface (see :doc:`configuration`). These properties, as well as other, rarely modified ones can be found in the metacat.properties file. For more information about the properties, click one of the following: * Server Properties * Application Properties * Database Properties * Authorization and Authentication Properties * XML/EML Properties Server Properties ----------------- All of Metacat's server properties are managed with the form-based configuration utility, though they can also be accessed More information on each is included below. Metacat Server Properties +---------------------------+------------------------------------------------------------------------------------------+------------------------+ | Property | Description | Example | +===========================+==========================================================================================+========================+ | .. _server-name: | | | | | | | | server.name | The network host name used to access Metacat. Note that this is not necessarily | knb.ecoinformatics.org | | | the physical name of the server running Metacat. The host name should not | | | | include the protocol prefix (http://). | | | | | | | | Default Value: localhost | | +---------------------------+------------------------------------------------------------------------------------------+------------------------+ | .. _server-httpPort: | | | | | | | | server.httpPort | The network port used to access Metacat for non-secure (standard) connections. | 80 | | | This is usually 80 if Apache Web server is running, and 8080 if Tomcat is running alone. | | | | | | | | Default Value: 80 | | +---------------------------+------------------------------------------------------------------------------------------+------------------------+ | .. _server-httpSSLPort: | | | | | | | | server.httpSSLPort | The network port used to access Metacat for secure connections. This is usually | 443 | | | 443 if Apache Web server is running, and 8443 if Tomcat is running alone. | | | | | | | | Default Value: 443 | | +---------------------------+------------------------------------------------------------------------------------------+------------------------+ Application Properties ---------------------- Metacat's application properties are described below. Properties that can only be edited manually in the ``metacat.properties`` file are marked. All others are managed with the properties configuration utility. +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | Property | Description | Example | +======================================+=============================================================================+===============================+ | application.metacatVersion* | The Metacat version number. It is set by the build engineer | 1.9.0 | | | at build time. Usually, the value should never be changed. | | | | | | | | Default Value: X.X.X (where X.X.X is the current version of Metacat) | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | application.metacatReleaseInfo* | Release information for display purposes. Typically the property | Release Candidate 1 | | | is set during the release candidate cycle to let users know which | | | | candidate they are downloading. | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _application.deployDir: | | | | | | | | application.deployDir | The directory where Web applications are deployed. Usually, the value | /usr/local/tomcat/webapps | | | is a directory named "webapps" in the Tomcat installation directory. | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _application.context: | | | | | | | | application.context | The name of the Metacat application directory in | knb | | | the deployment directory. 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. | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _index.context: | | | | | | | | index.context | The name of the Metacat index webapp in | metacat-index | | | the deployment directory. Most commonly, this | | | | is "metacat-index", but it can be changed if needed. | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _ui.context: | | | | | | | | ui.context | The name of the Metacat UI directory in | metacatui | | | the deployment directory. Often the UI is deployed | | | | as the ROOT webapp, in which case the property should be blank (""). | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _application.default-style: | | | | | | | | application.default-style | A custom Metacat Web skin usually associated with | default | | | an organizational theme. If your organization has no | | | | custom skin, leave the value as "default". | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _application.knbSiteURL: | | | | | | | | application.knbSiteURL | The main KNB website. | http://knb.ecoinformatics.org | | | | | | | Default Value: http://knb.ecoinformatics.org | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _application.datafilepath: | | | | | | | | application.datafilepath | The directory in which to store data files. The directory should | /var/metacat/data | | | be outside the Metacat installation directories so data files will not | | | | be lost when Metacat is upgraded. The data file directory must be | | | | writable by the user that starts Tomcat (and thus Metacat). | | | | | | | | Default Value: /var/metacat/data | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _application.inlinedatafilepath: | | | | | | | | application.inlinedatafilepath | The directory where inline data files will be stored. Inline | /var/metacat/inline-data | | | data files are created from data that is embedded in EML | | | | metadata. The directory should be outside the Metacat installation | | | | directories so data files will not be 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). | | | | | | | | Default Value: /var/metacat/inline-data | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _application.documentfilepath: | | | | | | | | application.documentfilepath | The directory where metadata files will be stored. | /var/metacat/documents | | | The directory should be outside the Metacat installation directories | | | | so document files will not be 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). | | | | | | | | Default Value: /var/metacat/documents | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _application.tempDir: | | | | | | | | application.tempDir | The directory where the Metacat data registry stores temporary | /var/metacat/temporary | | | files. The directory should not be the same as ``application.datafilepath`` | | | | or ``application.inlinedatafilepath`` (or any other persistent file path) | | | | because all files in this may be purged programmatically. The temporary | | | | file directory must be writable by the user that starts Apache. | | | | | | | | Default Value: /var/metacat/temporary | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ | .. _solr.homeDir: | | | | | | | | solr.homeDir | The directory where the Metacat index component stores the SOLR index. | /var/metacat/solr-home | | | The directory must be writable by the user that starts Tomcat. | | | | | | | | Default Value: /var/metacat/solr-home | | +--------------------------------------+-----------------------------------------------------------------------------+-------------------------------+ Database Properties ------------------- Metacat's database properties are described next.
