CLAIMS Direct Web Services (CDWS) are a collection of services built on the Perl Cataylst framework. The application runs as a virtual host and a typical deployment would be in combination with Apache httpd.

On-site installations of CDWS have a very limited set of services available, namely /text and, if the optional SOLR index is installed, /search. All other service interfaces must be called remotely to https://cdws21.ificlaims.com. Please contact support@ificlaims.com for further details.

Configuration

The main configuration files for CDWS will reside in /opt/fv/lib/perl5/Alexandria/CDWS and are:

alexandria-cdws-apache.conf
The virtual host definition. Here you can change the Port httpd listens on for the CDWS application.
alexandria-cdws.conf
The main application configuration file.

The main configuration file (alexandria-cdws.conf) is broken into the following sections:

Global Parameters
Authentication Plugins
Database Models

Global Parameters

CLAIMS Direct Web Services

The following table explains the global parameters and values in alexandria-cdws.conf:

Parameter	Default Value	Custom Configurable	Description
name	alexandria-cdws	No	The package name
remote	1	No	This variable guides code logic depending on the CLAIMS Direct installation being remote (on-site) or Primary
log_statistics_database	1	Yes	If requests should be logged into the `admin.t_user_statistics` table
log_statistics_error_log	1	Yes	If requests should be logged into the httpd error_log
index_version	21	Yes	The index version. Although this variable is configurable, it shouldn't need to be changed.
enable_ip_authentication	1	No	This parameter activates code that allows IP authentication
secure	0	Yes	Change this parameter to 1 to broadcast to CDWS application that the web server is running under SSL

CLAIMS Direct Web Interface

The following table explains the global parameters and values in alexandria-cdwi.conf:

Parameter	Default Value	Custom Configurable	Description
name	alexandria-cdwi	No	The package name
enable_log4js	0	Yes	Enable or disable popup javascript logging (very useful for debugging)
remote	1	No	This variable guides code logic depending on the CLAIMS Direct installation being remote (on-site) or Primary
cdwi version	2.1	No	Version of CLAIMS Direct Web Interface
index_version	21	Yes	The index version. Although this variable is configurable, it shouldn't need to be changed.
enable_ip_authentication	0	No	This parameter activates code that allows IP authentication
secure	0	Yes	This is under apache with SSL
location of transient data	transient_data_directory /tmp	Yes	Storage directory for temporary data. This is configurable but `/tmp` is recommended.
maximum number of results to report / extract	result_set_export_max 30000	No	The maximum number of records which can be reported or extracted

Authentication Plugins

The plugins section contains the directives for authentication. As this uses database model definitions appearing later in the file, this directive should not be modified.

Database Models

The following table lists the database models defined, along with their function. Italic rows are not available with on-site installations:

Database Model	Variables	Function	Notes
`Model::DBIx::Connector`	none	Main PostgreSQL interface
`Model::Custom`	host	Interface into the reporting database	This interface enables CSV reporting. This reporting module is superseded by `Model::Report` defined below.
`Model::Web`	host	Deprecated (was earlier web sessions interface)
`Model::CDWS`	server address	Server URL
`Model::Users`	host	Interface into the users database supporting the authentication plugin
`Model::Report`	host solrurl storage	Interface into the users database	This interface supports v2.x reporting for both XML and CSV. To use this interface effectively, the optional SOLR component must be installed locally.
`Model::Session`	host	Interface into the users database	This interface supports the `Sessions` web services (experimental)
`Model::DWH::Standard` `Model::DWH::Premium` `Model::DWH::Premium::Plus`	host	Interface into the main `alexandria` XML data warehouse	This interface supports a variety of web services, including `/text`
`Model::Attachments`		Interface into the attachments database	Unavailable with on-site installations
`Model::Inventory`		Interface into the raw data warehouse	Unavailable with on-site installations
`Model::MSSQL`		Interface into the level I data warehouse	Unavailable with on-site installations
`Model::Solr::Standard` `Model::Solr::Premium` `Model::Solr::Premium::Plus`	base server collection params	Main interfaces into the SOLR index	Available only with optional SOLR installation
`Model::Solr::Attachments`		Interface into attachments index	Unavailable with on-site installations
`Model::Solr::PITR`		Interface into PITR reporting index	Unavailable with on-site installations
`Model::Zabbix`		Interface into systems monitoring	Unavailable with on-site installations

Apache httpd Integration

alexandria-cdws-apache.conf Installation

To enable CDWS to run under httpd, the virtual host definition file alexandria-cdws-apache.conf must be either copied or linked into /etc/httpd/conf.d

# link (recommended)
cd /etc/httpd/conf.d && ln -s /opt/fv/lib/perl5/Alexandria/CDWS/alexandria-cdws-apache.conf z01.conf
# or copy
sudo cp /opt/fv/lib/perl5/Alexandria/CDWS/alexandria-cdws-apache.conf /etc/httpd/conf.d/z01.conf

Apache httpd Directory Permissions

Depending on distribution, you may also need to adjust the permissions to the root Directory in httpd.conf

<Directory />
    AllowOverride none
    Require all granted
</Directory>

Enable, Start, and Stop httpd

sudo systemctl enable httpd.service
sudo systemctl start httpd.service
# stop
# sudo systemctl stop httpd.service
