Prerequisites:

Cassanda-Tables
- Schema: https://fiznetz.fiz-karlsruhe.de/display/IEEpubFIZ/Data+Model
- Tables are created when calling de.fiz.oai.backend.utils.CassandraUtils.createKeyspace()
SOLR-Index
- Schema can be found in oai-backend-project, src/main/resources/solr or in Cortex-Project Cortex/conf/solr/oaiitems
Configuration
- fiz-oai-backend.properties. Can be found in https://dev.fiz-karlsruhe.de/stash/projects/FIZ-OAI/repos/fiz-oai-ddb-importer/browse/resources/conf/backend

Initial Data: create with project https://dev.fiz-karlsruhe.de/stash/projects/FIZ-OAI/repos/fiz-oai-ddb-importer , ddb_import/import.groovy

OAI-Frontend:

warfile, Java 11, Tomcat

Frontend needs own Tomcat because of startorder. First start OAI-Backend, then start OAI-Frontend

Configuration:

Apache-VHost:

Redirect to the Servlet: https://dev-ddb.fiz-karlsruhe.de/oai --> http://ddb-di-vm08:8080/oai/OAIHandler
Redirect to Stylesheet + Images: https://dev-ddb.fiz-karlsruhe.de/oai/docs --> http://ddb-di-vm08:8080/oai
Rewrite-Rule because of tailing slash (may not be behind Servlet-Path)

    <Location /oai >
      # OAI-Test in DI-Network
      AuthType Basic
      AuthName "Sie greifen auf ein Testsystem der DDB zu. Wenn Sie den Benutzernamen und das Passwort nicht kennen, dann sind Sie hier wahrscheinlich falsch."
      AuthUserFile "/etc/httpd/conf/htaccess"
      Require valid-user

      ProxyPass http://ddb-di-vm08:8080/oai/OAIHandler 
      ProxyPassReverse http://ddb-di-vm08:8080/oai/OAIHandler
    </Location>
    <Location /oai/docs >
      # OAI-Test in DI-Network
      AuthType Basic
      AuthName "Sie greifen auf ein Testsystem der DDB zu. Wenn Sie den Benutzernamen und das Passwort nicht kennen, dann sind Sie hier wahrscheinlich falsch."
      AuthUserFile "/etc/httpd/conf/htaccess"
      Require valid-user

      ProxyPass http://ddb-di-vm08:8080/oai
      ProxyPassReverse http://ddb-di-vm08:8080/oai
    </Location>

    RewriteCond %{REQUEST_URI} ^/oai.*
    RewriteRule ^(/oai)/+$ $1 [R=301,L]

Stylesheets + related Images are located in https://dev.fiz-karlsruhe.de/stash/projects/FIZ-OAI/repos/fiz-oai-ddb-importer/browse/resources/docs/frontend

Edit oai2.xsl, adapt links to images (3 Images, just below <html>-element) , Put Images into the same Folder as the Stylesheet.
Put Stylesheet oai2.xsl and Images into webapps/oai/ and reference it in the Configuration (/oai/docs/oai2.xsl)
prepared xsl + images for the server is located in <tomcat_root>/conf/docs. Just copy to <tomcat_root>/webapps/oai after redeploy of App

Configuration (https://dev.fiz-karlsruhe.de/stash/projects/FIZ-OAI/repos/fiz-oai-ddb-importer/browse/resources/conf/frontend/oaicat.properties )

Set OAIHandler.baseURL (zB dev-ddb.fiz-karlsruhe.de/oai)
Set link to the Stylesheet as OAIHandler.styleSheet
