    • Adapt the paths to future digdash directories:
      Ddigdash.properties.path=E:\digdash\digdash.properties
       
    • To ensure that special characters are taken into account, add the parameter -Dfile.encoding=UTF-8 to the end of the JAVA_OPTS variable as below:

    • Add the parameters --add-opens=java.base/java.nio=org.apache.arrow.memory.core,ALL-UNNAMED --add-opens=java.base/sun.security.ssl=ALL-UNNAMED --add-opens=java.base/sun.security.util=ALL-UNNAMED in Java 9 options.

     

❗Important: Do not forget to increase the tomcat memory
Enter the same value in the “Initial memory” and “Maximum memory pool” fields in MB (example: “3000”)

Editing the server.xml file

  1. Open the server.xml file located in the \Apache Software Foundation\Tomcat 10.1\conf directory.
  <Connector port="8080" protocol="HTTP/1.1"
                connectionTimeout="20000"
                maxConnections="30000"
                maxCParametersCount="100000"
                maxThreads="10000" maxPostSize="62914560"
              redirectPort="8443" compression="on" />
  1. Change the path of the webapps to deploy.
<Host name="localhost"  appBase="E:/digdash/webapps/default"
            unpackWARs="true" autoDeploy="true">
      <Alias>digdash.client.com</Alias>

 

  1. Add the log valve and then, the securing valve.
<Valve className="org.apache.catalina.valves.ErrorReportValve" showReport="false" showServerInfo="false" /> 

❗ In case of SSO authentications (SAML or OpenID), the valve below must be placed before the SSO valve.

<Valve className="org.apache.catalina.valves.RemoteIpValve"
                internalProxies="127\.0\.[0-1]\.1"
                remoteIpHeader="X-Forwarded-For"
                requestAttributesEnabled="true"
                protocolHeader="X-Forwarded-Proto"
                protocolHeaderHttpsValue="https"/>

Editing the context.xml file

  1. Open the context.xml file located in the \Apache Software Foundation\Tomcat 10.1\conf directory.
  2. Add the following XML tag in the Context section:
<Resources cachingAllowed="true" cacheMaxSize="500000"/>
