RapidMiner Server Settings and Services

To change the hostname settings, follow these steps:

1. Edit the file configuration/standalone.xml in your RapidMiner Server home directory.

2. Locate the tags configuring the interface:

        <interface name="public">
            <inet-address value="${jboss.bind.address:127.0.0.1}">
        </interface>         
   

3. Edit the bind address (the IP address after the colon, 127.0.0.1 in the above example) as required. You can enter a hostname instead of an IP address if desired.

4. Save the file and restart RapidMiner Server.

To change the port settings, follow these steps:

1. Edit the file configuration/standalone.xml in your RapidMiner Server home directory.

2. Locate the tags configuring the socket bindings (these define the HTTP and HTTPS ports):

    <socket-binding name="http" port="8080"/>
   
    <socket-binding name="https" port="8443"/>
   

3. Edit the port numbers as required.

4. Save the file and restart RapidMiner Server.

Note: On Linux, you must be running as root to change port numbers below 1024 (this includes the standard HTTP(S) ports 80 and 443).

If you use single sign on in RapidMiner Server, you must change the HTTP header size. This is because the Kerberos token string is usually quite long, exceeding the default header size.

To change the header size:

1. Edit the file configuration/standalone.xml in your RapidMiner Server home directory.

2. Locate the extensions tag definitions (they are most likely at the beginning of the file):

    <extensions>
        .
        .
        .
    </extensions>
   

3. Immediately after the extensions tag (do not modify the extensions tag), add the following system-properties tag, where value defines the maximum URL length:

    <system-properties>
           <property name="org.apache.coyote.http11.Http11Protocol.MAX_HEADER_SIZE" value="65535"/>
    </system-properties>
   

4. Save the file and restart RapidMiner Server.

If you did not configure the SMTP server during installation or need to change the outgoing email address, you can do it by editing the standalone.xml configuration file.

1. Edit the file configuration/standalone.xml in your RapidMiner Server home directory .

2. Locate the mail subsystem element, for example:

    <subsystem xmlns="urn:jboss:domain:mail:1.0">
        <mail-session jndi-name="java:/Mail" debug="false" from="user@localhost.com">
            <custom-server name="smtp" outbound-socket-binding-ref="mail-smtp">
                <login name="username" password="password"/>
            </custom-server>
            <!-- pop3-server outbound-socket-binding-ref="mail-pop3"/ -->
        </mail-session>
    </subsystem>
   

3. Modify the from, username, and password fields as required. Be certain that the from field is not blank (otherwise sending emails will not work). The from and username fields should not be the same, unless required to be by your email provider. The from value cannot be an arbitrary address, it must be a registered alias that username can send as.

4. Locate the outbound socket element for example:

    <outbound-socket-binding name="mail-smtp">
        <remote-destination host="localhost" port="25"/>
    </outbound-socket-binding>
   

5. Modify the host and port fields as required.

6. Save the file and restart RapidMiner Server.

To verify the settings:

1. Log in to RapidMiner Server as administrator.

2. Go to Administration > System Settings. Click on the Email Configuration tab.

3. Enter an email address and click the Send test mail button. If the email address you entered does not soon receive an email (and you checked any junk and trash folders), consult the log files.

   

   Note: In the Email Configuration tab you may see the message “The property com.rapidanalytics.mail.jndi_name is undefined. Assuming JNDI name ‘java:/Mail’. No mail session is configured under this JDNI name.”

   JNDI is the Java Naming and Directory Interface, used, for example, if RapidMiner Server runs on a JBoss shared with other applications. Typically this message can be ignored. If you changed the JNDI name in the standalone.xml configuration file, you can configure the system settings of your RapidMiner Server and set the com.rapidanalytics.mail.jndi_name property to the new JNDI name.

RapidMiner Server version 2.5 improves repository performance when storing large example sets. To include this improvement when performing an EAR upgrade:

1. Edit the file configuration/standalone.xml in your RapidMiner Server home directory.

2. Locate the datasource subsystem element, for example:

    <datasource jta="true" jndi-name="java:/jdbc/RapidAnalyticsDS" pool-name="RapidAnalyticsDS" enabled="true" use-java-context="false" use-ccm="true">
   
    <connection-url>jdbc:mysql://localhost:3306/rapidminer_server</connection-url>
   
    <driver>mysql-connector-java-5.1.31.jar</driver>
    .
    .
    .
    </datasource>
   

3. Add the following line to the <datasource></datasource> element:

    <connection-property name="rewriteBatchedStatements">true</connection-property>
   

4. Save the file and restart RapidMiner Server.

1. In the RapidMiner Server installation directory, open bin/standalone.conf.bat.

2. Change the JAVA_HOME location by changing the following line, where JRE7 is the updated Java folder:

   set "JAVA_HOME=C:\Program Files\Java\<jre7>

3. Save the file and restart RapidMiner Server.

1. In the RapidMiner Server installation directory, open bin/standalone.conf.

2. Change the JAVA_HOME location by changing the following line, where JRE7 is the updated Java folder:

   JAVA_HOME="/opt/java/<jre7>"

3. Save the file and restart RapidMiner Server.

1. Starting from your RapidMiner Server home directory , navigate and open the file configuration/max-memory.conf.

2. The file should contain a number followed by the letter M. This sequence signifies the maximum amount of memory in MB that Rapidminer Server may use. For example the value 8192M means that RapidMiner Server may allocate up to 8,192 MB of RAM.

3. To modify this setting simply replace the number with the desired amount of memory in MB, that RapidMiner Server may use.

4. Save the file and restart RapidMiner Server.
