Installing on WebLogic

If you are using WebLogic as your application server, it is highly recommended to install DXP to a WebLogic Managed server. A managed server can start and stop DXP quickly and can be converted to a cluster configuration.

Prerequisites

Configure an Admin Server and a Managed Server following WebLogic’s documentation.

Liferay DXP/Portal requires a supported Java version to run. See JVM Configuration for recommended settings.

Download these files from the Help Center (subscription) or from Liferay Community Downloads:

  • DXP WAR file
  • OSGi Dependencies ZIP file
  • Dependencies ZIP file (DXP 7.3 and earlier)

Preparing the DXP WAR

  1. Unzip the DXP WAR file to an arbitrary location.

  2. Create a file called portal-ext.properties in the expanded WAR’s WEB-INF/classes folder.

  3. In the portal-ext.properties file, set the liferay.home property to your Liferay Home folder path. In WebLogic, [Liferay Home] is typically set to the domain’s folder (weblogic/domains), but you can use any local folder. For example,

    liferay.home=/full/path/to/your/liferay/home/folder
    
    Important

    The liferay.home directory must contain the Portal/DXP osgi/ directory.

  4. Package the portal-ext.properties in your DXP WAR file by expanding the DXP WAR file and copying the portal-ext.properties file into the WEB-INF/classes folder.

  5. Optionally, you can re-WAR the expanded DXP WAR. When you’re ready to deploy DXP, you can deploy it as an expanded archive or WAR file. In both cases, DXP reads the property settings once it starts up.

Note

If you need to update portal-ext.properties after DXP deploys, it is in the current location of the installed Liferay WAR under ROOT/WEB-INF/classes. WebLogic may move the WAR during installation.

Configuring WebLogic

Configuring WebLogic’s Node Manager

WebLogic’s Node Manager starts and stops managed servers.

If you’re running WebLogic on a UNIX system other than Solaris or Linux, use the Java Node Manager, instead of the native version of the Node Manager, by configuring these Node Manager properties in the domains/your_domain_name/nodemanager/nodemanager.properties file:

NativeVersionEnabled=false

StartScriptEnabled=true
Note

By default, the Node Manager uses SSL. If you want to disable SSL during development, set SecureListener=false in your nodemanager.properties file.

See Oracle’s Configuring Java Node Manager documentation for details.

Configuring WebLogic’s JVM

Configure the JVM and other options in a setUserOverridesLate WebLogic startup script and in your Managed Server UI.

  1. Create a setUserOverridesLate.sh script in [Your Domain]/bin.

  2. Add the following settings.

    export DERBY_FLAG="false"
    export JAVA_OPTIONS="${JAVA_OPTIONS} -Dfile.encoding=UTF-8 -Djava.net.preferIPv4Stack=true -Dlog4j2.formatMsgNoLookups=true -Duser.timezone=GMT -da:org.apache.lucene... -da:org.aspectj..."
    export JAVA_PROPERTIES="-Dfile.encoding=UTF-8 ${JAVA_PROPERTIES} ${CLUSTER_PROPERTIES}"
    export MW_HOME="[place your WebLogic Server folder path here]"
    export USER_MEM_ARGS="-Xms2560m -Xmx2560m -XX:MaxNewSize=1536m -XX:MaxMetaspaceSize=768m -XX:MetaspaceSize=768m -XX:NewSize=1536m -XX:SurvivorRatio=7"
    

    The DERBY_FLAG setting disables the WebLogic’s built-in Derby server—DXP does not require this server.

    JAVA_OPTIONS sets DXP’s UTF-8 requirement, Lucene usage, and Aspect Oriented Programming via AspectJ.

    JAVA_PROPERTIES also sets DXP’s UTF-8 requirement.

    Important

    DXP requires the application server JVM to use the GMT time zone and UTF-8 file encoding.

    Set MW_HOME to the folder containing the WebLogic server. For example,

    export MW_HOME="/Users/ray/Oracle/wls12210"
    

    The *_MEM_ARGS variables set DXP’s starting and maximum heap memory capacity.

  3. Make sure the Node Manager sets DXP’s memory requirements when starting the Managed Server. In the Admin Server’s console UI, navigate to the Managed Server where DXP is to be deployed and select the Server Start tab. Enter the following parameters into the Arguments field:

    -Xms2560m -Xmx2560m -XX:MaxNewSize=1536m -XX:MaxMetaspaceSize=768m -XX:MetaspaceSize=768m -XX:NewSize=1536m -XX:SurvivorRatio=7
    
  4. Click Save.

The Java options and memory arguments are explained below.

JVM Options Explained

OptionExplanation
-Dfile.encoding=UTF-8DXP requires UTF-8 file encoding.
-Djava.net.preferIPv4Stack=truePrefers an IPv4 stack over IPv6.
-Dlog4j2.formatMsgNoLookups=trueResolves a remote code execution (RCE) vulnerability. See LPS-143663 for details.
-Duser.timezone=GMTDXP requires the application server JVM to use the GMT time zone.

Memory Arguments Explained

Memory ArgumentsExplanation
-XmsInitial space for the heap.
-XmxMaximum space for the heap.
-XX:NewSizeInitial new space. Setting the new size to half of the total heap typically provides better performance than using a smaller new size.
-XX:MaxNewSizeMaximum new space.
-XX:MetaspaceSizeInitial space for static content.
-XX:MaxMetaspaceSizeMaximum space for static content.
-XX:SurvivorRatioRatio of the new space to the survivor space. The survivor space holds young generation objects before being promoted to old generation space.
Note

After installing DXP, these configurations (including these JVM options) can be further tuned for improved performance. Please see Tuning Liferay and Tuning Your JVM for more information.

Installing Dependencies

DXP depends on OSGi modules (OSGi Dependencies ZIP) and a database driver.

  1. Unzip the OSGi Dependencies ZIP file into the [Liferay Home]/osgi folder (create this folder if it doesn’t exist). Liferay’s OSGi runtime depends on these modules.

  2. The DXP 7.4+ WAR file includes drivers for MariaDB and PostgreSQL. Earlier DXP WARs don’t have them. If the 7.4+ WAR doesn’t have the driver for the supported database you’re using, download your database vendor’s JDBC JAR file and place it in the exploded DXP WAR’s WEB-INF/shielded-container-lib folder.

    See the compatibility matrix for a list of supported databases.

Note

A Hypersonic database is bundled with DXP and is useful for testing purposes. Do not use HSQL for production instances.

Note

For DXP 7.3 and earlier, unzip the Dependencies ZIP file to the WebLogic domain’s lib folder. Place your database vendor’s JDBC JAR file in that folder too.

Installing Elasticsearch

When you start Liferay, it installs and starts a default sidecar Elasticsearch server. When installing on WebLogic you should set up a remote Elasticsearch server right from the start. See Getting Started with Elasticsearch.

When Liferay DXP is configured (using .config files for the Elasticsearch connector) and started with Elasticsearch already configured and running, the connection to Elasticsearch is activated.

Connect to Database

DXP contains a built-in Hypersonic database for demonstration purposes, but it should not be used in production. Use a full-featured, supported database. See Configure a Database to set up your database.

Liferay DXP can connect to your database using DXP’s built-in data source (recommended) or a JNDI data source on your app server.

You can configure DXP’s built-in data source with your database the first time you run DXP by using the Setup Wizard. Or you can configure the data source in a portal-ext.properties file based on the Database Template for your database.

Otherwise, you can configure the data source in WebLogic.

  1. Get the JDBC JAR from your DXP WAR (7.4+) or from the database vendor, and copy it to the domain’s lib folder.

  2. Log in to the AdminServer console.

  3. In the Domain Structure tree, find the domain and navigate to ServicesJDBCData Sources.

  4. To create a new data source, click New.

  5. Enter the Name field with Liferay Data Source and the JNDI Name field with jdbc/LiferayPool.

  6. Select the database type and driver. For example, MySQL is MySQL’s Driver (Type 4) Versions:using com.mysql.cj.jdbc.Driver.

  7. Click Next to continue.

  8. Accept the default settings on this page and click Next to move on.

  9. Fill in the database information for the MySQL database.

  10. If using MySQL, add the text ?useUnicode=true&characterEncoding=UTF-8&\useFastDateParsing=false to the URL line and test the connection. If it works, click Next.

  11. Select the target for the data source and click Finish.

  12. Connect DXP to the JDBC data source. In the portal-ext.properties file (see above), enter the data source JNDI name. For example,

    jdbc.default.jndi.name=jdbc/LiferayPool
    

Connect to Mail Server

You can connect Liferay DXP to a mail server using its built-in mail session. Otherwise, you can use WebLogic’s mail session:

  1. Start WebLogic and log in to the Admin Server’s console.

  2. Select ServicesMail Sessions from the Domain Structure box on the left hand side of the Admin Server’s console UI.

  3. Click New to begin creating a new mail session.

  4. Name the session LiferayMail and give it the JNDI name mail/MailSession.

  5. Enter the Session Username, Session Password, Confirm Session Password, and JavaMail Properties fields as necessary for the mail server. See the WebLogic documentation for more information on these fields.

  6. Click Next.

  7. Choose the Managed Server where DXP is to be installed on, and click Finish.

  8. Shut down the Managed and Admin Servers.

  9. With the Managed and Admin servers shut down, add the following property to the portal-ext.properties file in Liferay Home:

    mail.session.jndi.name=mail/MailSession
    
Note

After DXP is deployed, the portal-ext.properties file can be found in the domain’s autodeploy/ROOT/WEB-INF/classes folder.

The changes take effect upon restarting the Managed and Admin servers.

Deploying DXP

Follow these steps to deploy the DXP WAR file:

  1. Verify that the designated Managed Server where you’re deploying DXP is shut down.

  2. In the Admin Server’s console UI, select Deployments from the Domain Structure box on the left hand side.

  3. Click Install to start a new deployment.

  4. Select the DXP WAR file or its expanded contents on the machine. Alternatively, upload the WAR file by clicking the Upload your file(s) link. Click Next.

  5. Select Install this deployment as an application and click Next.

  6. Select the designated Managed Server where you’re deploying DXP and click Next.

  7. If the default name is appropriate for the installation, keep it. Otherwise, enter a different name and click Next.

  8. Click Finish.

  9. After the deployment finishes, click Save if the configuration is correct.

  10. Start the Managed Server where you deployed DXP. DXP precompiles all the JSPs and then launches.

After deploying DXP, you may see excessive warnings and log messages such as the ones below, involving PhaseOptimizer. These are benign and can be ignored. You can turn off these messages by adjusting the app server’s logging level or log filters.
