Production Ready Domain

Since Payara Server 4.1.153

Payara Server comes with a default domain, domain1, which has been inherited from GlassFish. This domain (and its accompanying template) has not been modified in any way for Payara Server. The default domain is not, however, designed to be run in production but to be a usable example for development and testing purposes.

Since the creation of domain1 in GlassFish, there have been changes in how the server is used, along with the changes implemented by the Payara development team. To better highlight these changes and new features, the payaradomain was created.

Usage

payaradomain is located in the default directory for domains ${PAYARA_HOME}/glassfish/domains/, alongside domain1. This means it can be used as-is by simply naming the domain after running the start-domain subcommand and without specifying the domain directory location:

asadmin> start-domain payaradomain

Alternatively, many Payara Server users completely delete existing domains and recreate their own domains with custom settings. payaradomain can be used here too, since the domain is also provided as a template in the ${PAYARA_HOME}/glassfish/common/templates/gf directory. You will need to specify the full path to the location of the template jar as follows:

asadmin> create-domain --template ${PAYARA_HOME}/glassfish/common/templates/gf/payara-domain.jar myNewPayaraDomain

Differences to domain1

The configuration of payaradomain has been made with production in mind, so there are a number of differences when compared to domain1 which are listed below. Not all of these will be wanted for development environments, but all are good practice for production domains.

Differences in Server Configuration

  1. Autodeployment has been disabled.

    • Payara Server comes with a deployment scanner. This is a security risk for production, so it is disabled by default in the domain.xml.

  2. Dynamic application reloading is disabled.

    • For the same reason as above, this is disabled by default in the domain.xml

  3. Dynamic reloading of JSP pages in default-web.xml is disabled.

    • The <init-param> setting reload-interval in the default-web.xml has been set to a value of -1 so that it is disabled.

  4. The EJB container max-pool-size has been set to 128

  5. The max-thread-pool-size setting for thread-pool-1 has been increased to 250.

  6. File caching has been enabled for both default HTTP listeners (http-listener-1 and http-listener-2).

  7. Isolated classloading has been enabled by default at the server level.

    • The property fish.payara.classloading.delegate has been set to false.

  8. A default transaction timeout of 300 seconds has been added for xa and non-xa transactions.

  9. Default group-to-role mapping is enabled.

  10. The maximum size for the thread pool http-thread-pool has been increased from 5 to 50.

Differences in JVM Options

With the aim of payaradomain being to target production, payaradomain has JVM options specifically configured for usage on JDK 8. Since JDK 7 has reached its end-of-life, it is therefore a security risk to run a JVM lower than version 8 in production. However, payaradomain can be configured to run on JDK 7 if necessary by editing the JVM options.

The following JVM options only appear in payaradomain:

  • -XX:+UseG1GC

  • -XX:+UseStringDeduplication

  • -Xmx2g

  • -Xms2g

The following JVM options only appear in domain1:
