New Functionality and Changes Introduced with FICO Xpress Executor 4.50

This section describes the new features and changes introduced with FICO Xpress Executor 4.50.
Important Insight 4.50 is NOT directly backwards compatible with previous versions of Insight. Insight 4.50 executes Mosel 5 models. Some model changes are required to upgrade an existing app to be compatible with Insight 4.50 and Mosel 5.

For more, see the migration guide Upgrading from Mosel 4 to Mosel 5 (file docs/mosel/upgrade.pdf in the Xpress installation).

  • Mosel 5 and Xpress 8.6 support
    • Support for new Mosel 5 models
    • mminsight is now a dynamic package
    • Existing apps must be recompiled in Mosel 5, execution of Mosel 4 models is no longer supported
    • App requiring an upgrade are highlighted on the Insight home page
    • See migration guide for further details
  • Java 11
    • Xpress Insight now requires Java 11, Java 8 is no longer supported
    • Xpress Insight supports OpenJDK 11 and Oracle Java 11
    • Xpress Insight installers configure the mosjvm module to use Java 11, see xpressmp/bin/xprmsrv.cfg
    • Server updated to use WildFly 15 for Java 11 compatibility
  • Java execution from Mosel
    • Execution Worker installation configures Mosel to use Java 11 for Java execution, see xpressmp/bin/xprmsrv.cfg
    • Default configuration no longer restricts Java execution by package name. User supplied java code executes in the security manager sandbox
  • LDAP full integration mode
    • LDAP integration can now optionally be configured so that users are created or updated based on their LDAP records during logon
    • Users are granted access to Insight and Tableau by defining LDAP groups which indicate access should be granted. Users attempting to access insight are checked for membership of these groups during logon
    • Authority Groups and Applications can be mapped to LDAP groups. Users which are members of the LDAP groups are granted the corresponding Authority Groups and app membership on logon
    • No impact on existing installations using LDAP. Integration defaults to partial mode which is backwards compatible (authentication only)
    • See the updated Insight Administrator Guide for details on how to configure LDAP
  • Tableau 2018.3 and 2019.1 support.
    • Tableau 2019.1 is the recommended Tableau version for Insight 4.50
    • As per Tableau support policy, we no longer support Tableau versions 10.1 and earlier
  • User administration rights are no longer required to manage execution workers or system configuration
  • VDL 4.5
    • Project references renamed to App
  • Database server upgraded to PostgreSQL 9.5.16 on Windows. The Insight Installation guide for Linux gives details on how to install the latest PostgreSQL 9.5 release
Fixed in Insight 4.50.0
