Review the Prerequisites for an Oracle Mart

Before you install the Mart components, help ensure that the minimum system requirements that are outlined in this topic are met.

You can use any of the following combinations to install erwin Data Modeler, the Mart database, and the MartServer application:

  • Install erwin Data Modeler, the Mart database, and the MartServer application on the same computer.
  • Install erwin Data Modeler, the Mart database, and the MartServer application on different computers.
  • Install erwin Data Modeler and the Mart database on one computer, and install the MartServer application on a different computer.
  • Install erwin Data Modeler on one computer, and install the Mart database and the MartServer application on a different computer.

Ensure that you always install the MartServer application on Windows operating system.

System requirements for installing the MartServer application

Hardware requirements (based on physical hardware performance, not a virtual environment):

Hardware requirements (based on physical hardware performance, not a virtual environment):

  • 2 GHZ or higher dual core processor
  • 4 GB RAM (8 GB or more for large marts)
  • 4 GB of disk space or more as required to support your specific mart

Operating system:

  • Microsoft Windows 7 SP1
  • Microsoft Windows 8.1
  • Microsoft Windows 10
  • Microsoft Windows Server 2008 R2 SP1
  • Microsoft Windows Server 2012, R2
  • Microsoft Windows Server 2016
  • Microsoft Windows Server 2019
  • Microsoft .NET Framework 4.0 and above
  • All current Microsoft Windows critical updates are applied

Database:

  • The Mart Server can use a standalone or can share an existing database server for an Oracle 11g, 12c, or the certified versions 12c R2, 18c, and 19c database. If you are using Oracle 12c, you can use a pluggable database.
  • To create the Mart, you must be the database schema owner user and you must have the DBA role in the target database on the Oracle server. The DBA role is required for the user who is specified in the Configure MartServer dialog. If the DBA privilege of this user is revoked, then erwin DM users will not be able to save model changes to the Mart.
  • (Optional) You have modified the following parameters in the initialization file (InitSID.ora): 
    Remote_OS_Authent=T

    OS_Authent_Prefix=TRUE
  • (Optional) To use the Korean language with the Mart database, use KO16MSWIN949 or AL32UTF8 character set depending on your operating system language pack. For more information, see the Oracle documentation.

erwin Mart Administrator web client:

Supported browsers:

  • Microsoft Internet Explorer v10 or newer
  • Mozilla Firefox v30 or newer
  • Google Chrome v30 or newer
  • Apple Safari 6 or newer

Note: Ensure that your screen resolution is 1024 x 768 or higher. If your screen resolution is less than the minimum supported, some portions of the screen will not be visible.

Other requirements

Help ensure that the following additional requirements are met:

  • If you want to use Microsoft IIS as the web server, you have configured it.
  • The DBMS is installed and prepared for creating the Mart Database.
  • The Mart database is created. At least one user with administrator privileges is present. You have run the initial queries on the Oracle database. For more information about the initial queries, see the Implementation Guide.
  • If you want to add Windows Group users as Mart users, you have the Active Directory Server details.

    Note: You can add Windows Group users as normal Mart users, but not as Mart administrators. A Mart administrator must be a server or Windows user.

Important disclaimer notice on all requirements

  1. The requirements that are mentioned previously define the minimum requirements which permit the application to run with reasonable performance based on a small business use case scenario. The actual requirements for an enterprise-wide use case based on larger models and configurations require significantly greater resources to obtain acceptable performance.
  2. These requirements are based on actual physical hardware (no virtual environment) and the following assumptions:
    • Minimal to no network overhead (both the database and application servers are locally installed)
    • Vendor's default install of the current version of their software (with all current service or fix packs)
    • No other applications sharing the defined hardware configuration (for example, a clean machine)

    Any other hardware/software configurations are acceptable as long as they provide the same (or better) performance characteristics identified.
