Review the Prerequisites

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 Mart Portal application:

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

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

System requirements for installing the Mart Portal application

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

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

4 GHz or higher quad-core processor
16 GB RAM
100 GB of disk space or more as required to support your specific mart

Operating system:

Microsoft Windows Server 2016
Microsoft Windows Server 2019
Microsoft Windows Server 2022

Microsoft .NET Framework 4.0 and above
All current Microsoft Windows critical updates are applied

Database:

The Mart Portal can use a standalone or can share an existing database server for an Oracle 12c R2, 18c, 19c, or 21c database. You can also 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 Mart Portal 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 Portal web client:

Supported browsers:

Microsoft Edge v97 or newer
Mozilla Firefox v91 or newer
Google Chrome v97 or newer
Apple Safari 15 or newer

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.
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

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.
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.
