Requirements

Operating System

DATPROF Subset requires one of the following:

• Microsoft Windows 7 or later

• Microsoft Windows Server 2012 or later

Additionally, the .NET Framework 4.8 must be installed, and the user installing the software must have the necessary permissions to install applications.

Hardware

• CPU: x86 1 GHz or better

• Memory: At least 4 GB RAM

• Disk Space: At least 1 GB of free disk space

Supported Databases

DATPROF follows the software lifecycle guidelines set by database vendors. This ensures compatibility and support with the latest versions of database systems while maintaining the stability and reliability of the tool. By aligning with the database vendors' lifecycle, DATPROF ensures that its solutions stay up-to-date with new features, security patches, and performance enhancements.

Database Requirements and Permissions

Oracle RDBMS

Permissions

Source Schema

Select permissions to read the data

Target Schema

If the Subset User is the TABLE_OWNER

Minimum System Privileges

• CREATE SESSION

• CREATE TABLE

• CREATE INDEX

• CREATE databaselink (or have one pre-created from the Target Schema to the Source Schema by your DBA)

Minimum Object privileges

• EXECUTE permission on dbms_random package

• EXECUTE permission on dbms_metadata package

Quota

• Unlimited tablespace

Multiple schemas

These privileges should be extended when using tables in multiple schemas.

In such a scenario, the Subset user also requires:

• to have been GRANTED the SELECT_CATALOG_ROLE

• CREATE ANY TABLE

• CREATE ANY INDEX

• DROP ANY INDEX

• DROP ANY TABLE

Subset uses the ALL_TAB_PRIVS view to get the list of objects across all selected schemas.

Sometimes it is necessary to grant select on one table in a schema to make the schema appear in Subset using the ALL_TAB_PRIVS.

When you create your own procedures, functions, use sequences, or reference views in your scripts, it is essential to ensure that the Subset user is granted the necessary permissions to access and execute these elements.

Microsoft SQL Server

Permissions

To perform database subsetting, the user must have dbo permissions in the target database.

The source database must also permit Ad hoc distributed queries.

Additionally, if you have views with Schemabinding enabled, it will not be possible to execute the Recreate scenario.

Powershell module dependency

To retrieve DDL information from Microsoft SQL Server, DATPROF Runtime uses a PowerShell module. Over time, Microsoft has replaced the original "SQLPS" module with the "SqlServer" module.

As of version 4.0, the SqlServer module is included with DATPROF Subset and no longer needs to be installed manually.

Microsoft PowerShell version 5 or later is required to use the SqlServer module.

1. Open a PowerShell window on your system as administrator.

2. To check your current PowerShell version, run the following command:

   CODE

   $psversiontable.Psversion

3. If the major version is lower than 5, you need to upgrade PowerShell. To do so, download and install Windows Management Framework version 5.x from the following link: Windows Management Framework 5.1

Linux systems

When using Runtime on a Linux system, PowerShell must be installed, and the SQL Server PowerShell module needs to be manually installed.

To install PowerShell on a Linux system, refer to the Microsoft documentation: Install PowerShell on Linux.

Once PowerShell is installed, follow these steps to install the SQL Server module:

1. Open a PowerShell window on your system (either as the user running Runtime or as root).

2. Execute the following command to install the required module:

   CODE

   Install-Module -Name SqlServer

This will install the necessary SQL Server module for PowerShell, enabling you to manage SQL Server from your Linux environment.

DB2 LUW

Requirements

To use DATPROF Subset for DB2 Linux, Unix, and Windows (LUW), the following IBM software is required on the client PC:

• IBM DB2 Data Server Driver Package

Once installed, DATPROF Subset will use the 32-bit DLLs located in the subfolders netf40 or netf40_32. These DLLs are necessary for establishing a connection and working with IBM DB2 databases.

Permissions

Source Database:
The user should have read (select) permissions for all tables that need to be subsetted in the source database.

Target Database:

• CONNECT: Permission to establish a connection to the database.

• DATAACCESS: Permission to access the data within the database.

• CREATETAB: Permission to create tables, which is required during the data masking process.

DB2 iSeries

Requirements

To use DATPROF Subset with DB2 iSeries, you should have one of the following installed:

• IBM i Access for Windows 7.1, or

• IBM i Access Client Solutions

This software can be obtained from the IBM website.

Permissions

The user responsible for masking the database must have DBADM (Database Administrator) permissions in the database schema targeted for data masking.

DB2 for z/OS (Mainframe)

Requirements

In order to use Subset with DB2 for z/OS databases, the user must possess their own db2jcc_license_cisuz.jar file - This is the IBM Data Server for JDBC and SQLJ license file that allows access to the database through the JDBC protocol. This is a separate license that must be acquired through IBM. This file must then be placed in the Drivers sub-folder of the Subset installation folder. If this is not done, the user is greeted by the following error upon trying to test a connection to the database:

Permissions

Source database

The user should have the permission to read (select) all tables to be subsetted in the source database.

Target database

The user should have DBADM permissions in the target database.

PostgreSQL

Requirements

You should install the Postgres foreign-data wrapper (postgres_fdw) in each database that you will use as a target database. The following statement must be executed as a super user in each target database: 

CREATE EXTENSION postgres_fdw;

Permissions

Source database

The user should have the permission to read (select) all tables to be subsetted in the source database.

Target database

The user should have 'Super User' right to perform all necessary steps
