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.


If you have created your own procedure(s)/function(s), use sequences or reference views in your scripts, you should ensure that you grant the Subset user the appropriate permissions.

Microsoft Sql Server

Permissions


The user subsetting the database should have dbo permissions in the database targeted for Subsetting.

The Source database should allow for "Ad hoc distributied queries". 

If you have Views with Schemabinding ON it is not possible to run the Recreate scenario,

Powershell module dependency

To retrieve DDL information from Microsoft Sql Server, 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 delivered with Subset and does not need to be installed manually.

Microsoft Powershell version 5 is required.

Linux systems

When using Runtime on a Linux system, Powershell must be installed and also the "SqlServer" module needs to be installed manually.

For installing powershell on a Linux system see the Microsoft documentation: https://docs.microsoft.com/nl-nl/powershell/scripting/install/installing-powershell-core-on-linux.

To install the required Sqlserver module execute this:

  • Open a Powershell window on your system, either as the user running Runtime or as root
  • Install the module with the command: Install-Module -Name SqlServer
