Introduction
This installation guide describes how to install the SAP HANA Data Warehousing Foundation - Data Distribution
Optimizer (Data Distribution Optimizer).
The Data Distribution Optimizer is delivered with delivery units (DU). A DU is used to deliver one or more software
components from SAP (or a partner) to a customer. A DU is contained in a delivery unit archive (*.tgz file) for
distribution using export/import and deployment. For more information on delivery units, see the SAP HANA
Master Guide.

About the Data Distribution Optimizer
The Data Distribution Optimizer is part of SAP HANA Data Warehousing Foundation, which provides packaged
tools for large scale SAP HANA use cases to support data management and distribution within a SAP HANA
landscape more efficiently. With the Data Distribution Optimizer, SAP HANA Data Warehousing Foundation
provides an SAP HANA XS Engine based tool to plan, adjust and analyze landscape redistribution.
The main purpose of the Data Distribution Optimizer is to help the SAP HANA administrator to manage the
distribution of tables and optimize the allocation of SAP HANA memory in a SAP HANA scale-out landscape
(multiple-host system). The redistribution algorithm has to reflect the relationship between single tables as well
as constraints given by the landscape itself, such as allocation limits and server roles (e.g. master or slave).
The end-to-end process for distributing data consists of the following main steps:
1. Getting a system landscape overview
2. Configuring the redistribution of table partitions
3. Comparing redistribution plans with current distribution and executing the redistribution when the
requirements are met

1.2
Overview of Data Distribution Optimizer Architecture
Data Distribution Optimizer is composed of the components shown in the graphic below.
The Data Distribution Optimizer user interfaces are based on SAPUI5 technology and run in a Web browser.
The SAP HANA Data Warehousing Foundation Core component (HCO_HDM) provides base services, such as
scheduling, that can be used by any of the SAP HANA Data Warehousing Foundation tools.
The SAP HANA Data Warehousing Foundation Data Distribution Optimizer component (HCO_HDM_DDO)
contains Data Distribution Optimizer specific logic, such as the logic for generating redistribution plans.
The SAP HANA Core Distribtuion Services contain modules that SAP HANA Data Warehousing Foundation calls in
the SAP HANA core, such as database procedures REORG_GENERATE and REORG_EXECUTE.
1.3
Supported Browsers
Data Distribtion Optimizer is based on SAPUI5 1.22.4.
For an overview of the supported browsers, see the Product Availability Matrix for SAP HANA Data Warehousing

User Authorization
Every user who is required to work with Data Distribution Optimizer (DDO) must have a database user. To
perform tasks in the Data Distribution Optimizer, the database user must have the required privileges. Data
Distribution Optimizer is delivered with a set of roles containing the required privileges for specific tasks.
The following table describes the roles for Data Distribution Optimizer:
Table 3:
Role
Type
Task
sap.hdm.ddo.roles::Viewer
application
This role provides read-only access to view redistribution
plans. It also allows you to view configurations. The role
does not allow you to view all data for all tables in the Data
Distribution Optimizer however, as this would require ex
pansive authorizations that are not appropriate for a
viewer role. The following information is not visible for the
viewer role for example:
●
Information on the last run will not be visible on the
Home screen.
●
The system landscape information will not be dis
played on the System Landscape screen.
●
Most of the system catalog will not be displayed on the
System Landscape screen (only the SAP_HDM_DDO
schema).
sap.hdm.ddo.roles::Configurator
application
This role has to be granted to the database user who cre
ates Data Distribution Optimizer configurations. It also al
lows importing and exporting of plans.
sap.hdm.ddo.roles::Scheduler
application
This role has to be granted to the database user who
schedules redistribution plan execution.

Create and Authorize Users
Every user required to work with Data Distribution Optimizer (DDO) must have a database user. To perform data
distribution tasks, specific roles must be granted to the database user(s) by a user administrator.
Prerequisites
● You have the system privilege USER ADMIN.
● You have the privileges required to grant specific privileges and roles to the new user. For more information,
see Prerequisites for Granting and Revoking Privileges and Roles in the SAP HANA Administration Guide.

the supported mechanisms, the necessary infrastructure must be in place and configured.
Procedure
1. If the database user that you want to authorize does not exist yet, create the user:
Note
For generating redistribution plans (role sap.hdm.ddo.roles::Planner) and for executing redistribution
plans (role sap.hdm.ddo.roles::Executor), we recommend creating technical users.
1. In the Systems view, choose
