Verify the Database Requirements

Verify the Database Requirements

Verify that your database meets the requirements for running
Data Integration Hub
.
The following table describes the database requirements for
Data Integration Hub
:
Database Component
Description
Database System
Type of database on which to install the repositories. You can use one of the following database systems:
  • Amazon RDS for Oracle
  • Oracle
  • Microsoft SQL Server
  • Microsoft Azure SQL Server
Database Instances
Two database instances.
Data Integration Hub
 uses one database for the
Data Integration Hub
 repository and one database for the publication repository. Both database instances must be on the same type of database system.
If you use Oracle databases, it is recommended that each database has a unique user account and a unique schema.
If you use Microsoft Azure SQL Server, it is recommended that you create a separate Data Source Name (DSN) for each database.
If you install the Dashboard and Reports component, an additional database instance is required for the operational data store. The operational data store must be on the same type of database system as the
Data Integration Hub
 repositories.
If you install the Dashboard and Reports component, your
Data Integration Hub
 and operational data store repositories are installed on Microsoft SQL Servers, and you use PowerCenter version 10, you must configure the repository connections in PowerCenter Workflow Manager. For details, see Configuring Repository Connections on PowerCenter Version 10.
Disk space
The
Data Integration Hub
 repository database requires at least
512 MB of disk space for the core application.
You also need additional space
on the publication repository database
based on the number of
publications and publication instances that you need to retain
.
Unicode data requires twice as much storage than single-byte character sets.
Database connections
Multiple
 database connections
for each repository
must always be available.
The number of required connections
for each repository
depends on the number of
publications and subscriptions that run
 concurrently. Use the following formula to calculate the number of required database connections
for each repository
:
NumberOf
ConcurrentPublicationsOrSubscriptions
 X 3 + 2
If you do not have enough database connections available,
Data Integration Hub
 might fail or encounter database deadlocks.

Database Unicode Support

If you require Unicode support, create the
Data Integration Hub
 repository database
and the
Data Integration Hub
 publication database
with the following settings:
  • Oracle databases: use the AL32UTF8 Unicode character set.
  • Microsoft SQL Server: it is recommended that you use data types that support Unicode data: nchar, nvarachar, and ntext.

Microsoft SQL Server Collation

If you use Microsoft SQL Server
or Microsoft Azure SQL Server
, the collation for the
Data Integration Hub
 repository
and for the
Data Integration Hub
 publication repository
must not be case sensitive.
