The data object cache database stores cached logical data objects and virtual tables for the Data Integration Service. You specify the data object cache database connection when you create the Data Integration Service.
The data object cache database supports the following database types:
IBM DB2 UDB
Microsoft SQL Server
Microsoft Azure SQL Database
Oracle
Allow 200 MB of disk space for the database.
Ensure that you install the database client on the machine on which you want to run the Data Integration Service.
