Workflow Database Requirements

The Data Integration Service stores run-time metadata for workflows in the workflow database. Before you create the workflow database, set up a database and database user account for the workflow database.

You specify the workflow database connection when you create the Data Integration Service.

The workflow 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.

Note: Ensure that you install the database client on the machine on which you want to run the Data Integration Service.

IBM DB2 Database Requirements

Use the following guidelines when you set up the repository on IBM DB2:

•Verify that the database user account has CREATETAB and CONNECT privileges.
•Informatica does not support IBM DB2 table aliases for repository tables. Verify that table aliases have not been created for any tables in the database.
•Set the tablespace pageSize parameter to 32768 bytes.
•Set the NPAGES parameter to at least 5000. The NPAGES parameter determines the number of pages in the tablespace.
•Set the connection pooling parameters.

The following table lists the connection pooling parameters that you must set:

Parameter	Value
Maximum Connection Pool Size	128
Minimum Connection Pool Size	0
Maximum Idle Time	120 seconds

Microsoft SQL Server Database Requirements

Use the following guidelines when you set up the repository:

•Verify that the database user account has CONNECT and CREATE TABLE privileges.
•Set the connection pooling parameters.

The following table lists the connection pooling parameters that you must set:

Parameter	Value
Maximum Connection Pool Size	128
Minimum Connection Pool Size	0
Maximum Idle Time	120 seconds

Oracle Database Requirements

Use the following guidelines when you set up the repository on Oracle:

• Verify that the database user has the following privileges:

- ALTER TABLE
- ALTER VIEW
- CREATE SEQUENCE
- CREATE SESSION
- CREATE SYNONYM
- CREATE TABLE
- CREATE VIEW
- DROP TABLE
- DROP VIEW

•Informatica does not support Oracle public synonyms for repository tables. Verify that public synonyms have not been created for any tables in the database.
•Set the connection pooling parameters.

The following table lists the connection pooling parameters that you must set:

Parameter	Value
Maximum Connection Pool Size	128
Minimum Connection Pool Size	0
Maximum Idle Time	120 seconds
