Reference Data Warehouse Requirements
The reference data warehouse stores the data values for reference table objects that you define in a Model repository. You configure a Content Management Service to identify the reference data warehouse and the Model repository.
You associate a reference data warehouse with a single Model repository. You can select a common reference data warehouse on multiple Content Management Services if the Content Management Services identify a common Model repository. The reference data warehouse must support mixed-case column names.
The reference data warehouse supports the following database types:
- •IBM DB2 UDB
- •Microsoft SQL Server
- •Microsoft Azure SQL Database
- •Oracle
- •PostgreSQL, using a JDBC driver
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 Content Management 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.
- •Verify that the database user has SELECT privileges on the SYSCAT.DBAUTH and SYSCAT.DBTABAUTH tables.
- •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.
Microsoft Azure SQL Database Requirements
Use the following guidelines when you set up the repository:
- •Set the allow snapshot isolation and read committed isolation level to ALLOW_SNAPSHOT_ISOLATION and READ_COMMITTED_SNAPSHOT to minimize locking contention.
To set the isolation level for the database, run the following commands:
ALTER DATABASE DatabaseName SET ALLOW_SNAPSHOT_ISOLATION ON
ALTER DATABASE DatabaseName SET READ_COMMITTED_SNAPSHOT ON
To verify that the isolation level for the database is correct, run the following commands:
SELECT snapshot_isolation_state FROM sys.databases WHERE name=[DatabaseName]
SELECT is_read_committed_snapshot_on FROM sys.databases WHERE name = DatabaseName
- •The database user account must have the CONNECT, CREATE TABLE, and CREATE VIEW privileges.
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.
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 SEQUENCE
- - ALTER TABLE
- - CREATE SEQUENCE
- - CREATE SESSION
- - CREATE TABLE
- - CREATE VIEW
- - DROP SEQUENCE
- - DROP TABLE
- •Informatica does not support Oracle public synonyms for repository tables. Verify that public synonyms have not been created for any tables in the database.
PostgreSQL Database Requirements
Use the following guidelines when you set up the repository on PostgreSQL:
- •Use a JDBC connection to connect to the PostgreSQL database.
- •Specify the database schema name. Do not leave the schema name blank.
If the database uses the default PostgreSQL schema name of public, you can specify public as the schema name.
- •Verify that the database user has the CONNECT and CREATE TABLE privileges.
