Use the following guidelines when you set up the repository on Oracle:
Set the storage size for the tablespace to a small number to prevent the repository from using an excessive amount of space. Also verify that the default tablespace for the user that owns the repository tables is set to a small size.
The following example shows how to set the recommended storage parameter for a tablespace named REPOSITORY:
ALTER TABLESPACE "REPOSITORY" DEFAULT STORAGE ( INITIAL 10K NEXT 10K MAXEXTENTS UNLIMITED PCTINCREASE 50 );
Verify or change the storage parameter for a tablespace before you create the repository.
Verify that the database user has the following privileges:
CREATE SEQUENCE
CREATE SESSION
CREATE SYNONYM
CREATE TABLE
CREATE 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.
You can configure the connection between the Informatica domain, Model Repository Service, or PowerCenter Repository Service and Oracle RAC. Oracle Real Application Clusters (RAC) enables high availability of database applications. The Informatica domain, Model Repository Service, and PowerCenter Repository Service are resilient to failover of Oracle RAC databases for all CRUD operations.
The following operations in the PowerCenter Repository Service are resilient to the database failover in Oracle RAC setup:
