Use the following guidelines when you set up the repository on Oracle:
Verify that the database user has the following privileges:
ALTER TABLE
CREATE CLUSTER
CREATE INDEX
CREATE OR REPLACE FORCE VIEW
CREATE OR REPLACE PROCEDURE
CREATE OR REPLACE VIEW
CREATE SESSION
CREATE TABLE
DROP TABLE
INSERT INTO TABLE
Set the following parameters for the tablespace on Oracle:
<Temporary tablespace>
Resize to at least 2 GB.
CURSOR_SHARING
Set to FORCE.
MEMORY_TARGET
Set to at least 4 GB.
Run
SELECT * FROM v$memory_target_advice ORDER BY memory_size;
to determine the optimal MEMORY_SIZE.
MEMORY_MAX_TARGET
Set to greater than the MEMORY_TARGET size.
If MEMORY_MAX_TARGET is not specified, MEMORY_MAX_TARGET defaults to the MEMORY_TARGET setting.
OPEN_CURSORS
Set to 3000 shared.
Monitor and tune open cursors. Query
v$sesstat
to determine the number of currently-opened cursors. If the sessions are running close to the limit, increase the value of OPEN_CURSORS.
UNDO_MANAGEMENT
Set to AUTO.
If the repository must store metadata in a multibyte language, set the NLS_LENGTH_SEMANTICS parameter to CHAR on the database instance. Default is BYTE.
Informatica does not support Oracle public synonyms for repository tables. Verify that public synonyms have not been created for any tables in the database.
