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.
