Prerequisites for eMessage Reports

If you are using eMessage reports, you comply with specific prerequisites in addition to the system requirements for installing reports.

See Pré-requisitos for information about the system requirements for installing reports.

For better performance, you might need 40% of the data size as temp table space. Work with your database administrator to regularly fine-tune your database. For best results, you can store eMessage system tables in a separate tablespace that is mounted on a separate, unshared disk.
