Using Two Temporary Tablespaces in PeopleSoft

A longer version of this posting, with all necessary code and a demonstration test, is available as a technical note on the Go-Faster website.  I am working with two different PeopleSoft customers who have had challenges with the size of the temporary tablespaces.  Critical batch processes have failed because they have exhausted space in the temporary tablespace.

Temporary tablespaces in RAC

Temporary tablespaces are shared objects and they are associated to an user or whole database (using default temporary tablespace). So, in RAC, temporary tablespaces are shared between the instances. Many temporary tablespaces can be created in a database, but all of those temporary tablespaces are shared between the instances. Hence, temporary tablespaces must be allocated in shared storage or ASM. We will explore the space allocation in temporary tablespace in RAC, in this blog entry.

In contrast, UNDO tablespaces are owned by an instance and all transactions from that instance is exclusively allocated in that UNDO tablespace. Remember that other instances can read blocks from remote undo tablespace, and so, undo tablespaces also must be allocated from shared storage or ASM.
