If you ve already created the undo tablespace, you can make it auto-extensible by simply adding an auto-extensible data file to the undo tablespace, as shown here: SQL> ALTER TABLESPACE undotbs_01 ADD DATAFILE '/u01/oradata/prod/undo0102.dbf' AUTOEXTEND ON NEXT 5M MAXSIZE UNLIMITED; If, for some reason, you decide that you have to create a fixed-size undo tablespace, you can use the Undo Advisor to get recommendations about the ideal size. The Undo Advisor uses the data collected by the Automatic Workload Repository (AWR) as the basis for its analysis, so you should let the instance run for a good while after you start it, so that the Undo Advisor has enough data to figure out its recommendations. The Undo Advisor takes two inputs the estimated length of the longest query in the database, and how far you want to go back in time for your Flashback operations that depend on undo data. Using the larger of these as a guide, you can look up the ideal size for your undo tablespace on an Undo Advisor graph. I explain how to use the Undo Advisor later in this chapter, in the Using the OEM to Manage Undo Data section.

Sometimes when you start an instance or switch an undo tablespace, it takes several minutes for the undo segments to come online. To avoid this problem, the database uses the data in the Automatic Workload Repository to determine the number of undo segments to bring online upon an instance restart or the switching of an undo tablespace. This feature is also known as the fast ramping up of undo segments.

When a transaction commits, the undo data for that transaction isn t needed any more. That undo data will stay in the undo tablespace, however, until space is needed to record undo data for newer transactions. When the newer transactions undo data comes in, it may overwrite the old undo data (from the committed transactions) if there isn t enough free space left in the undo tablespace. For a long-running query that needs to retain older undo data for consistency purposes, there is a possibility that some of the undo data it needs has been overwritten by other, newer transactions. In this case, you could get an error message ( snapshot too old ) from the database indicating that the before-image of the transaction has been overwritten. To prevent this, Oracle provides the UNDO_RETENTION configuration parameter, which you can set to the interval you wish. Note that in the older manual undo management mode, DBAs don t have the option of determining how long Oracle retains undo information. Let s briefly review how undo information is managed in an undo segment. Undo information can be classified in two broad types: If a transaction that has generated the undo data is still active, the undo data is said to be active (uncommitted). Oracle will always retain active undo data to support ongoing uncommitted transactions. If the transaction that generated the undo data is inactive (committed), then the undo data is said to be committed. The committed undo data can be either expired or unexpired. Expired data can be overwritten by new transactions. Oracle will try to save the unexpired data as long as it can, subject to undo space limitations. When there is no more room in the undo tablespace for newer transactions, Oracle will finally overwrite the unexpired data, depending on how you configure the UNDO_RETENTION parameter. The UNDO_RETENTION parameter lets you control the reuse of the committed undo space. By setting the UNDO_RETENTION parameter, you can specify the lower limit for how long the database will retain uncommitted undo data as unexpired data, so that it is available for read consistency and Flashback purposes. Note that setting the UNDO_RETENTION interval is not a guarantee that Oracle will always retain undo information for at least that time period. If there is no free space left in the undo tablespace for
