Oracle Quota Error Tips

Expert Oracle Database Tips by Donald BurlesonMarch 29, 2015


Question:  I have an Oracle 11g instance, but I am running into an unexpected quota error.

 I have created a user.  I have granted create session and create table to the user.  The user can create tables anywhere except on tablespace system.

How is this possible?

Answer:  I will hazard a guess that you are on 11g R2 and are probably bumping into a known issue with deferred segment creation.

Oracle users have noted the following regarding quota issues:

Quota errors have resulted when an insert is issued against a table created against a tablespace with deferred segment creation enabled.  The table is reported as created, but with deferred segment creation, there are no resulting segment creations at the time of table creation.  This allows tables to be defined against any tablespace regardless of quotas. Therefore, the quota does not become an issue until the insert is attempted.

In 11g R2, the default for deferred segment creation is TRUE. 

Try setting deferred segment creation to FALSE prior to creating the tablespace using the following:

set deferred_segment_creation = FALSE

Then try your process again.
