Hi Avi

You are getting this error because deferred segment creation is only available in Enterprise Edition (see http://download.oracle.com/docs/cd/E11882_01/license.112/e10594/editions.htm#CJACGHEB).

But, to answer your question, it would be necessary to know how you get it. In fact, if you ask the question, I guess that you know this restriction and, therefore, it’s not because you specified the “segment creation deferred” option in a CREATE TABLE statement… So, let me know what you are doing.

Cheers,
Chris

I just wrote a new post that shows how to get rid of empty segments. Refer to Deferred Segment Creation as of 11.2.0.2.

[...] me un grande entusiasmo, comunque disattivabile tramite apposito parametro come ricordato anche da Antognini in un suo post di approfondimento [...]

Ciao Giuseppe

Ufff… really weird situation… I didn’t know that it was an EE edition feature.

To solve the problem I would try to create the tables before importing the data.
If you do not have the scripts to create the tables, you should be able to extract the DDL from the DP file with the SQLFILE option.

I had to downgrade from EE 11.2 to SE 11.2, I was unable to impdp the schemas from EE because of “feature not available” regarding the “deferred segment creation” which is default. Now I deleted EE Database and I can’t import schemas on the new (SE) one. I can’t figure how to complete my porting. Any suggestion??

Users of deprecated tools beware! exp (the conventional data export tool) does not export tables that have not yet had their segment allocated.

Hi Anthony

What is the purpose of doing so? Sorry, but I don’t understand… I mean, here the point is to *not* allocate extents…

Cheers,
Chris

Just use:

alter table allocate extent;

to allocate segment extents.
