Hi,
How about your SYSTEM tablespace?
If your system tablespace is created as locally managed, you can't create any dictionary managed tablespace.
Using the following SQL to see the details:
select * from dba_tablespaces where tablespace_name='SYSTEM';

regards

Hi,

I'm new to SQL as well.

How can I modify the SQL statements to conform to my system

I actually have 8 examples I need to follow. 4 to create tablespaces, a few others to create users, report role, and granting report role priviledges.


Thanks

... and the following sql statements yield

SQL> select tablespace_name from dba_tablespaces;

TABLESPACE_NAME
------------------------------
SYSTEM
UNDOTBS1
TEMP
CWMLITE
DRSYS
EXAMPLE
INDX
ODM
TOOLS
USERS
XDB

11 rows selected.

and another not so readable

SQL> select * from dba_tablespaces where tablespace_name='SYSTEM';

TABLESPACE_NAME BLOCK_SIZE INITIAL_EXTENT NEXT_EXTENT MIN_EXTENTS
------------------------------ ---------- -------------- ----------- -----------
MAX_EXTENTS PCT_INCREASE MIN_EXTLEN STATUS CONTENTS LOGGING FOR EXTENT_MAN
----------- ------------ ---------- --------- --------- --------- --- ----------
ALLOCATIO PLU SEGMEN
--------- --- ------
SYSTEM 8192 65536 1
2147483645 65536 ONLINE PERMANENT LOGGING NO LOCAL
SYSTEM NO MANUAL

Hi,

ORA-12913 Cannot create dictionary managed tablespace

Cause: An attempt was made to create a dictionary managed tablespace in a database whose SYSTEM tablespace is locally managed.

Action: Create a locally managed tablespace.

When creating tablespace you have to use extent management local.

greetings,

Michael

Hi,

Following are three different cases of the statements.

SQL> create tablespace visionael_tempspace
2 extent management local
3 datafile 'c:\oracle\oradata\orak\orak_tmp01.dbf' size 10 M
4 autoextend on next 10M
5 default storage (
6 initial 50K
7 next 50K
8 minextents 1
9 maxextents 121
10 pctincrease 10
11 ) temporary online;
create tablespace visionael_tempspace
*
ERROR at line 1:
ORA-12913: Cannot create dictionary managed tablespace


SQL> create tablespace visionael_tempspace
2 extent management local
3 datafile 'c:\oracle\oradata\orak\orak_tmp01.dbf' size 10 M;

Tablespace created.


SQL> create tablespace visionael2_tempspace
2 datafile 'c:\oracle\oradata\orak\orak2_tmp01.dbf' size 10 M
3 ;

Tablespace created.

So twice the tablespaces have been created without using the rest of the options

I do not mean to use your help and cooperation to entirely solve my problems, but how do I proceed now?

-I don't know what's causing the error
-I have created two tablespaces whoich I either have to delete or incorporate within them the other options

Hi,

I am not sure, what problem you still have.
The first statement failed, because the default is a dictionary managed extent management, which conflicts with a locally managed system tablespace. In example two and three you used local extent management. The rest of the options was replaced by their default values. You can go on with the instructions, the software manual gives you.

greetings,

Michael

SQL> select * from dba_tablespaces where tablespace_name='SYSTEM';

TABLESPACE_NAME BLOCK_SIZE INITIAL_EXTENT NEXT_EXTENT MIN_EXTENTS

As your reply above, you cannot create new DICTIONARY managed tablespaces, and you cannot migrate a LOCALLY managed SYSTEM tablespace back to DICTIONARY.
Syntax to create LOCALLY managed tablespace:
CREATE TABLESPACE userdata
DATAFILE '/u01/oradata/usr01.dbf' SIZE 500M
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K;

Hope this can help you.

[twang]

Why fail, for locally managed tablespaces, the LOCAL option of the EXTENT MANAGEMENT clause specifies that a tablespace is to be locally managed. By default a tablespace is locally managed.
extent_management_clause for Locally-managed tablespace:==
[ EXTENT MANAGENT
[ LOCAL
[ AUTOALLOCATE | UNIFORM [SIZE integer [K|M]]]]]

And UNIFORM specifies that the tablespace is managed with uniform extents of SIZE bytes. Default size is 1 megabyte.
Good luck.

Thanks a lot Michael, Twang, and all else who helped, persisted, and followed up. Exactly the reason why for ANY rpoblem I refer to ITRC

The products support team pointed me to an Oracle Repository Builder script, which eventually solved the problem.

I have though learnt a lot from your posts, and they might motivate me to learn more DBA stuff.

Thanks a lot

Hi Omar,

learning DBA Stuff is a good idea. It will not only make your own work more fun and more satisfactory, when you know, what other people/documents are talking about but also you may give other people just the right hint to solve their own problem. ;-))))

So, learn and share,

Michael
