I have two oracle environment with similar configuration.

Creating index organized table is working in one environment but not in another environment.

I know that including OVERFLOW clause will solve this. But I want to know exact root cause why same IOT command working in one db and not in another db. These Dbs are similar and their tablespace blocksize too same.

Let me know where I need to check.

Thanks

post results from query below from both databases.

SELECT owner, object_type from all_objects where object_name = 'OIDINDEX';

What is the setting for the deferred_segment_creation parameter in each database, and what is the schema's default tablespace?

select * from v$version;
for both databases.

Before, Please How to use [code] tags and make your code easier to read.

I know this is some environment setup issue. But I need to identify the exact root cause. The same create table command works fine in one DB and not in another DB.

Tell me where I need to check.


--update: I've corrected your code tags. Please read the guidelines again, and this time do it properly.

Perhaps your databases have a different block size. There is a limit on the length of an index key in proportion to a block which you could be hitting:
orclz> CREATE TABLE SAMPLE_INDEX
  2  (
  3  ID NUMBER NOT NULL PRIMARY KEY,
  4  INDEX_NAME VARCHAR2(30) NOT NULL,
  5  TABLE_NAME VARCHAR2(30) NOT NULL,
  6  COLUMN_EXPRESSION VARCHAR2(4000)
  7  )
  8  ORGANIZATION INDEX ;
CREATE TABLE SAMPLE_INDEX
*
ERROR at line 1:
ORA-01429: Index-Organized Table: no data segment to store overflow row-pieces


orclz> CREATE TABLE SAMPLE_INDEX
  2  (
  3  ID NUMBER NOT NULL PRIMARY KEY,
  4  INDEX_NAME VARCHAR2(30) NOT NULL,
  5  TABLE_NAME VARCHAR2(30) NOT NULL,
  6  COLUMN_EXPRESSION VARCHAR2(1000)
  7  )
  8  ORGANIZATION INDEX ;

Table created.

Finally narrow down the root cause.

difference is in 'nls_length_semantics' parameter.

In working db, it is set to 'BYTE' but in problematic db, it is set to 'CHAR'.

Changed this parameter to 'BYTE' in problematic DB and now I can able to create the same table.

Many thanks for all your support.

In this case, the root is still the field length, as 1024 CHAR means 2048 or 4000 bytes depending on your character set.

Generally speaking, NLS_SEMANTICS_LENGTH should always been set to CHAR. I never saw requirements talking about string space size but always about number of characters of strings.
