Hi,

I'm runing on Oracle 8i Release 8.1.7.2.0.

In my Initialization parameters file I have for the "COMPATIBLE" parameter the value: 8.1.5.0.0.

I received this ORA-00406 error message when trying to:

ALTER TABLE table_name STORAGE (FREELISTS 5);

I have 5 processes performaing heavy insert in 2 of my tables and this can help me maybe to increase the performance on these tables (as space on disk is not an issue here).

Do I have just to update this COMPATIBLE init parameter? Is it just ok to update the value from 8.1.5.0.0 to 8.1.6.0.0? Or it would bring or generate�some drawbacks or other problems?

My tables are on tablespaces of type Locally Managed Tablespace: I thought that with such LMT tablespaces, the storage parameters in the STORAGE clause couldn't be altered or decided at creation time?

Thank you for your help!

Regards,

Patrick Tahiri.

Hi,

It would be best to set COMPATIBLE to 8.1.7.0.0 and get it done with. The Migrations Guide documents what additional features are enabled at each compatibility level.

Steps:

1. Add the "COMPATIBLE=8.1.7.0.0" parameter to your INIT.ORA file.

2. SQL> SHUTDOWN IMMEDIATE

3. SQL> STARTUP

For additional info, read chapter 9 "Compatibility and Interoperability" of the Oracle8i Migration Guide.

Best regards.

Frank

Thank you for your answer!

Just something else: Can we define the STORAGE clause and especially FREELISTS on objects within a tablespace that is Locally Managed Tablespace?

ALTER TABLE table_name STORAGE (FREELISTS 5);

and this table is on a locally managed tablespace. Is it possible with LMT?

Many thanks again.

Regards,

Patrick Tahiri.

Yes, you can. Look at this example:

SQL> create tablespace x datafile '/tmp/x.dbf' size 5M extent management local;

Tablespace created.

SQL> create table tab_x (a date) tablespace x;

Table created.

SQL> alter table tab_x storage (freelists 5);

Table altered.

SQL> drop tablespace x including contents and datafiles;

Tablespace dropped.

BTW: You might want to use "SEGMENT SPACE MANAGEMENT AUTO" instead of FREELISTS.

Best regards.
