FRAGMENTATION_STATUS of some tablespaces shows Bubble Frag. Can it create any problem to create procedure in database? how does it impact on overall performance of the databse? is it possible to convert dictionary managed tablespace to locally managed table space, and what is the command?
Regards,
Alina

You have to this as SYS user and database should be in restricted mode.
Sql> Startup restrict;
sql> exec your_procedure.
If SYS user is not doing this, you need to give execute priviliges on the USER executing this.
More information in documentation.

Please search Orafaq.com about what fragmentation is and what LMT can do for it. As long as you have the LMT with UNIFORM extent size, you can very minimise this. Technically sttill, you cannot completely avoid fragmentation in the block level( depends on your PCTFREE/PCTUSED) or row level ( a row migration/chaining cannot be avoided). For now, it is ***almost*** safe to say,
Use LMT with UNIFORM extent size and there is no fragmentation.
