Steve,

Come over here and let me speak with you in private....

Do you really want to advise people to start editing the sql.bsq file if they don't know whether or not they can change data dictionary defaults?

Don't you think that if they are asking the question then the answer for them (at that level of experience) is a hale and hearty NO?

What's next, indexes on the data dictionary? Analyzing the sys schema? DOGS AND CATS LIVING TOGETHER? To quote from "Bridge Over the River Quai": "Madness! Madness!"

Once they reach the level of experience where they know what doing things like changing the DD defaults means, then they will also know whether or not it is a good idea and why.

Until they know, just say no!

Just call it the zen philosophy of being an Oracle DBA.

ricochet...

Ah, but it is "broken" or will become broken if you use it much. "Broken" being defined as poor space management and performance hindering fragmentation.

Do experienced DBA's accept the all the Oracle defaults for DB creation? Of course not so why accept the defaults within the data dictionary? Have courage, be a man, or goddess, and copy the sql.bsq to $ORACLE_BASE/admin/<SID>/create and edit it to set the proper storage clauses.

Set the following in your init<SID>.ora file (for db_creation only):

_init_sql_file = /PathToOracleBase/admin/<SID>/create/sql.bsq

Then choose a healthy db_block_size and create your database. Then set the system tablespace defaults to something like the following:

ALTER TABLESPACE SYSTEM
 DEFAULT STORAGE ( INITIAL 64K MINEXTENTS 1 MAXEXTENTS 4096

                   PCTINCREASE 100) ;

ALTER TABLESPACE SYSTEM MINIMUM EXTENT 64K ; Then create the rest of your tablespaces and rollback segments and install any Oracle supplied packages. OK, you may want to think about that PCTINCREASE 100 setting. But don't get crazy and make system a locally managed tablespace. Wait for Oracle on this one.

Need more encouragement? See Steve Adam's "Customizing SQL.BSQ" web page: http://www.ixora.com.au/tips/creation/bsq.htm

Be thou of good courage. Shrink not from thine appointed destiny. Seek and ye shall find, ask and it shall be given thee, knock and it shall be opened to thee. Take heart, the Oracle is with thee.
