Hmmm, that's hair-splitting, but if you reimport into a tablespace from
which all objects have been dropped and that you have coalesced, you
will have the same number of extents but they will all be created one
after the other - as many 'logical' extents as before, but as far as the
'macroscopic' (i.e. let's forget about how the OS deals with its blocks
and what happens on the disk) physical level is concerned there will
hardly be any difference with compress=Y immediately after creation.

That said, nobody cares much about external fragmentation anyway ...

With compress=N, you will get essentially the same mish-mash of extents you
had previously - unless you are importing into a LMT.

You have basically two options:

1) Pre-create the objects with a storage clause specifying the extent sizes
you want - with initial and next the same size.  Then import with ignore=Y.
Of course, if you drop the users, you will have to recreate them before
pre-creating the objects.  This is the only option for dictionary-managed
tablespaces to get uniform extents.  (Hint: imp ...
indexfile=somefilename.sql ..., edit somefilename.sql to (1) uncomment the
create table statements and (2) modify storage clauses, then run
somefilename.sql.  If the export is large, you may wish to split this into
two parts - one for the tables and one for the indexes and constraints.  (It
is a little more complicated than it might seem at first, but isn't too bad.
One possible approach is to perform one export with rows=Y indexes=N
constraints=N and another with rows=N indexes=Y constraints=Y.  Details left
as an exercise for the reader ;-)

2) Convert the tablespace(s) to LMT(s) with uniform extents - or drop and
recreate them as such - prior to the import.

In the vast majority of cases, (2) is preferred.

Hello,

Running Oracle 7.3.4.4 on Win2k.
Trying to implement unlimited extents of the same size. (Same size works
for us).
Set the tablespace defaults
Dumped the users
Dropped the users
Imported the users

Tables still had the same mish-mash of extents and max extents 121

Here are my dump params
USERID = system/@**
FILE = c:\dumps\test.dmp
LOG = c:\dumps\test.log
FULL = Y
buffer=100
consistent=y
compress=n

That did not work so I tried dumping an individual user
USERID = system/*@***
FILE = c:\dumps\test.dmp
LOG = c:\dumps\test.log
FULL = N
COMPRESS = N
owner=restek

Still get mish-mash extents on import.

The load was always:
USERID = system/**@*
FILE = c:\dumps\test.dmp
LOG = c:\dumps\test.dmprs.implog
FROMUSER = restek
TOUSER = restek

My quick test of create table tmp_xyz as select * from xyz gives me the
result I want.

Any suggestions?  Do I have to wait until I upgrade to 8i or 9i?

TIA

Thanks everyone for your advice.
If I want to retrofit to 7.3.4 I have to create the tables sans storage
clause then import import the data .

Otherwise wait until the database upgrade.

RE: exp73 dumpparam for unlimited extents?

2002-06-30 Thread Deshpande, Kirti

No, you do not have to wait for 8i or 9i
You are almost there to get what you want.
What you need to do prior to import is build all the tables without any
storage cluase in the CREATE TABLLE|INDEX syntax. It will default to the
tablespace settings. And them import with IGNORE=Y option (since tables are
already there). By default, Oracle will use the storage clause from the
import file. You can not tell Oracle to not have it created while exporting.
Pre-building the tables is the only choice. 

In your quick test, you did not specify the storage clause, so it worked!

You can use the indexfile=filename option of the import utility, to build
a script to create tables, indexes. Edit the script for storage clauses
(i.e. remove them), and build the tables first.

RE: exp73 dumpparam for unlimited extents?

2002-06-30 Thread Deshpande, Kirti

For the reported problem, (1) is the only option as (2) is not possible with
7.3.x database.

With compress=N, you will get essentially the same mish-mash of extents you
had previously - unless you are importing into a LMT.

You have basically two options:

1) Pre-create the objects with a storage clause specifying the extent sizes
you want - with initial and next the same size.  Then import with ignore=Y.
Of course, if you drop the users, you will have to recreate them before
pre-creating the objects.  This is the only option for dictionary-managed
tablespaces to get uniform extents.  (Hint: imp ...
indexfile=somefilename.sql ..., edit somefilename.sql to (1) uncomment the
create table statements and (2) modify storage clauses, then run
somefilename.sql.  If the export is large, you may wish to split this into
two parts - one for the tables and one for the indexes and constraints.  (It
is a little more complicated than it might seem at first, but isn't too bad.
One possible approach is to perform one export with rows=Y indexes=N
constraints=N and another with rows=N indexes=Y constraints=Y.  Details left
as an exercise for the reader ;-)

2) Convert the tablespace(s) to LMT(s) with uniform extents - or drop and
recreate them as such - prior to the import.

In the vast majority of cases, (2) is preferred.

Hello,

Running Oracle 7.3.4.4 on Win2k.
Trying to implement unlimited extents of the same size. (Same size works
for us).
Set the tablespace defaults
Dumped the users
Dropped the users
Imported the users

Tables still had the same mish-mash of extents and max extents 121

Here are my dump params
USERID = system/@**
FILE = c:\dumps\test.dmp
LOG = c:\dumps\test.log
FULL = Y
buffer=100
consistent=y
compress=n

That did not work so I tried dumping an individual user
USERID = system/*@***
FILE = c:\dumps\test.dmp
LOG = c:\dumps\test.log
FULL = N
COMPRESS = N
owner=restek

Still get mish-mash extents on import.

The load was always:
USERID = system/**@*
FILE = c:\dumps\test.dmp
LOG = c:\dumps\test.dmprs.implog
FROMUSER = restek
TOUSER = restek

My quick test of create table tmp_xyz as select * from xyz gives me the
result I want.

Any suggestions?  Do I have to wait until I upgrade to 8i or 9i?

TIA

And how will it  be of help in this export/import issue ? 
Sorry, I did not follow what you mentioned.

Deshpande, Kirti£¬
   hi, check oracle undocumented parameter: _system_trigger_enabled=false.
If this is set, then all database event trigger will be disabled.
Good luck


Good luck!

You are almost there to get what you want.
What you need to do prior to import is build all the tables without any
storage cluase in the CREATE TABLLE|INDEX syntax. It will default to the
tablespace settings. And them import with IGNORE=Y option (since tables are
already there). By default, Oracle will use the storage clause from the
import file. You can not tell Oracle to not have it created while
exporting.
Pre-building the tables is the only choice. 

In your quick test, you did not specify the storage clause, so it worked!

You can use the indexfile=filename option of the import utility, to build
a script to create tables, indexes. Edit the script for storage clauses
(i.e. remove them), and build the tables first. 


HTH,
