Use exp/imp to migrate a database

hi,
I want to migrate a database from window to hp unix,
Can I use the following way? thanks!
First,exp from windows:
1.exp the schema without data
2.exp the whole database with data
Second,imp to unix:
1.use dbca to create a database;
2.imp the schema
3 imp the data to all schema.

Yes. Just make sure that you do a binary file transfer between windows and unix system otherwise you will end up with a corrupted dump.
Even after transfer, just to make sure, you can have a trial import with indexfile and show options to check the integrity of the dump.
Probably you can merge steps 2 and 3 of import in 1 step.

Using exp/imp to clone a database from Solaris to NT

Hi All,
We have an 8.1.6 Oracle database in production under Sun Solaris.
We actually use this database to run Siebel CRM system.
We have a Windows NT server which we used as a QA system
for this application.
We have a daily full export of our production database on the
Sun machine. Now my manager wants to import this production
dmp file into this Win NT database on a weekly basis.
The goal here is to maintain the state of this NT database
as much functional and close to the production one as possible.
I would appreciate your help on this.
I have some other general question:
in which case can the Oracle imp utility be run in the
full=y mode ?
does this make any sense at all ?
since the Oracle import utility does not delete
any existing objects before it imports, these objects
should be deleted manually and that's what I do
with all Siebel users schemas; of course I do not
do this with SYS, SYSTEM and other special Oracle
users; question: are there any objects in these
special Oracle schemas that have to be carried over from
the source database to the target database to
make the rest of the schemas functional ?
Somehow I failed to find Oracle documentation on how
to use exp/imp to create a complete clone of an Oracle
database.
Can direct path be used with full=y export/import mode ?
Thank you in advance,
Yuriy.

As an alternative to using daily/weekly exports and imports, what would probably be more effective here would be replication. The databases could synch on a nightly basis and updated tables and rows will be transferred from your OLTP system to your read-only system. More information can be found on replication from "Oracle8i DBA Handbook" by Kevin Loney and Marlene Therialt.

Hi Sa;
Does anyone have experience in using exp and imp utility on 11i apps database? Is there any special method to achieve this. You want to take exp imp for which issue?
I want to do a full export and do an import.Follow:

Refresh using exp/imp

Hi All,
I need to refresh one of my development database using exp/imp utility,i did refreshing using the copy datafiles but new to this ,i have gone thru this forum and did some search on google too but the part that am not getting is suppose my development db already created with same tablespaces name and size and containes every schema as that of source and has data in it which is refreshed earlier, so do i need to wipe out everything and do it right from scratch(create db,tablespace,users) or just wipe out tables and import with (ignore=Y) .Any feedback would be apperciated.
Thanks

Hi,
 
>> do i need to wipe out everything and do it right from
scratch(create db,tablespace,users)
 
Well you have choices, and you can do whatever you want,
but there are some “best practices”. I’m assuming that you are copying your
PROD database into DEV (a great practice to have a full-sized production system
the TEST and DEV):
 
- You can restore PROD into TEST using RMAN.
 
- You can use the

Oracle Universal Installer</a> to clone a database.
 
- You can “<a style="color: blue; text-decoration: underline; text-underline: single" href="oracle_tips_db_copy.htm">clone
the whole database</a>”, moving the current datafiles and recreating the
instance
 
- You can export from PROD, truncate the tables in DEV
(after a backup) and import IGNORE=Y. This can be very slow, especially for a
large database. However, there are some

Best way of using exp/imp

Dear all,
I wanted to migrate database from 8i to 11g(8.1.5 to 11.1.0). I am going for exp/imp method. Which is the best method of doing this task? I mean Full export and Import Or Schemawise export and import? Is there any chances of missing objects or rows while doing this task? If yes, How to avoid? Please help me to take a best decision. I dont want any problem after migration.
Approach is (take exp of 8.1.5 and imp in 9.2.0) then (exp of 9.2.0 and imp it to 11.1.0.6)
OS is HP Unix

Using exp/imp appears to fail

Hello Everyone.
We are trying to export a set of table from one Oracle Database to another and have come across a problem.
Exporting via PL/SQL developer (v7) appears to be fine but when we try to import the generated .dmp file using the imp tool, it fails with this error:
IMP-00017: following statement failed with ORACLE error 905:
"CREATE TABLE "GEOM_TABLE" ("UUID" VARCHAR2(36) NOT NULL ENABLE, ""

ORA-00905: missing keyword
This only appears to happen when there is a reference to MYSYS.SDO_GEOMETRY. It is preventing the data migration from completing so does anyone have any ideas?
Thanks in advance.

Hi,
Table is based on type MDSYS.SDO_GEOMETRY (Spatial Data Types and Metadata), Check spatial is configured on your Target database and you have privilege to access that object using your schema.

Copy Page/region (incl. elements...) to application ( using exp/imp page) ?

question and enhancement request(!) -
some customers/prospects claim teamworking / reusable components. goal is to use a page (including its components like regions,processes,items,...) in another application - could realized by exp/imp if we can do it.
This would improve reusability and also teamworking.
I work together with a collegue on an application at htmldb.oracle.com. We exported the appl. and work on our local databases at different tasks by different pages.
But how we can reimport our results?

Lutz,
It's kind of difficult, but Raj described a procedure here: Synonyms
We are aware of the potential value of being able to copy pages between applications and are looking at ways to provide that in future versions of HTML DB.

How to upgrade a DB using EXP/IMP

Guys
I need to upgrade a small DB using IMP and EXP from 8i to 9i. Can you guys help me with the steps. Perhaps I was using the wrong search words, but I found no satisfying answers on google.
1. Recreate the target database TRGT with the correct tablespace definitions.
I need to query from dba_datafiles, dba_tablespaces, dba_temp_files?
2. EXPort the source database SRC
3. IMPort the dump file
I am little unsure of step #1. Can you help me with the details pls?
TIA

. Recreate the target database TRGT with the correct tablespace definitions.I need to query from dba_datafiles, dba_tablespaces, dba_temp_files?
Before starting the import,u need to create a fresh database on new 9i server.and create new tablespaces with same name that was present in 8i.after it u can start ur import with using ignore=y,otherwise it says following tablespace is already exists.
**import also automatically create the required tablespaces but if u want to change the storage attributes or location of dbf files ,its better that u create it manually before starting imp.

How to use exp,imp in oracle 8i version....

Hi developer ...
I am using oracle 8i version in windows xp platform. Can you please explain how to export and import my tables in to export.txt file.
with
Regards
sure...:)--

Hi,
Did you want to downgrade from 8i to 7.0, 7.3 and 8.0 ?
To downgrade, you need to use the export utility from the target database.
So, you will need three export files :
Run the 7.0 export to export from the 8i database, and import into a 7.0 database with the 7.0 import utility.
Same for 7.3 and 8.0 database.

Migrate oracle 9207 DB 8 TB size frm Solaris to AIX?dont want Exp/Imp

Hi Guys,PLz help
I want migrate 8TB oracle database from Solaris 8 to AIX 5.
In my last post on the same topic I was told to refer Metalink notes
291024.1,Note:77523.1,Note:277650.1
acc to these notes 'EXPORT/IMPORT IS THE ONLY OPTION TO MIGRATE FROM SOLARIS TO AIX'.
I was not convinced as In http://dba.ipbhost.com/index.php?showtopic=9523
I read
"As both solaris and AIX are UNIX O/S, cloning the DB is also possible from source box to target box"
Also
whats the role of "If the endianness is the same"??????
Can you guys plz comment on this again.....as I'm really confused because exp/imp of 8TB
is going to take half of my life :)
PLz tell in any other option in 9.2.0.7?If we have
Thanx

You can do
SELECT PLATFORM_NAME, ENDIAN_FORMAT
FROM V$TRANSPORTABLE_PLATFORMto check endianness of different platform.
-- Note, the view is only on 10g and above.
datafiles from different endian format can't be directly copied over and use. On 10g you have option to use RMAN convert endianness.
with that said, since Solaris and AIX are all big engianness. That means you can directly copy datafiles over and clone database without using exp/imp.
this article has a list of how to clone

Migrate exp/imp into data pump

Hi Experts,
we use exp/imp to exp data 150G and works to support stream in past time.
As I know, that data pump will speed up exp.
How to migrate ex/imp syntax into data pump?
my imp/exp as
exp USERID=SYSTEM/tiger@test OWNER=tiger FILE=D:\Oraclebackup\CLS\exports\test.dmp LOG=D:\Oraclebackup\test\exports\logs\exportTables.log OBJECT_CONSISTENT=Y STATISTICS=NONE
imp USERID=SYSTEM/tiger FROMUSER=tiger TOUSER=tiger CONSTRAINTS=Y FILE=test.dmp IGNORE=Y COMMIT=Y LOG=importTables.log STREAMS_INSTANTIATION=Y
Thanks
Jim

You are right - expdp more faster and useful than classic exp utility
There are several features in EXPDP
- may do only local on current server
- you must create directory object in database &
grant read,write priveleges to user
For Example:
create directory dump as 'd:\export\hr';
grant read,write on directory dump to hr;
Then we may do export:
expdp hr/hr DIRECTORY=dump DUMPFILE=test.dmp LOGFILE=exportTables.log
After export we will see two files in directory 'd:\export\hr'
Other features see from expdp help=y & Oracle Documentation
