EXP from UNIX to IMP in windows.

I have an export from UNIX of oracle 10.2.0.1.
I have taken backup with EXP utility of oracle.
I need to import that DUMP into windows with IMP command.
Is that possible?
Will it be successful?
Thank,

To open, view, unzip, decompress or uncompress a Gzip compressed archive file in Windows environment, a third party compression and decompression utiltiy or file archiver or data compression utility that supports Gzip archive file format is needed.
You should unzip, then transwer it to Windows to use it

Hi,
I have an export dump file which was taken from 11g database(11.2.0.2.0) and trying to import into lower version of the database 9i(9.2.0.6.0), unable to complete the process.
Two ways i have found and tested in my test db
1)TNS entry of 9i database has been put into 11g database
a)Export dump was successfuly taken from 11g db
b)Getting below error,while import into 9i database
IMP-00058: ORACLE error 6550 encountered
ORA-06550: line 1, column 33:
PLS-00302: component 'SET_NO_OUTLINES' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignoredIMP-00000: Import terminated unsuccessfully
2)TNS entry of 11g database put into 9i database version.
a)During export (trying to take exp dump from 11g db in 9i exp utility),getting below error
EXP-00008: ORACLE error 1455 encountered

Cheers,

Migrating from 9i to 10g through exp/imp

Hi,
We need to migrate a database on 9i in HP-UNIX to 10g in IBM AIX. Can you please tell me whether i can export data in 9i with 9i export utility and import it into 10g using 10g data pump utility for faster import ?
We don't have the 10g software installed in the HP-UNIX platform.
And what other alternatives we have to reduce the amount of time for the migration process as it's a critical Production database ?
Thanks,
Jayanta

I believe that Justin is correct that if you use exp to unload the data you will need to use imp and not impdp to reload the data.
To speed up the cross-platform exp/imp process I suggest you consider running multiple concurrent exp/imp jobs. You can generate a table=list into a spool file using sql. You can give each large table its own exp job and bunch the small tables.
Depending on how your database objects are organized you might also be albe to export by owner or a combination of owner, tables= exports.
You can use a full=y with the rows=n option to grab the public synonyms, non-owning users, packages, etc.... not brought in by the prior exp/imp.

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.

Step by Step EXP / IMP database from Oracle 9i to Oracle 11g

Please help on the captioned where I did the below
1. Use EXP to export the database from a Oracle9i database (O9_DB) OLD_Windows2003_SERVER
2. Install the Oracle 11g (default service name is ORCL) to a new Windows 2003 server and use the IMP to import the O9_DB, however, I need to create the same physical path as the OLD_Windows2003_SERVER (e.g E:\Oralce_9i\Ordata\) in order to complete the IMP
3. I can launch the SQL Developer and obtain the records count of evey tables being imported
However, is there any best / proper way to do the EXP/IMP, the ideal outcome would be
1. Create a new namespace say (OLDDB) which same as the Oracle9i database name so maybe I don't need to modify much on the application side to point to the new database ?
2. IMP the OLDDB to the new namespace OLDDB
Thanks in advance

Hello,
If you create the new Database on a new Server, you could keep the same name for the Database.
To switch from the old Database to the new one, you'll have to change the hostname on the "tnsnames.ora" or in any configuration file which define the database connexion.
About the best way to do the Export/Import, you may have some details on the link below:
http://download.oracle.com/docs/cd/E11882_01/server.112/e10819/expimp.htm#i262317
Else, why do you intend to stay on a Windows 2003 Server, why not moving to Windows 2008 ?
NB: Oracle *11.1* is certified on Windows 2008 and Oracle *11.2* is certified on Windows 2008 R2.
Hope this help.
Best regards,
Jean-Valentin

Once more on imp/exp on Oracle9i/UNIX

Suppose I have 4 huge tables (A, B, C, D) with parent child relationships enforcing using foreign keys and these tables have constraints.
How can I run multiple exp & imp to make the exp/imp faster?
Thanks.

Let me rephrase. I am willing to know what strategy needs to be taken with regards to index/constraints if I plan to run multiple exp/imp at the same time each exp/imp with a a set of (say 2) tables. Thanks.

Running OMBPlus and EXP/IMP in mixed version environment

OWB Mixed Environment Guru's
Current environment:
OWB Client: 10.1.0.2.0 on Windows XP Professional
OWB Server side: 10.1.0.2.0 on UNIX (AIX 5.2)
Repository: Oracle 9.2.0.4 on UNIX (AIX 5.2)
UNIX Listener: 9.2.0.4 on UNIX (AIX 5.2)
Runtime Repository: Oracle 9.2.0.4 on UNIX (AIX 5.2)
I call this a mixed environment since my OWB stuff is 10g and my database stuff is 9.2.
Issues:
1- I can't get the command line exp.sh script to connect to the repository and returns the famous 'ORA-12154, TNS:listener does not currently know of service requested in connect descriptor'. It looks like the 'owbsetenv.sh' script is changing the value of $ORACLE_HOME to point to the 10g areas. Could that be then causing the system to look for a 10g LISTENER which doesn't exist since all my databases are 9.2.0.4???
2- I have the same issue trying to run OMBPlus.sh.
I am ultimately trying to set up a promotion process using the UNIX command line programs (exp/imp and OMBPlus) to get objects from the TEST environment into the PRODUCTION environment which is a separate repository and target schema on a different machine.
Any advice on how to successfully operate in this 'mixed' environment is most welcomed.
Many thanks!
Gary

Well it looks like I did it again!
Total brain fart.
The problem turned out that I wasn't specifying the entire SERVICE_NAME for the repository database. I had been leaving off the domain information. Must be a habit from not having to use it in the TNSNAMES.ORA files.
I was able to compelte my test export and connect to OMBPLUS and will now try my test import.
Sorry to clutter the forum but if it helps anyone else with the same affliction I seem to have frequently, I guess that's a small reward.
Until next time.

Database shifting from UNIX to WINDOWS

Hi,
We have a production server located at Suse UNIX.
We would like to move database from UNIX to WINDOWS.
I would like to know what are the difficulties/scenarios which occures while moving the database?
How difficult is it to import current oracle database to oracle on windows server ?
Please explain in details.
Thanks,

hi what is your version of database?
are you chaging the database version also or simply operating system?
if you are only changing OS, then exp/imp is the best option. but to acheive this you need to do some groundwork like collecting all the tablespaces information and schemas and their privileges etc.
also depends on database size also you can choose come other options.
if your database version is 10g then you can best use the option of datapump exp/imp or network_link parameter of datapump.

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

Have you not yet completed this task? As we have already answered to your question a couple of days back.

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

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.

How to delete string or line from unix file(dataset) of application server

Hi All,
After transfer workarea information or all records into dataset(unix file). When I see the file in application server automatically the last line is shown a blank line. I am not passing any blank line.
I have tried for single record than also the file generates the last line(2nd line) also a blank line.
When I m reading the dataset, it is not reading the last blank line but why it is showing the last blank line?
How to delete string or line from unix file(dataset) of application server?
Please give your comments to resolve this.
Thanks
Tirumula Rao Chinni

Hi Rio,
I faced similar kind of issue working with files on UNIX platform.
The line is a line feed to remove it use
DATA : lv_carr_linefd TYPE abap_cr_lf VALUE cl_abap_char_utilities=>cr_lf.
DATA : lv_carr_return TYPE char1,
         lv_line_feed   TYPE char1.
lv_line_feed   = lv_carr_linefd(1).
lv_carr_return = lv_carr_linefd+1(1).
Note: IMP: The character in ' ' is not space but is a special
character set by pressing ALT and +255 simultaneosly
REPLACE ALL OCCURRENCES OF lv_line_feed IN l_string WITH ' '.
REPLACE ALL OCCURRENCES OF lv_carr_return IN l_string WITH ' '.
