Oracle Import/Export

Has anyone done Export/Import from Oracle 8i (8.1.5) to Oracle Ver 8.0.6. I went through the documentation. It says I have to use Export Utility Release 8.0 against Oracle 8i database. But this utility is not comes along with Oracle 8i. Does this mean I have to bring this earlier version of export utility from some other machine which is hosting the previous release??
Your suggesition are welcome..
Thanks in Advance..

What you can do is
Case 1:
if you have an 8.0.6 instance and an 8.1.6 instance running on separate Oracle homes at the same time, then
1.define a connect string to connect from the 8.0.6 instance to the 8.1.6 database.use the exp from 8.0.6 to connect using
username/password@connect_string816 and then export the data .This exported data can then be imported into the 8.0.6 database.
case 2:
You have only 8.1.6 instance up and running:
You will have to run the catexp.sql from an Oracle home that has the 8.0.6 software.this will create the required views to export data from the 8.1.6 database in 8.0.6 format.
Then export the data (this exported data will be in 8.0.6 format)and import it into the 8.0.6 database.
Hope this helps.

Suggestion regarding Oracle import & export utility

hi
I am navneet,I want to give some suggestion on Oracle import & export utility to Oracle Corporation. can u tell me where to send these suggestions

It would seem to me that if they are enhancement requests, then the right way would be to file an enhancement request. If they are bugs, then file SRs so bugs can be entered.

Windows/Oracle Import/Export

Hi,
is it possible to export a Database from Windows/Oracle 9.2 as a dump file
and import it then with Linux/Oracle 9.2?
If Yes, do i need any specific Oracle Client on Windows?
Thank You
Daniel

There is no problem with export dump file on cross platforms. The only restriction, is, you have to import either in the same version of oracle or higher version of oracle. You can't import into lower version of export dump.
You are using same oracle version, i.e. 9.2, it won't be any problem for export from windows and import on linux.
One more thing, if you ftp dump file to linux server, make sure you made through binary mode, otherwise, import will fail.

Attunity connectors for Oracle in Import Export Wizard in SQL Server 2008 R2

Is there a way we can see the Attunity connectors drivers in the Import/Export Wizard (64 bit) for SQL Server 2008 R2?
Although I made it work for SSIS, I would need these drivers in the Import/Export wizard so as to automate it for numerous number of tables which I want to migrate.
Can the Attunity connectors for Oracle be used in the Import/Export wizard? If so please let me know.
Regards,
Ashutosh.
Ashutosh.

I have 100 tables to migrate. Creating a data flow for each table is tedious and that's why I was looking out for a way to do it through import export wizard so that I don't have to create a separate data source and destination for each table in the Data
flow Task.
Is there a way to loop through all tables and transfer data in SSIS without having multiple sources and destinations created for each table? This also involves a bit of transformation as well.
Regards,
Ashutosh.

Problem of Data Import/Export after migration of Oracle DB 9i to 10g

We have encountered the following problem after the migration of Oracle DB 9i to 10g R1 and ESRI ArcSDE 8.3 to 9.1.
In our development server, a view was created by joining of one feature class (point feature), two attribute tables and one F table. We have to perform a process to export all the features in that particular view from the development server and then import them to the production server. In total, there should be about 60,000 points.
Form our past experience (using Oracle DB 9i and ESRI ArcSDE 8.3); we spent about 15-20 minutes to complete the import-export procedure. However, after the system migration, the speed of the import-export procedures is extremely slow, which is talking about 2 hours for ONLY EXPORTING 5MB data.
We would like to seek advice in solving the above problems. THANKS!

Try to delete old stats, then gather new stats on the schema and try the export again.

Is it possible to import an Oracle 10 (export .dmp file) into Oracle 9 db ?

hi Oracle Guru's
Is it possible to import a oracle 10 (export .dmp file) into an oracle 9 database ?
I tried & got the following error ...
IMP-00010 not a valid export file, header failed verificationperhaps their is a work-around ?
thanks

Hi
You can take export from a previous version and import to a later version. Having said that, there is still a workaround to do what you want.
On 9i server add a connect string for your 10g instance. Then use 9i export utility to export 10g data. That way your export will be compatible with 9i. You can then import the data in your 9i instance.
To create connect string you can either use Net Configuration Assistant or manually edit TNSNAMES.ORA file in your 9i server.
Hope it helps.

Import/Export-Tools for XML on Oracle-Lite

We have to import/export XML-Format on the Oracle-Lite-Database.
-Are there any tools available supporting Import and Export of XML-Data ?
-Can someone give us a recomendation how to perform XML-Imports/Exports if there is
no "out of the box-tool" available ?
Thanks.

So try. It is called Oracle XML-SQL utility and it set of classes for direct XML manipulation from/to database with HUGE amount of features. You can use it from JAVA and PL/SQL (via Java Stored Procedures). It is realy great.

Oracle Import and Export Utility

Hello All,
Could someone please explain me Oracle Import and Export Utility. I've gone through the below link and it has been mentioned to use keyword 'exp' but I'm not getting any idea where to use it. So kindly explain how the util works.

Hello;
Export creates a logical backup its great for move tables, schemas etc.
Import bring that data back in.
You can use a parm file with either.
Import example :
imp parfile=in.parm
in.parm ( contains )
userid=system/<password>
fromuser=scott
touser=scott
file=in.dmp
log=in.logemp parfile=out.parm
out.parm ( contains )
userid=system/<password>
owner=scott
file=out.dmp
log=out.dmp
statistics=noneYou can use these commands at the OS level to get quick help.
imp help=y
enp help=yYou can export a subset of a table :
exp scott/t<password> tables=emp query="where deptno=20"You can use options like :
full=y
BUFFER=2000000
GRANTS=y
COMPRESS=yThis utility is being replaced by data pump.

Application import/export failing, hopefully a simple one though

hi all,
i'm very new to oracle and am trying to get going with xe. i'm working between work and home and want to be able to transport wherever i'm at to work/home - so i thought the application import/export function would be the best way? first of all, is it?
if so - i keep getting the
failed to parse SQL query:
ORA-00942: table or view does not exist
error
i'm running the same versions of oracle, on the same platforms (Application Express 2.1.0.00.39, winXPpro all service packed up). both my users have dba roles and the apps work fine on the machines i created them on. the import and install processes claim to be successful and the error only comes up when i try to log in to the application. any ideas?
btw - the apps are just simple tests, dependences etc with a couple rows in each table]
any help be much appreciated even if its "go read this!" as i've googled away & got not much....
cheers!

Your problem is likely that in your office you do not have the tables required by your program. The export does not include your tables. You have to create them yourselves

Regarding Workflow 2.6.2 backup/migration/import/export

hi folks. i m quite amazed that this forum does not provide any answer to the question of taking backup of workflow 2.6.2 or import/export of owf_mgr schema. if one cannot take backup how this oracle workflow is stable. how this product is suitable for any organization. its a very basic requirement. ok its about processes and states.... but, even then i cant get the logic of not taking a backup. sometime we have to move data across servers
the only answer that i have seen for this is way back jan-09-2003 that its not possible yet. its now 2006 any one who can guide may be i got something or many a things wrong.

hi folks,
thanks for reply
Matt: considering ur statment para what i get for para 1
Full backup is fine - although there are some objects which are owned by SYS, as long as youare going from one database with WF installed to another one, you should be OK.
is
what i understand that u are talking about taking backup of entire database and not of just owf_mgr from export utility. if this is the case then do i really need to have owf_mgr user/schema installed where i have to import that backup
Secondly for Para 2
Runtime data is a different thing altogether, although I can't really see why you would want to migrate the runtime data from one DB to another.
what i get from ur description of Runtime data here, is about the data that represents different process states relavant data which is stored and maintained in different tables. Am I Right?
if the answer is yes then the answer to ur question (asked in the last line of ur statment) is that i dont want only runtime data to be exported rather i wanna export full user and its schema. and the reason from moving it from one server to another server is simply to have backup for the time of system crash or failiure
I am keenly anticipating ur reply

How to import/export in Pl/SQL ?

Hello
I want to write a procedure in PL/SQL which will be copying one user's schema to another.
I have Oracle 9i on Windows 2000.
My first idea was to use IMP EXP commands, but i need to execute this commands from PL/SQL procedure. How can I do this, except from writing Java procedure using Runtime class - I've done it, it works, but sometimes occure an critical error in Oracle Kernel, and I'm sure that Java code is ok.
Or maybe there is much easier way to solve such a problem (PL/SQL interface for import/export or something)?
Thanks for any hints.

No, imp/exp are standalone utilities with no PL/SQL API. Java would be the way to do it.

IMPORT & EXPORT from/to compressed files directly...

for newbies a tip to import(export) directly to(from) compressed files using pipes . Its for Unix based systems only, as I am not aware of any pipe type functionality in Windows. The biggest advantage is that you can save lots of space as uncompressing a file makes it almost 5 times or more. (Suppose you are uncompressing a file of 20 GB, it will make 100 GB) As a newbie I faced this problem, so thought about writing a post.
Lets talk about export first. The method used is that create a pipe, write to a pipe(ie the file in exp command is the pipe we created), side by side read the contents of pipe, compress(in the background) and redirect to a file. Here is the script that achieves this:
export ORACLE_SID=MYDB
rm -f ?/myexport.pipe
mkfifo ?/myexport.pipe
cat ?/myexport.pipe |compress > ?/myexport.dmp.Z &
sleep 5
exp file=?/myexport.pipe full=Y log=myexport.logSame way for import, we create a pipe, zcat from the dmp.Z file, redirect it to the pipe and then read from pipe:
export ORACLE_SID=MYDB
rm -f ?/myimport.pipe
mkfifo ?/myimport.pipe
zcat ?/myexport.dmp.Z > ?/myimport.pipe &
sleep 5
imp file=myimport.pipe full=Y show=Y log=?/myimport.logIn case there is any issue with the script, do let me know :)
Experts, please have a look...is it fine ? (Actually I dont have Oracle installed on my laptop(though have Fedora 6) so couldnt test the scripts)
I posted the same on my blog too. just for bookmark ;)

actually, only the compression thing runs in the background. rest proceeds like normal only. just instead of giving normal file we use pipe as a file.
nice article about named pipes

Questions on Import/Export Personalizations

Hi,
We are on 11.5.10 CU3. We have dozens of personalizations in Dev. I understand that Functional Administrator Import/Export tool can be used to transfer them from Dev to production. I am facing some issues when I try that.
1. I exported a personalization in Dev to the same instance java/custom. It created the directory structure java/custom..../site/0/ReqSummaryPG.
2. I imported it back. This was successful.
3. I re-imported it. It failed without an explanation for the failure. What could be the reason? Doesn't it just overrite the previous import - like when importing substituions?
4. I copied the custom/..../site/0 to another instance and imported it there. It was successful. However I could not see the personalizations.
5. So I checked. I realized that the directory structure was wrong. It was java/custom/apps/..../site/0
instead of java/custom/oracle/apps/..../site/0.
6. So I corrected the directories and re-imported. Failure like 3 above. I thought it was because of duplicate records. So i did the query select * from jdr_paths where PATH_NAME like '%ReqSummaryPG%'. I got only one record which was the seeded record. So eventhough 4 was successful there is only one record. Why?
Do I have to bounce Apache for each separate import of the same document?
Is there documentation on this utility with best practices? I see in the forum that no-one could successfully make this utility work.
Any help would be appreciated. I thought this was a simple utility ...
Thanks
Sandeep

Well this worked the next day! I reimported ReqSummaryPG again and it worked. I believe a few Apache bounces took place inbetween.
We were able to export/import quite a few personalizations. However, we got it right the first time this time around
I am still interested in knowing why a second consecutive import of the same doc doesn't work? And how to make it work? This would help in resolving issues in case of mishaps. Appreciate it if someone can provide an explanation.
Thanks
Sandeep
