You should just be able to call the "imp" and "exp" executables ($ORACLE_HOME/bin) using the Runtime class. You can setup the various parameters for export / import in a parameter file.

Scripting oracle export and import dumps through PLSQL stored procedures

Hello,
I would like to know if it is possible to script oracle export and import dump commands in a PL/SQL package rather than at command prompt. Also, how can i copy the export dump files across the network to a specific location.
I would really appreciate if someone can provide me with examples????
OR
If there is off the shelf solution for what i am trying to achieve?
Many Thanks.

Hello,
there are many ways to do this:
- Java with PL/SQL wrapper,
- call C code as external procedure from PL/SQL,
- DBMS_SCHEDULER has some features related to this as well,
- or write your own logic: for example creating a new file with UTL_FILE could be the trigger of the export.

Yes, there's DBMS_JOB on 9i, it's sort of DBMS_SCHEDULER's 'grampa' ;)
Check the 9i docs (http://tahiti.oracle.com) and do some searches here and on http://asktom.oracle.com for more info.
Hoewever, in order to execute OS-commands, you'll probably need a JAVA wrapper.
DBMS_JOB cannot do that.
Examples can be found here:

Oracle Export and import

Hi,
I just want to do the export and import.
Source DB - Oracle 10g on Solaris 64 bit OS. (Export)
Destination DB - Oracle 9i on Windows OS (import).
Kindly confrm that these export and import is possible in oracle.
Thank you,

add version=9.x while taking the export from solarisThat advice doesn't apply for 10g to 9i.
The export has to be done with the 9i "exp" binary, from a 9i ORACLE_HOME. It can be done over a SQLNet connection.
The subsequent import has to be done with the 9i "imp" binary.

Oracle Export and Import of XE application

I am trying to do an Oracle Export of an EX application and an Import to another PC. Can it be done?
I have encountered several problems. Either it brought over the application, but no Pages or I cannot access the Login page.
My reason for this is to handle application updates/changes for 50 odd remote users.
I am using APEX Release 2.1.0.00.39

Yes it was a full database export with all schemas.
I ran the following query before and after the import:
select object_type, count(*) from dba_objects where owner = 'FLOWS_020100' group by object_type order by 1;
After the IMPORT, I had less LOBs (4) and Tables(8).
The missing tables are:
DR$WWV_FLOW_OH_IDX$I
DR$WWV_FLOW_OH_IDX$K
DR$WWV_FLOW_OH_IDX$N
DR$WWV_FLOW_OH_IDX$R
DR$WWV_FLOW_OH_PT_IDX$I
DR$WWV_FLOW_OH_PT_IDX$K
DR$WWV_FLOW_OH_PT_IDX$N
DR$WWV_FLOW_OH_PT_IDX$R
The script below was used to reinstate the SYS grants to flows_020100:
Select owner||':'||table_name||':'||privilege from dba_tab_privs where grantee='FLOWS_020100' and grantor='SYS';
The results from the script:
grant SELECT on SYS.OBJ$ to Flows_020100;
grant SELECT on SYS.USER$ to Flows_020100;
grant SELECT on SYS.V_$SESSION to Flows_020100;
grant SELECT on SYS.V_$PARAMETER to Flows_020100;
grant SELECT on SYS.V_$TIMER to Flows_020100;

FYI:
When I Imported this last time, I Imported by users. Three imports statements for each user flows_020100, flows_files and apex_public_user (XE_DBA).
imp system/passwrd file=g:\common\xe\xedba_full.dmp ignore=y fromuser=flows_020100 touser=flows_020100 log=c:\flows_logs.log
imp system/passwrd file=g:\common\xe\xedba_full.dmp ignore=y fromuser=flows_files touser=flows_files log=c:\files_logs.log
imp system/passwrd file=g:\common\xe\xedba_full.dmp ignore=y fromuser=xe_dba touser=xe_dba log=c:\xe_dba_logs.log
as opposed to my initial IMPORT:
imp system/passwrd file=g:\common\xe\xefull.dmp ignore=y
FYI: I am not getting the Err-1016 "4550" Page "1" not found error. It now lets me log in , but there are[b] no applications. It should have been 5 applications.
Hey, in typing the above statement, I realized that my login page is "101" (default) and Page "1" is a data entry page.

Export and Import Utilities

guys,
Does the import and export utilities come with the client install or do you have to install oracle database to be able to use import and export utilities.
Thanks

If you are using Windows the path to bin should something like below, it will be different depending upon the OS and directory structure you chose during Client installation.
In the DOS prompt(if in windows) go to the below directory and type exp help=y
C:\oracle\10.2.0\bin;
or see the path environment variable(MyComputer-->Advanced --> Environement Variables) is set to the above directory. If not set this variable.
In unix or linux you can export the above path variable or go to the $ORACLE_HOME/bin directory.
Eg:
C:\oracle\10.2.0\BIN>dir imp*
Volume in drive C is Local Disk
Volume Serial Number is 103F-E6B3
Directory of C:\oracle\10.2.0\BIN
08/29/2005 06:26p 212,992 imp.exe
08/29/2005 06:31p 114,688 impdp.exe
2 File(s) 327,680 bytes
0 Dir(s) 20,294,348,800 bytes free
C:\oracle\10.2.0\BIN>dir exp*
Volume in drive C is Local Disk
Volume Serial Number is 103F-E6B3
Directory of C:\oracle\10.2.0\BIN
08/29/2005 06:26p 471,040 exp.exe
08/29/2005 06:31p 114,688 expdp.exe
2 File(s) 585,728 bytes
0 Dir(s) 20,294,348,800 bytes free
C:\oracle\10.2.0\BIN>exp help=y
Export: Release 10.2.0.1.0 - Production on Thu Dec 7 14:10:56 2006

You can let Export prompt you for parameters by entering the EXP
command followed by your username/password:
Example: EXP SCOTT/TIGER
Or, you can control how Export runs by entering the EXP command followed

Now I still get the "BIG QUESTION", could I export and import database using stored procedure???
Really thanks for the response.

Hi,
I think you can use DBMS_DATAPUMP (10.1+), see [DBMS_DATAPUMP|http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28419/d_datpmp.htm#i1007277], for examples see [http://www.psoug.org/reference/dbms_datapump.html]

Export and import table data with Java

I need a library for simple exporting and importing table data.
The data should be exported to a SQL file with insert statements.
I just want to tell the library the table name, the connection and where to store the file. The usage should be very simple.
Are there any small libraries for this? Finished calsses and methods which I can just call?

I need a library for simple exporting and importing
table data.
The data should be exported to a SQL file with insert
statements.Every database has utilities to export/import data from tables. Take a look at your database manual.

Steps to export and import oracle 10g databse from AIX to AIX and LINUX

Hi,
I need the steps to export the oracle 10g database from AIX server to AIX server and LINUX server.
Please give me all the steps as this is my first exort an import activity.
thanks,

For 10g there exist two ways to do so.
1) Regular exp/imp.
2) Data pump expdp/impdp.
As this is your first export and import activity, relevant concept understanding is mandatory for you.
Documentation Link
http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14215/toc.htm
Read the chapters 1,2,3 (Data pump expdp/impdp) and 19 (regular exp/imp). Good luck.

Export and Import in Oracle

I need to export users with tables and data from Oracle 8.0.4 and import into Oracle 8.1.7.
But the condition is that we need to retain the Japanese characters.
I did this using simple export and import functions but Japanese characters were imported as Junk.
Can somebody tell me what is the clean way of exporting and importing such that Japanese charaters are not converted to Junk.

You must set the correct characterset before exporting and importing (I don't know which characterset is correct for you, but choosing the same characterset as the characterset of your database should work).
Use NLS_LANG environment variable to do this,
NLS_LANG=<LANGUAGE>_<TERRITORY>.<CHARACTERSET>. On UNIX if NLS_LANG is not set explicitly, it defaults to AMERICAN_AMERICA.US7ASCII, that means all special characters cannot be translated.
On Windows NLS_LANG is set at installation time, it corresponds to the settings of Windows itself.

Doc ID: Note:10767.1
Subject: How to perform FULL System Export/Imports
Type: BULLETIN
Status: PUBLISHED
Content Type: TEXT/X-HTML
Creation Date: 18-APR-1994
Last Revision Date: 30-AUG-2002
Purpose
This article highlights some important points to consider when performing
a Full System Export and Import.
Scope and Application
It is intended to assist users performing FULL System Exports and Imports.
A Full System Export and Import is a useful way to replicate or clean up
a database. Please note the following guidelines when performing a Full
System Export and Import:
1. When performing the import, ensure you are pointing at the correct
instance. Always check values for the SID and two task driver before
proceeding.
*Note: On Unix systems, just entering a sub-shell, such as using
C-shell, can change the database that the import would work
against.
2. When possible, it is advisable to take a physical copy of the
exported database and the database you intend to import into before
starting the import. This ensures any mistakes are reversible.
3. NEVER run a FULL SYSTEM IMPORT on a machine that has more than one
database UNLESS you are 100% sure all tablespaces have been
pre-created. A full import will create any undefined tablespaces
using the same datafile names as the exported database. There are
situations where this is very dangerous:
-> If the datafiles belong to ANY other database, they will be
CORRUPTED. This is especially true if the exported database is
on the same machine, because its datafiles will be re-used by
the database you are importing into.
-> If the datafiles have names that clash with existing operating
system files.
4. When exporting, it is advisable to also produce a report showing
information you may need before / after the import:
-> List the tablespaces and datafiles
-> List the rollback segments
-> List a count, by user, of each object type such as tables,
indexes, etc.
This enables you to ensure that tablespaces have been pre-created
and to check the success of the import after it is complete.
5. If you are creating a completely new database from an export, remember
to create an extra rollback segment in SYSTEM, and make this available
in the init.ora file before proceeding with the import.
6. There are some versions of export that do not retain sequence numbers
correctly. It is advisable to select next_value for each sequence
after the export so that these can be checked after import.
Following these guidelines will help you to avoid major problems.

Subject: How To Copy an Oracle Database To Another Machine
Type: HOWTO
Status: PUBLISHED
Content Type: TEXT/X-HTML
Creation Date: 12-OCT-2001
Last Revision Date: 01-OCT-2003
goal: How to copy an Oracle database to another machine
fact: Oracle Server - Enterprise Edition
fix:
Pre-requisites: The copy is between 2 machines, both have to be on the same OS
and have to have exactly the same database version installed.
1. Make sure the database you want to copy was closed with a SHUTDOWN IMMEDIATE,
SHUTDOWN NORMAL or SHUTDOWN TRANSACTIONAL.
2. Copy init.ora and control files to create instance and be able to go in
mount mode. Check the init.ora for the locations where the controlfiles have
to be, if those locations are not valid on the machine put the control files on
different places and adjust the init.ora accordingly.
3.a. Copy the datafiles (all of them).
b. Copy the redo-logfiles (all of them).
4.a. (Unix only) Set the environment variables:
ORACLE_SID - set to the database name you wish to create
ORACLE_HOME - set to full pathname of the Oracle system home directory
PATH - needs to include $ORACLE_HOME/bin
b. (NT/2000 only) Do 'set ORACLE_SID=<SID>'
Use oradim to create the service for the instance. For more information
on oradim please refer to (the part that refers to creating a new instance):
Note:68720.1 Creating a new 7.3, 8.0, 8.1 Instance/Database
5. Use servermanager (check the name to use for your version of oracle) or
sqlplus (version 9i and above) to startup the database in mount mode.
Do
CONNECT INTERNAL/<PASSWORD>
then
STARTUP MOUNT
Then do a rename of the copied datafiles if they are not in the same path as on
the other machine. For all the files that are in the result of the query:
SELECT NAME FROM V$DATAFILE;
do
ALTER DATABASE RENAME FILE '<oldfullpath>\<filename>' to <
newfullpath>\<filename>';
6. Query the datadictionary for the old location of the redolog files using:
SELECT MEMBER FROM V$LOGFILE;
If the new place is not the same as the old do:
ALTER DATABASE RENAME FILE '<oldfullpath>\<redologfilename>' to &
lt;newfullpath>\<redologfilename>';
7. Now open the database:
ALTER DATBASE OPEN;

Guide me for exporting and importing data from oracle 10g to oracle 9i

I have been trying export and import options in oracle but m not very clear about the procedure..
Also when i am logging in as Scott/tiger i am facing an error
ORA 1542 - tablespace 'USER' is offline and cannot allocate space in it.how to resolve it

Hello,
I see two questions.
ORA 1542 - tablespace 'USER' is offline and cannot allocate space in it.how to resolve it About the error ORA-01542 you have to bring the Tablespace USERS online:
http://www.error-code.org.uk/view.asp?e=ORACLE-ORA-01542
If you cannot bring it online you may have to Recover it first.
I have been trying export and import options in oracle but m not very clear about the procedure..About the Export in 10g and Import in 9i (9.2 or 9.0.1 ?), you have to export with the Export utility of the Target Database (the lowest Database version here: 9.0.1 or 9.2) then, you have to Import to the Target Database using its Import utility (in 9.0.1 or 9.2).
The following Note of MOS may guide you:
Compatibility Matrix for Export And Import Between Different Oracle Versions [Video] [ID 132904.1]
NB: You cannot use here the DATAPUMP.
Hope this help.
