Oracle Exp/Imp Utility

If i do a full export from on database instance and import to a new instance, will that import the entire data and create tablespaces and users into to the instance?

Nobody, really has addressed your question in a proper manner.
If i do a full export from on database instance and import to a new instance, will that import the entire data and create tablespaces and users into to the instance?
Yes ideally it should & it will !!!
But there are few things that take it away from the ideal scenario.
When you take export of a database, it creates a dmp file and that contains all the information to create the same database...like information to create tablespace, users, db links, procedure...blah blah....
But...there are few things that need some attention.
One thing is tablespaces: That dmp file contains the SQL statements to create all the tablespacs in the database. It also includes the exact path of datafiles. Lets say my database A is on Machine1 and datafiles lie in c:\oracle\DB_A\*.dbf. Now when I run the import (in different database, on same or different machine) it will try to create the tablespaces with datafiles with the same name & on the same location as in database A. But that wont be possible in the case if you are importing to the database which is created on the same machine. Why ? As obviously you will have to keep the datafiles in different directory.
But if its on different machine, then its possible to use the same path for datafiles. But again be warned ! those directories should exist before you run the import.
Second thing is db links: For a db link to work you need to have entry of remote database in the tnsnames.ora file. If you are on the same machine and using the same ORACLE_HOME, you are done.
But with "different ORACLE_HOME on same machine" or different machine, you will need to make the entry of all the remote database [being used in DB Links] in the tnsnames.ora file.
Just few points, I have summed up. Might be I have missed something that may come up as an issue.

  • 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.

  • How exp/imp behave

    how exp/imp utility will behave when i'll try to migrate data from oracle 8i to 10g when the platform and file system will be different.
    what should be the procedure to that?

    I’ve had to do this recently. You just need to use the 8i exp from the 8i Oracle home for the 8i database to create your dump file. Then, use the 10g imp from the 10g Oracle home to import the dump file into your 10g database. Import is backwards compatible – it will read dump files created by older versions of export. And this is the best way to move from one platform to another.

  • Exp/imp problems

    Hi,
    Kindly Help.
    I plan to export full the database then I'll import it back to the same database, my purpose is to fix the fragmentation of the tables/tablespaces.
    1. Before importing the export file should I do anything to the database( e.g. truncate the tables, delete the contents)?
    2. Does the exp/imp utility depend on the SGA for it's performance or if not the SGA what parameter should I change to speep up the exp/imp?
    Thank you

    I plan to export full the database then I'll import
    it back to the same database, my purpose is to fix
    the fragmentation of the tables/tablespaces. Why you using export/import to de-fragmentation, there are other ways to do same like rebuild indexes, Use LMT etc

  • Exp/Imp Lmitations??

    Does any body know if there is any limitation in Exp/Imp utility in dealing with LONG RAW columns?
    Regards,
    Kumar.

    I assume you are using the 309 version of portal. It is possible to export out an entire content area or a page but not the granular items. By granular I mean just the folder in this context. If you wish to export/import the entire content area/page, you can run the pageexp/pageimp/contexp/contimp scripts which reside in the WWU directory.

  • Exp/imp data pump

    I exported tables in 10g using exp(normal export)command
    Can I user impdp(datapump) while doing import

    There is no exclude or include option in the traditional export/import (exp/imp) utility. This is only given in datapump (expdp/impdp) to exclude or include the database objects while exporting or importing.
    All you can do as work around is, create the structure of the table in the target database/schema, then do import, while import if the table is found in the target schema, then that table will not imported. So, don’t use ignore=y, if you use, even if the table is found during the import, the rows will be imported in fact. Hope you got what I mean.

  • Exp/Imp In Oracle 10g client

    Hi All,
    I want to take one schema export from Oracle 10g Client. I am in new Oracle 10g.
    In oracle 9i, we can using exp/imp command for Export and Import from Client itself.
    I heard about in Oracle 10g, we can use Expdb/Impdb in Server only. Is there any possibility to take exp/imp in Client also.
    Pls help me...
    Cheers,
    Moorthy.GS

    To add up to expdb from oracle client
    NETWORK_LINK
    Default: none
    Purpose
    Enables an export from a (source) database identified by a valid database link. The data from the source database instance is written to a dump file set on the connected database instance.
    Syntax and Description
    NETWORK_LINK=source_database_link
    The NETWORK_LINK parameter initiates an export using a database link. This means that the system to which the expdp client is connected contacts the source database referenced by the source_database_link, retrieves data from it, and writes the data to a dump file set back on the connected system.
    The source_database_link provided must be the name of a database link to an available database. If the database on that instance does not already have a database link, you or your DBA must create one. For more information about the CREATE DATABASE LINK statement, see Oracle Database SQL Reference.
    If the source database is read-only, then the user on the source database must have a locally managed tablespace assigned as the default temporary tablespace. Otherwise, the job will fail. For further details about this, see the information about creating locally managed temporary tablespaces in the Oracle Database Administrator's Guide.
    Restrictions
    When the NETWORK_LINK parameter is used in conjunction with the TABLES parameter, only whole tables can be exported (not partitions of tables).
    The only types of database links supported by Data Pump Export are: public, fixed-user, and connected-user. Current-user database links are not supported.
    Example
    The following is an example of using the NETWORK_LINK parameter. The source_database_link would be replaced with the name of a valid database link that must already exist.

  • 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

  • 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,

  • EXP & IMP only restores to same tablespace(s)

    Hi All...
    I created new user with new tablespace and import dmp to new user
    but the import utility imported same tablepspace (increase old datafile size).
    even I dropped new user but the old tablespace (datafile) size not reduced?
    Sudhir

    Normal behavior.
    Using conventional exp/imp the correct method to 'relocate' an user is
    - make sure the target user doesn't have unlimited tablespace privilege by revoking it
    - make sure the user doesn't have quota on the old tablespace and does have quota on the new tablespace
    alter user <target user> default tablespace <new tablespace> quota unlimited on <new tablespace> quota 0 on <old tablespace>
    - Now import with indexes=n
    - run a second import using the parameter indexfile=<any filename>
    - Edit the resulting file, changing all tablespaces
    - now run the file in sqlplus
    - this should be it
    Using expdp and impdp, remap_tablespaces on impdp is sufficient

  • The imp utility fails to import triggers

    After making a complet export of a user of Oracle 10g Database, data, procedures and triggers, when trying to import the user to a other database ,with the imp utility, all go fine except the triggers and some procedures. ¿Why? Because ,in anyway, the imp or the exp utility, I dont know, append the character '"' at the end of the lines.
    I think that maybe it can be by the NLS, because the imp utility say me, 'the export was done in USS7ASC and ALFT16.. and the import is weiso8859...'. But I dont know.
    ¿Any Help?.
