Import in oracle 10g

Sir
I am using Oracle 10g(10.2.0.1.0).I am using export and import utility for backup.
Now the problem is that i want to set some password when any sys or system or othere dba user want to import that dump file require password.So that my dump is secure and nobody outside my company will able to import the file.
Thanks

I wonder why people keep thinking export is a backup. The documentation is quite clear about it: Export is NOT a backup, it is only a logical dump.
When you use export as a backup, you will loose data when a disk crashes, and you have to 'restore' your database from an export.
Using export for a backup is a potential career limiting move.
Also you shouldn't need to ask whether you can password protect an export. Obviously such feature is documented (Oracle has no undocumented features) and you can read about it in the documentation, in this case the Oracle Utilities Manual.
You can encrypt an export made with expdp, Oracle's new tool, and with RMAN.
But you really should stop using 'export for a backup', and start using RMAN, right now, or the day will come you will regret you didn't use RMAN.

    Also please post Oracle source and destination version. Whether regular export/import or datapump is used ?

  • Export from Oracle 9i to be Imported into Oracle 10g on 32bit platform

    Hi,
    Currently, I am in the process of performing a Homogenous system copy
    due to a domain change in our organization using R3load procedure.
    I have taken the export of the existing system which is on Oracle 9i.
    Initially, I was planning on setting up the new system on Oracle 9i,
    now that Oracle 9i is out of support, I would have to go with Oracle
    10g.
    I found a note on this topic, SAP Note: 932722, however, this note
    explicitly talks about database specific procedure of system copy and
    also this note is for 64 bit platform.
    Can you point me towards a Note or documentation which can be used as
    reference for importing an Oracle 9i export into Oracle 10g on 32bit
    platform(System copy procedure is R3load)?
    OS- Windows 2003 32bit, ECC 5.0
    Regards,
    Vishnu.

    Hi Gagan,
    Thanks for your response,
    As per your suggestion, I looked at the System Copy guide for Heterogeneous System Copy,
    On service.sap.com/osdbmigration under FAQ's this is what I found,
    I plan to copy my SAP system to a new hardware with the same OS and DB products but higher release levels. Is this a migration or a homogeneous system copy?
    A change of the version of the operation system and/or the database system is not relevant in the context of a migration or a homogeneous system copy. If you don't change the product, but only the release level it is a homogeneous system copy. If you change OS and/or DB, it is a migration.
    The system copy guide, doesn't explicitly talk about an export from Oracle 9i imported into Oracle 10g.
    Can you point me to a guide or Note?
    Regards,
    Vishnu

  • Oracle 11g- Straing behaviour of query after importing from Oracle 10g

    Hi,
    I have a table in Oracle 10g as follows:
    Create Table xyz (col1 varchar2(50), col2 varchar2(50));
    With following Data
    Col1     Col2
    A     320
    A     110
    A     290
    A     380
    B     ABC
    B     256
    B     LMN
    I am running following Query
    select * from xyz
    Where Col1='A' and Col2=110
    It works fine. But when I export this table and import it in Oracle 11g. It says invlid identifier.
    But if I enclose 110 in single quotes. It works fine.
    Also If I recreate this table in Oracle 11g like
    Create table xyz1
    as select * from xyz;
    Now alos I am able to run this query smoothly.
    select * from xyz1
    Where Col1='A' and Col2=110
    What is wrong exporting this table from 10g to 11g.
    Any comments/suggestion??
    Aarbi

    The check in your where clause
    Col2=110Is comparing a string (Col2 is defined as a VARCHAR) with a numeric literal, so there will be an implicit conversion taking place from character to number. The query then fails due to the B LMN row when 'LMN' fails number conversion.
    I'm guessing there was there an index on the table in your 10g installation which would allow the query to be satisfied without checking the B ABC or B LMN rows but is not present or not used in the 11g installation so a full table scan results in an attempt to convert 'ABC' and 'LMN' to a number. Check the explain plans.
    Or it could even just be a difference in the order in which the two conditions in the where clause are evaulated between the two versions.
    The solution, as you have already found is to do a string comparision
    Col2='110'Edited by: Cyn on Dec 7, 2009 12:38 PM

  • 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.

  • Important differences between oracle 10g and 11g

    Hi friends, can anyone tell me (pointwise) what are the major (and minor) differences between Oracle 10g and 11g.
    Please point me to some documents if possible.
    Thanks in advance

    The name of the link says it all: "top_features."
    In short it is Oracle's list of what they have for marketing and sales reasons designated "top features."
    It is not intended to be, and is not, a complete list of features. Often the features Oracle does not
    talk about are the most important.
    Let me give you some examples. I have never seen Oracle announce DBMS_XPLAN as a new feature
    yet you should not run an explain plan without it. Neither have I ever seen Oracle announce the new
    NO_DATA_NEEDED predefined exception. I have listed literally hundreds of new features you will not
    find in Oracle's new features docs.
    I did a presentation at OpenWorld this year as part of the unconference titled "New Features in
    Database 11gR2 that Oracle will not announce." It was easy to prepare a one hour presentation with
    little fear of being proved incorrect. As I turned out only one of the features I presented was mentioned
    by Oracle.

  • Problem in importing data in oracle 10g from 9i backup

    Hi ,
    Am trying to import data in oracle 10g..but it does not importing constraints, and stop doing anything by the msg.
    About to enable constraints.....
    after this msg it does not work.
    plz help,
    Regards,
    Neha

    Hi Neha,
    You have a lot of options. I'll supose you can test first, and you're using an export file.
    First forget about the data, think in your database structure. So you can do this:
    exp userid=... file=exp_norows.dmp full=y rows=n statistics=none
    Now you have the structure of your database. Create the database, in 10g, empty, check you have all filesystem, etc. for you new datafiles. And do the import with parameter ignore=y, you'll see a lot off errors on SYSTEM schema, don't worry about it.
    Now you have the structure of you database in 10g. You can take a look in the import log file, looking for some possible errors come from your schemas. so check the objects, and check the schemas.
    Bear in mind things like CONNECT role in 9i it's different in 10g, you can't create db_links in 10g with "IDENTIFIED BY VALUES" because you'll get an ORA-00600, etc.
    Well, fix all problems on source database (9i) and repeate this procedure until you don't recieve any more errors (not a SYSTEM schema errors).
    When you have everything solved, you can try to import the data.
    I hope, this method can help you. If you have any problem do not hesitate to ask me.

  • Need help for importing oracle 10G dump into 9i database

    hi, Someone help me to import oracle 10G dump into 9i database. I'm studying oracle . Im using oracle 10G developer suite(downloaded from oracle) and oracle 9i database. I saw some threads tat we can't import the higher version dumps into lower version database. But i'm badly need help for importing the dump...
    or
    someone please tell me the site to download oracle 9i Developer suite as i can't find it in oracle site...

    I didnt testet it to import a dump out of a 10g instance into a 9i instance if this export has been done using a 10g environment.
    But it is possible to perform an export with a 9i environment against a 10g instance.
    I am just testing this with a 9.2.0.8 environment against a 10.2.0.4.0 instance and is working so far.
    The system raises an EXP-00008 / ORA-37002 error after exporting the data segments (exporting post-schema procedural objects and actions).
    I am not sure if it is possible to perform an import to a 9i instance with this dump but maybe worth to give it a try.
    It should potentially be possible to export at least 9i compatible objects/segments with this approach.
    However, I have my doubts if this stunt is supported by oracle ...

  • Can I import a tablespace into Oracle 10g Express Edition

    I am very new to Oracle 10g Express Edition. We have a server running Oracle Enterprise Edition and we have been creating a transportable tablespace to be imported into a few servers. This works fine for us. I would like to find out if I can import the tablespace into Oracle 10g Express Edition. Someone told me that I should be able to do that but I have no clue to how to do it. If this is possible, can someone tell where to find the information how to do this.
    Thanks,

    I finally tried it and I got the following errors:
    IMP-00017: following statement failed with ORACLE error 721:
    "BEGIN sys.dbms_plugts.checkCompType('COMPATSG','10.2.0.2.0'); END;"
    IMP-00003: ORACLE error 721 encountered
    ORA-00721: changes by release 10.2.0.2.0 cannot be used by release 10.2.0.1.0
    ORA-06512: at "SYS.DBMS_PLUGTS", line 2004
    ORA-06512: at line 1
    IMP-00000: Import terminated unsuccessfully
    Am I right that the server that I exported the tablespace is using Oracle 10.2.0.2.0 while Oracle Express is 10.2.0.1.0? I looked around and I did not see Oracle Express version 10.2.0.2.0 that I can download. Is there a patch or something to upgrade it?

  • Oracle 10g Data Dump---Import to different users

    Hi everybody,
    I exported data in oracle 10g using expdp in user schema(abc1).
    Now i want to import that data in different user schema (abc2) and another user schema (abc3). Both schemas (abc2 and abc3) are in same tablespace.
    How to do this. Shall i need to export that data in SYSTEM mode to import for different users..?
    Thanks in advance
    Pal

    Shall i need to export that data in SYSTEM mode to import for different users..?No need. You can use REMAP_SCHEMA option on import, e.g.
    impdp system/<password> directory=<directory> dumpfile=<dumpfile> remap_schema=abc1:abc2
