You should Read The Fine Utilities Manual found at http://tahiti.oracle.com which completely documents the IMPORT (imp) utility

Hi,,

I have 3 files of dmp files and also one file as import.par.

"exporting table AES_EXPOSED_DEVICE_UPDATE 34 rows exported"
Above is one of an example contained in one dmp file.

Below is the content in the import.par file:

rows=Y

tables=(AES_ADDL_HISTORY_AUDIT,AES_ADDL_HISTORY_DATA,AES_ADDL_HISTORY_UPDATE,AES_ADDL_INFO_AUDIT,AES_ADDL_INFO_DATA,AES_ADDL_INFO_UPD ATE,AES_CEV_DRUG_AUDIT,AES_CEV_DRUG_DATA,AES_CEV_DRUG_UPDATE,AES_CLINICAL_EVENT_AUDIT,AES_CLINICAL_EVENT_DATA,AES_CLINICAL_EVENT_UPDA TE,AES_CODES_DEV_AUDIT,AES_CODES_DEV_DATA,AES_LAB_DATA,AES_LAB_UPDATE,AES_REPORTER_AUDIT,AES_REPORTER_DATA,AES_REPORTER_UPDATE,AES_RE PORT_AUDIT,AES_REPORT_DATA,AES_REPORT_UPDATE)

I am supposed to import with these files.
I would appreciate if you could tell me the steps I should follow.

Thanks,

Above is one of an example contained in one dmp file.


If above is content then it is not dump file it is log file.
because dump file is binary file and you cann't read easily in text editor.


e:\>exp system/oracle parfile=e:\>import.par log=path

Hi,

I have a cd with 3 dmp files ind_co.dmp, ind_mo.dmp, ind_po.dmp
and 3 text files ind_co,ind_mo,ind_po.
"exporting table AES_EXPOSED_DEVICE_UPDATE 34 rows exported"
This example is from one of the text file.

And along with these 6 files in the cd, there is also one import.par file as I mentioned earlier. So, if i am understanding you correctly, is ind_co(text file)is it a log file????

Since I have the export dmp files, my thinking is to ftp these dmp files from my system into the database and then import the same. Please correct me if i am wrong. Also, if you could provide me with the steps i would appreciate it.

Thank you very much

It looks like those "text" files really are export log files. If all of them have only one "exporting table TABLE_NAME n rows exported" line, it means that every export file contains only one table.

You can always check it; it is important that you have access to the database server (so that you could import data into); if you have access to the server itself, fine - you have IMP.EXE too. But, if your database is somewhere else, you'll have to have Oracle Client installation (which should include Oracle Utilities - one of them is Import Utility).

To see what is in any export file (.DMP), simply issue (at the operating system prompt) such a command:

OS> IMP username/password FILE=export_file.dmp SHOW=Y

SHOW parameter will only list contents of the export file. Now, if there are several tables, you can choose to import all of them, or some of them. First option is done by

OS> IMP username/password FILE=export_file.dmp

while only some of them are imported using

OS> IMP username/password FILE=export_file.dmp TABLES=(first_table, second_table, third_table)

That should be all; if you are about to FTP those DMPs, you must use BINARY mode (otherwise, import might not be able to read it).

Finally, no matter what we say, perhaps you should read the Export and Import (Data Pump) utilities user's guide (just like Anacedent already told you). That would be the right way to learn why and what to do.

Which version of Oracle made the *dmp files?
Into which version of Oracle should the *dmp files get imported?
(Versions to 4 decimal places, please)

Thanks very much all. Those info were really helpful.
The dmp files were generated by Oracle 8.1.7.4.
I have to imp the files in the same version.
Lastly one final question, do I have to know in which schema I have to import the data?

Thanks,
Geetha

It is depand on you.
before import any schema plz run catexp.sql scripts.
above script create neccassary view and grant priviliges.
-----------------------------------------------------------
first import all three dump file and after that you have also import.par parfile.
if your parfile
see my earilar post how you import parfile.
--------------------------------

first try if you getting any error plz post here.

remember for every import operation please create log file with log parameter.

Do I have to know in which schema I have to import the data?

Imports are usually done for some reason. One of them is, for example, that you accidentally dropped a table and now you are restoring it from the export file.

In my opinion, yes - you should know where to import those tables(1). Schema is identified by user's name (it is "username/password", the part of the IMP command).

@Taj: as both export and import are using the same database version (8.1.7.4), is it necessary to run CATEXP.SQL? Wouldn't import work as it is?

_______
(1) ... unless it is a full database export, performed by a privileged user. Then you don't care what belongs to who, because IMP will do the job for you - create users, import objects, etc.

Even then, if a privileged user uses full database export but imports only one user, you should know it in order to specify FROMUSER and TOUSER parameters.

Hi,

I am sorry that I started with a new topic. I got the error as netowrk connection out, I figured out the problem is with the network it kicked me out of the session after a few minutes. But now I am trying to run the import.sh as

nohup import.sh &

By running the script at the background, will it take even longer???? When i typed this above command,it showed with the following line and never proceeded further for 20mins:

sending output to nohup.out

please give me your suggestions.

If you are running the import remotely and you are having network issues, then you need to resolve the unstable network prior to performing the import. If you are telneting to the remote box and kicking off the import with nohup, then the import should finish in the same time as if you telneted to the box and kicked the import off without the nohup.

How big is the dump file that you are importing?

Hi,

I dont know how to find out how big my dump file is. But I am sure its pretty huge. Dmp file is the export of production backup. There is 16734669 rows in it. Now the import is half the way thro'.. but its been 1hr 15mins now since it started importing system_audit_trail table(has 12875459 rows in it)..
Not sure if it got stuck or if there is anything else wrong with it..there is no error in the alert log.. and in the nohup.out file i see as below

. . importing table "SYSTEM_AUDIT_TRAIL" [artee01]/appl/oracle/
admin/eg/export>

Please give me your suggestions.
Thanks,
Geetha.

Hi,
ORA-00020: maximum number of processes (150) exceeded


Increase you PROCESSES parameter. this parameter is not dynamic parameter you have to shutdown and startup your database like
---------------
shutdown immediate;
First edit in your pfile 
found >>> oraclehome/dbs/init<sid>.ora
increase PROCESSES parameter.
create spfile from pfile;
startup normal;

hi,

I have 3 dmp files with same tablenames but different number of rows exported for each table in all three files. I imported 2 dmp files to user eman. Imported successfully.
But the 3rd dmp file(with same table names as the other 2 dmp files but different number of rows exported),when I imported the 3rd last file, import completed successfully except 1 table

It gave the below error

..importing table "audit_event"
IMP-00058:ORACLE error 904 encountered
ORA-00904:invalid column name
Import terminated successfully with warnings.

What I wonder is, the same table got imported successfullly when I imported the 1st two files which had the same tablename.
Now I dont know why it is not importing when I import the 3rd dmp file.Please give me your suggestions.

Thank you.

Hi,

Yes. The table structure changed when the 3rd export was taken.
Thats the problem. Since I have already exported the same tablenames with rows, I am not going to worry about this dmp file anymore. Thanks for all your help guys.
