Imp and Exp Command

Hi,
Pls explain me the concept of Imp/Exp command and the parameters assocoiated with it?If u can tell me online practicals for Import/Export command?
Regards
sudhir

At 8:03, you "wanna learn" about tablespaces and datafiles.
At 8:11 you want the concept of Imp/Exp explained to you.
At 8:10 you "wanna learn" the concept of Roll Back Segmenst [sic]
And at 8:12 you "wanna learn" all about SQL*Loader
Not bad for nine minutes of complete thoughtlessness, I suppose.
If you "wanna learn" all about Oracle, download the software, install it, start playing with it, and come back with some serious questions that show a modicum of thought, effort, persistence and care. Paying some attention to the usual rules of grammar and spelling might be an idea, too.
You'll find installations documented at http://www.dizwell.com/prod/node/695#installation, and then you can work your way through some concepts at http://www.dizwell.com/prod/node/263 and then you can start doing some basic fiddling at http://www.dizwell.com/prod/node/695#basics and once you've worked your way through that lot, you should be in a position to make sensible use of the stuff over at http://tahiti.oracle.com.
And after you've had a good read of the official Concepts book there, then you can come back here to ask specific questions and reasonably expect to get meaningful replies.

Improvements to imp and exp utilities

Hello all:
Does 10g release 2 address the issue surrounding the inability for exp and/or imp to handle blob datatypes? We have a database the uses a couple of blob columns and each time (using Oracle 9i) I exp my tables and try to imp them, the blob columns are not created.

workaround is to create the table with the blob column first and then run the import with ignore=y.
to generate the blob table script use
imp file=<filename> indexfile=c:\temp\create_table.sql tables=<blob table>

Imp and exp on diff version

hi
i have found problem in exp and imp in diff version of oracle
i have take exp in (Oracle8i Enterprise Edition Release 8.1.6.0.0) with no error
but when i imp this dmp on oracle personal edition
(8.1.5.0.0)
then it will gives error
is it possible to takes import data from higher to lower version.
thanks in advance.

Oracle does not allow to import data from higher version to lower version directly but you can do it if you take catexp.sql file from your older version and run that file in the Oracle Server where you have your higher version.
that file is found :
<ORACLE_HOME>/rdbms/admin
after you make the import you have to restablish your higher Oracle Server running catexp.sql beloged to that Oracle Server.

I will execute catexp7 on database 10g and after that I will take full export
and import the exported file on database 7.3.2.
If it is not right please could you correct me.

Running OMBPlus and EXP/IMP in mixed version environment

OWB Mixed Environment Guru's
Current environment:
OWB Client: 10.1.0.2.0 on Windows XP Professional
OWB Server side: 10.1.0.2.0 on UNIX (AIX 5.2)
Repository: Oracle 9.2.0.4 on UNIX (AIX 5.2)
UNIX Listener: 9.2.0.4 on UNIX (AIX 5.2)
Runtime Repository: Oracle 9.2.0.4 on UNIX (AIX 5.2)
I call this a mixed environment since my OWB stuff is 10g and my database stuff is 9.2.
Issues:
1- I can't get the command line exp.sh script to connect to the repository and returns the famous 'ORA-12154, TNS:listener does not currently know of service requested in connect descriptor'. It looks like the 'owbsetenv.sh' script is changing the value of $ORACLE_HOME to point to the 10g areas. Could that be then causing the system to look for a 10g LISTENER which doesn't exist since all my databases are 9.2.0.4???
2- I have the same issue trying to run OMBPlus.sh.
I am ultimately trying to set up a promotion process using the UNIX command line programs (exp/imp and OMBPlus) to get objects from the TEST environment into the PRODUCTION environment which is a separate repository and target schema on a different machine.
Any advice on how to successfully operate in this 'mixed' environment is most welcomed.
Many thanks!
Gary

Well it looks like I did it again!
Total brain fart.
The problem turned out that I wasn't specifying the entire SERVICE_NAME for the repository database. I had been leaving off the domain information. Must be a habit from not having to use it in the TNSNAMES.ORA files.
I was able to compelte my test export and connect to OMBPLUS and will now try my test import.
Sorry to clutter the forum but if it helps anyone else with the same affliction I seem to have frequently, I guess that's a small reward.
Until next time.

Imp exp commands

Hello!
I am a newbie in dataguard.
Til now the only backup procedure for the data was accomplished using the exp command on specific schemas.
Now we want to create a data guard environment but we want to continue using exp on the primary and imp on another server(not the standby).
Do the new configurations for data guard effect the exp procedure, I mean can we continue using exp on the primary as before without any problem?
Thanks in advance!

Uwe has made me think about more.
If you are asking will IMP/EXP still work then yes is the correct answer.
However since you state "only backup procedure" I went with the RMAN answer.
Also I assume you are speaking about the Primary database only.

ORA-12560 & imp\exp commands

When typing imp and supplying the login system along with my password I got the ORA-12560 error. After reading about the problem on the forums and the internet, I found that setting the sid with the command "set ORACLE_SID=" solved the issue. The problem is I would like not to have to do this every time I start Oracle after starting up my OS ( I have all the oracle services set to manual startup ). How can this be done ?
cheers

It seems you are on Windows. Set ORACLE_SID as environment variable (Control Panel ==> System ==> Advanced ==> Environment Variables). That works fine as long as you have only one database on your machine. You could also create a .bat file, which sets ORACLE_SID and starts service and database.

How to export datbase with exp command

Hi guys,
How to export oracle database using exp command without including tables space names.
I tried with this
./exp username/password file=db-export.dmp
./imp username/password file=db-export.dmp full=y ignore=y
But when I try to import database with separate login(username/password) its giving following error for some tables,
ORA-00959: tablespace 'MANUJA' does not exist
MANUJA is my username of first database
any help ?
Thanks
Best Regards,
Manuja

Option 1:
./imp username/password file=db-export.dmp full=y
If still error then :
Option 2:
pre-create your table then import with ignore=y option.
If still error then :
make sure userB just have one default tablespace (BC) and quota only on BC. So if you have unlimited quota for userB on all tablespaces, then objects will go to original tablespace and not the tablespace you want to put in(to default tablespace).
Revoke any unlimited tablespace privs from userB and just have one default tablespace.
REVOKE UNLIMITED TABLESPACE FROM USERB;
imp system/manager fromUser=userA toUser=userA file=myexport.dmp log=myexport.log

You should ask Oracle support for help. There's only one entry for this error stack (Bug 3361288 - Export of XMLSCHEMA may fail with ORA-24324 in UTF8), but it should have been fixed for your DB version and , as far as I can see, you don't have a Unicode database.

Avoid triggers in IMP or EXP

Hello,
How to avoid triggers in IMP or EXP.
TRIGGERS=Y/N is not available in 11g also.
Any other tricks?

No other tricks. With the data pump, you can exclude triggers on the impdp command line.

Incremental Export using EXP Command

Hi all,
I am trying to get incremental backup using oracle 9i "Exp" command. But this backup is being taken full of table data where changes made. Actually incremental backup should take a backup only the data last changes made.
Please help me, how can I take the real incremental backup using exp command.
Thanks
Khalil

should take a backup only the data last changes made.In order to be able to do that, Oracle would have to track rows that have changed since the last export. Think of a database with few hundred to a few thousand tables and tables with tens to tens-of-million rows.
In a table, a single column in a single row may have been updated.
However, in another table 40 columns in 3million rows may have been updated since the last export.
In another table, some rows might be deleted. (how would "incremental" compute the difference between "there were 1000 rows yesterday, there are 942 rows today")
In a fourth table, 3million rows have been inserted since the last export.
Can you conceive of the scale of "tracking" that Oracle would have to do if you want "only the last changes" to be exported ? Next, how would you "merge" data from two exports when you import them -- e.g. if the non-primarykey columns have been updated ; or primarykey has been updated ; or the table has no primarykey ?
The only way an "Incremental" change can be identified is by tracking if any change (whether 1 columm in 1 row or all the columns in all the rows) has been made to the table since the last export. If a single byte has been changed in the table, the whole table will be exported.
Are you sure you were able to use Incremental Export in 9i ? Incremental Export is documented in 8.1.7 but hasn't appeared in the 9.2 documentation.
The 8.1.7 documentation says "+An incremental Export backs up only tables that have changed since the last incremental, cumulative, or complete Export. An incremental Export exports the table definition and all its data, *not just the changed rows*. Typically, you perform incremental Exports more often than cumulative or complete Exports.+ "
Oracle had announced the end of Error Correction Support for the Incremental Export effective 31-Dec-1999. It ended Extended Assistance Support 31-Dec-2002. See Oracle Note#170483.1 on the support site.

Generating the .CAP, .JCA and .EXP files.

Hello;
I have downloaded the java_card_kit-2_1_2 to ‘C:\java_card_kit-2_2_1", and I tried to compile HelloWorld application that shipped with its distribution. I was successfully able to compile the file HelloWorld.java, but I am having lots of problems in generating the .CAP, .JCA and .EXP files.
I tried to follow the instructions in jcdk2.2.1 user guide, but of no use.
This is what I am basically doing:
_Step1) Setting my Environment Variables as follows:_
*set JC_HOME=C:\java_card_kit-2_2_1*
*set JAVA_HOME=C:\Program Files\Java\jdk1.6.0_16*
*set PATH=.;%JC_HOME%\bin;%JAVA_HOME%\bin;%PATH%*
_Step2) Compile the java file_
The package of HelloWorld.java is : src.com.sun.javacard.samples.HelloWorld, so to compile I use the following command line:
*javac -g -target 1.1 -source 1.3 -classpath .\classes;..\lib\api.jar;..\lib\installer.jar src\com\sun\javacard\samples\HelloWorld\*.java*
_Step3) Converting_
I have the class file generated in the package folder: src.com.sun.javacard.samples.HelloWorld, I generated an .opt file as follows:
+-out EXP JCA CAP+
+-exportpath .+
+-debug+
+-applet 0xa0:0x0:0x0:0x0:0x62:0x3:0x1:0xc:0x1:0x1 src.com.sun.javacard.samples.HelloWorld.HelloWorld+
+src.com.sun.javacard.samples.HelloWorld 0xa0:0x0:0x0:0x0:0x62:0x3:0x1:0xc:0x1 1.0+
Finally, the command line for conversion is:

*"%JAVA_HOME%\bin\java" -classpath %_CLASSES% com.sun.javacard.converter.Converter -config src\com\sun\javacard\samples\HelloWorld\HelloWorld.opt*
After successfully executing all these lines, I get the following error:
Java Card 2.2.1 Class File Converter, Version 1.3

*+error: class HelloWorld does not belong to package src.com.sun.javacard.samples.HelloWorld.+*
conversion completed with 1 errors and 0 warnings.
PLEASE HELP! I also tried adding -classdir to the opt file, but still did not work.
The whole point behind this exercise is to import a javacard framework of version 1.0
Really appreciate anyone's help! Thanks in advance.

Thank you Shane, but my claSs file is indeed saved in "C:\java_card_kit-2_2_1\samples\src\com\sun\javacard\samples\HelloWorld"
Now since I am running my command lines from C:\java_card_kit-2_2_1\samples, so I guess that the class directory is:
src.com.sun.javacard.samples.HelloWorld
Right?
