Host Exp command

Dear Gurus,
I am trying to execute a command in PL/SQL as
EXECUTE IMMEDIATE EXP PWD1/USER1@TEST FILE=D:\USER1.dmpbut I receive error message as
ORA-00900: invalid SQL statement
how can I write a function/ procedure to take backup of database
*009*

yes, it exists in Oracle 10g and above.
In Oracle 9i you can call, from inside PL/SQL, an exernal procedure that runs host commands.

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.

Edited by: mithun on Jun 16, 2011 2:36 AMThis makes no sense whatsoever.
Now, as for your original question, there is not "host copy" command. Not in sqlpus, not in em.
What you are doing in sqlplus is the sqlplus command "host". That is a sqlplus command, documented in the SQLPlus Reference. The sqlplus command "host" takes an argument of an os command (in your case, the OS command is "copy") and creates a sub-process to ask the os to execute that command.
I can't even imagine what you are referring to when you say "when i configure host copy command inside em console". Can you explain in more detail?

How to use a subquery in query parameter in exp command

I am trying to export certain rows of a table using exp command
exp TRA/simple@TRA consistent=y indexes=n constraints=n tables=TRA$EMPL query=\"where deptid in $select objectid from Person$\" file=/dbase/dump/archv.2009-10-2917:24:00.dmp
but im getting an error
LRM-00112: multiple values not allowed for parameter 'query'
EXP-00019: failed to process parameters, type 'EXP HELP=Y' for help
EXP-00000: Export terminated unsuccessfully

On what OS you are trying to do that ?
What oracle version ?
Did you try to use parameter file ?
Have in mind that when using parameter file , special characters don't need to be escaped.

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.

To find whether a form using HOST (Unix) command to exit/execute a process.

Hi all,
I have some(Little bit) knowledge on forms.But here I got one requirement which was confusing me .The requirement is ,we have nearly 70 custom forms developed
using TEMPLATE.fmb.Now I have to open each and every form and have to check whether that form is using any HOST (unix) command to exit to the shell and
execute a process .I never got this type of requirement previously .Can any one help in how to search for those commands ,I.e is there any standard to use Unix call in
particular trigger or etc..
Thanks in advance .
Regards,
Gopi.CH

Your question is a little unclear. The "HOST" command is an Oracle Forms built-in command which allows you to execute OS commands. So the only part of it that belongs to forms is the part that looks like HOST(). The contents within the parentheses would be the command you wanted to execute. For example:
HOST('/path/to/your/script.sh');Refer to the Forms Builder online help for more information about how to use the HOST command.

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

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.

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.

Execute EXP command in SQL or PL/SQL window

Hi,
Sorry
Regards
Sanjit
Edited by: userSanjit on Jun 2, 2009 2:47 PM

You cannot use exp or imp commands from PL/SQL.
Why don't you use [DATA Pump|http://www.oracle-base.com/articles/10g/OracleDataPump10g.php]? If you are using 10g then you can easily incorporated that in your environment.

Appending data in dumpfile paremeter in exp command

Hi,
I have 10.2.0.1 installed on windows 2003 server.
I have taking hot backup using command.
Exp username/pwd FILE=C:\DataBaseBackups\3AMNEO.DMP LOG=C:\DataBaseBackups\3AMNEO.LOGwhich is working fine.
I made a batch file which have this code and this execute daily on a particular time and overwrite existing (i.e. last day) backup. But i don't want to do so.
I want to append data with file name so that every day it creates a new backup. (Do not over write existing backup.)
my aim is to take daily backup without overwrite existing backup automatically.
Thanks

Hi,
First thing is that Taking Export Based Backup is not the Consistent and not a valid Backup and not treated as Hot Backup. I suggest you not the follow this method.. !!
If my way of understanding is Correct If you are thinking about Cumulative Option that might work out
where An cumulative export backs up only the tables that have changed since the last cumulative.
For tht use the Options
FILE= cumulative01009.dmp
LOG= cumulative01009.dmp
INCTYPE=CUMULATIVE
I apologize I understood your question in different way.. !!
