Hi

so should i use expdp(datapump) or exp(orignal export).
yours sincerely

xml ... ?That one I have no idea. Try it and see. Test and verity your result. Know what to expect, and don't be surprised if you ... find something you were not expecting.
connected to a schemaOne does not connect to a schema, connections are opened to a database instance. A schema is a collection of database objects.
entry form but no body is using it ...That is an entirely different subject, try a google with the search terms rdbms acid test.
In oracle, the only session (connection) that can "see" updates is the updating session. No other session may sees those changes until the transaction is committed to the database. Until the commit, all other connections see the "before" value.
Queries that begin before other transactions commit see the before values, oracle keeps the old value in undo. So an export will "see" the values committed as of the time the export begins.

Thanks in advanceHello,
You wrote:
CAN THIS ERROR CAUSE BIG DESASTER TO DB IN FUTUREThe error message EXP-00091: Exporting questionable statistics just warns you that the statistics
were exported but these statistics may be not useable.
So, if you have to import these Tables, you may have to collect again the statistics of these Tables.
It's not relative to this problem but why don't you use DataPump (expdp/impdp) ?
Please find enclosed a link about DataPump, it's much more powerful than the classical export/import:

Check the status expdp datapump job
All,
I have started expdp (datapump) on size of 250GB schema.I want to know when the job will be completed.
I tried to find from views dba_datapump_sessions and v$session_longops,v$session.But but all in vain.
Is it possible to find completion time of expdp job?
Your help is really appreciated.Hi,
Have you started the Job in "Interactie mode".. ??
If yes then you can get the status of Exectuion with "STATUS"- defauly is zero (If you setting to not null value then based on that it will show the status - seconds)
Second, thing check "dba_datapump_jobs"

Using expdp to do a schema export is taking extremely long time
I am using expdp in schema mode to export a 300 gigbyte database.
The job status report 99% complete after about 2 hours .
But now the job has been running 30 hours and is not finish.
I can see that it is exporting the domain indexes and had been exporting
the last index for the last 5 hours. Something is not working because I
looked at the table the index is using and it has no data. So, why is it taking
so long to export an index that has no data?
Can someone tell if there is a way to bypass exporting indexes and a easy way
to recreate the indexes if you do?
I am using oracle 11g and expdp utility.I checked the log file and there are no errors in the file.
There are no ORA- xxxx error messages.
The last line in the log file is as follows:
"Processing object type schema_export/table/index/domain_index/index "
I just checked the export job run this morning and it is still on the same
index object "A685_IX1" . This is a spatial index. It has been sitting at
this same object according to the job status for at least 24 hours. -

MathewMay we know the database version of your exported and imported database ? I believe that , you trying to import into lower version of database. If yes, then loging as a sys and run the script $ORACLE_HOME/rdbms/admin/catexp.sql .

When Im perform export it terminated unsuccessfully with bellow message,please clarify why is this
EXP-00008: ORACLE error 1555 encountered
ORA-01555: snapshot too old: rollback segment number 3 with name "_SYSSMU3$" too small
EXP-00000: Export terminated unsuccessfullyI'm going to assume you are running an older version of Oracle? 9i? And/or that you use manual rollback segments?
I've had that error before when running an export because my export was running for longer than the database was keeping the undo blocks that I needed to read from. Our export was running for 6 hours, so you need to ensure that it can have a read consistent view of the data as of 6 hours ago. If using automatic undo management, which I would recommend, you can set the undo_retention to 6 hours. -

Oracle UserHi,
>>because I exported dump from oracle10G
Then you use the exp 10g version, right ? To move data DOWN a version(s), you need to export using that lower versions EXP tool and using IMP that lower version tool.
Take a look at this below?

Expdp (Datapump) question
Hi,
I am using the following expdp command to create database export for one of my schemas. The issue is when I run it manually on command window, it creates 2 files 'EXPORT01.dmp' and 'EXPORT02.dmp' which is exactly what I want. However, when I run the same command from the batch file it creates only one file: EXPORTU.dmp and runs out of space as I have limited the space to only 3m. Why does the same script not run in the batch and creates 2 files (export01.dmp and export02.dmp)?
Here's my command:
expdp system/password SCHEMAS=myschema LOGFILE=EXPDP_LOG_DIR:EXPORT.log DUMPFILE=EXPDP_DATA_DIR:EXPORT%U.dmp FILESIZE=3m
Please help.
Thank you.Because when You run it from script it can't correctly parse "%" character. You need to solve it, try
DUMPFILE=EXPDP_DATA_DIR:EXPORT\%U.dmp FILESIZE=3m
backslash before % on most os it must work -

Table created by datapump imp/exp, change default tablespace?
Is there a way, without changing the users default tablespace, to force the table created by data pump import or export to go to a different tablespace than the users default? Our policy is that users must declare the tablespace they want an object created in, therefore the users tablespace is very small (6M), so if they accidently created an object in this TS it would fail. When we run expdp, this default tablespace fills up and export fails. I can't find a parameter in the documentation on giving an alternative tablespace for this table.
When you run expdp, it creates a table under the user you logged in as. This table is used to keep track of the datapump process. I am looking for a way to direct datapump to create this table in a specific tablespace instead of the users default.

Using exp to export part of a table
Hi, can anybody help with how to export a portion of a table using exp?
Ive tried the following but it errors.
Table(T) or Partition(T:P) to be exported: (RETURN to quit) > test.table where user = 'john'
Does exp work like this or do i need to export the whole table?
ThanksNot really. What I posted is all there is to it. I suggest you open the Utilities manual for your version of Oracle and look at the chapter on exp for more information. The query must apply to every table in the export, if you are exporting more than one table.
Actually if you are on 11g pulling the 9.2 manual (available online) might be a better manual since the utilities manual now spends most of its coverage on expdp.
The expdp utility also has an ability to filter tables based on a query.

TDE (Encryption) and expdp (Datapump)
Hi,
I'm testing TDE's features on an Oracle 10g R2 database. I edit the sqlnet.ora then I created a wallet on database 1 (DEV1), a table, did inserts, pumped (expdp) data and tried re-import it in another database (DEV2) which I use with DataGuard for failover, but something went wrong. So I try re-create my wallet on the first database (DEV1) by alter system set wallet close and delete it from my hard drive and drop table purge. I went trought the whole process of creating the wallet and table but when I tried expdp I got the ORA-28362 master key not found.
How could I not be able to export my data ? What can I do to do a clean deletion of the wallet and recreate it ?
Thanks for you help
FrancisThank you,
but I already read those pages and understand them. But as I said, even though I delete and recreate the wallet, I can't get datapump to extract data with the ENCRYPTION_PASSWORD parameter. If I don't put this parameter everything is ok! but the data is not encrypted. -
