Import schemas using data pump
Hi
I have taken full schema export dump using exp ..
(expdp username/password directory=dump dumpfile=scott.dmp schams=scott)
When i try to import this dump into another schema , i am getting the error user scott doesn't exist.. How to over come this.. put ur ideas and suggestions
following is the command i tried:
(impdp username/pasword directory=dump dumpfile=scott.dmp)
(impdp username/pasword directory=dump dumpfile=scott.dmp schemas=test)
Hi
You can watch the documentation for import.
http://download-east.oracle.com/docs/cd/B10501_01/server.920/a96652/ch02.htm#1005922
Think you have to use the "FROMUSER", "TOUSER" clause for import.
Hope it helps

EXPORT ONLY TABLES IN A SCHEMA USING DATA PUMP
Hi folks,
Good day. I will appreciate if I can get a data pump command to export only TABLE oBJECT in a specific shema .
The server is a 4 node RAC with 16 CPU per node.
Thanks in advanceIf all you want is the table definitions, why can you use something like:
expdp user/password direcory=my_dir dumfile=my_dump.dmp tables=schama1.table1,schema1.table2,etc content=metadata_only include=table
This will export just the table definitions. If you want the data to, then remove the content=metadata_only, if you want the dependent objects, like indexes, table_statistics, etc, then remove the include=table.

How to create/import a target schema from a source schema using data pump?
I have seen some examples where schema remapping will be done through remote link which I cannot as both the target schema and source schema are in same machine ...but I am not sure how to do it with out using remote link? I would be great if some one could provide a example
Thanks in AdvanceI'm not sure what you are asking here, but I'll try to give some examples on remapping a schema:
expdp prived_user/password schemas=orig_schema_1 directory=dpump_dir dumpfile=orig_schema_1.dmp
impdp prived_user/password schemas=orig_schema_1 directory=dpump_dir dumpfile=orig_schema_1.dmp remap_schema=orig_schema_1:new_schema_1
If you want to try without a dumpfile then you need a loop back dblink. (A dblink on your database that points to the same database. This would be your command:
impdp prived_user/password schemas=orig_schema_1 directory=dpump_dir network_link=loop_back_link remap_schema=orig_schema_1:new_schema_1
Hope this helps. If not, can you explain your question a little more?

What are the 'gotcha' for exporting using Data Pump(10205) from HPUX to Win
Hello,
I have to export a schema using data pump from 10205 on HPUX 64bit to Windows 64bit same 10205 version database. What are the 'gotcha' can I expect from doing this? I mean export data pump is cross platform so this sounds straight forward. But are there issues I might face from export data pump on HPUX platform and then import data dump on to Windows 2008 platform same database version 10205? Thank you in advance.On the HPUX database, run this statement and look for the value for NLS_CHARACTERSET
SQL> select * from NLS_DATABASE_PARAMETERS;http://docs.oracle.com/cd/B19306_01/server.102/b14237/statviews_4218.htm#sthref2018
When creating the database on Windows, you have two options - manually create the database or use DBCA. If you plan to create the database manually, specify the database characterset in the CREATE DATABASE statement - http://docs.oracle.com/cd/B19306_01/server.102/b14200/statements_5004.htm#SQLRF01204
If using DBCA, see http://docs.oracle.com/cd/B19306_01/server.102/b14196/install.htm#ADMQS0021 (especially http://docs.oracle.com/cd/B19306_01/server.102/b14196/install.htm#BABJBDIF)

Select table when import using Data Pump API
Hi,
Sorry for the trivial question, I export the data using Data Pump API, with "TABLE" mode.
So all tables will be exported in one .dmp file.
My question is, then how to import few tables only using Data Pump API?, how to define "TABLES" property like command line interface?
should I use DATA_FILTER procedures?, if yes how to do that?
Really thanks in advance
Regards,
KahlilHi,
You should be using metadata_filter procedure for the same.
eg:
dbms_datapump.metadata_filter
(handle1
,'NAME_EXPR'
,'IN (''TABLE1'', '"TABLE2'')'
{code}

How to export resource manager consumer groups using Data Pump?
Hi, there,
Is there any way to export RM Consumer Groups/Mappings/Plans as part of a Data Pump export/import? I was wondering because I don't fancy doing it manually and I don't see the object in the database_export_objects view. I can create them manually, but was wondering whether there's an easier, less involved way of doing it?
MarkHi,
I have not tested it but i think a full db export/import (using data pump or traditional exp/imp) may help doing this (which might not be feasible for you to have full exp/imp) because full database mode exports/imports SYS schema objects also, so there is a chance that it will also import the resource group and resource plans.

Migration from 10g to 12c using data pump
hi there, while I've used data pump at the schema level before, I'm rather new at full database imports.
we are attempting a full database migration from 10.2.0.4 to 12c using the full database data pump method over db link.
the DBA has advised that we avoid moving SYSTEM and SYSAUX objects. but initially when reviewing the documentation it appeared that these objects would not be exported from the target system given TRANSPORTABLE=NEVER. can someone confirm this? the export/import log refers to objects that I believed would not be targeted:

I suppose he already installed a software 12c and created a database itseems - So when you imported you might have this "already exists"
Whenever the database is created and software installed by default system,sys,sysaux will be created. -
Best Approach for using Data Pump
Hi,
I configured a new database which I set up with schemas that I imported in from another production database. Now, before this database becomes the new production database, I need to re-import the schemas so that the data is up-to-date.
Is there a way to use Data Pump so that I don't have to drop all the schemas first? Can I just export the schemas and somehow just overwrite what's in there already?
Thanks,
NoraHi, you can use the NETWORK_LINK parameter for import data from other remote database.

Using Data Pump when database is read-only
Hello
I used flashback and returned my database to the past time then I opened the database read only
then I wanted use data pump(expdp) for exporting a schema but I encounter this error
ORA-31626: job does not exist
ORA-31633: unable to create master table "SYS.SYS_EXPORT_SCHEMA_05"
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT", line 863
ORA-16000: database open for read-only access
but I could by exp, export that schema
My question is that , don't I can use Data Pump while database is read only ? or do you know any resolution for the issue ?
thanksYou need to use NETWORK_LINK, so the required tables are created in a read/write database and the data is read from the read only database using a database link:
SYSTEM@db_rw> create database link db_r_only
2 connect to system identified by oracle using 'db_r_only';
$ expdp system/oracle@db_rw network_link=db_r_only directory=data_pump_dir schemas=scott dumpfile=scott.dmpbut I tried it with 10.2.0.4 and found and error:

How to consolidate data files using data pump when migrating 10g to 11g?
We have one 10.2.0.4 database to be migrated to a new box running 11.2.0.1. The 10g database has too many data files scattered within too many file systems. I'd like to consolidate the data files into one or two large chunk in one file systems. Both OSs are RHEL 5. How should I do that using Data Pump Export/Import? I knew there is "Remap" option could be used, but it's only one to one mapping. How can I map multiple old data files into one new data file?
hi
datapump is terribly slow, make sure you have as much memory as possible allocated for Oracle but the bottleneck can be I/O throughput.
Use PARALLEL option, set also these ones:
* DISK_ASYNCH_IO=TRUE
* DB_BLOCK_CHECKING=FALSE
* DB_BLOCK_CHECKSUM=FALSE
set high enough to allow for maximum parallelism:
* PROCESSES
* SESSIONS
* PARALLEL_MAX_SERVERS
more:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28319/dp_perf.htm
that's it, patience welcome ;-)
P.S.
For maximum throughput, do not set PARALLEL to much more than twice the number of CPUs (two workers for each CPU).

P.S.2
breaking news ;-)
I am playing now with storage performance and I turned the option of disk cache (also called write-back cache) to ON (goes at least along with RAID0 and 5 and setting it you don't lose any data on that volume) - and it gave me 1,5 to 2 times speed-up!
Some says there's a risk of lose of more data when outage happens, but there's always such a risk even though you can lose less. Anyway if you can afford it (and with import it's OK, as it ss not a production at that moment) - I recommend to try. Takes 15 minutes, but you can gain 2,5 hours out of 10 of normal importing.

Can we load data in chunks using data pump ?
We are loading data using data pump. So I want to clear my understanding.
Please correct me if I am wrong on my understandings -
ODI will fetch all data from source (whether it is INIT or CDC ) in one go and unload into staging area.
If it is true, will performance hamper in case very huge data (50 million records at source) at source as ODI tries to load entire data in one go. I believe it will give better performance if we load in chunks using data pump.
Please confirm and correct.
Also I would like to know how can we configure chunk load using data-pump.
Thanks in Advance.
Regards,
Dinesh.You may consider usingLKM Oracle to Oracle (datapump)
http://docs.oracle.com/cd/E28280_01/integrate.1111/e12644/oracle_db.htm#r15c1-t2
In 11g ODI reads from source and write to target in parallel. This is the case where you specify select query in source command and insert/update query in the target command. At source side Odi reads records from source and add them to a data queue. At target side a parallel thread reads data from the data queue and writes to the target. So the overall performance would be the slower of the read or write process.

Exporting whole database (10GB) using Data Pump export utility
Hi,
I have a requirement that we have to export the whole database (10GB) using Data Pump export utility because it is not possible to send the 10GB dump in a CD/DVD to the system vendor of our application (to analyze few issues we have).
Now when i checked online full export is available but not able to understand how it works, as we never used this data pump utility, we use normal export method. Also, will data pump reduce the size of the dump file so it can fit in a DVD or can we use Parallel Full DB export utility to split the files and include them in a DVD, is it possible.
Please correct me if i am wrong and kindly help.
Thanks for your help in advance.You need to create a directory object.
sqlplus user/password
create directory foo as '/path_here';
grant all on directory foo to public;
exit;
then run you expdp command.
Data Pump can compress the dumpfile if you are on 11.1 and have the appropriate options. The reason for saying filesize is to limit the size of the dumpfile. If you have 10G and are not compressing and the total dumpfiles are 10G, then by specifying 600MB, you will just have 10G/600MB = 17 dumpfiles that are 600MB. You will have to send them 17 cds. (probably a few more if dumpfiles don't get filled up 100% due to parallel.
Data Pump dumpfiles are written by the server, not the client, so the dumpfiles don't get created in the directory where the job is run.
