Server Utilities :: Exporting Database Schema / Tables Without Data
Sep 22, 2010
I'm trying to export a relatively large database but it's a bit more complicated than that.For one schema I need a full export / import (data included).
For another 10 schemas I need them empty, with the exception of a table in some of them which needs to be exported / imported with all data inside.Is it possible to do this with datapump utility (impdp, expdp)?
Afterwards I will be running some scripts to populate the DB instance with critical data / metadata.
I am considering all of the capabilities and benefits of using Data Pump for exporting and importing extremely large data files. Would like to know if importing to tape is possible? If so, would the data be accessible if needed later?
extract a huge amount of data from a couple of views... the problem is that they want it in TXT files with fixed record length. There will be like 6 files, for a total amount of about 10GB.
export those tables in the fastest possible way? If I'm not mistaken exp and expdp can't create txt files, so do I really need to use utl_file or spool?

move the tables with data present in the user scott(full) to another schema named test. In my case scott is in user tablespace and for test schema i have created different tablespace named test_tbs.
Our Testing DB is running in No archive log mode. I did a schema level import by dropping the existing user that contain tables, recreate the user and finished the import. Now they want the old tables back.Is there is any way to recover the old tables?
I am trying to move data from one schema in database A to another schema in database B and only move data not others (procedure, view, function). What is the best way to do it? I am thinking database link then insert into select from database link. Is there a better way?
This message for my clarification,we have two schemas MAD_LIVE and MAD_TEST we want to take data from MAD_LIVE to MAD_TEST for particular period of time. way to import data from MAD_LIVE to MAD_TEST for particular period
My SCHEMA MAD_LIVE using from year 2010 till now,we want to take only 2012 data from MAD_LIVE and restore it in MAD_TEST.
I have exported data of one user an importing into another schema at another server. when i am trying to imoport it is working fine for quite no of imports into tables, but after some time it starts giving me below mention error...
IMP-00008: unrecognized statement in the export file: < IMP-00008: unrecognized statement in the export file: < IMP-00008: unrecognized statement in the export file: <ے IMP-00008: unrecognized statement in the export file: +A IMP-00008: unrecognized statement in the export file: [code]...
is it possible to remap the database schema during export?
Our developers have their databases stored within individual schemas and i want to provide a dumpfile that each developer is possible to easily import to his schema. But when i want to impdp the dumpfile i have to know the schema name within the dumpfile to do a remap to the individual developers schema -> so providing a specific schema name for within the dumpfile would be great.
At the moment i'm getting the ORA-39146, schema does not exist on importing the database..
How can i import whole schema from other database. i have a database WHO2 WHERE I HAVE A schema called stg_cupid_rp2 i want to import into data WH0T in stg_cupid_rp2 using DBlink EXP_SAT.
I imported a schema HR from export DUMP ....i can find all the objects of schema HR in the imported database... but i got an error for a plan_table which is assigned to USERS tablespace in the source database.. ...
HERE COMES THE ERROR I GOT DURING IMPORT:

I am exporting a table that is 3 GB in size and also Partitioned with option NOCOMPRESS specified.
Now when i export it with COMPRESS=N option of exp utility then it should take 3 Gb in target server but will exporting it with COMPRESS=Y will save some storage during import or once NOCOMPRESS option specified on partition has no impact on exp utility COMPRESS=Y option and it will take 3 GB space in both cases
Is this true that whether u specify COMPRESS=N|Y during export it does not matter the size will be 3 GB always after import?
I would like to export few tables from the physical standby which is in read only mode.
I have tried both the exp and expdp methods and could successfully export and import the tables from physical standby using exp unfortunately the expdp does not allow this process from a read only database.
Does this mean that we still have to use the exp feature instead of expdp ?
Note : I would expect a proper response from experts and no unwanted comments like "Contact Oracle support" or "Paste the entire command here" or "Read the Manuals" or "Why i am exporting from Standby and not from Primary" etc.
I am trying to export a partition of a table and import it to another database. I get the below error when I try to import.
ORA-14400: inserted partition key does not map to any partition
If I export the table(for that particular partition) and import the table(after dropping the table) in destination, the partitions and sub partitions are created without any problem.
The table is Range Partitioned and Sub partitioned in List. So I had to perform the below operation if I want to retain other data in the Destination table.
1. Drop the existing partition 2. Create the partition and sub partition, same as source 3. Execute imp
In fact I had to perform step#2, as if I split the partition also, the sub partition gets replicated in the new partition, which again throws the same error. Is there better way of managing the partitions and subpartition in destination with exp/imp utility, so that I need not perform step#1 and step#2 manually.
I have taken database backup using exp command and when I try to import in other pc the foreign keys are not imported. It saying error message that no matching unique key or primary key for this column.
how will i take backup including with primary keys?
Sunddenly my exports hangs at 'exporting cluster definitions'. I had been using this database since last 4 years and it never cause a problem or hangs at this level. here i'm pasting my screen details. it is my production db.

We completed creating a replicate of dB_01 to dB_02 (housed in a single DEV server). But dB_02 had only table structures (no records). What would be our fastest option (tools, commands, etc.) to load more than a thousand new records for each of the 20 tables of dB_02?
