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 taking export using consistent parameter. Theoretically i can understand . practically i couldn't understand how it works.
for ex
I am updating tab1 table under sams user. table having one lakh records.
while updating the query using consistent=y and consistent=n. i mean
exp sams/sams file=cons.dmp owner=sams consistent=y
exp sams/sams file=cons2.dmp owner=sams consistent=n
then both files imported to separate user(sam ,san).
Updated info not visible in san and sam user.
I want to know practically how it works. I need perfect example. while using consistent=y and consistent=n

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?

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..

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.
