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.

The export command i am going to use is as below.
exp system/oracle@ORCL1 file=schemaexp.dmp log=schemaexp.log owner=JACK rows=y direct=y
grants=N constraints=y COMPRESS=N buffer=100000000 RECORDLENGTH=64000
Is it possible to take this schema export in windows command prompt mode and any guess how long it would take to complete the export ?Because based on the time it takes, i am going to perform the export in windows command prompt.
I have two oracle 9i databases A and B with complete equal schema. Only the data is different. I want to import all table data from A to B. The problem is that there are duplicate primary keys. Therefore I want to insert data with new primary keys (all referencing tables are concerned too).

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.
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?
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 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'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.
Inside procedure,I need to validate all the columns (Ex:col1 should not accept more than 40 chars) and update status(containing error or not) of these columns into another column in the same table.For this,I mentioned only 'UPDATE' statements.So 'WHERE' clause of some update statements not using Primary keys.
In that table composite primary key was created.This procedure is successfully complied & executed now.But this procedure took more than 10 mins to execute.I need to reduce the time to less than a min.
How can I create a list of items in a field, for instance lets say I have a table called car and one of the sub categories is parts. How can I make it so that parts can be any number of pre-defined entities? Or even table, for instance if I make a table called parts how can I use that in the car table in place of parts?
My second question is about using foreign keys as primary keys. If I am writing an email sql DB and I decided to use the members usrname as the primary key in the member table but then made another table that lists all the emails and decided to make the foreign key member username the primary key there.
Is that safe to do or should i create a sequence in which to identify a primary key for the email list table? Also what if I extend member to several other tables and use it as a primary key there too, seems like a kind of dangerous way to do things...
is there any query to find number of primary keys present in a table.

The problem is when I use the SQL Plus command line to make SQL statements I can not get the previously typed command back at the prompt when I use the up and down arrow keys on my keyboard. This is quite easy when I am using a shell, but here with this Oracle command line interface it is not working at all. Here is the example as what actually is happening whe I press the up or down arrow keys.

etc.... i WANT TO EXPORT ONLY FEW TABLES IN THE SCHEMA
I was cloning a schema user1 as user2 in the same database.
user1 had quota on 2 tablespaces user1_data and user1_index.
I created user with name as user2.
I created tablespace user2_data only and granted user2 unlimited quota on that tablespace only (did not grant him 'resource' role or unlimited tablespace privilege) Now exported user1 schema as follows
exp system/<passowrd> file=/u05/oradata/dump/user1_schema.dmp log=/u05/oradata/dump/user1_schema_exp.log owner=user1 rows=y constraints=y triggers=y indexes=y statistics=none recordlength=65535 compress=no consistent=n grants=y
then imported in in user2 schema as follows
imp system/<password> file=/u05/oradata/dump/user1_schema.dmp log=/u05/oradata/dump/user2_schema_imp.log fromuser=user1 touser=user2 rows=y constraints=y indexes=y statistics=none recordlength=65535 grants=y

"REELISTS 1 FREELIST GROUPS 1) TABLESPACE "USER1_INDEX" LOGGING ENABLE "
. . importing table "table5" 0 rows imported
However, I checked that the T1_PK79 does not exist in the user2 schema though it exists in user1 schema Neither the index for priamry key (T1_PK79) existed in user2 schema not the table <table1> existed before this import Then what could be the reason that I am getting an error "IMP-00015: following statement failed because the object already exists"?
I assume tablespace for index would not be an issue here as other indexes got created properly in user2_index tablespace during this import.
I tried this twice, once with user2 schema and then with user3 schema as well (with different tablespace), but result is the same.
There were no users connected to the database during export and no background jobs were modiying any data in schema user1 while export.
I am using expdp command to export the table by specifying Query parameter. But i am unable to export the table based on the condition.

I ran "exp" command to take a back of Oracle Db based on user and later imported(using "imp" command) the dump into another db. Its seen that some the tables are not exported during exp command run. Can I use exp command on Oracle 11.2 version?
or should I always be using expdp command?
