How to migrate data from one database to another for a specific time frame

Hi
This is the scenario:
We have 2 databases:
PTT : THis has data from march 11 to March 19 that was created when the production was down due to a crash
PROD : THis was recovered after March 19. Hence has no data created between March 11 and March 19
How do I transfer this data from March 11 to March 19 from PTT to PROD so that Production can be up to date asap.
Please let meknow the methods to get this done
Regards
Gayathri

Hi,
You could use EXP/IMP to move the data from PTT to PROD. But, you should be careful with sequences, modification to the same data.....
eg Customer Address was updated between Mar 11 - 19, again the same customers was updated after 19 Mar, under this situation if you load the data from PTT you would be wrongly updating the data.....
You have to study well and apply changes...........

How to move data from one database to another one?

I 'd like to build up a new database, some of the data would come from an old database, then I have to make two connection objects to both databases, (two statement objects...) retrieving the data from the old one and inserting them to the new one.... sounds reasonable, huh? but it could not work this way... "........it would have caused the duplicated value , blah, blah..." even though I made two tables in two databases completely different, that errors are still there. seemed I cannot clone that table.
could you guys have any better ideas? and why couldn't I go this way?
the database: cloudscape3.01
two databases are all on my local PC (WinNT4.0)
thanks

If you are getting dupicate record errors, then look at your recordset objects and make sure they are both pointing at seperate databases, and check the one you are using to output and make sure it isn't just writing NULL, if it is then trace up the line: your input (read) recordset may be reading NULL too.

How to move data from one database to another oracle database

Hi
All,
AIX 5.3
Oracle 10.2.0.3
I want to move data between one oracle database to another oracle database.
I know two method those are
export/import
dblink
is there any other way I can move data?
Thanks,
Vishal

I know below methods. However, using a perticular method is based on volume and type of data.
1. imp/exp
2. impdp/expdp
3. SQL COPY command
4. Transportable tablespace mathod
5. dblink
6. Export to flatfile and then use SQL Loader
7. Oracle Migration Workbench

How to move only subset of data from one database to another?

Both source & destination are Oracle11g databases.
The requirement details are as below,
1) The database contains static as well as transactional data for telecom domain.
2) We have to move region-wise data from one database to another.
3) There are around 10 regions.
4) The region wise data extraction from source db is based on around 40 to 50 tables. Rest of the tables contains
static data & it will not change.
5) The volume is around 1 million subscribers per region.
6) The migration is required because
a) The client is upgrading its base product which uses this database
b) There is a change in structure of static tables
c) Hardware upgrade
d) The client want to start with single region on new database & rest of the regions will be operated from old
database.
7) Keep execution time to very minimum.
I am thinking to have solution as below,
1) Create destination database with upgraded db structure (as mentioned in 6b)
2) Create database links to access source db in destination db.
3) Write SQL queries to fetch data from all the respective tables for a specific region
4) Write separate PL/SQL blocks for each table to fetch data from source db & insert into respective table in
destination db
a) Use FOR ALL & bulk collect to improve the performance
b) Divide table data into multiple chunks & execute parallel batches (around 10) to insert the data
5) Validate pre & post counts to verify the success of migration
Is there any other better way?

How to move only subset of data from a partiular table by using transportable tablespace?
E.g. SUB table using SMP_SUB tablespace contains subscriber data in source database.
The indexes defined on SUB table are under SMP_IDX_SUB tablespace
The subscribers data can be categorized by different regions, say region_id column. Then how to move data & indexes of SUB table from source db to destination db?
any specific example would be helpful.

Transfer data from one database to another without identities but keep the relation b/w PK and Foreign key

Hi,
I need to transfer data from one database to another database (both are identical databases).
1. Not transferring identity columns (primary keys). the destination table might have the same key.
2. keep the PK's and FK's relation b/w parent and child table
3. I have 4 levels
Example: tableA (col1 int identity(1,1) , col2, col3)
tableB (col1 int identity(1,1) ,
col2 , col3) -- col2 has the foreign key relation with tableA.col1
tableC (col1 int identity(1,1) ,
col2, col3) -- col2 has the foreign key relation with tableB.col1
tableD (col1 int identity(1,1) , col2, col3) -- col2 has the foreign key relation with tableC.col1
please advise me.
Thanks in advance

Try the below:
/********************************SAMPLE TARGET***************************************************************/
Use MSDNSamples
create table TableA(LevelValueId int identity(1,1) primary key, name varchar(100))
Insert into TableA(name) Select 'R1'
Insert into TableA(name) Select 'R2'
create Table TableB(ChildId int identity(100,1),name varchar(100), LevelValueID int references TableA(LevelValueId))
Insert into TableB(name,LevelValueID) Select 'Childname1',1
/********************************SAMPLE TARGET***************************************************************/
/********************************SAMPLE SOURCE***************************************************************/
Use Sample
create table TableA(LevelValueId int identity(1,1) primary key, name varchar(100))
Insert into TableA(name) Select 'C1'

Insert into TableB(name,LevelValueID) Select 'Kidname1',1
/********************************SAMPLE SOURCE***************************************************************/
USe MSDNSamples
/********************************MIGRATION INTERMEDIATE TABLE***************************************************************/
--Migration table
Create table Mg_TableA(LevelValueId int, NewValueId int)
/********************************MIGRATION INTERMEDIATE TABLE***************************************************************/
/********************************ACTUAL MIGRATION FOR MASTER TABLE***************************************************************/
MERGE INTO TableA
USING sample.dbo.TableA AS tv
ON 1 = 0
WHEN NOT MATCHED THEN
INSERT(name) Values(tv.name)
Output tv.levelValueId ,inserted.LevelValueid INTO
Mg_TableA;
/********************************ACTUAL MIGRATION FOR MASTER TABLE***************************************************************/
/********************************ACTUAL MIGRATION FOR CHILD TABLE***************************************************************/
Insert into TableB (name,LevelValueID)
Select A.name,B.NewValueId From sample.dbo.TableB A
Inner join Mg_TableA B on A.LevelValueID = B.LevelValueId
/********************************ACTUAL MIGRATION FOR CHILD TABLE***************************************************************/
/********************************TEST THE VALUES***************************************************************/

Different ways to Transfer data from one database to another database

Hi all,
What are the ways to transfer data from one database to another database. With the following options, i Can transfer data as far as i know. Please
correct me if i am wrong or tell me if there is any other options are available.
1) Create database link/connection string and using this string and COPY command, we can transfer data.
2) By using Export and Import utilities.
I told first one to my interviewer, he told, its strange, by using, COPY command also can we transfer data ? As far as i know, we can transfer data. Am i right ?
Thanks in advance,
Pal

transfer data from one database to another database.You mean store the data of one to another?
1) Create database link/connection string and using this string and COPY command, we can transfer data.every SELECT on a DB-link is transfering data. And you can have all kind of transfers and store on the e.g CTAS of materialized views or.... the SQL*PLUS COPY :
The COPY command is not being enhanced to handle datatypes or features introduced with, or after Oracle8i. The COPY command is likely to be made obsolete in a future release.
But there are many others. Check for ORACLE Streams, and the "COPY" your interviewer was mentioning is about the operating file system COPY right? That's transportable tablespaces.

Hi
U can use a <a href="http://help.sap.com/saphelp_nw04s/helpdata/en/9c/d736b880c34f76b507bac7751a0474/frameset.htm">DBCON (Database Connection) tool</a>.
Here you should call another database and write SQL native code in order to transfer/read the data.

How to copy data from one table to another (in other database)

Hi. I would like to copy all rows from one table to another (and not use BC4J). Tables can be in various databases. I have already 2 connections and I am able to browse source table using
ResultSet rset = stmt.executeQuery("select ...");
But I would not like to create special insert statement for every row . There will be problems with date formats etc and it will be slow. Can I use retrieved ResultSet somehow ? Maybe with method insertRow, but how, if ResultSet is based on select statement and want to insert into target table? Please point me in the right direction. Thanks.

No tools please, it must be common solution. We suceeded in converting our BC4J aplication to PostgreSQL, the MSSQL will be next. So we want to write simple aplication, which could transfer data from our tables between these 3 servers.

How to migrate targets from one oem to another oem

Hi ,
we have two gridcontrols as follows
https://oemgrid1:7799/em/console
https://oemcnt:7799/em/console
we have to move the 10 targets from one OEM ( https://oemgrid1:7799/em/console) to another OEM ( https://oemcnt:7799/em/console ) inclusing data ...
how to migrate , any idea ?

A) Assuming that both the EM are of same version, then you cannt migrate data and targets from one em to another.
B) Assuming that both the EM are of different versions like EM1 10.2.0.5 and EM2 12.1.0.2 then also you cannt migrate data and targets from one em to another. In this case you still have the option to undergo the EM Upgrade process which will automate the historical data and target migration.
