I want copy some tables from one database to another. Which of following is the fastest way:
- INSERT /*+APPEND*/ via database link
- Transportable Tablespaces
- datapump IMP/EXP (I supposed it's the slowest way)
I have the task to migrate the total databases(Exact copy to be moved to another server).The current server is going for format.After I did the following steps I am getting the tablespaces(databases)-4 sizes same ,but I am facing issue like some default tablespaces i.e temp,system are not matching.
temp tablespace
***************
current server - 4.0(approximately)
Migrating server - 160 MB
System tablespace
*****************
current server - 580 MB
Migrating server - 220 MB
Also I checked the tables are also matching for the 4 databases.Also Provide the solution or method which is correct.
steps done for migrating(By me)

EXPORTING DATA USING DATAPUMP
*********************************
1 From command prompt MKDIR 'c:oraclexeapp mp';
2 From SQL prompt conn system/kotak;
3 create or replace directory dmpdir as 'c:oraclexeapp mp';
4 grant read,write on directory dmpdir to kotak;
5 From command prompt
expdp system/kotak@xe full=Y directory=dmpdir dumpfile=xe.dmp logfile=expdpxe.log;
IMPORTING DATA USING DATAPUMP
*****************************
in another server machine
1 From SQL prompt conn system/kotak;
2 create or replace directory dmpdir as 'c:oraclexeapp mp';
3 grant read,write on directory dmpdir to kotak;
4 From command prompt set ORACLE_SID=xe;
5 impdp system/kotak@xe full=Y directory=dmpdir dumpfile=xe.dmp logfile=impdpxe.log;
IN OUR PROCESS we created the below tablespaces and user before IMPORTING created 4 tablespaces
1. kotak
2. kotakdb
3. wired_data
4. ferrari
Created Users which are there in 219 server
1. KOTAK
2. KOTAKDB
3. FC_80
4. DEMOINTERNETBANK
5. DEMOINTERNETBANKDB
6. CREDITCARD
I want to compare the table contents across the two different databases , one is on netezza and other is on Exadata.
View 2 Replies View RelatedWe want to replicate the data between the databases.We have 4 databases in a network.If there will be any change in database 1,e.g. updation in any table,it should automatically replicate on other 3 databases.or user will change something in database 2 ,it should replicate on other 3 databases and vice versa. All 4 databases have same schema and same configuration.

I have one primary database and one physical standby database on my data guard environment.
Now i want one more physical standby database in my data guard environment, meaning i want 2 physical standby. since this is a production environment, i need to take great care. However, downtime will be mandatory.

oracle 11.2.0.3 I have insert only tables that receive srecords from multiple processes at a rate of about 200/second. Each transaction can have up to 100 records. I have another set of processes that queries this table for the latest data. These processes run anywhere from once a minute to once an hour. Processes do not get all of the data. They get data based on a type field.
Both of these are from java middle tiers. The process that queries data (The subscriber) does so at the request of many remote servers (there will be vast numbers). I am not allowed to expose these downstream databases to the internet (they are not oracle DBs anyway) so I cannot use streams or golden gate
So basicallyInsert Process: multiple sessions that combined insert records up to 200/second. There will be between 1-100 records per commit.
Query Process: Downtream process makes a request to my middle tier. This middle tier runs a query to get the latest data and passes it back. This design is set and I cannot change it.
1. right now we capture the insert time of the record. However, at this rate of inserts some processes will commit faster than others. So I cant use a 'greater than my insert time' query.
2. streams/golden gate won't work. can't register these DBs.
3. don't want to serialize my inserts because since I am not sure I can keep up with the insert rate. I don't even know what the specs will be for the production hardware. I have to actually deliver this before its decided. So I am being conservative.
4. I really want to avoid updates on this table if possible. In part due to my limited ability to test.
5. due to the number of downstream processes it is possible that it will request data and for some reason fail to insert the data locally. So the downstream application will keep track of the latest data it received. This means that a subscriber may need to request the same data again.
Is there a way to set up change data capture with multiple subscribers to handle this? if my subscribers are just queries? All the queries come from the same servers(there will be several, but all the same thing). If so, when I performance test this are there any wait issues I should keep an eye on?
i could copy data from tableA to tableB with the scenario below
1) Currently we have no unique key / primary key defined on both of this tables, due to the nature of data, so insert/update will not work
2) We cant truncate/insert as user will be accessing this tables when the copying process takes place, so we dont want to end up having a scenario where the table does not contain data at a certain time
Will materialize view full refresh work in refreshing a table so we could avoid the problem faced in point 1 & 2.
I have two tables namely PERSON and WIFE. I want to make WIFE's data available in PERSON table while keeping entries of WIFE maintained and at the same time adding some the values of PERSON against the data of wife.
PERSON Table
PK NAME ADDRESS IS_MARRIED
1 John ab city Y
2 Varvatos cd town N
3 Smith ef town Y
4 Henry gh city Y
5 Lynda gh city Y
WIFE table
PK PERSON_ID (FK) NAME
1 1 Alice
2 3 Rosy
3 4 Lynda
Now i want to copy data of WIFE table into PERSON table like this PERSON table
PK NAME ADDRESS IS_MARRIED
1 John ab city Y
2 Varvatos cd town N
3 Smith ef town Y
4 Henry gh city Y
5 Lynda gh city Y
6 Alice ab city Y
7 Rosy ef town Y
As in the given example you might have noticed that ADDRESS of wife is same as of her spouse and same goes for IS_MARRIED column. Moreover, the PK is also not duplicated. How to go about this?
Another important factor is Lynda already exits in PERSON table, therefore, i certainly don't want to duplicate her entry.

I am developing an application for making the travel entries for my organization employees.
For that purpose I have 3 datablocks named:
1) Travel header
2) Employee Detail
3) Travel Detail
which are interlinked through constraints.
I want to give 2 options ie. either single booking entry or Group booking entry.
The form is working properly for single booking entry. But when I want to make a group booking wherein many employees have to travel between common locations I have to fill all the travel details again for all employees. I want to avoid that since it wont give a feasibility for this application. I can copy the travel details I have entered for the 1st employee. I am uploading the form layout.

Backup file should be save in pre-defined location then user will use a form which I developed for loading data into head office there are two different buttons in this form;
First is used to load data, actually first I load data in a temporary user which creates whenever user will press this button. Second is used to copy data in application user but first it checks if data exists then update otherwise insert.
