Replication :: Update Database On Daily Basis?
Feb 7, 2013
There are 2 databases, database A and database B. Database A is Oracle 11.2.0.2 which runs on linux and Database B is Oracle 11.2.0.2 which runs on windows xp machine. In database A, there are 100's of tables which are being updated every 10 minutes or 15 minutes. For reporting purpose, the developer wants to run report for the tables. But since database A is being updated every now and then, generating reports takes almost 15 to 20 minutes. So the reports can be generated in Database B. Once in a day the database B should have the updated data from database A so that the reports can be generated in database B with less time. What could be the best solution for the database B to have the updated data on daily basis from database A in oracle?

DB 10.2.0.2
OS Window Server
I need to create a script to take the oracle database backup on daily basis for windows. Which method will be good exp imp, rman or coldbackup?
In our case mostly chance system will crash and we need to OS install first and then restore the oracle home and full database.

I need any good suggestion basically I have two different location
1- Factory
2- Head office
I have developed PRODUCTION module in factory and it is working fine and now I want to send data on daily basis to head office therefore I develop a form which will create backup in export format (.dmp) then user will send via email to head office.
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.

However, I need to refresh the group manually sometimes. Therefore, I cannot set the interval as sysdate+1.have tried setting the interval as follows. However, they are not correct
Quote:trunc(sysdate+1) +4/24
The next interval will show 9:25:20pm.
Quote:trunc(sysdate+1) + interval '4' hour
Incorrect syntax

There is a table called cd_details. It has fields like id, name, language, type etc.I need a form where the user can search the database on basis of language and name and then display the other details. I used a data block wizard and given a push_buttonwith (execute_query). But it's very clumsy. For eg, if the user presses next the next button then all the records are being displayed. Is there any way to do this thing in a better way?

2. I have FRA on standby database. The archivelogs from primary go to FRA on standby. I delete my archivelogs as follows:
DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-3';
Though the archivelogs are delete there are still empty folders of archivelogs that are not deleted. How to get rid of them automatically.

I have a scenario like, am having two databases DB1 and DB2 in different locations where I need to replicate some of the tables(around 10 to 15 tables) from DB1 to DB2(i.e. Whenever I update any table in DB1 it has to reflect in DB2.). Both DB1 and DB2 has the same database objects.
(DB version - Oracle 10g Release 10.2.0.4.0).
the steps how this can be done. Can it be done using Materialised View.

How I can maintain a replication scheme from a production database and a standby. I was watching the advanced replication methods of Oracle, but what I want is in the evening to run a process and modify the database incrementally and thus leave until the next night.
And the server I want to allocate to the standby database, also implements other processes, so my settings would be:
Production: Oracle Database 11g Linux 5.5
Standby: Windows 2003 Database 11g
Maybe that data is important, let me make clear that what I want is that the database is updated incrementally.

I have a table MYTABLE in database mydb1 duplicated via materialized view and materialized view log and refresh_snapshot commands to a MYTABLE on mydb2 database.
I like to duplicate this table MYTABLE to a third database mydb2, using the same method (materialized view and refresh_snapshot command).
Is it possible ? What's hapend to the materialized view log where I launch a refresh_snapshots on mydb2 ? How is this materialized view log truncated ?

1)first block contain 3 items from_date and to_date(nondatabase)and find button
2)second block contains 3 items segment1, quantity and payment_terms
when i enter 2 dates and click on find button 2nd window open. segment1 and quantity between this 2 dates comes from base table like
select segment1,quantity
from po_lines_all pll, mtl_system_items mts
where pll.ITEM_ID=mts.INVENTORY_ITEM_ID
and creation_date between :FROM_DATE and :TO_DATE
and payment_terms should enter manually
3)2nd block contains summary button when i click on it, it save segment1, quantity, payment_terms and open new window which contain segment1 ,qty, payment_terms and when i click on summary button data comes from custom table which group clause means
suppose
item qty terms
a 2 2days
a 3 2days
b 3 3days
then on third form i shows like this
a 5 2days
b 3 3days
i done all this things but problem is that
suppose once data between 21-aug-2010 and 24-aug-2010 comes on second form , i enter payment_terms and save it. sumaary form also run properly but if another user enter date between 22-aug-2010 and 30-aug-2010 then it will shows data between 21-aug-2010 to 24-aug-2010 from custom table i.e with payment terms as earlier it save and from 25-aug-2010 to 30-aug-2010 it shows data from base table
like
item qty terms date
a 2 2days 21aug
a 3 2days 22aug

I have a clients who currently implementing an application that using Oracle 10g in 20 distributed location. Each location will have its own database server and locally managed. I plan to create a Disaster Recovery (DR) Centre for this client in centralised location. I plan to setup 20 Application Server but only one database server with 20 instances. My question, can the Dataguard manage the replication between 20 database (with single instances) and single database (with 20 instances? The reason we design such way is to reduce the license cost of Oracle.

We have three unix servers with four databases (10gR2) containing "HP Operation Management Unix" (OMU) server messages for monitoring purpose, and we now want to transfer these data to one new database on a new server for reporting purpose.
The message table in each OMU database keeps the message row until it is "Acknowledged" or for maximum fourteen days, then it is moved to an historic table where it stays for another three days. Keeping data for only seventeen days are a performance issue.The new "Reporting database" is intended to hold messages data for the last 90 days.
I wonder which method to use to move/replicate data against the databases? Materialized view using database link, with view on top of the MVs. How to keep rows longer than the master (source) table, avoiding deletion when master row is deleted
Oracle Streams, with local capture and remote apply. How will this influence on the master database performance. There are about 10000 new messages in each OMU database every day. Is it possible having four streams connections against the reporting database ?
Or should I simply use database triggers which fires after insert and update and applies changes to the reporting database using database links ?

We have Oracle Database Link linked to MySQL . We want to force executing remote statement that contains group by on the remote MySQL server and let MySQL do the aggregation instead of Oracle.
We tried also DRIVING_SITE but it doesn't work and the query that was sent to MySQL from Oracle DB Link didn't include GROUP BY and it looks like that the Group by was executed on the local Oracle.
Is there a way for force executing GROUP BY statements on remote DB instead of the local Oracle DB?
