How to replicate data ...help pl.. ?

Hi Friends,
I have two similar oracle databases one in my office and another in remote area connected through leased line, i want to replicate few tables from my office database onto remote database. Any new rows inserted in office tables it should be reflected in the remote tables immediately.
One method I know is using snapshots can be refreshed auto or manually whenever we want, can it be done using materialized views? if so how (briefly)? Is there any easy and new methods available in 9i ?
pl. help ...

Hi Joe
Thanks for immediate response.
Actually I am confused with Snapshots and materialized views... both are same or they are different? in your reply you mentioned 'materialized view (snapshot)'.
besides this one of my friends gave one solution just go thru it..
'Simply Create a DBLink between the databases and
create the materalized views on the required tables
and referesh them on commit on base table,u will get
the exact replica of the tables on the other database'
Is the same what you are talking about?
please..
If the remote database is read only, it can use materialized view (snapshot) to do so.
On your office db, create snapshot log on the tables you want to rep.
create materialized view log on <tables>
including new values;
on the remote db to create a snapshot and refresh every day:
create snapshot <snapshot_name>
REFRESH FAST NEXT SYSDATE + 1 <your querys>;

How to replicate data from MS SQL Server to Oracle

Hi,
Can someone please help me on how to replicate data from MS SQL Server to Oracle 8i database.

Dear,
I'm a student.
I do simple replication on Oracle 8.0.5 successfully. (one master site and one snapshot site). I only use the SQL*Plus and Schema Manager to do.
But when I do advance replication (multimaster replication) I meet many problem. So I don't get the result.
Do you show me the technology to do that ?
Thanks !

How to replicate data to hana server based on company code?

I have huge data in ECC system related to different company codes in multiple tables.
So while replicating data into hana system i want to pass company code as a parameter for selected tables.
Cos we have size constraints in HANA server.
So plz help to get the selected data.
You have my thanks in advance.

I am a little puzzled by your question. Is your requirement that if you change the parameter, only that data gets loaded into HANA and how often do you intend to change the "parameter"?
You can use IUUC_REPL_CONTENT to restrict the data coming in, for example you can define a where clause such that where BUKRS = 'XXXX' so only XXXX entries get replicated. I recommend to take a look at note 1733714 as this note has the guide which shows you how to define these transformations in the SLT server.
However if your goal is every time, you need to load different company codes, you will probably have to change the transformation, then reload the table dropping all the data you already have loaded. This essentially defeats the purpose of real time replication though.
One other alternative is create different views for different company codes in the source ECC, then use the views for replication. Take a look at this blog for information on how to replicate views.

How to replicate data in this manner

Hi everyone
I have a table in which there are 3524 records
and the value in a column is constant now i want to replicate the whole 3524 records but the primary key need to be incremented and the value in that constant column need to be changed
here is the str
id    product age item
1    15         10   2500
2     20        10   3000
3    25         10   4000here my age column is constant, now i want to replicate whole data and the age in that data need to be suppose 11
and the sequene should be 3525 to 7048

and i am short of timeSo what are you trying to tell us? No time to hire a consulant to do the work for you?
By the way thanks for the help
if you find a better solution like i have to do the whole thing 65 times then plz post..Sure we have:
using what carlovski already gave you
insert into [table_name] (id, product, age, item)
select id + 3524*age,
          product,
          10+age,
          item
from [table_name]
cross join (select level age
   from dual
   connect by level <=(65-10))Untested of cause since you didn't provide any create table statements.

How to replicate data between Oracle db and SQL server dbs in real time?

Hello,
Anyone has idea that what tool we can use to do data replication in real time between Oracle and SQL sever or Oracle and Sybase or Sql server and Sybase?
This is topic is brought by a project manager?
I only know Oracle to Oracle dbs by streams or GoldenGate.
Thanks
Jerry

Since GoldenGate's bread and butter was (and is) replicating data between heterogeneous data sources, and since Oracle has purchased GoldenGate, that would seem like a natural place to start.
Beyond that, it depends on the architecture you want and how you define "real time." Just about any ETL tool on the market, whether Oracle's ODI or OWB or any number of third party products (Informatica, DataStage, etc) can handle "trickle feeds" from various data sources to a database target of your choosing. Different tools will have different sorts of integration with the source database, many will require that a bunch of triggers are created to track changes on the source systems.
If you want Oracle to control the replication process (which doesn't really make sense if we're talking about replication from a non-Oracle database to another non-Oracle database), you can use the Oracle Transparent Gateway products to create database links from Oracle to the non-Oracle databases and query data on the source database periodically.

How to replicate data from one page to another page

I have a five page document that has the same information on all five pages but each page goes to a different person. I want to fill-in the first page and have the information replicate to the other four. Any suggestion?

Are you using LiveCycle (XML form)?
If so you need to set the binding for the fields to "Global".

Replicate Data with JApi

As I am new to this forum first:
"Hello to all !"
Does anybody has an idea, how to replicate data from one cube to another cube with the essbase java api ?
Problem:
I have a Webserver running and the webapplication is developed with jsp.
I want my users give the possibility to replicate data from a source cube to a target cube.
it would be great if i could integrate this into my jsp's.
(Essbase 7.1.0 )
thank you
Crashi

It depends on what you want to do.. The Java API gives you almost limitless possibilities.
For example, do you want the second cube in synch? You could use the API to update the outline on the fly as well.
Alternatively, do you want to export from the first cube and then load data with a load rule? You can do that too. It all depends on what you want to do given the limitations of the Java API.
Addressing the limitations of the API.. In 7x, the main items missing from the API was the ability to create load rules; none of the Essbase APIs currently support that. Further, you could not do anything with Essbase security/users/filters/etc nor could you create partitions. In 9.3.x, the ability to manipulate security/users/filters/etc was added.

Hi,
About Generic Extraction:
In Sometimes the Standard Extraction Does not Satisfy the Customers Needs that time We have to use Generic Extraction.
generic extraction is also classified in to three types
using
1. View
2.Infoset query
3.Function module.
Procedure:
-->Go to Tcode : RSo2,
-->There give the name of data source which you want to create like
transaction data source or master data attribue or Text data source.
-->enter
-->again in the next screen you need to give application like SD or MM
etc
-->in the same screen need to select table/view or infosetquery or
function module. these are different ways of creating data sources.
-->Give the name for the same like if u r creating data source on table
give the name of table.
-->click on Generic delta which will there in application tool bar and
fil the required columns in that screen like type of delta and all
-->continue and save
-->it will give all the fieds
-->enable the check boxes based on your requirement like selection or
hide or field only..
-->save

How to do basic LO extraction for SAP-R3-BW
1. Go to transaction code RSA3 and see if any data is available related to your DataSource. If data is there in RSA3 then go to transaction code LBWG (Delete Setup data) and delete the data by entering the application name.
2. Go to transaction SBIW --> Settings for Application Specific Datasource --> Logistics --> Managing extract structures --> Initialization --> Filling the Setup table --> Application specific setup of statistical data --> perform setup (relevant application)
3. In OLI*** (for example OLI7BW for Statistical setup for old documents : Orders) give the name of the run and execute. Now all the available records from R/3 will be loaded to setup tables.
4. Go to transaction RSA3 and check the data.
5. Go to transaction LBWE and make sure the update mode for the corresponding DataSource is serialized V3 update.
6. Go to BW system and create infopackage and under the update tab select the initialize delta process. And schedule the package. Now all the data available in the setup tables are now loaded into the data target.
7.Now for the delta records go to LBWE in R/3 and change the update mode for the corresponding DataSource to Direct/Queue delta. By doing this record will bypass SM13 and directly go to RSA7. Go to transaction code RSA7 there you can see green light # Once the new records are added immediately you can see the record in RSA7.
8.Go to BW system and create a new infopackage for delta loads. Double click on new infopackage. Under update tab you can see the delta update radio button.
9.Now you can go to your data target and see the delta record.
find your scenario and find what data sources do you need on R3 side and ensure they are active as well:
http://help.sap.com/saphelp_nw04/helpdata/en/37/5fb13cd0500255e10000000a114084/frameset.htm
find your scenario -> data sources -> go to R3 -> sbiw and activate required data source
replicate data sources in BW:
RSA1 -> source systems -> right click on your source system -> replicate
then activate your BC:
service.sap.com/bi -> BI Business Content -> General Information -> SAP BW Business Content - Activation
and execute infopackage (it should be delivered with BC)

recover the trail file col values to a SQL?GoldenGate "capture" (extract) parses the redo/archive logs and writes out trail data in a GG-specific, database independent format. The trail contains changed-data events: inserts, updates & deletes (and optionally DDL events.) The GG replicat reads this data and converts the data to SQL to be applied to the target.
The GG trail files are not the same as the data as originally seen in the redo logs (GG is not doing any type of log-shipping of redo logs). The actual data in the trail isn't really important for end-users; it's an implementation detail (much like you shouldn't care what Oracle's redo log format is). But you can use "logdump" to inspect the contents of this (binary) file... again, kind of like LogMiner can be used to inspect archive logs.
There are a number of (conceptual) analogies one can draw between Oracle redo logs & GG trail files. But they're not the same. Your questions are mostly internal implementation details that are not really important for understanding how GoldenGate works. Nonetheless, it is useful to become familiar with logdump for advanced troubleshooting.
Good luck,

How Does Time Machine Help If... iCal Data Lost?

Hi,
How does Time Machine help if, say, your iCal database gets messed up? Or, how does it help if you accidentally delete all your playlists from iTunes? I'd be interested to know.

That's a very good question (although probably better directed at Apple than us). Because Time Machine is new and Apple's in house programs handle data in different ways, there are a range of different means of recovering data for different applications. Not very user friendly and iCal is one of the least user friendly ones.
As an experiment, because I don't make much use of iCal and have no real idea how it works, I tried to find out how to restore its data. Starting with working with the application: nope, not TM aware at present. OK, where does it restore its data? Next step Spotlight where, as it happens, the obvious search "Calendars" brings up a folder in ~/Library labelled that with a whole lot of mysterious stuff in it. I'm pretty sure that restoring that folder would do the trick. No doubt, if you could figure out which Calendar belongs to what in the above folder you could restore a single calendar that was causing problems. Still, Apple's clearly got some work to do to make this more transparent. Roll on iCal4!
(By the way Mail also restores from within the program).

How to get up-to-date help menu in Illustrator CC?

Launching Illustrator Help in CC (International English) opens a PDF file, in which "What's new" tells me what is new in CS6 and CS5.
This does not seem right.
Is there something I can do to access the right help system for Illustrator CC?

Thanks, InfluenceJamie, but I was — at the time of posting — getting a PDF, not web help. And I don't know how to restore web help.
OK, after some more digging…
Somewhere in my history of using Illustrator I've managed to switch to accessing a local PDF instead of the web-based help system — which (in its latest incarnation) is what you have linked to.
The PDF file is called "illustrator_reference.pdf", and (on my Mac) it lives in Users > Shared > Documents > Adobe > PDF > pdf.
I've just found the latest version of it online here: http://helpx.adobe.com/pdf/illustrator_reference.pdf — which has let me update the file to CC.
To see if I can return to the web based system I have tried deleting the Adobe folder mentioned above. Attempting to access Illustrator Help after that produces a dialog box that tells me I must be connected to the internet (which, of course, I am).
Restoring the Adobe folder and deleting only the PDF folder within it (leaving the other folder, entitled "Help") produces the same dialog. So I've restored the PDF folder as well.
The upshot is that I now have up to date help in PDF format on my local drive but no idea how to revert to Web help.

Urgent help: how to create data source for Weblogic RMI driver

DataSource will internally do that for you (It will use RMI internaly) . You
dont have to worry about the details of using RMI driver. Thats what is a
DataSource is for.

Hi Pradeep
To create a connection pool you have to use a database driver not RMI
driver. So use a thin driver or the WebLogic jDriver for Oracle to setup
your connection pool. Once the connection pool is created you can create
a
DataSource and use this datasource to connect to the database.
The RMI driver can be used to get connections from the database via the
connection pool and in that case you dont need a datasource. Recommended
approach is to use a DataSource.
