Diference between RAC and Grid

I have 9i r2 RAC.
What is the diference between 10G RAC and 10g Grid?
What are my options to migrate?
What are the advantages and disadvantages between migrating to 10g RAC or migrating to 10g Grid?

A lot of the differences are cosmetic. Parallel server in 8i became RAC in 9i became Grid in 10g. There is no such thing as 9i Parallel Server, nor is there such a thing as 10g RAC, at least from a marketing standpoint. Once you understand that, the major differences are incremental-- 10g is probably more maintainable and easier to set up than 9i, 10g is probably more scalable as well.
Migration is just a database upgrade. The upgrade guide will enumerate your options.

RAC and Grid Computing

Hi,
I am trying to understand the connection between RAC and Grid Computing.
In RAC, we can have multiple instance of the same physical database and if all these instances are running on n* separate machines then we have n+ set of processes to take care of computation.
Isn't this summarise the Grid computing as well or is it something entirely different. Please share.
Thanks in Advance

Hi,
Billy already answered well.
Litte Note:
Timeline of Oracle Databases:
1992: Oracle version 7 appeared with support for referential integrity, stored procedures and triggers.
1997: Oracle Corporation released version 8, which supported object-oriented development and multimedia applications.
1999: The release of Oracle8i aimed to provide a database inter-operating better with the Internet (the i in the name stands for "Internet"). The Oracle8i database incorporated a native Java virtual machine (Oracle JVM, aka "Aurora").
2001: Oracle9i went into release with 400 new features, including the ability to read and write XML documents. 9i also provided an option for Oracle RAC, or "Real Application Clusters", a computer-cluster database, as a replacement for the Oracle Parallel Server (OPS) option.
2003: Oracle Corporation released Oracle Database 10g, which supported regular expressions. (The g stands for "grid"; emphasizing a marketing thrust of presenting 10g as "grid computing ready".)
2005: Oracle Database 10.2.0.1—aka Oracle Database 10g Release 2 (10gR2)—appeared.
2007: Oracle Corporation released Oracle Database 11g for Linux and for Microsoft Windows.
Future (*Just a guess*): Oracle Database will release version 12c. (The c stands for "cloud"; emphasizing a marketing thrust of presenting 12c as "Cloud Computing ready".)
Oracle has released products with "C" of the "Cloud" (e.g Oracle Enterprise Manager 12c)

Diference between STO and Shipment order?

Hi All ,
There are two plants , one is manufacturing and other is sales . In sales plant sales order is created and after MRP run Purchase requisition is created(for getting materisl from production plant) . In me59 we convert this Preq to shipment order.
1)Can oyu please tell me whant is diference between STO and shipment order?
2) Can you tell me what is the configuration to avoid creation of shipment order and system will only create the STO from Preq after executing Me59?
Thanks
Rohit Chavan

Hi Chavan,
Starting with "Shipmnt Order" definition => (from SAP Help):
   An order to a transportation service provider to ship goods from a shipper to a single consignee with agreed terms and conditions. The corresponding confirmation from the transportation service provider is also part of the business object.
   You can use this business object to subcontract the transportation of goods from a shipper to a single consignee if you cannot fulfill a shipment request yourself or if you regularly subcontract transportation services.
   You can also use this business object in the process of transportation service provider selection and tendering. The aim of both processes is to assign a suitable transportation service provider (TSP) to a shipment order.
http://help.sap.com/saphelp_tm60/helpdata/en/66/dda98bb6b64c30b925f031bb0a2023/content.htm
STO is just Stock Transport Order => functionality to move stock from one plant to another plant in two steps( inclidung GI in the sending plant and GR in the receiving plant).
Usuall documnt flow in the STO process => PO(UB or NB order type), delivery, GI -> GR (done via migo for example).
I believe that you can avoid cration of the Shipmnt order via correct selection on ME59 screen. Just something what is characteristic for STO and not for Shipmnt Orders.
Best Regadrs,
Tomek.

New implementation - Client having issues with RAC and Grid on Windows

Client is starting a new implmenetation on Windows 2008 R1, Oracle 11.1.0.7. They have a 3 node RAC and Grid Control. They are having a number of issues and support is working through those issues. They are asking if there are clients on RAC and Grid on Windows. The Wiki shows a few customers on Windows, but was hoping to get some feedback. Tks.

There are lots of customer applications that are based on Windows RAC. And as mentioned above, it is very well supported by Oracle.
However, because of the security vulnerabilities of Windows, I've observed that most of the financial institutions and listed companies opt for unix based servers for all high profile applications and run only low to medium risk application on Windows.
Regarding maintanence issues, I guess it's going to be pretty much the same; there shall always be lots of bugs, lots of patches and updates just like an yother software; doesn't really matter if you are on Unix or Windows systems. As long as you purchase support, it's all good.
It's pretty much same concern regarding Grid Control on windows.
Cheers.

Diference between DATA: and TYPES: on internal tables

Hi people,
Can somebody help me. I wanna know whats the diference between DATA: and TYPES: on internal tables
and whitch has the best performance, here is a eg:
DATA: BEGIN OF ti_sbook occurs 0,
          carrid   LIKE sbook-carrid,
          fldate   LIKE sbook-fldate,
          customid LIKE sbook-customid,
          loccuram LIKE sbook-loccuram,
       END OF ti_sbook.
AND
TYPES: BEGIN OF ti_sbook ,
          carrid   LIKE sbook-carrid,
          fldate   LIKE sbook-fldate,
          customid LIKE sbook-customid,
          loccuram LIKE sbook-loccuram,
       END OF ti_sbook.
DATA: gw_sbook       TYPE TABLE OF ti_sbook,
gs_sbook       TYPE ti_sbook.
witch of both types is better?
thanks.

Hi Marcelo,
For compatibility matters is better to create internal tables with a work area separately. So yes it's better to use types. When you work with Object Oriented coding you will need to use internal tables defined with types. Also when defining tables with types is the new way of coding, the another coding is getting obsolete defined by SAP. That's why when working in ABAP with OO (Object Oriented) code you'll have to define tables with types and not the other way.
Hope it helps.

Doubt about diference between SAPconsole and SAPmobile

Hello,
     I have been many doubts about diference between sapconsole and sapmobile, if anyone could help me I appreciate.
1) I have ECC6 instaled, the SAP Mobile is compatible with ECC6 or I need of Netweaver Instaled ?
2) If Possible to Install Sap Mobile in ECC6 , I have to Buy a license of sap mobile ?
3) in any product instaled Windows CE have possible to install sap mobile ?
4) In sap console what is the requirement for to do this configuration?
I Anybody to know about this informations please explain for me ?
Thanks

My apology,
    The Basic Diference beteween SAPConsole and SAPMobile is :
SAPConsole ==>
1 ) Don' t need a new Hardaware for to configurate
2 ) Only need a Machine with the IIS service installed
3 ) The SAPGui CD content the SAPCOnsole.exe for configuration
4 ) The equipment like Pocket and datacolletor has been to configurated in a Network( but if to have a entrance in the SAPGUi indicate a SAProuter in another factory is possible to have acesses.. ) is a mandatory. Cause the SAPCOnsle folow the SAPGUI entrances and need a LAN or a WAN configurated.
Advantage
simple to congurated and chip.
Easy to create to new window cause the SAPConsole only plubish this window in Browser.
Disadvantage
Need a lincense for each Poket or Datacolletor, wherever the equipment you will use.
Doesn't have a Database using through Browser (IE6 or IE7) this way , during the processes lost network you go to lost the information not saved.
SAPMobile
1 ) Need the a good Machine with a instance of SAP configurate
2 ) Have to found the EXE in the MarketPlace
3 ) is not publish, and yes a client with the database configurate in equipment
4 ) The equipment like Pocket and datacolletor has been to configurated in a Network
Advantage
Need only one SAP License, doesn't metter how many equipment in use you have.
As the SAPMobile has a Database in the client , if you lost the network it goes to save in the local database and when the network come back , it will to synchronize. This way you don't need to work online every moment, you get to synchronize after.
Disadvantage
You profit in license is your lost in the Machine cause the price of Machine is expensive.
is configurate only in windows Mobile.
The window only can be create for a Developement and not in the SAP, have been created in windows Mobile.
A tip, the both is good but you can do a simple mathematics.
In the SAPConsole how much money you go to spend is the least of the Machine s Price.
If yes confurate the SAPConsole , if not configurate the SAPMobile

Need to understand basics of Oracle RAC and Grid technology, for training

I need to understand Oracle RAC and Grid infrastructure, from a manager's / training perspective.
I see links here and here, so a couple questions:
- what's the basic difference from a layman's (e.g., a manager's) perspective ?
- What training options are available for a generic 11g DBA to learn this new technology ? I've seen this course from an Oracle partner ("Course:Oracle 11g: RAC and Grid Infrastructure Administration Accelerated Release 2"), for a boat load of money, for 5 days I think. So we're looking for something a little more reasonable (and accessible), e.g., books, online, etc.

For a very basic definition, RAC is technology that is used by the database and GI is the infrastructure that makes RAC work. In a forum reply, that's probably all what can be said about both. For a very lengthy answer, you should read the links that you have quoted.
For #2, the course that you are looking at is called Accelerated as it combines two courses in a single week training-RAC(4) and GI(3). So it's a 7 day curriculum that one would be doing in a 5 day course and that should justify its cost. But let me say, it's a really really good course. But on the other side, it can be quite overwhelming for someone who doesn't know about these technologies already. So I shall suggest that you send your team to each course individually and probably after doing some homework . They can start reading the following books,
Pro Oracle Database 11g RAC on Linux

And this doc link,

Diference between choice and message choice

Hi
I'm testing UIX. What is the diference between choice and message choice? When I can use this components?
Thanks
Liceth

The messageChoice control is a combination of the choice and messageLayout controls. You can read about all the components in JDeveloper's help.
The messageLayout control lays out a prompt, indexed children, end child, tip, and inline message (error message that displays below the choice, for example). Typically, the only indexed child of this bean will be a form element of some sort, but as many children as necessary can be added.
The prompt can have an icon associated with the type of message. The bean's destination is attached to the icon to link to further information. It is also possible to indicate that user input is required.
Clients can also add an "end" named child which will be rendered after the indexed children.
To lay out multiple messageLayout beans the messageComponentLayout bean should be used. When messageLayout beans are placed inside a tableLayout or labeledFieldLayout the prompts will line up.

Problems distinguish between OEM and GRID in documentation

Hi all,
I know, probably mine is an annoying question, but I really find difficult to distinguish the topis related to OEM and GRID. I have to configure the OEM dbconsole for a cluster, forcing a virtual IP, but I go lost in documentation (metalink too) because is quite impossible to have a clear and definitive guide to OEM NO GRID.
Is anyone able to point me to an exhaustive documentation??
Any help will be appreciated.
thank you very much

You are right, there's no specific DBConsole documentation. Standalone DBConsole is installed and configured by utility 'emca'. On metalink there's a comprehensive description of this utility,including for clustered environments.

Diference between close() and dispose()

in Java Swings we had two methods to close a JFrame, i.e frame.dispose() and frame.hide() / or frame.setVisible(false).
But in FX, we have a single methos to close the stage which is : Stage.close() and it is equivalent to hide().
So does that mean, on calling stage.close(), the memory and the resources allocated to the stage remain intact and the stage is only vanished from the screen?
Does that further imply, FX doesnt have any method to comple 'dispose' of the stage as in swings?
please reply
Edited by: 949779 on Jul 30, 2012 6:17 AM

The docs donot say anything about the resource management done by Stages. Comparing it with Swing is useless since they're completely different.
The reason for dispose() in Swing was that even when your code does not refer to a JFrame anymore, there are still native resources which refer to the JFrame which will keep it from being garbage collected. Dispose() releases those resources.
In JavaFX the distinction between close and dispose is probably no longer needed because using weak refs they can track when the Stage is no longer referenced anymore and then release all resources associated with it (if it works that way at all).
So, close() would 'hide' the Stage, and when it gets garbage collected an automatic 'dispose' occurs. If Stages needed any further special treatment I would expect a mention in the docs.

Diference between Consolidate and consolidate all with data

I would like to get clarified on the differences between "Consolidate" and "Consolidate All" option in HFM while performing a consolidation.

Consolidate finds only the part of the data that is impacted by changes and performs all calculation, translation and consolidation rules for only that part of data.
Consolidate All on the other hand calculates everything even if there are no underlying changes
Consolidate All With Data performs as the Consolidate All it skips entities that have no data inputted though

Oo diference between delpi and Java.

I want to know what the oo differences are between java and delphi. I always thought delphi was a old not very advanced language, but I found out it supports encapsulation, inheritance, polymorfism and even interfaces.

What OO differences are you concerned about, specifically?
I've been away from Pascal since the '80s, so I don't know much about Delphi.
Regardless, I would look into the following OO feature comparison (off the top of my head):
- Multiple inheritance
- Inner classes
- Interfaces
- Name Spaces
- Type Safety
- Garbage Collection / Memory Management
- Reflection
