Mechanism between DB server and application server

Hi,
Currently I have ebs R12.1.3 installed and DB is under upgrade from 11.1.0.7 to 11.2.0.2.
While upgrading the database server, I got a question how the application server finds database server.
The question might sound a bit foolish, but that's how it is. :)
For example, when DB is upgraded, upgrade, configurations, and post activities are explained on DB side in documents.
But then, how does the application find database server after new DB is installed?
Does it work based on the updated listener file only...?
Or, is there any configuration that needs to be done on application server side as well after the DB is upgraded?
Can anyone help with my questions...?
Thanks,

What is the diffrence between sap events and application events

Hi all,
what is the diffrence between sap events and application events.Can any one tell me with examples.
regards,

Hi,
Look at this,
<b>System Events (Default)</b>
The event is passed to the application server, but does not trigger the PAI. If you have registered an event handler method in your ABAP program for the event (using the SET HANDLER statement), this method is executed on the application server.
Within the event handler method, you can use the static method SET_NEW_OK_CODE of the global class CL_GUI_CFW to set a function code and trigger the PAI event yourself. After the PAI has been processed, the PBO event of the next screen is triggered.
The advantage of using this technique is that the event handler method is executed automatically and there are no conflicts with the automatic input checks associated with the screen. The disadvantage is that the contents of the screen fields are not transported to the program, which means that obsolete values could appear on the next screen. You can work around this by using the SET_NEW_OK_CODE method to trigger field transport and the PAI event after the event handler has finished.
<b>Application Events</b>
The event is passed to the application server, and triggers the PAI. The function code that you pass contains an internal identifier. You do not have to evaluate this in your ABAP program. Instead, if you want to handle the event, you must include a method call in a PAI dialog module for the static method DISPATCH of the global class CL_GUI_CFW. If you have defined an event handler method in your ABAP program for the event (using the SET HANDLER statement), the DISPATCH method calls it. After the event handler has been processed, control returns to the PAI event after the DISPATCH statement and PAI processing continues.
The advantage of this is that you can specify yourself the point at which the event is handled, and the contents of the screen fields are transported to the application server beforehand. The disadvantage is that this kind of event handling can lead to conflicts with the automatic input checks on the screen, causing events to be lost.
Hope u understood.
Thanks&Regards,

SSRS 2012 ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application

I have a SSRS installation, I have deployed my connections to, but they fail with title message. The drivers and ODBC on the box are setup and work fine with 32 bit ODBC conn manager.
When I run or configure my connections on the site, via the browser, I get errors connecting.
I tried to find which app pool http://server/ReportServer application used, but I am not finding that, so my first ?
How do I find in IIS what app pool SSRS application is using?
I have 2008 server, running SQL 2012 V.S. 2010 and I think I need to enable my app pool to use 32 bit, but cannot figure out which one it uses? I see default set to 32 bit = true, which I thought would be it.
Can I set my SSRS project to use x86, platform? Like I did with SSIS?
If so, how? SSRS and SQL 2012 somewhat new for me. Thanks

Hi DCady,
To manage a data source that connects to a 32-bit driver under 64-bit platform, we use C:\Windows\SysWOW64\odbcad32.exe. To manage a data source that connects to a 64-bit driver, we use C:\Windows\System32\odbcad32.exe.
Generally, if we use the 64-bit odbcad32.exe (C:\Windows\System32\odbcad32.exe) to configure or remove a DSN that connects to a 32-bit driver, for example, Driver do Microsoft Access (*.mdb), we will receive the following error message:
The specified DSN contains an architecture mismatch between the Driver and Application
To resolve this error, we need to use the 32-bit odbcad32.exe (C:\Windows\SysWOW64\odbacad32.exe) to configure or remove the DSN.
Besides, please make sure there are no DSN using the same name in both 64-bit and 32-bit ODBC Data Source Administrator.

Architecture mismatch between ODBC driver and application

Hi,
I have Windows 2008 server R2 OS which is 64 bit OS. I have created an SQL Server ODBC connections for my CMC database. I am trying to install Crystal Reports Server 2008 V1 SP3 but I am getting this "architecture mismatch between ODBC driver and application" error while choosing the ODBC datasource for CMS.
I thought CRS 2008 version would easly be installed on Windows 2008 server as it mentioned on the installation guide.
How do I resolve this issue?

Moved to BOE Admin forum.
CRS 2008 is a 32 bit app so all attachments, Printers, DB clients, etc. must all be 32 bit or support 32 bit applications.
Use the 32 ODBC administrator in \windows\syswow64 folder.
Thank you
Don

Communication between a driver and application.

Communication between a driver and application.
I am writing a driver for a PCI card. I have found very good examples of how the driver should be build.
Where do I find the information about how the user mode application should be talking the driver.
So If you have any idea that will help me, please let me know.

Hi,Sir
This for your reference.
It will create pci adapter device node at /devices .
You can use AP function call ioctl to Communicate with your device driver.
static int
xxattach(dev_info_t *dip, ddi_attach_cmd_t cmd)
int instance = ddi_get_instance(dip);
switch (cmd) {
case DDI_ATTACH:
allocate a state structure and initialize it.
map the device�s registers.
add the device driver�s interrupt handler(s).
initialize any mutexes and condition variables.
create power manageable components.
* Create the device�s minor node. Note that the node_type
* argument is set to DDI_NT_TAPE.
if (ddi_create_minor_node(dip, "minor_name", S_IFCHR,
instance, DDI_NT_TAPE, 0) == DDI_FAILURE) {
free resources allocated so far.
/* Remove any previously allocated minor nodes */
ddi_remove_minor_node(dip, NULL);
return (DDI_FAILURE);
* Create driver properties like "Size." Use "Size"
* instead of "size" to ensure the property works
* for large bytecounts.
xsp->Size = size of device in bytes;
maj_number = ddi_driver_major(dip);
if (ddi_prop_update_int64(makedevice(maj_number, instance),
dip, "Size", xsp->Size) != DDI_PROP_SUCCESS) {
cmn_err(CE_CONT, "%s: cannot create Size property\n",
ddi_get_name(dip));

return (DDI_FAILURE);

Difference between component configuration and application configuration in webdynpro

what is the difference between component configuration and application configuration in webdynpro?

Hi Rohit,
With the component configuration, you can control the behavior of each individual component within a Web Dynpro application or the user interface of individual views. For each component, several records of configuration data can be created.
Using the application configuration, it is now possible to assign the configuration required in the current application to all the components used.
In short : Component Config belongs to WDP Component and Appl'n Config. belongs to WDP Appl'n.
Check this document for more information.

Difference Between central instance And application instance

Hi every body can any one tell me that
what is the difference between Central instance and Application instance.
If i am using 4.7 ee with orcale data base.

Check these links
http://oreilly.com/catalog/sapadm/chapter/ch01.html
Basically these terms comes when you are working on live servers where all the users log into to do their daily work.
We says when we want to distribute the workload on servers we requires central instance and application servers.
Normally it is not known to common users where they are logging into...but they can login directly usign the specific Instance details of servers.
Please see this also

Difference between Business message and application message

Hi B2B Gurus,
Can you please explain the difference between Business message and application message?
Regards,
Praveen

Hi Praveen,
Business message status reports identify business message instance details for a document protocol. These details include the sending and receiving trading partners, the agreement name, the business action, the business message ID, the status, the exchange protocol and document protocol, and message details.
Application Message Reports provide information related to the SOA Composite—the name, version, and so on, if a back-end composite application sent or received the message.

Confussing between Database User and Application User in Discoverer

Hi All,
I am new to Discoverer.
Please let me know the difference between Database User and Application User in Discoverer Administrator as well as in Discoverer Desktop Editions.
1) While I am trying to connect to Discoverer Desktop, I am unable to connect to it with Apps Database User.
2) Where the Discoverer compenent will be installed and what the configuration settings need to done work on it.
Please let me know the answers soon.
Thanks in Advance.

Hello
I think a database user should pretty much be self explanatory - this is a user account that exists in the database. This account is created by your Database Administrator (DBA).
The second kind of user that Discoverer understands is a user that exists inside Oracle E-Business Suite (EBS), formerly known as Oracle Applications, hence an application user. This user account gets created by the EBS system administrator.
Now, just because you're using EBS, it does not automatically follow that users will be application users. Let me explain.
Discoverer can be installed in one of two modes, standard mode and Applications mode.
The vast majority of organizations use standard mode which means they allow database users to access the system.
The only time that you will need an applications account is under the following two rules:
1. Your organization is using E-Business Suite, AND
2. Your Discoverer administrator has installed Discoverer in Applications mode.
Applicatons mode does not happen automatically, even if you have EBS, and you cannot install that mode by accident. You have to tell Discoverer that it is operating in that mode, provide some additional EBS account information, make security assignments and set users have to deliberately tell Discoverer they want to connect using an applications account.
May I suggest you get hold of a copy of the Oracle Discoverer 10g Handbook that I wrote. That book explains in detail the differences between the modes. I also have a free white paper on my website that describes how to install Discoverer into Applications mode.
I hope this helps
Best wishes

Difference between Information Field and Application Field

Hi,
Can anyone tell me the difference between information field and application field in ucm?
Thanks

Information fields are metadata fields that describe the content - by default they will appear on the interface and be searchable etc.
Application fields are a special sort of meta field normally used behind the scenes to help with the logic of forms/templates. Application fields do not normally appear on the interface and are not searchable.
More simply put if you just want to add content metadata just use Information Fields

Differences Between Grid Control and Application Server Console

Hi,
I have come across a situation where a customer has an OC4J container and has deplyed several applications in this container. When they access Application Server Control Console thay can stop and start these applications individually.
However, the customer cannot monitor the status/state of these applications from withing Grid Control. We can see that the OC4J container is either up or down and will be alerted for the change of status. However, if a single application within the container is down they will not be alerted.
We are using GC 10.2.0.5, iAS 10.1.2.2. Is there a way around this, or dies the Application Server Console have a little extra functionalitly in it compared to Grid Control?
Tim.

Hi,
On your grid control, create a new Notification rule and select "Web Application" from the target drop down and then select your application then in availability tab, select up and down for which you want to receive notification.
