Dependancy between Datasource and Application

Hi,
For our application we have created a new datasource in the JDBC Connector.
The datasource connects to MS SQL server.
I have observed that in NW the data sources are shown as application under the Deploy service. Hence I concluded that datasources are treated as applications by the server.
When the NW application server is started, sometimes the application is initialized before the data sources are started. Hence the initialization of the application fails.
Our application used Hibernate for persistence and the code for initialization of Hibernate resides in the Startup servlet. Since at the time of initialization of this servlet, the datasources are not started, the Hiberante initialization fails.
On the Deploy service, the application is shown as started but it does not work and throws "HibernateSession is null" exception whenever any functionality is invoked.
Currently as a work around we restart the application after the server is started but I am trying to find out a clean solution for this.
Is there any way to establish dependancies between applications while startup?
Is there any other way to ensure that the datasources start before the application starts?
Any inputs on this will be highly useful.
Thanks in advance,
Abhijit

BUT THE REAL PROBLEM is :-i want to connect that database..
i can't see my imported application or database..
Tell,, should i create any database or what should i
do..tell me detail step by step processFirst and foremost, you have a terminology problem. I will provide a working set of definitions. (But I fully expect to be corrected by some of the symantic specialists.)
- A database, in Oracle's terms, is a set of files.
- Inside of that database are a number of schemas, or collections of object definitions,
- Some of those objects are tables, which may contain data.
- The database is manipulated by an instance, or collection of processes and/or threads
- An application connects to the instance and requests specific manipulation.
In your case, you used the imp application, connecting to the XE database using the userid 'system' to import the schema objects from the schema 'jadi' to the schema 'yogesh'.
You could now use the application called SQLPlus to connect to the XE database - possibly using user "system" - to inspect the objects and object data imported in schema yogesh.
You might also be able to use the Application Express browser-based application to access the data in the various schemas. To do that we would need to explore other terminology such as "workspace"
I would encourage you to use the documentation at http://www.oracle.com/pls/xe102/homepage and perhaps search for the tutorial on the Products page (see the products link on the documentation page.)

Diff between content and application proposal

Hi
When i am assigning infosource to my standard datasource we have three options content,application proposal,others i know that for generic we use others but for standard business content we have content & application proposal options i think when we enhance the datasource we go for application proposal or if i am wrong plz correct me for standard datasources with no enhancement is it ok to go for content option plz confirm.
Regards,
Nikhil.

Hi Pradip,
Thanks for your reply but suprisingly i got an option while assigning for few datasources in SD where i had an option to choose between content and application proposal i had this doubt at this point of time as the system gave me two options and i had to choose b/w content and application propasal offcourse others option was greyed out i choose content option while assigning the infosource is that ok or i had to go with application proposal plz clarify.

What is the difference between apps and applications?

I have an application that I've been running on my older Mac. Now that I have a new MacBook Pro, I have to reinstall new software that is compatible. When I go to the vendor website I see an application I can download or a link to the Mac App Store. Is an application different than an app? When should you download them from a vendor website and when should you go to the app store? Do apps end up in the Launchpad and an application in your Applications folder? I can't seem to find information on what is the distinction. Are they actually two different things? Any help would be appreciated.

No difference between apps and applications. If you download the app from the Apple AppsStore you have better security and a conveninet place to have all your downloads. Nothing wrong with downloading from a trusted developer though.
EDIT: Yes they will either wind up in your Download folder as a .dmg you will have to double-click on to install, or most app store apps will install to your Applications folder.

Difference between Datasource and Connection Pool

Hi,
What is the major difference between Datasource and Connection Pool.
Both the Datasource with JNDI and Connectio Pool will serve the pool of connections. Then what is the difference.
regards,
Raj

A datasource is not implicitly a connection pool. You can configure that in the datasource properties. A connection pool is also not implicitly a datasource. You can create your own connection pool using the java.sql interfaces. A datasource just gives the ability to acquire the connections and access the database through JNDI. A connection pool just gives the ability to reuse a set of connections which are created/closed/controlled by the connection pool logic.

Auto create dependency between ViewController and ApplicationController

Hi all,
When you create a new ADF Mobile app, you will automatically create two projects: ViewController and ApplicationController.
I noticed that these are not related, that is, a dependency between these is not created in the ViewController.
I think you will need this dependency whenever you work with an on device database, in order to make a connection to that database.
At least, that is the way all the demos work, and I would probably do that myself as well.
So why not create the dependency by default.
Regards
Luc

We purposely did not create the dependency because it is not required by all applications. The main reason is for modularity. We have made the "ViewController" projects reusable modules and you can create a "Feature Archive" (akin to an ADF Library) as a deployment profile for these modules and thus an application can comprise of many features from different feature archives. It can be limiting if your app assumes there is a direct dependency on the AppController project because then you would not be able to create a feature archive without including that as well and it would conflict with other apps that already have that project and it's contents. If you are sure you don't want your project to be reused as a feature archive then it is ok to add the dependency.

Alert log: failed to establish dependency between database and diskgroup

Hi, I have a database 11.2.0 with ASM. When I startup an instance I see this error in alert log:
ERROR: failed to establish dependency between database SPBUFOR and diskgroup resource ora.SPBUFOR_FLASH.dg
SPBUFOR_FLASH is a diskgroup where a flash recovery area is located.
Database is opened cleanly but I need to know that everything works fine.
How can I resolve this issue ?

Bottleneck Between Oracle and Application Server

I am connecting Tomcat to Oracle thru thin JDBC driver. The link between tomcat & oracle is now found to be the bottleneck - too many JDBC calls that could be handled by the network. What are the possible solutions I can use now?
Some suggest to use Oracle Real Application Cluster (RAC) to scale the db tier. I am new to this. Would setting up RAC causes any change to my programs? Is it difficult to setup? Also, are there any other alternatives?

Web servers just handle static content, like HTML pages.
App servers have a few flavors.
A servlet/JSP engine has a Web server built into it, too. It can handle static content, like HTML pages, and also act as a container for servlets and JSPs. You can use JDBC with servlets and JSPs, of course.
A J2EE app server has a servlet/JSP engine and a Web server built into it. It can handle static content, like HTML pages and act as a container for servlets and JSPs. But it can also act as a container for EJBs - session, entity, and message EJBs. It has other services built in, like Java Messaging Service (queues), Java IDL (Corba), RMI, JNDI (naming services), XML parsers, JDBC (database access), and Java Transaction Service.
Enterprise Application Integration servers (EAI), like WebMethods, using XML messaging to tie multiple J2EE app servers together.

What patches to apply for reducing the dependency between portal and iAS

Hi,
I have migrated 11i applications from AIX to LINUX with 11.5.10.2 and db 10.2.0.3. Now the Apache server is not accepting any connections as portals are also implemented. So i think i need to apply patches, could any 1 plz tell me if u have applied similar patches to resolve it.
THANX

Hi Hussein,
Gud 2 c u back. I am refering to section 3 finishing tasks 2.b portal 3i in doc id 238276.1. Yes my source apps is portal implemented. And i refered to doc. ID 146469.1 where in it says install login server and portal patches. Do i need apply all those patches. And how can i determine if those patches are applied to source apps from migrated (target)db coz i dont have access to source machine rite now. thanx

Dependency between reports and subject area

Hi,
We are using OBIEE 10.1.3.3.
I would like to find out all the reports in a catalog which are dependent on a specific Subject Area.
Is there a way to quickly determine that ? Any suggestions are appreciated.
Thank you.

Hi
In the newer versions you can use an option in the catalog manager 'Create Report' which will extract Report Name, Subject area, etc....and puts in a csv file which will meet your purpose. I am not sure if this feature is available in x.3.3

New to Apple and Aperture-I am surprised at the lack of integration between Aperture and applications as iMovie.

Aperture slideshow is terrible in terms of entering any text on a photo. It appears that you have to export the photos from Aperture to the desktop to import the photos to iMovie to be able to add quite good text to individual photos. While I am new to the Apple system (I am quite knowledgable in Windows), I am surprised that iMovie cannot import an Album or a Project from Aperture. It does not appears possible to to copy and paste from Aperture to the project created in iMovie without exporting to the desktop. This seems like a step backwards.
Since I come from Windows I will be importing most of my photos into Lightroom3 and doing most of my work. Yet, there are features in Aperture that I like and will probably use both for the time being. I am using Aperture 3 and iLife11. New Macbook Pro

I read the manuals and watched the tutorials on the Apple web site as well as F1 in Aperture and never saw a reference to using Windows menu to list photos in iMovie. I check this and it does seem to work. however, you must admit that the procedure for adding text on a photo is limited as compare to iMovie. Maybe, it is because I want to add text to a photo for posting on Mobileme or other photo posting sites so friends can view the photos in a slideshow or one by one.
I assume that you can answer this question. Since I was exporting photos to the desktop so I could import them in iMovie, if I delete the folder on the desktop will they disappear form the project in iMovie? Since I do not like a lot of folders on the desktop can I move them to the Pictures folder and not loose the project links in iMovie?

Communicating between Database and Application

How is it possible to debug a stored procedure from the forms runtime, while it is running?

It isn't automatic ...
1. You can use plsql debugger, i.e. you have to have your procedure/function/package compiled with debug info and then invoke event 10938 (?) this will generate more information than you can handle. BTW this method is surely for the faint for hearts and should be implemented * only * after consultation with OWS.
2. Build your own debug routines, that dump informational messages at critical points in code execution. If you want to implement this, you must forget about dbms_output package. This package is completely useless in this regard. Use utl_file or dbms_pipe instead.
With some clever coding you may be able to toggle this debug message generation on/off at runtime.
3. Wait for next release of Forms9i, when used with DB 9i, you get a new debugger that is much more flexible and capable.
I have successfully implemented 1 and 2 as mentioned above. The 3rd, I heard at ODTUG 2001 from Forms Team.

Purchasing Data Not Tying Up between BW and R/3.

Hi,
As a part of our project, we reloaded the all the data related to Purchasing through the extractors
2LIS_02_SCL
2LIS_02_ITM
2LIS_02_HDR
As these were corrupted due to patch application.
We took all the possible care during reloading of all the data from R/3 like locking the user from making any transactions, Deleting the setup tables etc in a step by step process etc.
But however, after the extraction the data is not tying up between R/3 and BW Purchasing ODS.
Is there some thing wrong did we do or How can we get that missing records into BW again.
Appreciate your help.
Thanks.

Hi......
Did u fill the set up table with any selection...........?.....Previously no of records picked was larger than this time........right?..........Hav u checked RSA3 in the source system..........is it showing correct no of records........? if yes............then check the selection tab of the IP..whether u hav maintained any selection there.........
If no..........then......first check the selection in the set up table..............then the function module....which is extracting the data..........u will get the function module in RSA2.........there just double click on the Extractor.........u will get the function module name........
Anyways.........did u know which records r missed.........then just fill the set up table for those values only.........then do full load......
Anyways,............I think u know the steps in LO Extraction...........still for ur reference..........
1. Transfer the logistics DataSource for transaction data from Business Content
With the transfer of the DataSource, the associated extraction structure is
also delivered, but the extraction structure is based on LIS communication
structures. Furthermore, based on the extraction structure for the DataSource,
a restructuring table that is used for the initialization and full update to BI
is generated.
Naming convention:
DataSource 2LIS_<Application>_<Event><Suffix>; where <Event> is
optional
Examples:
2LIS_02_HDR: 02 = MM purchasing HDR (u2192 HEADER ) = Document
header...
Extraction structure MC<Application><Event/group of
events>0<Suffix>; where MC is derived from the associated communication
structures and <Suffix> is optional
Examples:
MC02M_0HDR: Extraction structure for the DataSource 2LIS_02_HDR,
where M_ indicates the group for the events MA (order), MD (delivery
schedule), ME (contact) and MF (request).
Restructuring table (= setup table) <Extraction structure>SETUP
Example:
Extraction structure: MC11VA0IT u21D2 Restructuring table:
MC11VA0ITSETUP
2. Maintain extraction structure (transaction LBWE)
This means that fields can be added to the extraction structure that is
delivered with the DataSource without modifying anything. On the one
hand, fields from the LIS communication structures that are assigned to the
extraction structure can be used, that means standard fields that SAP has
not selected, and on the other hand, customer fields that were attached to
the LIS communication structures with the append technique can be used.
After the extraction structure is created, it is generated automatically and the
associated restructuring table is adapted.
3. Maintain/generate DataSource
In the DataSource maintenance, you can assign the properties Selection,
Hide, Inversion (= Cancellation) and Field Only Known in Customer Exit to
the fields of the extraction structure. After enhancing the extraction structure,
the DataSource always has to be generated again!
4. Replicate and activate DataSource in SAP BI (=metadata upload)
5. Maintain Data Target (Data Store Object, InfoCube)
6. Maintain Transformations between DataSource and Data Target
7. Create a Data Transfer Process
the Data Transfer Process will be used later to update the data from the PSA
table into the Data Target.
8. Set extraction structure for updating to active (transaction LBWE)
In this way, data can be written to the restructuring table or the delta queue
from then on using the extraction structure (see following steps).
9. Filling the restructuring table/restructure (OLI*BW)
During this process, no documents should be created or changed in the
system! In some applications, it is possible to fill the restructuring table
beforehand in simulation mode. These results are listed in a log (transaction
LBWF). Before filling the restructuring table, you must ensure that the
content of the tables is deleted (transaction LBWG), preventing the table
from being filled multiple times. Once the restructuring tables are filled,
document editing can resume as long as Unserialized V3 Update or Queued
Delta is selected in the next step. Be absolutely sure that no V3 collection
run is started until the next successful posting of an InfoPackage for delta
initialization (see step 11).
10. Select update method
Unserialized V3 update
Queued delta
Direct delta
11. Create an InfoPackage for the DataSource and schedule the Delta
Initialization in the Scheduler
This updates the BI-relevant data from the restructuring table to the
PSA table. Since the restructuring table is no longer needed after delta
initialization, the content can be deleted (transaction LBWG).
Use the Data Transfer Process created in step 7 to update the data from
the PSA table into the Data Targets. After successful delta initialization,
document editing can resume, as long as the direct delta update method
was selected in step 13. This means that BI-relevant delta data is written
directly to the delta queue.
Note:
If the DataSource supports early-delta initialization, the delta data can
be written to the delta queue during delta initialization. This feature is
controlled with an indicator in the Scheduler.
12. Start V3 collection run (transaction LBWE)
This step is only necessary when the update method unserialized V3 Update
or Queued Delta was selected in step 10. By starting a corresponding job for
an application, the BI-relevant delta data is read from the update tables or
extraction queue and written to the delta queue.
13. Create an InfoPackage for the DataSource in BI and schedule the Delta
Update in the Scheduler
The BI-relevant delta data from the delta queue for the DataSource is updated
to the PSA table. Use the Data Transfer Process created in step 7 to update
the data from the PSA table into the Data Targets.
Hope this helps.......
