Database Adapter in process when DB is down?

Hi, I am trying to figure out what happens to an invoke activity that is calling a DB adapter if the database is down. I need to setup some error handeling around the DB being down but I am not sure what condition I should be looking for? Does the BPEL process fail or will it continue?

Hi,
The invoke process will error out with remotefault error.
It will be a unhandled exception. But if you want to have exception handle and want to terminate, then add the catchBrach in your scope or main and then add the remoteFault system error and create a faultVar and then do your operation if nay in the catchBranch scope.

Database adapter MCF configuration for jDeveloper

Hi All-
Help me to understand the mcf configuration in database adapter wsdl.
When we develop BPEL process, the database adapter wsdl file has mcf configuration mentioned in it from the connection we made in jDeveloper. wsdl file also has JNDI locaton which we actually need to define in application control of SOA suite which in runtime gets the database detail from application control of SOA suite, not from mcf details.
It always recomended to remove the mcf, is it because if the JNDI mention is not defined in the SOA application control, it may look for the mcf configuration too and if found it will fire the database connection mentioned at design time.
Thanks in advance.
Regards,
Sreejit

Hi Sreejit,
Please note that the .mcf properties has dependency on JDeveloper. As it is currently, the .mcf properties only have relevance on the platform on which the process was developed.
The process can only be worked on by another developer on another platform if these properties remain in place. If deleted, the connection information can no longer be edited in the wizard, and so the connection is effectively hardcoded. This unnecessarily complicates the development process since it results in multiple versions of a single BPEL process as it moves throughout the
development lifecycle and into Production, adding signficant busy work on top of the normal development activities. Moreover, these properties are a JDeveloper/Oracle convention and not part of the open standard WSDL specification.
Hope this helps!

BPM: Error when trying to deploy an process containing a database adapter

Hello,
We are facing an issue when we try to deploy a BPM/SOA application containing a BPM process containing a database adapter.
So, I only created a new BPM process (async process) and added a database adapter to insert something in a database, then called this database adapter in a service activity.
In the weblogic console, the DbAdapter targets are correct. I created the data source with a JNDI name, with the correct targets also.
In BPM I suppose I do not have to manually change any setting file ?
I simply create the database adapter and specify the correct JNDI name ?
when I try to deploy, I always receive the following error :

Could someone help me restore my photos? I was trying to "restore my database" in iPhoto when it shut down - now my thumbnails are distorted, logged under a new name, and when you click on a thumbnail it opens as another photo. I was following another "helpful hint" hold down the option and command key and restart iPhoto - select the top three and you should be able to get rid of the dreaded exclamation point. My MAC ran through the first two options dealing with thumbnails, but crashed during the "restore database" step and now I have a mess. Help, please. Thank you.

Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

DB Adapter call when DB is Down -- No BPEL Instance created

I have a simple DB Adapter BPEL Process. Works well. Now I shutdown then database. Problem is when I initiate BPEL Process via the BPEL Dashboard, I get the following message:
Cannot find the specified instance
If the instance has recently been initiated, the invocation data may not have been delivered to the engine yet. Refresh your browser window or try again in a few seconds.
I find no trace of this BPEL process, “Flow, Audit and Debug” all show the same message for ever!!!
Any comments would be appreciated.
Thanks.

Hi
When you initiate the process, the DB Adapter looks for the relevant dehydration store which logs the deployed bpel processes.
So, you need to have your db up, and also, mention the exact error messages being logged after turning the debug on for activation, messaging loggers in BPEL Admin.

Null Pointer Exception when invoking Database Adapter

The error reads as follows
<2008-06-27 11:34:02,558> <ERROR> <p1.collaxa.cube.ws> <AdapterFramework::Outbound>
file:/u01/app/oracle/product/10.1.3/as_mid_2/bpel/domains/p1/tmp/.bpel_UpdateA_8.2_8821b67fbd12f5dd2a0d57af136ec99e.tmp/InsertA.wsdl
[ InsertAHis_ptt::insert(AHisCollection) ] - Could not invoke operation 'insert' against the 'Database Adapter' due to:
java.lang.NullPointerException
NB Just about the same process (minor differences in the payload) was launched at just about the same time, but that one did not cause an error.
The error happened two days after a release. It was the first invocation of the service
after that release. This may or may not have something to do with this error.
There was no database shutdown, only a restart of the application server
We cannot reproduce the error; this means that we don't have an extended log with more information on the error.
Do you have more information on errors like this one?
Thanx

Hi,
To use the ServiceControl you need to be in a container that supports controls. This is what will instantiate your control for you, and take care of the some of the services controls require.
So to use the ServiceControl you'll need to invoke it from another web service, a page flow, or another control.
If you need to invoke from a standard main program, one option would be to use a standard WLS JAX-RPC client. This can be generated with their <clientgen> ant task.
Hope this helps.

Database Adapter: How to Insert when one column is an identity column

Hi everyone
I'm developing a BPEL process who uses a database adapter to insert a row in a table of an SQL Server database. The problem is that the database adapter tries to insert a null value into the field that is the primary key of the table so the process fails. This is because I don't want to specify any value to this field because this field is specified in sql server as an identity column so this field doesn't need to have a value provided.
I suppose the only solution is to set the database adapter to not insert any value to this field but how can i do that? is there any way to make the database adapter to insert data in only a few fields of a table and not in all fields, trying to insert null in these fields that no data have been provided?
Thank You Very Much!

In JDev->Applications Navigator->your project->Application Sources->Toplink->toplink_mappings.
Upon selecting "toplink_mappings" in the structure window you will see the package. Expand to see your tables. Double click your table and it will open file in main area. Select your field that has identity column. And at the botton you will see "Use Sequencing" check box make sure you uncheck it.
This will solve your problem.

Huge Delay in accessing DataBase When Net is down

Hi,
I am using MySQL 4.1.9 as the backend for my Java Application On Linux Fedora Core III.
MySQL and the Java Application, both resides in the same host.
When net (Internet) is Up, there is no delays in accessing MySQL Databases.
And its too slow when net is Down. Why ?

My best guess would be because you are establishing an rman session from your main script but it is aborting due to the error of not being able to connect to your catalog. Hence nothing happens after that.
When you run it command line seperate, it is establishing an rman session successfuly...
rman - blank session open
connect target - successful connection established
connect catalog - fails but still connected to target db from previous command
Try running rman target / catalog xe_linux/xe@gcrepo in one command line and see if it establishes an rman session or not...
Alternatively you can try putting your rman commands into your main script and run from there...
I am guessing you will still get a valid rman session connected to the target db but using the target db's controlfile.
Let me know what happens.
Actually tried connecting to a catalog db that doesn't exist and got:
[rcworarpt] /opt/oracle/admin/scripts/RMAN>rman target /
Recovery Manager: Release 9.2.0.4.0 - 64bit Production

BPEL process initiated by a database adapter causing problems in HA environ

We are having a High Availability architecture configuration(active - active) for the BPEL System in our production environment.
The BPEL servers are clustered in the middle tier of the architecture and RAC is used in the database tier of the architecture.
We have a BPEL process which is initiated by a database adapter.
This BPEL process polls a source database, reads the data, writes it into a JMS Topic and marks flag as read back to the table.
A Message Driven Bean(MDB) listens to the JMS Topic, and writes the data in the destination database.
We have the polling process and the MDB deployed to both the nodes of the BPEL server.
We have noticed that some records are getting processed by both the nodes.
This is resulting in duplicate records at the destination tables.
Kindly advise how we can resolve this issue.

The BPEL servers are configured with active - active topology and RAC is used in the database tier of the architecture.
BPEL Servers is not clustered. Load Balancer is used in front of the two nodes of the BPEL servers.

Hot to begin a BPEL process when a TRIGGER from DATABASE is on

Hello, I have acces to a database Oracle Lite in BPEL (Jdevelopper) and I 'd like to begin a process when a trigger of this table is on (when update for example) do you know how to catch this event?
Thak's a lot
Jack

Hi Jack,
Please have a look at - http://www.orafaq.com/faqpol.htm
Oracle lite databse does not give you normal RDMS database facilities (e.g oracle). If you want to have a control at the databse level, then install your SOA Suite with a Oracle 9i or 10G database.
When you do so, you can configure your trigger to call a PL/SQL procedure which can use utilities like dbms_job to call the BPEL webservice.

Nishant

"Error: null" when compiling database adapter project...

Hello...
I started to work trough the Order Booking Tutorial...
In the end there is a Database Adapter. When i follow this tutorial step by step... I got a "Error: null" at the end when compile and deploy this project...
What das "Error: null" mean? In this relation...
Connection to database is configured correctly..
Thanks for any reply..

Thanks a lot for fast answer...
I do so, and i just run through the tutorial again... Now it works...
Everything I changed except of restart jdev I change the line ( Oracle_Home\integration\orabpel\system\appserver\oc4j\j2ee\home\application-deployments\default\DbAdapter\oc4j-ra.xml )
<config-property name="platformClassName" value="oracle.toplink.internal.databaseaccess.OraclePlatform"/>
to
<config-property name="platformClassName" value="oracle.toplink.internal.databaseaccess.DatabasePlatform"/>
What does this line represent...?! So what is the platformClassName...

How do I finish updating my iPhone4 to iOS7 when it closed down during the process as I had it tethered to my computer and I assume the computer needed the internet to complete the process?

How can I finish updating my iPhone 4 to iOS7 when I had it tethered to my computer (computer using the connection from my phone) and during the updating process, when the phone restarts itself, I lose the internet connection (silly me, not thinking of this) and now it can't finish the process. Can I use a friends computer if I log into my iTunes account...as I downloaded it ok...just cant finish the update. Any ideas?
Thanks
K

If this is the third time that this has happened to you, I don't blame you for being upset. On the other hand, after the second time, you should have learned the importance of backing up your iOS devices and apparently you didn't do that or you wouldn't be in such a panic.
You cannot downgrade the iOS, You have to restore your phone now and all of the contents will be erased. I think you know that though, and I think that you know that there is no way around it either.

hi Sudeep,
We are at first hand struggling with DB adapter problem getting down everytime. Don't know the reason why.
DB adapter is in down state and when trying to make it up gives below error:
"weblogic.application.ModuleException: weblogic.connector.exception.RAException: Jndi Name is null or empty."
I just created a simple sync process using DB adapter (custom select) and deplyed successfully. I hope jndi name is not to be configured in weblogic-ra.xml file.
This is the first time we are using this JNDI name (eis/DB/calvindb).
Any inputs will be appreciated.
Thanks,
Nikhil
