OSB polling process

Hi
I have a requirement where i need to create an OSB process which connects to a DB,executes a sql query at regular intervals. In other words a polling process which executes every 5 min
Can some one suggest me how to go about it.
Thanks in advance

Use "Poll for new or changed records in a table" operation of DB adapter. Please refer below post to know how to use JCA DBAdapter with OSB 11g -

OSB Polling in Cluster Environiment

Hi ,
I created a OSB Poller which will read data from DB. When I test it in a single server it is working fine but when I move it to cluster environment with two managed servers it is polling Twice from the DB and the reports are generating twice . I have changed the JCA Property <Lock>lock-no-wait</Lock> even then it is polling twice. Any solution Please ?

Database polling process

I have created a bpel database polling process to process a single table and use a logical update (mark a column as processed). The table will contain many unprocessed records at any time. I have setup the polling interval 5 Sec and records unlimited for each polling interval and in the process i am calling a stored procedure to insert same data into another database.
My doubts
But It fetches only one record and different instance is created for every Row. Is it normal process?
Why it takes only record after using unlimited option?
why i am asking this means i don't want to call stored procedure for each and every record.
I'm using MS SQL Server 2005.
any one pls let me know what is happening inside.

Depends on how you define performance. DBs are generally designed for this kind of load so you then need to look at the middleware. The concern I always have is how big can this message get. If it can potentially grow big, I would say over 10MB then you could run into trouble if you haven't tuned for that, 1 10MB file could hang your whole system if not tuned (extreme case to make a point). If you have it running row by row it may take more time but they will go though. Without knowing more about your environment I can't comment too much more, e.g. patterns, hardware, load etc.
Also polling isn't the most effective way long term to invoke a message. If the table is going to grow large I would look at partitioning as that select statement will deteriorate over time as you don't delete the records once read. ( I'm just trying to give you things to think about it may not be relevant your your site)

OSB Service Processing time

Dear all,
we have requirement to find out OSB Service Processing time. can you please suggest how we can get this information using OSB Console or if ther are any JMX Api available to get this data.
requirement is: to know the actual execution time in OSB Request processing time.(should not include target system processing time)
thanks in advance.

You can use inbuilt service monitoring (Oracle Service Bus Monitoring Framework) functionality to find out the same...

BPEL polling process open new connection every time it poll for data.

Hi All,
I've created a BPEL process that with a database polling process for an AS400 table and the log is showing the BPEL process is opening a new connection every second. Is there a way to create a polling process that will only use one connection and keep the connection open.

This is dependent on the SOA Server configuration not your service. To change that login to EM console and find appropriate configuration entries in administration tab of your OC4J instance.
Unfortunately I don't know exactly which one (or more that one) is responsible in your case. I didn't trouble about that ever before, for me it can be even million connections as far as it is working smoothly.

OSB Polling in sequence

We have the following scenario.
I have to poll a database using DBAdapter in OSB for populated records.
The records must be processed in order for eg InsertEmp , UpdateEmp and DeleteEmp are events and must be delivered in the same sequence.Delete should go not go first before Insert.How to achieve this using the DBAdapter.Could this be done with any inbuilt columns or the ROWID in the table.
The polled records are written to a JMS.How to again avoid any wrong sequencing incase of clustered queues.
Thanks.

Hi,
The requirement may sound simple, but it is actually very difficult to implement 100% guaranteed messaging ordering... You pretty much have to reduce everything to a single thread approach, and that will probably have impacts on performance...
For the weblogic JMS side, there is Message Unit-of-Order... So if you can get there ordered you should be ok... Have a look on the limitations at the end of the page...
http://docs.oracle.com/cd/E23943_01/web.1111/e13727/uoo.htm#JMSPG389
For the DBAdapter Oracle documentation clearly states...
When polling the database for events, you can order the returned rows by the selected column by using the Order By list. The best practice is to choose <No Ordering>, as message ordering regardless is not guaranteed without extra configuration.Unfortunately it doesn't say what's that extra configuration needed to do it... At least I couldn't find...
I would try some of the following... They are all in this document http://docs.oracle.com/cd/E23943_01/integration.1111/e10231/adptr_db.htm
Doing Synchronous Post to BPEL (Allow In-Order Delivery)
Update a Sequencing Table
Specifying Advanced Options... Look for GetActiveUnitOfWork...
This is a very interesting topic though, please let us know how you go...
Hope this helps...

OSB 10gR3 - Process WS-Security flag not working with PasswordDigest

Hi,
By Oracle documentation when you set the "process ws-security header" in security section of a proxy service, the proxy service act as an active intermediary and consume the ws-security header received in inbound messages. This feature works fine when you call the proxy service using WS-Security Username Token Profile PasswordText, but when you send Username Token with PasswordDigest I got the following error: +"weblogic.xml.crypto.wss.WSSecurityException: Unable to validate identity assertions"+
I am using SoapUi to call the proxy with passwordDigest, WSS-Password Type option set to PasswordDigest.
Proxy configured with:
General tab -> WSDL based proxy service, this wsdl doesn't have ws-policy definitions inside.
Transport tab -> Get all headers = Yes
HTTP Transport tab -> HTTPS Required = No / Authentication = Basic
Operation tab -> Enforce WS-I Compliance = not checked / Selection Algorithm = SOAP Body Type
Message Content tab -> default settings
Policy -> Added Auth.xml(predefined) policy to request policies.
Security tab -> Process WS-Security header = Yes / Custom Authentication settings = none

Eduardo,
Yes, but the flag "Process WS-Security header" needs to be set to 'No' and I included a delete node to remove the wsse:Security element from header. Attaching Auth.xml predefined policy to my request operation, causes OSB to include the policy directive in my WSDL, but the PasswordText(see below).
In Oracle security guide we have steps to configure PasswordDigest in the Oracle Service Bus Security Configuration using the WLS Console http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/security/model.html#wp1062542
My doubt is: Is this a bug? "Process WS-Security header" flag is supposed to work with PasswordDigest?
My WSDL with WS-Policy statements after Auth.xml policy was configured.

Looping a polling process

Hi all
We have a requirement for our process to poll the DB first and in case our condition is not satisfied, we need to poll it again. Is there any basic help note for this.
I am thankful for any inputs
Vijay

I assume you want this function mid process and not to invoke a BPEL process. Therefore the answer is yes this can be achieved.
Create a temp variable and set it to false. Create a while loop with the expression when temp = false. In this loop call you DB routine, if it gets a result then set temp = true.
The issue with this is that this can loop many times. The console struggles to draw a BPEL process if it is large, 1000s of activities. So if an error occurs you may not be able to see the cause.

OSB logging - Process writes logs in both osb_server1.out and log file ..?

Hello,
I have few OSB proxy service and we have configured few log operations for logging but while testing, I noticed logs are getting written in both osb_server1.out and osb_server1.log file. I dont want to write logs in osb_server1.out file.
I am running my weblogic server in development mode.
Could someone please advice me whats wrong I am doing here.

OSB Parallel Processing using OSB

Hi All,
I am working on a proxy service based on WSDL-A.
Stage-1
I have to do a service callout (sc1) to another business service with a particular parameter.
From the response of that sc1 i need to pick two variables var1 and var2 and use it the request of stage2 and stage 3.
Stage- 2
I have to do another service callout (sc2) to the same business service with a particular parameters including var1 returned by sc1
Stage- 3
I have to do another service callout (sc3) to the same business service with a particular parameters including var2 returned by sc1
Stage-4
I need to Use the response of sc1, sc2 and sc3 and transform that to the desired response.
My only concern is I have to wait for stage 2 to complete to start with stage 3 when I have no real dependency on stage 2.
How can I ensure that My stage 2 and stage 3 can be processed in parallel. ?
Can any one please explain How I can achieve that?

Hi Edwin,
I was trying the example on your blog I am getting this issue that I am not sure how you initialize the response.
It always gives me an exception that the response is used before its is initialised.
If possible can you send me the configuration jar on my email [email protected] ?
Cheers Nitin

OSB singlethreaded processing PS not working when delivery failure is set

Hi,
Below is my process flow
JMSQ -> JMS PS -> BS - > Endpoint
So i have the requirement to send the messages one at a time so i did 2 settings
1. JMS connection -> Max messages per session =1
2. Created WorkManager with Max threads 1
This works fine in case of normal processing
But now i have a requriement to add a redelivery limit and redelivery interval in the Queue to route to error queue in case of error
So in the delivery failure tab i changed the values..
So when i do this change all the messages are consumed at once retried and roll backed. I need messages to be consumed one by one and retried.
Am i missing some thing? Or singletonprocessing wont work with ReDelivery can anyone please suggest?
Appreciate your help.

Any suggestions on this?

Logical Delete in DB Polling - OSB

Hello All,
I have a question in polling. I have a logical delete column with Read value as 'P and unread value as 'N', Unlike BPEL, OSB's polling, does not make a record to 'P' until the process completes successfully. My DB polling adapter polls the same records while the previous instance is under processing or the previous instance ended in error. Is there a way to logically delete the record immediately once the record is read?
To avoid this scenario, I added an error handler to make the record to 'E' if the instance encountered any error. By the time the error handler kicks in and updates the record, OSB polls the record a few times. I increased my polling frequency from 5 seconds to 30 seconds, but no luck. Any clue how to handle this scenario?
Thanks,
Dwarak

Is there a way to logically delete the record immediately once the record is read?Dont do any logic in db adapter proxy. Instead make the proxy to just write to a jms queue and then have your processing logic in the jms proxy service which reads off the jms queue.

DB Adapter polling as singleton process is not working as expected

Am using poller DB adapater to control the transaction per seconds to the downstream system and i want this poller process as singleton (One instance should be in running state at a time).
As suggested in oracle documents , below is the parameters configured in composite.xml file.
<service name="polling_Mange_Alert_Events"
ui:wsdlLocation="polling_Mange_Alert_Events.wsdl">
<interface.wsdl interface="http://xmlns.oracle.com/pcbpel/adapter/db/Application1/int_app_manageAlerts/polling_Mange_Alert_Events#wsdl.interface(polling_Mange_Alert_Events_ptt)"/>
<binding.jca config="polling_Mange_Alert_Events_db.jca">

</binding.jca>
<property name="jca.retry.count" type="xs:int" many="false" override="may">2147483647</property>

    </activation-spec>
</endpoint-activation>
</adapter-config>
This poller process is running on clustered environment (2 soa nodes) and it is not working as expected as singleton process.
Please advise to solve this issue ?

Hi,
1.Set Singleton property outside   <binding.jca> like this:
<binding.jca config="polling_Mange_Alert_Events_db.jca"/>
<property name="singleton">true</property>
<property name="jca.retry.count" type="xs:int" many="false" override="may">2147483647</property>
<property name="jca.retry.interval" type="xs:int" many="false"
2.Also you can try setting these values in jca file:
<property name="RowsPerPollingInterval" value="100"/>
<property name="MaxTransactionSize" value="100"/>
3. try to increase the polling interval time.

Anshul

Osb jca adapter weird behaviour

Hi gurus,
Im running OSB 11.1.1.5 having a db adapter polling an MSSQL2000 table (SELECT WITH (UPDLOCK, NOWAIT)..)
The table is being filled by a long running transaction.
I observe in the JCA logging the following error on every polling iteration while the table is being filled:
<Jan 10, 2012 2:00:45 PM CET> <Error> <JCA_FRAMEWORK_AND_ADAPTER> <BEA-000000> <<oracle.tip.adapter.db.InboundWork handleException> Encountered a fatal exception while polling. Will continue polling but with minimal logging. Please investigate the fault and manually stop polling from the console if in development and this appears to be a modeling mistake. BINDING.JCA-11624
DBActivationSpec Polling Exception.
Query name: [O_Boeking_I_PollerSelect], Descriptor name: [O_Boeking_I_Poller.OBoeking]. Polling the database for events failed on this iteration.
Caused by java.sql.SQLException: [FMWGEN][SQLServer JDBC Driver][SQLServer]Lock request time out period exceeded..
This exception is considered not retriable, likely due to a modelling mistake. To classify it as retriable instead add property nonRetriableErrorCodes with value "-1222" to your deployment descriptor (i.e. weblogic-ra.xml). This polling process will shut down, unless the fault is related to processing a particular row, in which case polling will continue but the row will be rejected (faulted).
The issue I'm experiencing occurs after the long running transaction is done. What I see is that in the next polling sweep 2 XML documents are delivered by the db adapter engine...I cannot figure out why. I do not want this
1 document contains only 1 record. The other document contains the rest of my records.
Have tried both WebLogic and MS JDBC drivers.
Some of mine properties:
MaxRaiseSize = 0 (I want all the records in 1 XML document)
MaxTransactionSize = unlimited
Thanks alot

Veejay,
Have done so...I tried some different setting like test-connections-on-reserve (was off)...no successes here.
I will give a try with another mssql driver version.
Another interesting thing I have observed is when I do not commit the long running transaction, the next db adapter polling event results in this exception:

This lets me think it could be a bug..

Multiple proxy services Polling on same Table

Hi All,
I have 2 proxy services in OSB Polling on the same status column in orders table.Proxy1 polls on status 'N' ad Proxy 2 polls on status 'Z'.However I see that only one proxy service is polling the orders table.Even though there are records with status 'Z' in order table the Proxy2 process is not started.Kindly let me know how this can be resolved at the earliest.
Thanks & Regards,
Radha

Hi All,
In my case when the first polling process was running the 2nd polling process was not running.So I undeployed the 1st process and then the 2nd polling process started running.Now again i deployed process1 polling process and both the processes were running successfully.
Thanks,
Radha
