Polling adapter fails unexpectedly

Trying to test ESB polling service.Created sample polling service that check for database table changes. Service does not work properly, found error message in log.xml file:
JCA inbound adapter service listener for "Fulfillment.TestPooler_RS.receive" with endpoint ID "[TestPooler_ptt::receive(CustomerCollection)]" has been requested to shutdown by Resource Adapter due to fatal error. Reason : ORABPEL-11624
DBActivationSpec Polling Exception.
Query name: [TestPooler], Descriptor name: [TestPooler.Customer]. Polling the database for events failed on this iteration.
If the cause is something like a database being down successful polling will resume once conditions change. Caused by Exception [TOPLINK-6024] (Oracle TopLink - 10g Release 3 (10.1.3.1.0) (Build 061004)): oracle.toplink.exceptions.QueryException
Exception Description: Modify queries require an object to modify.
Query: UpdateObjectQuery(null).
What can be cause of this error?

Hi alex,
Cause of problem
Both OC4J running BPEL and the database adapter reached the maximum number of connections and were unable to establish new ones.
The reason for the problem is a database adapter Bug 5595347.
According to Bug 5595347, the database adapter might leave open connections behind.
The fix for Bug 5595347 is included in Patch 5638122.
Solution
To implement the solution, please execute the following steps:
Apply Patch 5638122.

Stopping DB-Polling-Adapter when failure in mediator

Hi
I have a DB-Polling-Adapter that posts data directly to a mediator. When data is readed mediator does a logical delete, e.g 2 for field readstatus. So during reading readstatus is 9 and before 1.
When a failure happens in mediator (during xsl-transformation) mediator throws failure back to DB-Polling-Adapter. The problem is now that state of readingstatus is still 9 and after each polling sequence adaptor reads and posts same data again and the failure happens also.
Is there any posibility to send failure into error hospital and to set readstatus to 2, so that adapter doesn't poll the same data on and on? Catching mediator fault in fault-policies doesn't work.
I found two solutions: 1. Send data from Polling-Adapter to BPEL, 2. Sematron validation but it doesn't cover all posible failures.
Example failure during transformaiton:
ORAMED-03303:[Unexpected exception in case execution]Unexpected exception in request response operation "execute" on reference "Convert_JDE-to-Common". Possible Fix:Check whether the reference service is properly configured and running or look at exception for analysing the reason or contact oracle support. Cause:oracle.tip.mediator.infra.exception.MediatorException: ORAMED-01201:[Error in transform operation]Error occurred while transforming payload using "xsl/F0006Collection_To_ProjectsCollection.xsl" for target part "reply".Possible Fix:Review the XSL or source payload. Either the XSL defined does not match with the payload or payload is invalid
Thx a lot for help.
Pascal

Issue solved.
Setting jca.retry.count=unlimited causes the adapter to behave as we want.
We had set jca.retry.count = 1 on the mistaken understanding that this related only to a failure to query/poll the database, and that sequence number was updated in a separate context that needed a global transaction to coordinate/rollback.
We don’t even need to propagate our global transaction from polling adapter to bpel component since all our writes happen in an OSB transaction; Our bpel just (re)throws a fault back to the polling adapter which is enough to trigger retry.

File adapter fails to pickup the complete file

Hi Guys,
I have a file to idoc scenario configured.
Sender is an FTP server and the file type is XML
Here are the details of my file adapter
FTP Connection parameters,
Connect Mode      : Permanently
Transfer Mode     : Binary
Processing parameters,
QoS     : Exactly Once
Poll Interval     : 15 secs
Processing Mode     : Archive
Most of the time my scenario works perfectly fine.
And sometimes my file adapter fails to pickup the complete xml file and my scenario fails.
The file is read partially and my mapping throws an error.
Am i missing any parameter to be set in File adapter???
Thanks in Advance,
BBnu

>>The file is read partially and my mapping throws an error.
Thats the normal behaviour of XI,if you get a partial file,you will get a error message.
There are several work arounds for this,first of all have a script independant of XI which is running on FTP server,this script will keep on checking for modifications in file and once the file is completely written,it will rename the file to some other extension(for e.g .dat) and XI file adapter will only pick .dat file,this will make sure that only complete files are picked up.
Second option is to have a tag all the way in the end of XML which says EOF(of any other character),in your mesage mappin create the root node of target only if this last tag is EOF.Since in incomplete file you will not have this last tag,message processing will stop.
Thanx

Can't enforce sequence with polling adapter when faults

I'm trying to process records in sequence using a polling adapter and the update sequence table strategy
I have a polling adapter that invokes a composite app which calls an OSB service over http/soap.
polling adapter -> composite app -> OSB -> db adapter
On successful processing, the polling adapter updates a sequence table.
In the event of a fault, I expect the sequence table not to be updated and the failed record to be tried again on the next polling interval. However, even on failure, the sequence table is being updated.
My bpel component has the property
<property name="bpel.config.transaction" many="false" type="xs:string">required</property>
.. and a catch clause which throws a rollback on remote faults
The next polling interval picks up the next record and the problem repeats. We have then 'lost' the unprocessed record(s).
How can I force the polling adapter to block on failed records?
Thanks
Garret

HI,
Welcome to Lightswitch forum.
As you mentioned above, if you want to build and deploy your lightswitch application to IIS, first you need configure a Web Server to host LightSwitch applications. At the same time there are more hints for us to configure web server, and then configure
the deployment procedure, for more resource:
LightSwitch IIS Deployment Enhancements in Visual Studio 2012
Please let me know if you have any concern.

Error in crawl log "Error while crawling LOB contents. ( Error caused by exception: Microsoft.BusinessData.Infrastructure.BdcException The shim execution failed unexpectedly - The method or operation is not implemented..; SearchID "

Hi
I get the following error in my crawl logs
"Error while crawling LOB contents. ( Error caused by exception: Microsoft.BusinessData.Infrastructure.BdcException The shim execution failed unexpectedly - The method or operation is not implemented..; SearchID "
Because of this i suspect, the search results are not including those aspx pages marked as "Hide physical urls from search".
This error is not available in the another environment where the aspx pages are coming in the results.
Thanks
Joe

Hi Joe,
Greetings!
Reset the index and re-crawl. That usually clears it
If you are using NTLM authentication, then make sure that you specified the PassThrough authentication for crawling
Probably you need to debug the BDC code that underlies the external content types.

HP Officejet Pro 8500A Plus AC Power adapter failed. Where to buy?

My AC power adapter failed. Where can I purchase a new one in Doha?

There should be an electronics store near there. Go into google maps, bring up Doha, then search nearby and put in 'hp printers' which should be up some sort of electronics retailer.
If that doesn't work, then go to HP.com, put in your printer model, and follow the links, and you should be able to order one online. Just make sure you specify your region in your search, so that it doesn't think you are in Ireland, when you are actually in Qatar.

JCA Polling Adapter not picking up records

Hello All
I have been trying to configure a JCA polling adapter to pick up records from the Database, the first time I configured it, it read a whole bunch of records. Now I have configured the following in the database and am getting no records being polling.
1. Poll for new or changed records
2. Update a field in the table F40g02 for logical delete
3. Read value = READ, UNREAD value = UNREAD, Reserved value = RESERVED
4.Polling interval 5 seconds, Database XROWS per xml document 1, Database Rows per Transaction 10
I ran the SQL specified in the adapter and I get a record. Does anyone have any idea.
I have seen this warning in the EM
Database Adapter <oracle.tip.adapter.db.inbound.IPAddrPollingService getUniqueMarkReservedValue> The markReservedValue of distributed polling might not be a unique value. To make it so, you can add the last x digits (default = 2) of the host IP address using this format for the MarkReservedValue: [original_val]${IP[-x]}
Regards

Hello
The problem I am facing is I can't get the records that are processed (already READ) to not poll again despite the value being changed to the READ value configured, if I set the READ value in the configuration it will poll every record all the time despite the fact it is equal to the READ value. Then if I set the READ value and any other value no records will poll.
Consider 4 records in the DB (currently in test I have 431 but I have used distributed locking and ReturnSingleResultSet to limit it)
ID = 1, STATUS = PROCESSED
ID = 2, STATUS = UNPROCESSED
ID = 3, STATUS = UNPROCESSED
ID = 4, STATUS = OTHER
Config 1: If READ = PROCESSED records 1,2,3,4 will poll
Config 2: If READ = PROCESSED, UNREAD = UNPROCESSED no records will poll
Config 3: If READ = PROCESSED, UNREAD = UNPROCESSED, RESERVED = OTHER no records will poll
Config 4: If READ = PROCESSED and TOPLINK STATUS not equal string "PROCESSED" then records 1,2,3,4 will poll
What I want is Record 2 and 3 to poll which I believe is config 3 should do. However I believe there have been some changes that relate to distributed polling for clusters in 11.1.1.3 onwards which means in jdeveloper (11.1.1.6) when I go to re-config the db adapter after setting the RESERVED value it disappears from the editor .
JCA properties obviously with a MarkReservedValueand MarkUnreadValue column jumping in.depending on which config I am trying
      <property name="DescriptorName" value="dbPollBlockRecords.F40G02"/>
      <property name="QueryName" value="dbPollBlockRecordsSelect"/>
      <property name="MappingsMetaDataURL" value="dbPollBlockRecords-or-mappings.xml"/>
      <property name="PollingStrategy" value="LogicalDeletePollingStrategy"/>
      <property name="MarkReadColumn" value="STATUS"/>
      <property name="MarkReadValue" value="PROCESSED"/>
      <property name="PollingInterval" value="700"/>
      <property name="MaxRaiseSize" value="1"/>
      <property name="MaxTransactionSize" value="10"/>
      <property name="NumberOfThreads" value="1"/>
      <property name="ReturnSingleResultSet" value="true"/>   (This property has been manually configured, will unfortunately poll all records that match without it)

FTP Adapter fails first time when bpel process is invoked from concurrent

Hi,
We noticed that the invoke of the FTP adapter fails the first time when the bpel process is invoked from a concurrent program. The second time the concurrent is ran, it completes fine. However, when invoked from the console, it compeltes fine the first time itlsef.
Any idea what could be worng. We are on SOA Suite 10.1.3.4

What you are doing with FTP adapter? Are you writing a file ? Any error details in logs when it is failing on first invocation ?

How to send alert when receiver JMS adapter fails? Please help!

Hi experts,
   I have the following Asynchronous scenario:
   SAP R/3 -
>IDOC----->XI>JMS--->BizTalk.
   I am sending IDOC from a given SAP R/3 system to XI. XI then sends the same to BizTalk via JMS adapter. In SXMB_MONI the message is successfully processed as it shows checked flag. But if I see the JMS communication channel status in runtime workbench then there it shows error saying JMS queue user id or password not found.
How to send this JMS adapter error as alert?
I also tried configuring alert rule in runtime workbench but still it does not trigger any error.
I have also verified the alert category and everything is fine with that.
What could be the problem? How can I send an alert when an Async adapter fails?
Thanks & Regards,
Gopal

Hi! GOPAL,
Once make sure whther all the below mentioned steps are configured correctly or not ok
1: First make sure whether you are working on SAP XI or PI 7.1
           a) If XI you need to create Alerts (ALert Category) in CCMS ABAP stack in the
                    Tcode. ALRTCATDEF
           b) Open the alert category/classification definition environment (transaction ALRTCATDEF).
     ensure you are in change mode.
           c) In the group box with the alert classifications, right-click All classifications to open the
                context menu, and choose Create.
           d) Under Classification, enter a name for the classification.
           e) Under Description, enter a description of the classification.
           f) Save your entries.
           g) Then go to RWB-->Go to ALERT Configuation and ADD the RULES to your alert category gor
     which created there in the abap stack.
Note Suppose if you want those ALERTS to come to your MAIL then again go to ABAP STACK and go to Tcode. ALRTCATDEF and select your alert category press FIxed Recepients and there give your SAP XI ID's then u can see those alerts in RWB-->ALERT INBOX
Suppoe if you want those to mail then ask the basis team to link your company mail or personal mail ID to your SAP ID.
2. Supppose if you are working on PI 7.1 Server.
     Only difference is creating Alert Category...Here you can create your ALERT Classification I mean
     alert caltegory in the ESR (Enterprise Service Repository )
     Software Component >S CVersion>NameSpace-->Alert Category.
     You can configure how u configure there in abap stack such as long and short text every thing
      except Fixed Receipients you need to give that recepients there only in ABAP STACK.
      what ever ALERT CATEGORY you are creating will reflect there in the ABAP STACK
     even you can Use these alerts Category in BPM --> CONTROL STEP -->Configure here in this step
You can also reach alerts like this.
NOTE Most Important point is You can also view your mails or Alerts in the T Code:: SOST.

Amar Srinivas ELi
