ESB Error Recovery

Hi All,
I currently have a service running on the ESB, which takes an input file of 12,000+ rows and processes them in batches of 1 (PublishSize="1"). I'm using rejectedMessageHandlers to output errors to a file. The flow is: file input adapter, translation, database output adapter (stored procedure call).
My issue is that once an error is found in any row of the file, the rest of the file is ignored. As an example, if row 243 is invalid for any reason, the service writes that information to the error file, and then the file is deleted, leaving 11,700+ rows unprocessed.
Is there a way to tell the service to continue to the next row when an error is written using just ESB? We are not using BPEL or any other part of SOA. We do not want to have to manually remove the first 243 rows and then place the remainder in the directory to be picked up again if we don't have to.
Thanks in advance.

Hi
http://download.oracle.com/docs/cd/B14099_19/integrate.1012/b25307/adptr_file.htm
uniqueMessageSeparator Property
""In the case of debatching (multiple messages in a single file), the typical behavior is to reject the messages from the first bad message to the end of the file. If each message has a unique separator and that separator is not part of any data, then rejection can be more fine-grained. In these cases, you can define a uniqueMessageSeparator in the schema element of the native schema to have the value of this unique message separator. This property controls how the adapter translator works when parsing through multiple records in one file (debatching). This property enables recovery even when detecting bad messages inside a large batch file; when a bad record is detected, the adapter translator skips to the next unique message separator boundary and continues from there. If you do not set this property, all records that follow the record that errored are also rejected."
That's what you need right ?

Need suggestion on implementing JMS message error recovery

Hi,
Our application has a JMS topic where we publish application events. Now, there can be scenarios where the consumers cannot process the message due to some infrastructure issues and would error out. We need a way so that those messages can be reprocessed again later. we are thinking of the following design for JMS message error recovery
1. Use a persistent TOPIC (this would ensure guaranteed delivery)
2. Configure a error destination on JMS topic e.g a jms queue
3. Have an error handling MDB listening to the Error destination. An error handling MDB would dequeue the errored messages from error destination and persist it to a Data base "error" table..
4. Provide a mechanism to republish those messages to topic (e.g a scheduler or admin ui or a command line utility) .. The messages would deleted from database "error" table and published to topic again....
A. Are there any issues with the above design which we need to handle?
B. Are there any additional steps required in a Cluster environment with a distributed topic and distribute error destination? (our error mdb will have one-copy-per-application setting)
B. From a performance angle, Is it OK to use persistent TOPIC ? Or will it better to persist the message to the db table and then publish it as a non persistent message ... ? (But i guess the performance should be more or less the same in both of these approaches)
C. Are there any other recommended design patterns for error recovery of JMS messages
Please advise.
Regards,
Arif

Thanks Tom !
We may not be able to go with the approach of delaying/pausing redelivery of the messsage because
1. Pausing entire MDB approach: Our MDB application consumes messages generated by different producers and our MDB needs to continue processing the messages even if messages corresponding to one producer is erroring out
2. Redelivery delay : This would only delay the retry of an errored message. But there would still be a problem if the message fails during all retries (i.e redelivery limit count). We don't want to lose this message. In our case, It is possible that a particular message cannot be processed due to unavailability of a third party system for hours or may be a day.
Basically, i am looking on approaches for a robust and performant error recovery/retry framework for our application (refer details in my first post on this thread) while fully making use of all features provided by middleware (WLS). Please advise.

Arif

Satellite C640D 64-Bit Windows 7 Windows Error Recovery

Model PSC36L-003003 SN XXXXXXXXX
Boot is set to hard drive first and CDRW second.
Turn on the computer
8 seconds later it goes to Windows Error Recovery.
When I choose Launch Startup repair, it goes straight to Windows Boot manager. See #6.
When I choose Windows start normally, it goes to “Starting Windows”. After several minutes, it recycles to Windows Error Recovery Screen and then to Windows Boot Manager screen. See #6.
If I choose neither, it goes to Windows Boot manager; Windows failed to start; Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible. I do not have the Windows Installation disc.
Action taken:
Created a Window 7 64-bit system repair disk on another computer.
Changed bios boot to CDRW first and hard drive second and saved.
Inserted System repair disk into CD drive.
Turned on computer and pressed any key.
Windows loaded files from repair CD disk.
A Windows blue background screen with leaves appears without Windows logo (not the blue screen of death); files load and cursor appears; CD stops running; but nothing else happens with screen for eight hours.
I do not have the Windows Installation disc.
Please, what do you think is wrong with the computer or what should I do next? Your help will be greatly appreciated. How do I confirm that it is Windows 7 32 or 64 Bit? I am trying to fix this for my friend who probably bought it in the Indonesia area. Thank you in advance.

Something wrong with that repair disc or the hardware. The bitness of Windows on the hard drive should not matter at this point. I would burn another disc and try again.

HP Pavilion dv6 1334us won't start after windows update, stuck in Error Recovery

My computer is an HP Pavilion dv6 1334us with 32bit-windows 7. The computer did automatic updates and when it started up said there was another one avaliable through WIndows Updater. I installed the update and it said the computer needed to restart for the update to take effect. I choose to restart and the computer wouldn't boot back up, it boots to the 'Windows Error Recovery' screen where my options are 'Launch Startup Repair (recommended)' and 'Start Windows Normally'. When I select the repair, it says it loads windows files, then goes back to the error recovery screen. When I choose to start normally, it freezes the second it trys to start, flashes a blue screen and then returns to the Error Recovery page again.

Please follow the steps in the following document to troubleshoot and fix the boot issue that you are facing.

HP G62 Windows Startup error recovery Failure

Notebook:
HP G62 - 228CL
Running Windows 7 64-bit
Hello everyone, I need a bit of help.
My computer will boot windows 7. When I start it up, it tries to boot up. I then get a Windows failed to boot message on the windows error recovery screen and asks me if I would like to use Windows Startup Repair Tool to fix the Problem. But the tool never starts up. It just leads to a windows background and does nothing. I have also tried using f11 System recovery but it does nothing.

Hi,
Firstly, regarding your existing files.
One possible way to try and retrieve your files from a non-booting drive is to follow the process detailed in the link below. The Ubuntu operating system CD you create can run from the CD alone ( ie it doesn't have to install on the Hard Drive ) and I've often found it to be successful in retrieving data even from a failing Hard Drive. When you've created the CD, follow the instructions and see if you can back up your existing files.
http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windo...
Secondly, regarding the replacement of the Hard Drive.
The drive on the link below is an example of one that would be fine for your notebook.
500Gb Hard Drive
The procedure to replace the Hard Drive starts on Page 52 of your Maintenance & Service Guide.
Once done, simply use your Recovery DVDs to reinstall the Operating System on the new drive - the procedure is described in the HP document Here.
If you don't have your Recovery Discs, you can order a replacement set using the link below.
Order HP Recovery Discs.
If you have any problem with this link, order them directly from HP.
If you live in the US, contact HP Here.
If you are in another part of the world, start Here.
Best regards and happy holidays,

ESB error handling and notification features

Hello everyone,
I am newbie to oracle SOA ESB. I am an oracle apps guy.
This being my first post to this forum, I have a lot of questions. :-)
For a small intergration requirement, we are looking for a good integration tool
Some requirements are:
1) Flat files will be generated by concurrent programs on oracle apps which need to be transferred to legacy systems.
2) Pick the data from apps tables and insert them into another database. Not much translation required.
After some research, found ESB to be a good fit.
Before actually start using it, we wanted to do a couple of POCs.
So far we are using shell scripts for ftp process. We opted for an integration tool to have DB to DB transmission. Apart from this we need better error handling and error notification mechanism.
Some error conditions:
1) Unavailability of ftp server or Database server.
2) Permission issues. Say some files may not have read, write, deletion permissions. They need to be caught and notified.
3) Mandatory field missing while inserting data which is read from a flat file into a DB table etc..
My initial thoughts on error handling are:
Connection error: To retry for connection errors. If the retry fails send notification via email and also write the failed connection details into an error log file(apart from the server log file).
Data mismatch: NOtification to be sent with the error details.
I would like to know What happens to the file if the destination ftp server is unavailable while ESB is trying to FTP the file. Will ESB retain the file with itself and FTP the file once the ftp server is up?
In BPEL I could see try catch blocks which can be used to handle the errors and thus send notifications.
ESB documents introduced terms like error hospital related to error handling but I was not able to figure out a way of implementing them. As I am not well versed with XML and WSDL I am probably unable to use the fault tab which is in the routing service. I feel Oracle could have given some samples that explain about ESB error handling.
Also to my dismay, adapter docs say that there is a limitation of 7MB size for ftping. Although our file sizes often fall below this size, I would want to know if there is any workaround to over come this size constraint.
I think I put a lot of stuff in a single post and may be in the most haphazard way. Please bear with me.
Please suggest me of some documents if any related to my questions.
Would be really great if you can give me a straight forward solution to all the above problems
Hope this forum would be a great help to me.
Cheers,
Robert.

I have worked on a few SOA Apps implementations. Some successful and some not so. It really comes down to the type of integrations.
But I would say the majority of your integration will be batch as this is what eBus is all about. If this is the case then I would recommend Oracle Data Integrator. If you go Oracle Data Integrator Suite it includes Service Bus and BPEL. ODI has an eBusiness Suite adapter as well.
The good thing about ODI is that you can use it for data conversion, that conversion can then be reused once live, so the conversion is not throw away.
In SOA 10.1.3.4 the limit of 7MB has been resolved but you must be using the file / FTP adapter for input and out, from the sounds of it you want to call concurrent programs so this probably wouldn't work.

Help me, pls! Getting Windows Error Recovery of windows 7

Hi, my computer is in problem. It's Windows Error Recovery. Then, I did the steps by computer,I clicked the Startup Repair(Recommanded). A startup repair window appears and it scans the problems. It's scanning, I waited for several hours.. but it's scanning and scanning endlessly! It says "recovering disk error,this might take over an hour to complete".. yeah, more than an hour, I waited for five hours, nothing changed..scanning and scanning... What should I do?....

Hi,
Try tapping F8 on startup to check if it loads to Safe Mode..If it loads to Safe mode then you can perform a System Restore...Also check the hard drive by tapping F2 on startup..
OR,
Try the steps mentioned in the link below:

ESB Error Hospital and Rejection Handlers

Hi,
I am getting confused with ESB Error Hospital and ESB Rejection Handlers? Can anyone of you explain me what is this?
Thanks,
Gomathi

Rejection Handlers are used for adapters such as file adapter. When these fail during the invokation of the ESB, you can perform some operation, e.g. call a BPEL process. The default is to write to a default directory. But no notifications are made.
The error hospital is an error handlers for when the process fails in flight. This allows use to send notifications and retry if required, etc.
Here is a good doc on the subject.

Sql...forward error recovery

in the recovery technique know as forward error recovery, on the detection of a particular error in a system, the recovery procedure consists of adjusting the state of the system to recover from the error. Can such a technique be used in a DBMS to recover from the system crashes with the loss of volatile storage? thank you.

Randy,
This sounds like an issue with the BRTOOLs then. 1722 is a rare error where the SQL statement attempts to convert a string into a number - like a date in this instance.
You may need to open a ticket with SAP Support and have them look at the issue, as you may need a fix for the toolset itself.
Sorry I could not be of more assisatance Randy.

How does BPEL Fault Management Framework gel with ESB Error Handling ?

I see that BPEL 10.1.3.3 has pretty neat Fault Management Framework (although I have to admit it is not very well advertised).
The next logical question is: what about ESB ? Would that help in ESB error handling ? I understand that ESB has its own Error Hospital etc.; however, we have to constantly grapple with two distinct paths for any piece of integration functionality (1. ESB 2. BPEL). I guess, all of this will be moot in the 11g timeframe. Still wondering if anyone out there has somehow unified error handling for these two distinct offerings ?

It's not available in ESB, you have to implement/extend that by your self. Off course in the next release everthing will be better :-)
But, if you are able to use Oracle AIA (http://edelivery.oracle.com) You could use Oracle AIA Foundation, that has a fault 'hospital' implemented both for BPEL and ESB.

ORABPEL- 0803 JTA Rollback - ESB Error

My scenario is as follows - I have an ESB service that is inserting data into a target database. I am pasing data into the ESB from an ochestration BPEL process. When the database is down the ESB DBadaptor fails and the ESB returns the following error to the BPEL process invoke activity and the process hangs with the invoke highlighted in red. Wen I drill into the code I can see the following return element.
<fault>
ORABPEL-08034
JTA Rollback requested.
The current JTA transaction has been aborted due to rollback request received from partner invocation.
</fault>
Firstly this is causing me problems because it is not throwing an error in BPEL so my catch is not catching the error even though it is being passed in a fault element. (I would have expected it to get caught in the catch all branch of my process)
Secondly why is the root error from the DbAdaptor in the ESB not being sent back?
Is this a fundamental issue with ESB error handling?
I would be happy if the Fault above was thrown and the fault was caught in the catch all and my process would handle this but it just hangs when the invoke activity fails.

Hi,
I applied the patch MLR6 and now has following scenario.
ESB is not even returning any fault when database adapter operation fails. I have been through the documentation available in Metalink and as per that the problem ESB Does Not Return Faults to BPEL (doc id 728491.1) should have been solved after applying MLR6.
This is referenced with bug no 5997936 which has been solved even before that in 10.1.3.4 Patchset for Oracle Application Server 10g Release 3.
Now I am confused. Please help. Following is the error log for reference
An unhandled exception has been thrown in the ESB system. The exception reported is: "org.collaxa.thirdparty.apache.wsif.WSIFException: esb:///ESB_Projects/TestESBServices_TestDBAdapters/PersonDetailsDBService1.wsdl [ PersonDetailsDBService1_ptt::insert(PersonDetailsCollection) ] - WSIF JCA Execute of operation 'insert' failed due to: DBWriteInteractionSpec Execute Failed Exception. insert failed.

Error recovery in OpenScript

Hi Alex,
My script always fails due to a timeout issue when invoking a CAS comman in Siebel functional test.
How can I use error recovery methods to ignore this particular error and prevent my test from failing?
Thanks in advance.
Here is the code where it fails:

Hi Alex,
I have the SiebelFT method and I tried to increase it to 120 and even 300, but nothing has changed. The timeout error appears a few seconds after the CAS command is executed, and the scipt continues to run properly after the exception is thrown, but at the end it fails with the timeout error message.
I have been trying to solve this out with Oracle support team now for more than 2 months, and nothing worked so far. I am starting to have the feeling that my case is hopeless.
Please help me in this, it is blocking a lot of my work.
Thanks

Bdc error recovery

Hi,
plz any body tell me the best method of error recovery in bdc both in call transaction and bdc session, since data is in huge ammount and in excel sheet.
plz give me answer in full details, bcaz i am is in big trouble uploading around 40 lakh line of data in implementation project.
thanks and regards
vijay dwivedi

Hi Vijay,
The general practice is that you for such huge data, BDC session is the better option. When you create the session using the program, you can go to sm35 and process it at a later stage. Once the processing is done, an error log is created automatically with all the records that have failed. YOu can then analyse the reason for the error by running a few of those records in E mode(Error screen mode) correct the data and reprocess the error records.

Ravi
