XA Trasaction issue with SAP JCA Adapter

Using OSB 10gR3
We have a proxy picking messages from a JMX queue using an XA enabled connection factory (the default weblogic XA connection factory). Proxy service calls a business service which is based on the SAP JCA WSDL and posts an IDOC to SAP system. A Route to node with Routing option Quality of service set as Exactly Once is used to ensure a rollback in case of errors on SAP processing. (Also tried with a service callout in request pipeline to achieve the same result).
Here are the issues we are facing
1. If the the SAP Outbound connection on iwafjca resource adapter is set as Local Transaction
When testing from console the service runs fine. When message is sent from JMS queue we get an error "Transaction already exists". This seems correct as SAP Adapter will try to create a new transaction which will be possible while running from console while when Global transaction is created by JMS queue (when Proxy picked up message from XA enabled queue) SAP Adapter will not be able to create a separate transaction being not a part of XA.
2. If SAP Outbound connection on iwafjca resource adapter is set as XA Transaction
Even the business service when tested directly from console fails in this scenario. The error we get is "XA transaction not supported by JCA adapter".
Any idea how to make the SAP JCA Adapter call a part of global transaction so that failed messages can roll back to the JMS queue?
Sorry for the long description but I thought it will make it easier :)

Any idea how to make the SAP JCA Adapter call a part of global transaction so that failed messages can roll back to the JMS queue?The interface provided by SAP (SAP JCO) doesn't support JTA transactions.So there is no way adapter/Connection factory can enlist in global transaction.

This is known behavior and If I remember correct there is Bug raised but closed as Work as Designed (I still don't have clear explanation why adapter starts local transaction when underlying connection doesn't even participate ). Solution for this is to Make QOS=Best Effort.This makes sure that the local transaction required by adapter will not conflict with global transaction.
So if you expecting adapter to participate in global JTA currently it is not supported.

Issue with SAP PI FTP Adapter

Hi All,
We are seeing an issue with the FTP Adapter Communication Channel in SAP PI 7.1. When the communication channel is connecting to a FTP Server and if the connection request timeout ( ex: SFTP Server down ) we see a connection error .
However the overall communciation channel status doesnot refelct it and it is still in GREEN status. The status being wrong doesnt raise an adapter CCMS alert. Also we are seeing that the communication channel stops all connection attempts after the failure for that communication channel.
Wanted to check if anyone has seen or encountered the issue and how did you get past the problem.
Thanks in advance..
Arunava

Hi,
Could you please let me know whether it is sender communication channel or receiver ?
Also please check below.
1. Java messaging system queues are free or hanged ?
2. Please mention time out paramter in the channel.
3. Did you try Start/Stop the channel.
Please get back to me.
Regards,
Sachin

Issue with Receiver SOAP adapter for synchronous scenario

Hello All,
We are facing a strange issue with the SOAP adapter in the interface we have setup. This is the 1st time we are using SOAP adapter in our system (PI 7.11 SP7). We are making a synchronous HTTP call to the web service exposed by another system in our landscape. The payload is send with SOAP envelope and there are no credentials to be maintained in PI settings.
The issue is that we are always getting timeout exception in PI audit logs after sending the request (3 minutes - standard timeout value, no additional config for this). But target system has confirmed that they are sending the response back. We tested from our server OS level and have received the response back in the same screen (to verify there is no firewall/port issue in between the systems). But when tried from RWB, it is always giving the timeout exception and we are not able to see any other log.
We have tried checking in the NWA logs as well after increasing the logging level to ALL for com.sap.aii.adapter.soap. But surprisingly, we didn't get any logs at all for the outgoing SOAP call or incoming response and hence we are unable to trace the issue.
We have setup another synchronous inbound SOAP interface (PI exposing the webservice) and it is working fine. We are also able to trace the logs in both audit log and NWA logs.
Is there anywhere else we can check for the logs? Audit logs is showing timeout error and we are not able to see anything in NWA logs.
Does the target system need to maintain PI credentials in the header when they send the synchronous response back?
Are there any specific settings which should be checked to enable the sync communication? (this should not be the case since the inbound interface is working fine)
Please help.
Thanks
Justin

Hi Amit,
Thanks for the reply.
Yes we had tested successfully via SOAP UI as well (forgot to mention that). We are getting back the expected response in SOAP UI without using any credentials. We got the same response when we tested it through OS commands from PI server.
The WS is hosted by the target system and they haven't maintained any credentials at their end. So when PI is trying to access, we don't need to provide any credentials. My question is, whether the target system should keep any credentials to send the synchronous response back to PI (java stack). We have tried that as well but since there aren't any logs, we are unable to verify whether the credentials are coming correctly.
The service interfaces are correct and PI configuration are OK. I will try the XPI inspector for logs as you have suggested.
Thanks
Justin

Performance issues with SAP BPC 7.0/7.5 (SP06, 07, 08) NW

Hi Experts
There are some performance issues with SAP BPC 7.5/7.0 NW, users are saying they are not getting data or there are some issues while getting data from R/3 system or ECC 6.0. Then what things do I need to consider to check, such as what DataSources or Cubes I need to check? So, how to solve this issue?
What things I need to consider for SAP NW BI 7.0 u2013 SAP BPC 7.5 NW (SP06, 07, 08) Implementation?
Your help is greatly appreciated.
Regards,
Qadeer

Hi,
New SP was released in February, and now most of the new bugs should been caught ,This has a Central Note. For SP06 it's Note 1527325 - Planning and Consolidation 7.5 SP06 NetWeaver Central Note to fix any issues. Most of the improvements in SP06 were related to performance, especially when logging on from the BPC clients.There you should be able to find a big list of fixes/improvements and Notes that describe those. Some of the Notes even have test description how to reproduce that issue in the old version.
hope this will help you

BW Analyzer 3.x issue with SAP 7.1 Gui

BW Analyzer 3.x issue with SAP 7.1 Gui
After executing a BW worksheet and then "Selecting Filter Value" on a free Characteristic, The "Select Filter Value" Window pops up, but when you add or remove a characteristic it pops back to its original position. If you try a second time, the characteristic will stay, but when you click "OK" to re-execute the report the "Select Filter Value"Window does not close.
When you try to close the "Select Filter Value" Window, Excel error out and shuts down

Have you looked at OSS Notes. This may just be a 3.5 Analyzer ith a BI 70 server issue, or did this only begin to happen with a upgrade to e 7.10 gui?
The whole area of filters and variables with 3.5 Analyzer with BI 7.0 server has been shaky, so I'd look for Notes before I go down any reinstallion path.

Issue with JMS inbound Adapter and Asynchronous BPEL

Hi Gurus,
I am facing the below issue with JMS inbound Adapter and Asynchronous BPEL .
I have 2 JMS Queues one inbound and one outbound . The Composite has multiple BPEL Components around 4 on an average and i have 4 composites similar to that .
Totally 4 Composites * 4 BPEL Components = 16 Services
Propoesd Solution :
I have used MessageSelector in the JMS Adapter for selecting the incoming message. The BPEL gets invoked if the message selector is true and proceses the Message and writes the response to the other Queue.
Initially i had no problems but intermittantly the BPEL processes are getting invoked but they are not processing the data ( Bpel process is supposed to invoke an external service and get the response in a sync call) and each BPEL processe instance is in running state for ever . This remains even if i restart the servers .
The message gets read by the JMS Adapter , BPEL instace gets created but it wont proceed futher and remains in the runnign state for ever.
If i redeploy the Composite then messages get processed but the issue creeps up again ( i tried to checl the logs but ino cluea about the issue .
Getting frustrated day by day tried the bpel.config.transaction, increased the JMS Adapter threads , inreased the worker threads but all in vein..
please let me know if any one has faced similar issue .
Anticipating a quick response from the gurus.
Lakshmi.

We are also facing this issue in 11.1.1.5.
Breifly the issue is : The BPEL process which polls an inbound JMSAdater ( consume_message) either stays in running state forever ( whatever we do) or go to the recovery queue. It doesnt recover even if i try to recover it. This happens intermittently. Redeploying the application / restarting servers sometime solve the issue but as know we cant do that on prod systems .
Can some one look into this on priority and help us giving a solution/workaround.

Issues with Seeburger FTP adapter

Can one of you with Seeburger FTP adapter experience share some information on these issues I'm facing
1. Do I need to setup resource management in Seeburger workbench. If so, do I need to configure, resource, server and reservations. Do you have more information and what parameters I need here.
2. In the Seebuger FTP adapter, I have
Module Key - exit
Parameter Name - JNDIName
Paramter Valu - deployedAdapters/SeeXIFTP/shareable/SeeXIFTP
JNDIName, should I be replacing this with some other name. I'm trying to get Seeburger FTP to work and in the messaging monitor, I see the message as passed to Module Processor but it does go anywhere from there.
Can one you throw some light on this subject...what to expect from this definition.
Thank you for all your replies,
Parimala

I'm resending this since I did not have any luck with it the first time.
We also have an oss note waiting to be responded on this subject.
When I send messages using Seebuger FTP adapter, I see the following information in the SAP message monitor -
"Message entered module processor exit bean and will be transferred to JCA adapter".
But does not get to IBM VAN mailbox. How do I trace from this point onwards.
Should I use Seeburger monitoring tool for this? If so, I don't see anything in Seeburger monitoring (used all criteria).
Please let me know if you have any information on this subject.
Thanks,

SAP Sourcing 7.0 integration with SAP ERP - issue with SAP PI

Hi All,
We are integrating SAP Sourcing 7.0 with SAP ERP 6.0 with SAP PI 7.1 in middle. So the Sourcing will talk to PI and this intern will talk to ERP. Sourcing is on oracle 11g where as PI and ERP are on SQL 2008. All these 3 are on windows 2003 x64.
We are following the "Configuration Guide Integration of SAP ERP and SAP Sourcing 7.0" provided by SAP.
We have successfully configured Sourcing and PI systems as pe the document. In Sourcing, by using background jobs we are able to successfully generate files in "export" folder which is part of FTP directory.
However the issue is with PI, we configured the "configuration scenerio" in Integration builder and point all channels to the FTP folder in Sourcing. But PI is not picking up these files.
Is there any way to trigger this in PI system. Or do we need to do anything in sourcing itself.
Regards,
Siva.

Hello Siva,
I am thinking that you may need to deploy FTP adapter in PI to get this process work fine but not sure.
Let's see what other experts suggest.
Thanks,

Unreleashed segment issue with SAP schema

Hi All,
We are trying to generate SAP schema in BizTalk 2010 and facing unreleased segment issue and discussed with SAP team whom suggested below ways. We were interacted with MSFT and no hotfix yet. Please guide me.
The provider/external should call IDOCTYPE_READ_COMPLETE in the following way:
- PI_RELEASE = ' ' => last existing segment version is returned
- PI_RELEASE not available in the interface => last released version
Which means: BizTalk needs to ensure the PI_RELEASE is not present in the call of the interface. This will allow pulling the last release version of the IDoc including not released segments.
Thanks, Raja MCTS BizTalk Server 2010, MCC If this answers your question please mark it accordingly

BizTalk does not support unreleased segments for Receive Operations.
As far as I know SAP 'locks' the segment types that have not been released and the LOB adapter of BizTalk cannot properly read those segments.
The SAP team should set a release on the IDOC types and segments you need.

Issue with SAP Single Sign-On and Scheduling Reports

Hello --
We are on XI 3.1 with SAP BW and SSO. Some users are getting failures with this error message when they schedule a report to run:
"A database error occured. The database error text is: Unable to connect to SAP BW server System received an expired SSO ticket. (WIS 10901)."
It SEEMS as though the users are fine if they schedule the report to run immediately and have it run every hour (or less) after that. If they schedule it to run several hours from the time they are in the system, however, it looks like they begin getting failures around 8 hours after they were in the system. This would make sense from looking at the "InfoView and Central Management Console Session Management" document (https://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/405547f9-b840-2b10-44b5-8e17ff9e48a9&overridelayout=true) since a logon token expires after 8 hours, but since it is a scheduled report, and the user is not logged in through a browser, how is a token being passed? Is it captured and included when the report is scheduled? Would disabling logon tokens fix this issue? How is authentication handled here if they are disabled?
Thanks for any info
Casey

Hi Gurus
I am facing the exact same error.
However, we are not trying to schedule the WEBI report.
The user gets this error even when he is running on demand from the portal.
Here are the various steps tha twe have tried and still it doesnt work:
1) Refreshed and created new Universe connection
2) Bounced BOE server
3) Synced up the SSO timeout ticket to 8 hrs on all systems including BOE
4) Changed browsers
5) Removed cache, cookies etc
Please help.

Issues with signal input adaptive filtering, it won't filter the added noise from the input waveform

Hello,
I have an issue with my adaptive noise cancellation program. Essentially I want to input a custom wav add noise to it and then filter the noise away in order to gain the custom wav again.
While doing so I want to read the learning curve and read the adaptive coefficients. Unfortunately I have an issue when it comes to the filtering of the custom wav+noise. It won't filter the signal at all.
It would be helpful if someone could have a look at it and possibly help me out.
Thanks!

Hey Jan,
Thanks for the reply. I am currently using the Adaptive Filter Toolkit in order to obtain those VIs. The VIs which are in use are the LMS Adaptive Filter ones.
I figured there might be an error with the input of the array. This VI requires a DBL Array but it seems like it can not process it.
The "Get Wavefirn Components" works better now but I still have an issue with a time. I put a 9s wav file in but it only computes it in a very short time and I can not play the file while it is computing.
I added the modified program to the attachments.
This program is ought to read a waveform file add noise to it and then use an adaptive filter in order to get the orginal waveform back again and if possible either store or play the final waveform.
Thanks for your help.

Issue with HAL essbase adapter

Hi Experts
I have an issue with HAL,I got the below error when I tried to use essbase adapter, the HAL version is 7
java.Lang.NoClassDefFoundError
I know this is known error ...most of the forums are telling this is error related to Environment Variables...but I dont know how to fix as I am unaware of this....java..... classes..bla bla bla..
I installed HAL in c drive, Can anyone help me ...how to fix this issue....
Thank You
M.S

Go to control panel->system->system properties->advance->environmental variables. You should have something like this "C:\Program Files\Vignette\V7\vbis\Hyperion\EssbaseAdapter" in your classpath variable. Check you installation on your "C:\" drive to get the correct path. Hope this helps.

No accounts showed up after running reconcillatio with SAP HR adapter

Good afternoon all,
I have an urgent question with the SAP HR adapter and I cannot resolve it for three days. You help will be greatly appreciated.
I configured SAP JCO 2.1.9 to work with IDM 8.1 SAP HR adapter. The "Test Configuration" button works on the first page of SAP HR Resource Wizard. After I ran a full reconcillation, IDM gave a status "Full reconcillation succeeded" with the following details:
Users examined for claims 0
Resource accounts claimed: 0
Resource accounts discovered: 8578
Native changes detected:
Accounts added: 8578
Accounts processed for reconcillation: 8578
Correlation processing:
Resource accounts fetched: 8578
Accounts correlated with users: 8578
Account state updates required: 8578
To see the account index for the accounts in each category, click a situation type below:
While the account index search returns nothing and listing accounts shows no accounts from SAP.
Would you please shed some lights on what might be wrong with my configuration? Thank you very much for your help.

Did you find any solution? I´m facing a similar problem: when I run the reconciliation in a few secons it ends and shows 0 for all kind of results (claims, discovered, fetched,...). In another instance it works fine so we configured this SAP resource in a similar way but doesn´t detect accounts.
Regards.
