Adapter Engine handling for CDATA in XML

Gurus:
I had a question on the Dapter Engines behavious, specifically the SOAP Sender.
The Source is sending something like:
<Data><![CDATA[<?xml version="1.0" encoding="ISO-8859-1" ?><response><forms><form ObjectId="4070" Form_Name="P40 Action"><EMP_NAME>Howard Roark</EMP_NAME><PERNR>P1111111</PERNR><WORKAUTH></WORKAUTH><HR_NAME>Scott Manager</HR_NAME><HR_PNUM>P1234567</HR_PNUM><ESIG>Scott Manager</ESIG><ELECTRONIC_SIGNATURE>Scott Manager (electronically signed)</ELECTRONIC_SIGNATURE><ESIG_VERIFICATION>Scott.Manager [Tue Jun 2 12:03:56 EDT 2009]</ESIG_VERIFICATION><ESIG_DATE>06/02/2009</ESIG_DATE></form></forms></response>]]></Data>
</GetFormXMLResult>
What the Integration Engine sees is the Data elelment with the CDATA section trimmed, i.e., it sees:
<Data> <?xml version="1.0" encoding="ISO-8859-1" ?><response><forms><form ObjectId="4070" Form_Name="P40 Action"><EMP_NAME>Howard Roark</EMP_NAME><PERNR>P1111111</PERNR><WORKAUTH></WORKAUTH><HR_NAME>Scott Manager</HR_NAME><HR_PNUM>P1234567</HR_PNUM><ESIG>Scott Manager</ESIG><ELECTRONIC_SIGNATURE>Scott Manager (electronically signed)</ELECTRONIC_SIGNATURE><ESIG_VERIFICATION>Scott.Manager [Tue Jun 2 12:03:56 EDT 2009]</ESIG_VERIFICATION><ESIG_DATE>06/02/2009</ESIG_DATE></form></forms></response> </Data>
Is this an issue with the Aapter Engine, or has anyone come accross this before? This is on PI7.0 SPS 13.
Thanks
Feroz

Hi,
the CDATA section should not be a problem. It's mostly used to include information / XML in one tag and to include special characters that should not be changed or ignored by the system. All informaiton within a CDATA element is ignored by PI and handled as "blackbox" string. PI just receives it and passes it out without really looking what's inside the tag.
If you want to extract what's inside the CDATA element, you need to use an XSLT in your mapping (see: Handling CDATA in PI)

Adapter Engine Prioritation for JDBC Adapter

Hi ,
I am currently working on an Idoc to Jdbc Scenario. The jdbc adapter is used to push the messages to three different legacy systems through three different scenarios. I need to prioratize the messages of the legacy systems(For Eg. Legacy System A is more critical than Legacy System B) in adapter engine or in adapter itself.
Regards,
UserPI

Hi
We are having the same problem. Once one of the interfaces which is using a JDBC communication channel is processing a bigger amount of messages, the JDBC adapter seems to be blocked exclusively for that interface. All other interfaces using the JDBC adapter are on hold (status "Scheduled" in Adapter Engine Message Monitoring). I set up message prioritization in RWB (Component: Adapter Engine), but it doesn't help (nothing different from before).
Does anybody has a hint on that?
Thanks

File Adapter Fault Handling for CSV files

9iAS WE v2 Beta: which adapter to use for BC4J-UIX-XML components?

hi,
through official TAR i still have no answer after 3 weeks, so maybe someone here can help me out.
using Jdveloper 9i RC i create a BC4J-based client project (BC4J-UIX-XML components) which i want to use for wireless services. the only thing i know is that oracle recommends this framework. together with WE v2 we got more than 1000 pages of documentation, but nothing about the new adapters (the most important thing i believe, what else am i supposed to do as official beta tester?!!).
any piece of information about the new adapters (especially the oc4j-adapter) or any kind of examples are really appreciated.
TIA, trevi

automatic mode is just for quick demos. You cannot internationalize your application while using automatic mode.
You will need to turn off automatic mode, and have bc4j:column beans in your table and databind the data to come from your resource bundles.

Adapter engine payload

Hi
In my XI system I am able to see the Adapter engine payload for asynchronous messages.
But it is not showing the payload for synchronous messages. Where can I change the settings
so that I can see the payload for synchronous messages too.......?? Meanwhile in case of
asynchronous messages my XI system is asking for saving the payload rather to displaying the
message in the window itself. Where can I change the settings so that it won't ask for saving
the payload ??
thanks
kumar

Hi,
You will be only able to see Asynchronous messages in Adapter Engine and not the Synchronous messages.
For Synchronous message logs you need to login to SAP ABAP stack, TCode sxmb_adm -> Integration Engine Configuration -> Specific Configuration
Edit and Add new Entry with following details
Category: RUNTIME
Parameters: LOGGING_SYNC
Current Value: 1
Regarding your second query, can you tell the exact page from where you are trying to see the payload. It should show the payload in the window only. I don't think there is some setting for this in XI.
Thanks
Amit

Cache Refresh for Adapter Engine is not working

Hi,
our adaper engine is not working. At RTW no there are no channels visible and the button "Test Cache Connectivity" leads to a yellow icon for the adapter engine with the error text: "Attempt to fetch cache data from Integration Directory not yet started or still in process".
The error reason is at <i>http://<j2ee host>:<port>/CPACache/history.jsp</i> available: <i>com.sap.aii.af.service.cpa.impl.exception.CPADirectoryCacheException: Couldn't open Directory URL (http://pixd1.digoff.no:55200/dir/hmi_cache_refresh_service/ext?method=CacheRefresh&mode=C&consumer=af.xd1.dat-dof-xi), due to: HTTP 403: Forbidden</i>
<b>The cache refreh request from adapter engine to directory gets an 403 error.</b> What is strange: No problem, to execute that request in a browser, i get the right message, no fault.
I searched for notes or other threads, i could find only <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_bc_xi/~form/handler%7b5f4150503d3030323030363832353030303030303031393732265f4556454e543d444953504c4159265f4e4e554d3d373531383536%7d">SAP note 751856</a> , but it is valid for XI 3.0; we are on PI 7.0.
I checked out:
- no user blocked
- all system users have standard authorisations
- reimport of SAP BASIS SWC
- SICF services for XI active
- destination INTEGRATION_DIRECTORY_HMI working
Any idea, how i can get the adapter engine working?
Regards,
Udo

Hi,
There are two ways to display the content of the CPA cache refresh.
1. The Cache-Update Content-XML
Document can be stored in the Adapter Framework database (J2EE schema) for further analysis. Here you have to set the property in the J2EE Visual Administrator tool.
To do so, proceed as follows:
=>J2EE-service SAP XI AF CPA Cache
=> set property trackCacheUpdateXML= true
=> You can now display the cache update XML with the alias CPACache
=> View Cache Update History
=> View Cache Update XML
2. The content of the cache refresh from the Integration Directory intothe CPA cache can be written to an XML file: Here you have to set the property inthe J2EE Visual Administrator tool:
=>J2EE-service SAP XI AF CPA Cache
=> set property J2EE service SAP XI AF CPA Cache cacheUpdateDebugFile = true
=> the CPA cache refresh XML file will be in the server(0) directory search for the following file names:
=> value of the property cacheUpdateDebugFile.deltaif you intend to see the delta refresh accordingly and the value of the property cacheUpdateDebugFile.full if
you intend to see the full cache refresh content
Note: After your analysis, do not forget to reset the properties value to false.
You can delete the XML cache-
refresh table: alias CPACache
=> View Cache Update History
=> Delete History
Also check out the user and its permission.

HI..
Have a look at this blog :
3) Error: HTTP_RESP_STATUS_CODE_NOT_OK 401 Unauthorized
Description: The request requires user authentication
Possible Tips:
u2022 Check XIAPPLUSER is having this Role -SAP_XI_APPL_SERV_USER
u2022 If the error is in XI Adapter, then your port entry should J2EE port 5<System no>
u2022 If the error is in Adapter Engine
u2013then have a look into SAP note- 821026, Delete the Adapter Engine cache in transaction SXI_CACHE Goto --> Cache.
u2022 May be wrong password for user XIISUSER
u2022 May be wrong password for user XIAFUSER
u2013 for this Check the Exchange Profile and transaction SU01, try to reset the password -Restart the J2EE Engine to activate changes in the Exchange Profile After doing this, you can restart the message

Hi,
we have to explicitly mention batch while configuaring file adapter.
i.e. in step 5 : Check file contains multiple messages and mention how many messages u want to process in a batch.
i.e. if you have 10000 msgs in ur file mention the size as 500. Then it will read 10000 records in 20 batches.
Now while writing to a file use Append=true property.
U have to add this property to fileadapter.wsdl (in jca:operation tag) which will be created when u complete the configuaration of file adapter with write operation.

How to get Alerts mail for adapter engine errors in SAP PI 7.0

Hi Friends,
I configured Alerts in PI 7.0. with the help of t-code u2018ALRTCATDEF and created a new alert catergory.
In container tab i have mentioned all give below elements.
SXMS_MSG_GUID, SXMS_RULE_NAME, SXMS_ERROR_CAT, SXMS_ERROR_CODE, SXMS_FROM_PARTY, SXMS_FROM_SERVICE, SXMS_FROM_NAMESPACE, SXMS_FROM_INTERFACE, SXMS_TO_PARTY, SXMS_TO_SERVICE, SXMS_TO_NAMESPACE,SXMS_TO_INTERFACE
I am getting alerts when I manually test the alerts configurations by running the report u2018RSALERTTESTu2019.
I am getting mail as :
Alert ID: ##00009##
Dear Administrator,
This is with respect to XI Scenario. During processing of XML file from ECC or XYZ Server, Following error has been occured:

NOTE: To check the file name, go to SXMB_MONI and search for above message ID.
Double click on that message ID and click on error in left hand tree.
Please take appropriate action in co-ordination with respective functional and BASIS consultant.
But When I am getting a error , I am not getting an alert mail. Right now iam doing in XI Development.
I am not getting an Alert mail , when my message is in status of : System Error . Error catergory is : XI_J2EE_ADAPTER_JDBC.
Kindly tell how to get alert mail for error catergory : XI_J2EE_ADAPTER_JDBC and in Adapter engine errors.
How to get alert mail when my message is failed with any reason in Adapter engine.
Waiting for quick replay. Please help me out.

Hi thanks for quick reply.
As per your given link : http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/14877. [original link is broken]
I have done all these steps. But still little problem.

Message split on adapter engine for the java based IDoc adapter

Hi Guys,
Do you know if message split on adapter engine is available for the java based IDoc adapter on the single stack (PI 7.31)?
I'm getting such exception when I try to post 3 IDocs
Transmitting the message to endpoint <local> using connection File_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.idoc.exception.IDOCAdapterException: Error before sending due to idoc parsing error: (7) IDOC_ERROR_PARSE_FAILURE: Invalid XML 1.0 character encountered within IDocXML for type <ns0:Messages>:

sourceSnippet=...UTF-8" standalone="no"?><ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge"><ns0:Message1><...
^
Mapping is one to many.
Each IDoc content has been compared manually against the xsd schema and it was fine.
I know that old way of modifying xsd is still possible.
Best regards,

Did you find a solution to this? Having a similar error right now.
Thanks and kind regards

Adapter Engine XML Schema Validation Error Surpression

We recently developed a number of web services that are called by 3rd parties outside our network. The web service request once made is picked up by a Web Dispatcher which then forwards the request to the de-central adapter. Both of these components reside within within a DMZ.
We have, as an additional security measure made use of the new Adapter Engine XML Schema validation available with PI 7.1, to ensure that the payload of incomming messages is checked to ensure that it is a known structure.
Now here is my problem, we recently had these services penetration tested by a 3rd party to ensure that they were secure and whilst the report was very good showing no major weaknesses they did pickup on a couple of items including that the fact that if the XSD to be used during payload message validation cannot be found an 'ADAPTER.JAVA_EXCEPTION' is returned to the web service consumer that highlights the path details of where the XSD should be (but could not be found).
This was viewed as useful to an attacker for a number of reasons:
1. Feedback in SQL injection attempts via verbatim DB error messages greatly improves attacker efficiency
2. Path information is useful to the attacker for OS fingerprinting, directory traversal attempts
3. Other miscellaneous stack trace information is useful to an attacker to understand how the application works
Is there anyway this can be surpressed so that the adapter does not show this information in the returned error message - see example message below ?

Hi,
We are having the same problem, so you are not alone.
I had an extensive call with Azure premium support and we where able to determine that:
- Nothing is missing or in the wrong place in my exported .xml file.
- Any changes to the VNET's using the web gui interface of https://manage.windowsazure.com is not possible when you have dns servers and use an gateway
- You can download the .xml configuration file of the network and make manual changes to it, then import it again , to add/remove dns servers and or subnet's.
I am currently waiting for an solution, i have let them lower the urgency from A to B (because i can make changes trough xml) and responded to the next support contact (saying he will continue with the issue) that the problems seems to be with azure and
he should speak with the previous person helping me. I have not heard from Azure support since.

I hope microsoft is going to resolve this soon, as i do not want to edit my xml for little things like adding a subnet all the time. I have requested an status update in the issue.
Should anyone have more information on this, please share it here.

What is the max file size that a Adapter Engine [J2SE] can handle ?

We are having a scenario where a 4 GB compressed file needs to be sent across without mapping, I'm trying to explore the possible options to tackle this scenario.
Some of the options, we are considering :
- Sending a file from one Adapter Engine [J2SE] to another Adapter Engine [J2SE] bypassing PI. Adapter Logs will be monitored. What is the maximum file size that can be then handled assuming a standard installation ?
- What is the max file size that Adapter Engine [J2SE] can send through PI without mapping?
Any help with the above options or with any other possible solutions to handle extremely large file transfers will be much appreciated.

Hi,
j2se is not a good option here
if you have 4gb then you need a copy solution
a) build an proxy that will just copy the file from sender dest to receiver
b) build an adapter that will do the same as proxy)
this way processing of this message will be controlled with SAP PI/XI
it will be as quick as copy & paste of the 4gb file
I did the a) for one of the flow for 300 mb and it works perfectly

It looks like the adapter engine is not able to register him self on SLD, you have to check in the SLD the "Exchange Infrastructure" domain, you have to verify restarting the J2EE the adapter engine update the entries in the SLD related to the specific XI Domain.
Launch Visual Administrator >> Server >> Services >> SAP AF CPA Cache
Enter the appropriate values for:
SLD.selfregistration.hostname (Use fully qualified hostname)
SLD.selfregistration.httpPort
SLD.selfregistration.httpsPort
