OSB: MTOM and OWSM policies together

Hi,
I've set up a proxy chain, that invokes business service, that invokes soapUI mock.
The mock return a file. All services are set up with MTOM pass by reference.
It works like a charm. I receive my file as ctx:binary-content element.
I have to add an OWSM policy to a business service. I've picked the simplest one, oracle/log_policy.
Now the problem occurs. The business service returns:
[OSB Security:387009]Failed to convert message context to SOAPMessage
com.bea.wli.sb.context.BindingLayerException: Decoding of MIME attachments from MIME Content-Transfer-Encoding='7bit' not supportedDo you have any idea what's going on?
Additonal question: is there a living soul which has been able to set up OWSM policies ant MTOM together?

I got this to work by switching "WSDL definition" from binding to port. Why would that help?

How to install OSB, ADF and BI Bublisher together on WLS?

Hi,
We have to install OSB, ADF, BI Bublisher and the Oracle Service Registry together on an Oracle Weblogic Server. We have tried different strategies regarding the order to install the
components in and the number of domains, but are struggling with getting it to work.
There must be a best practice for the order to install the components in and a preferred way to distributed the components in domains. We have not found any documentation that describe
this.
Can anybody help?
Here are the versions of the components:
- WLS 10.3.0.0
- OSB 10gR3
- ADF The one that comes with JDeveloper 11.1.1.0.1
- BI Publisher 10.1.3.4.0
- Oracle Service Registry 10.3.0.0

[OSB and OWSM] - External Web service stacks and frameworks

Hi everyone ! I'm starting to read about OSB and OWSM and I'm having some doubts. I've some developments of Web services with external Stacks like CXF, JBossWS, Metro and I'd like to ask some questions:
1- Will I be able to productively leverage all features of OSB and OWSM like creating a proxy service to add WS-* standards policies and features (WS-Security, for instance) even with these web services implemented in different stacks other than Weblogic's ?
2- If it is possible, do these web services need to be deployed at the Weblogic server to enable the OWSM and OSB to work effectively ?
3- Even if it is possible to use the OSB and OWSM nicely with webservices developed at external stacks and deployed at other application servers is there any reason to quit using these external web service stacks in favor of Weblogic's (like features only enabled on OSB/OWSM when the services use the Weblogic stack) ?
I suppose that if I ignore the JAX-WS stack from Weblogic and use an external framework (like CXF) I'll lose most of the application server administration capabilities since the Weblogic server won't be able to recognize the CXF stack as it does with its own.But, the main doubt I'm in is, since OSB and OWSM might be used with external providers I probably won't need to develop my web services using the Weblogic implementation (which my team does not yet know) since there will be no features of the OSB and OWSM which can only be used with the Weblogic's stack. I would like, please, to know your oppinions about these considerations. Sorry about the long post and possible errors (I just started learning).
Thank you!

Hi Lupan,
I can speak mostly to OWSM as my experience with OSB is small thus far.
+1- Will I be able to productively leverage all features of OSB and OWSM like creating a proxy service to add WS-* standards policies and features (WS-Security, for instance) even with these web services implemented in different stacks other than Weblogic's ?+
OWSM (10gR3) has two types of policy enforcement point (PEP) -- Gateway and Agent. The Gateway acts as a remote proxy and is neutral to the service implementation technology as long as it adheres to SOAP 1.1. In this regard you can use OWSM freely with CXF, MS implementations, etc. Agents run in-process with the service and thus have far greater restrictions on what service implementation frameworks and containers that are supported. There is some certification for AXIS 1.x running in OAS and Tomcat; but practically speaking, my recommendation for Agents is to only use within OAS 10gR3 where it is built in (and using OC4J Web Services through JAX-RPC).
OWSM 11gR1 initially supports only agent-style (in process) PEP and is built-in to Fusion Middleware and WLS. It is only for Fusion and WLS Web Service implementations.
OWSM is quite full-featured for WS-*.
+2- If it is possible, do these web services need to be deployed at the Weblogic server to enable the OWSM and OSB to work effectively ?+
"No" if using OWSM Gateway PEP. A qualified "Yes" if using OWSM Agent PEP.
+3- Even if it is possible to use the OSB and OWSM nicely with webservices developed at external stacks and deployed at other application servers is there any reason to quit using these external web service stacks in favor of Weblogic's (like features only enabled on OSB/OWSM when the services use the Weblogic stack) ?+
There is the manageability that you mention, but also there is the identity propagation scenario and tight security integration. Both OAS and WLS hosted services in the native stacks (JAX-RPC and JAX-WS) allow sophisticated and secure passing of identity in the request -- for instance, via SAML Assertions in the WS-Sec header -- and built-in capabilities to map the passed identity into the running service's Subject (i.e. enabling JAAS security etc.).
In my experience this type of identity propagation functionality has either been absent or less complete in other typical implementation frameworks not closely aligned with the container security mechanisms.
Hope this helps,
Todd

OWSM 11g : Authentication Providers for X.509 and SAML policies

Hi All,
I am currently trying to implement the X.509 and SAML policies. As per the documentation for these polices I need to configure an authentication provider(or Identity Assertion provider) that can handle perimeter authentication via the NameCallback. I had configured an authentication provider(default authentication provider) that handled the namecallback and passwordcallback. What I can't figure out is how do these two authentication providers differs. And, incase one has to configure for the X.509 and SAML policies how to do the same.
Any pointers will be useful. Especially, from anyone who has worked and implemented the above policies.
Thanks in advance.

After research by Oracle Support it actually turns out that this problem was a combination of factors:
1) some clients were effectively using an invalid certificate so it is corrrect they got an error and everything worked fine when they started using the right certificate
2) it does, however, turn out that, in the case of an error the error handling has been obfuscated in WLS 10.3.6 as compared to WLS 10.3.4 which gives a more descriptive error stating the nature of the problem (missing certificate, invalid certificate, unknown user, ...). Apparently this was deemed a security issue and has thus been replaced by a generic "internal server error". It is however possible to re-activate this older behaviour using a couple of JAVA_OPTS that you pass during server startup:
-Dweblogic.wsee.security.debug=true -Dweblogic.wsee.security.verbose=true
The above reintroduced the behaviour we had in WLS 10.3.4 and thus solves our problem!

Seeking recommendations for handling large binary documents with security(preferable) for inbound and outbound scenarios from OSB- SOA and SOA- OSB

Hi,
I am currently working on a project with the following requirements
1. Client transfers binary document (between 1-20MB in size) from OSB proxy to SOA composite to Content Management system
2. Client retrieves binary document (between 1-20MB in size) from Content Management system to SOA composite to OSB proxy
In otherwords, a inbound and outbound integration.
What I have tried so far and my results:
Scenario A
1. Enabled MTOM on SOA composite by attaching wsmtom policy
2. Created an OSB business service and consumed the SOA composite application
3. Enabled MTOM on OSB proxy and business service and configured it to pass by reference
Scenario B
1. Enabled MTOM and security on SOA composite by attaching wsmtom policy and SAML policy
2. Created an OSB business service and consumed the SOA composite application
3. Enabled MTOM on OSB proxy and business service and configured it to pass by reference
I have a demo integration setup that writes a binary document to a file using the above steps. My SOA composite has a file adapter that writes the binary data to an external file and it is exposed as a web service with a simple WSDL definition that has an inline XSD schema with an single element of base64binary type. I have added a mediator that maps this base64binary element node to the file adapter's input node.
Result for Scenario A with file size less than 1 MB:
Flawless execution with sub-second response times
Result for Scenario A with file size of 8MB
First attempt: SOA composite faults with database transaction related error, solved by increasing JTA timeout
Second attempt: Flawless execution, but file transfer took over 100 seconds to complete. This is very poor performance and my suspicions are that this cannot be the expected behaviour, but I dont know the internal workings of the SOA composite and why its taking this long.
Result for Scenario B:
The OSB business service does not accept/recognize the SAML policy in the WSDL and suggests to configure OWSM policies manually, but OWSM policy in OSB does not have the wsmtom policy. Regardless of this, any permutation of MTOM + WSS security in this integration scenario either did not work outright or MTOM optimization was not happening ie binary data was materalizing in the message body.
I have only about 3 weeks left to implement a viable solution and the closest ive come to a solution is Scenario A but that +100 second response time for an 8MB file is really worrying.
I would appreciate any level of guidance, recommendations or suggestions as to how I go about tackling this problem.
Thanks
regards,
Johnny

I think this is due to the underlying mechanism of weblogic classloading..
You can contact oracle support @ https://support.oracle.com to report issues. Roughly this is the process .
1- get the Oracle Customer Support Identifier (CSI) for the client you are working for.
2- Create a user profile quoting the CSI. This will send an approval request to oracle support admins at your client.
3- Get the oracle support admins at your client site to approve your request for support access.
4-Once they approve , you can access the support site and raise service requests.

Importing OWSM Policies in Eclipse

HI
We are using Oracle webserver 11g and We have a requirement of adding OWSM policies to the OSB and using Eclipse as our IDE .Please provide the step by step procedure to add the policies
Thanks in Advance

Hi,
http://download.oracle.com/docs/cd/E17904_01/doc.1111/e15866/owsm.htm#CHDEEGJI
Oracle Web Services Manager is a run-time component, attaching policies to Oracle Service Bus services requires a connection to an Oracle Service Bus domain that has >Oracle Web Services Manager enabled.
In Eclipse, when adding Oracle Web Services Manager policies to services, you must be connected to a running domain that has Oracle Web Services Manager enabled. If >you are not connected to a running server in the development environment, you can only view and remove previously added Oracle Web Services Manager policies, and >Oracle Service Bus shows a warning that the Oracle Web Services Manager policies will be validated only on publishTo attach OWSM policy in eclipse IDE , go to proxy service open policy tab, there is option to attach OWSM policy from OWSM store.

Best practice for OSB, OER and OSR

Hi,
I would like to know what are the best practices for using OSB, OER and OSR together in a run-time environment for a simple WSDL service.
From how I see it:
1) Create service-definition in OER
2) Create proxy and business service in OSB
3) Use harvester to harvest the proxy and business services in OER
4) Use Exchange Utility to publish the proxy service to OSR
Then the client and discover the proxy service and use OSB for invoking the operations from service.
Kindly correct me where I am wrong.
Some questions:
1) Do we ever publish business service to OSR? Or is it only meant for proxy services?
2) Is synching of OSB and OSR only meant when we are not using OER?
Looking forward...

Hi Anuj,
Thanks for the links, they have been helpful.
I understand now that OSR is only meant to contain only Proxy services. The synch facility is between OSR and OSB so that in case when you are not using OER, you can publish Proxy services to OSR from OSB. What I didn't understand was why there was a option to publish a Proxy service back to OSB and why it ended up as a Business service. From the link you provided, it mentioned that this case is for multi-domain OSBs, where one OSB wants to use the other OSB's service. It is clear now.
Some more questions:
1) In the design-time, in OER no Endpoints are generated for Proxy services. Then how do we publish our design-time services to OSR for testing purposes? What is the correct way of doing this?
Thanks,
Umar

OSB MTOM HTTP Streaming

Hello everybody,
I have just started using Service Bus 11gR1 and I run into a problem. I need to define a proxy service (web service) which accepts large files (hundreds of MB).
I opted for using MTOM/XOP combined with HTTP streaming. To do this, I enabled in the "Message Handling Configuration" screen, the "XOP/MTOM Support" option and I set "Page Attachments to Disk" to true.
Actually, when I try to send large messages, the memory usage does not increase because the binary sent is buffered into the disk. Now I noticed that, before the proxy server is called, the binary sent is saved in a temporary file. I was wondering whether or not we can define a limit on the Message Size to be checked*before* the file is buffered on the disk. I want OSB to start reading the HTTP streaming and, when the max size is reached, to reset the http connection with the client. If this is not possible, I think that this is an issue from a security point of view.
Thank you in advance.

I don't know the answer to your question. Sorry! But It sounds like you have more succes with mtom on OSB than me. So I have a question that I hope you can help me with. Is you service based on a WSDL? if it is, can I see how it looks because I have some problems, making a wsdlbased proxyservice with mtom and invoking it from soapui

ADF and OWSM

Hello,
I am new to OWSM . My scenario is that I have a BPEL with three adapters, deployed it to a standalone server, applied Authentication of SOA Composite Web Service with Log_Policy enforcement.So the Bpel prompts for userid and password that on being provided displays data well and fine. I then created an ADF application and then web service data control on the Model project, reused the WSDL of the previously deployed BPEL application. But my question is how do I implement the userid and pwd validation in the jspx pages i.e my requirement involves two input fields in the jspx page that take in inputs to implement the owsm policies.
Please help me in this regard. Also do paste any links available on the same topic.
Thanks

Hello Dana Singleterry ,
Yes I have done that. But I want to secure the web-services and implement the same from ADF . How do I do that?? Any clues??

OSB MTOM...

Hello everybody,
I am using Oracle Service Bus 10gR3. I need to define a proxy service (wsdl based web service) which accepts large files (attachments).
I am supposed to use MTOM/XOP combined with HTTP and I need to pass this request attachment to the backend using a Business Service. After googling I came to know that for this I need to enable the "XOP/MTOM Support" in the configuration settings for the proxy service. Still I am not sure about how to go for it.
Can anyone help me with a sample code for the same.
Thanks in advance.

MDS data source target on Admin server for owsm policies

Hi,
We have a clustered environment with admin and manage servers on two different physical machines.
Bust admin server doesnt have DB connectivity only manage server has DB access where owsm polcies lies.
Should admin server also have owsm policy access or is it fine if we have owsm pokicy access only on manage servers.
Actually when we try to deploy services having owsm policies through admin server, we are facing issues.
Thanks,
Sowmya

The issue was solved by resetting the Data Source's credentials.
I hope this helps to somebody else,

Command Spacebar opens Spotlight as you have found out. If you want to change languages you need to say what app you are using to write the story in, I'm guessing you are using Pages or MS Word. If that's the case
Pages: Open Inspector - Click the T tab - Click Language and change your language.

Perform static and dynamic check together on a customer?

Hello All,
Is it possible to perform static and dynamic check together on a customer?
I believe standard SAP does not allow both options together.
The scenario is: My client has customer who orders products 1 year in advance and create sales order with a future delivery date. The customer might have balance due on their account which is close to the credit limit. As a result the sale order should be blocked as if the automatic credit check is "Static". This would allow our customer service to call the customer and arrange for the payments.
Then 11 months later, a dynamic check should be performed on the customer to make sure the past due is under the credit limit. If the past due is over credit limit, the sales order must be blocked for delivery as if the credit check was "Dynamic" with 30 days horizon. This would again give our customer service time to settle the payment with the customer.
If anyone has implemented such a scenario, can you please give me an overview of how you did it?
Thanks very much in advance and Text Removed.
With Regards,
AM

Please dont include this text

Static and Dynamic Cannot be Performed together. They are mutually exclusive events.
Credit check can be performed either at Sale order level or at Delivery / PGI Level.
FCV3 is a good report to see whether a customer would fail a credit check. ( suitable for your customer service )
Coming to your Point , Assuming that the customer is eligible for a Credit of 50 Lacs. Now the Customer has placed an order for 60 Lacs. We set the Customer credit checking at order level . The Customers Sale order would get blocked.
The Customer service will follow up for the payment and see to it that it is made. Assume the customer has made a payment for 70 Lacs.
Now let us have a look at the account statement of the customer.
Account Statement : Customer Cr : 70 Lacs. Dr : 0. ( because no delivery and invoice so far has been made )
So we are supposed to deliver the Material worth value of 60 Lacs.
The First sale order worth 60 Lacs has been unblocked in VKM3. Now at the time of Delivery level why would you want to chekc the Credit limit again ? It has already passed the credit check.
It is not necessary to check credit limit . Because you have already performed the same at the order level.
Now the customer has come again and raised another sale order for 80 Lacs. The System would block him.
The system will never block the Previous delivery which you are, due for delivery to the customer.
If we keep on checking the Credits without delivering we would end up only raising in Sale orders and no Delivery to the Customer at all. The Debit side of his account will always be 0.
So i donot think Static and dynamic is needed . you can go for either Static or Dynamic.

NEW 9I RMAN: BACKUP OPTIMIZATION AND RETENTION POLICIES

제품 : RMAN
작성날짜 : 2004-05-20
NEW 9I RMAN: BACKUP OPTIMIZATION AND RETENTION POLICIES
=======================================================
오라클 9i RMAN 에서는 백업을 보다 효율적으로 할 수 있는 기능을 보강 했다.
지금 소개할 "Retention Policies" 기능을 통해서 보다 효율적인 RMAN 백업
전략을 세울 수 있다.
1. 백업 화일 최적화 방법 (Backup File Optimization)
백업 화일 최적화란 백업에 소요되는 공간을 최소화 하는 전략이다. RMAN
백업시에 같은 정보 (dbid, checkpoint, and resetlogs data 등등) 를 가지고 있는
화일이 이미 존재하는 백업 셋 내부에 있는지 체크하게 된다. 만일 같은 화일이
이미 백업 되어 있다면 BACK UP 명령은 해당 화일에 대해서는 백업을 하지 않게
된다.
이때 같은 화일이라고 판단하는 기준은 다음과 같다.
* Datafile: 같은 DBID, checkpoint SCN, resetlogs SCN 과 time. 데이타 화일은
반드시정상적으로 offline 되었거나, read-only 이거나, 또는 정상적 으로 close
되어야 함.
* Archived redo log: 같은 thread, sequence number, 그리고 같은 Resetlogs
SCN 과 time.
* Backup Set: 같은 Backup Set recid 와 stamp.
RMAN 이 백업을 수행하다가 위와 같은 조건의 화일이 이미 존재함을 확인하면
이것은 건너뛰게 될 화일의 대상이다. 하지만 이때 바로 Skip 을 결정하지 않고
정해진 Retention Policies 를 조사 한후에 Skip 여부를 결정 하게 된다.
만일 백업 명령에 DELETE INPUT option 이 사용되면 RMAN 은 백업이 Skip
되어도 화일을 지우게 된다.
RMAN 은 모든 화일에 대한 백업이 Skip 되어도 에러메시지나 경고를 보내지
않는다.
그러나 만일 데이터 화일에 대한 백업이 recovery policy window 보다 오래
된 것 이면 RMAN 은 새로운 백업 화일을 만들기 위해서 화일을 백업 하게 된다.
Note:
자체적인 expirations policy 를 가지고 있는 media manager 를 사용할 경우에는
이런 백업 최적화 정책을 사용하는 것에 신중을 기해야 한다.
백업 최적화 를 사용하기 위해서는 CONFIGURE 명령을 사용한다. CONFIGURE
명령은 명령 수행 이후에 이루어지는 모든 백업에 대해 적용이 된다.
예:
CONFIGURE BACKUP OPTIMIZATION ON; # default 는 OFF
2. Backup Optimization에 Retention Policies 적용 하기
Retention Policy 로 백업 최적화를 조절 할 수 있다. 그러나 retention policy를
사용하지 않기 위해서는 'CONFIGURE RETENTION POLICY TO NONE' 을
이용해서 명시적으로 retention policy를 사용하지 않는다고 해야 한다. 디폴트로
REDUNDANCY = 1 이 적용 된다.
a. Recovery Window 를 이용한 Backup Optimization
만일 백업 최적화가 enable 되어 있고 Recovery Window 가 retention policy
적용을 위해서 셋업 되어 있으면 RMAN 은 항상 가장 최근의 백업이 Recovery
Window 보다 오래된 데이터 화일을 백업한다.
예를 들면 다음과 같은 조건에서
o Today is February 21.
o The recovery window is 7 days.
o The most recent backup of tablespace tbs2 to tape is January 3.
o Tablespace tbs2 is read-only.
2월 21일에 tbs2 테이블 스페이스를 테이프로 백업을 하라는 명령을 내리면,
RMAN 은 이 화일이 1월3일 이후에 변경 사항이 없는데도 불구 하고 백업을 하게
된다. 이로써 RMAN 은 최근 7일 동안에 최소한 한번의 백업이 있어야 된다는
조건을 지키게 된다.
이러한 작동 방식은 media manager 가 오래된 테잎을 제거 해도 되도록 한다.
그렇지 않다면, media manager 는 1월 3일의 백업을 무한정 가지고 있게 된다.
2월 21일에 tbs2 테이블 스페이스의 보다 최근의 백업을 만듦으로 써, RMAN 은
media manager 가 1월 3일에 백업 했던 테입을 지워도 되도록 한다.
b. Redundancy 를 이용한 Backup Optimization
Retention policy 로 Redundancy 를 채택 한 경우에 RMAN 은 Redundancy
에 1을 더한 갯수를 초과하는 오프라인 또는 읽기 전용 화일의 백업을 건너뛴다.
이때 'CONFIGURE RETENTION POLICY TO REDUNDANCY n' 명령어로
Redundancy의 갯수를 정한다.
아래와 같은 백업 최적화 명령을 내린 경우를 예로 든다:
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE RETENTION POLICY TO REDUNDANCY 2;
아카이브 테이블스페이스를 한번도 백업을 받은적이 없고 다음의 작업을 1주일
동안 한다고 하자.
Day Action Result Redundant Backup
Monday Take tablespace archive offline clean.
Tuesday Run BACKUP DATABASE. The archive tablespace is backed up.
Wednesday Run BACKUP DATABASE. The archive tablespace is backed up.
Thursday Run BACKUP DATABASE. The archive tablespace is backed up. Tuesday backup.
Friday Run BACKUP DATABASE. n/a Tuesday backup.
Saturday Run BACKUP DATABASE. n/a Tuesday backup.
Sunday Run DELETE OBSOLETE. The Tuesday backup is deleted.
Monday Run BACKUP DATABASE. The archive tablespace is backed up. Wednesday backup.
화요일, 수요일, 그리고 목요일의 백업은 아카이브 테이블 스페이스를 복사 해서
3개의 백업이 반드시 존재 해야 한다는 조건을 충촉 시킨다. (1+Redundancy)
금요일과 토요일에는 백업 최적화 조건에 의해서 아카이브 테이블 스페이스를
복사하지 않게 된다.
RMAN 은 일요일에는 유효기간이 지난 백업 화일을 지우게 된다. 따라서 화요일에
만든 백업은 삭제 된다. 월요일의 전체 백업은 3개의 백업이 존재 해야 한다는 조건
때문에 아카이브 테이블 스페이스를 또 다시 백업하게 된다. 이런 방식으로 백업
사이클이 진행 된다.
3. RETENTION POLICY NONE vs. DEFAULT
주의 사항:
'CONFIGURE RETENTION POLICY TO NONE' 과 'CONFIGURE RETENTION
POLICY TO DEFAULT' 는 그 의미가 같지 않다. 전자는 RETENTION POLICY
자체가 존재 하지 않는다는 의미 이며 백업은 expire 되지 않으며 'DELETE
OBSOLETE' 명령은 사용 할 수 없게 된다. 후자는 디폴트 RETENTION POLICY
(REDUNDANCY 1) 를 사용하게 된다는 의미 이다.
'DELETE OBSOLETE' 명령은 RETENTION POLICY 기준으로 expire 된 백업을
제거 하라는 명령이다.

Hi,
Backup optimisation = +- do not copy empty space.
So, when you issue your BACKUP statement, it backs up the datafile. dot. nothing more.
In order to achieve what you're testing, look into TFM for BACKUP INCREMENTAL LEVEL x .
