About This Oracle Service Architecture Leveraging Tuxedo Release

Release 12c R1 (12.1.1)

What’s New and Improved

Oracle Service Architecture Leveraging Tuxedo (SALT) 12c R1 (12.1.1) introduces the following features:

Web Services Configuration Tool

SALT 12c provides an HTTP-based configuration tool to expose existing Oracle Tuxedo services as Web services without manually editing configuration files. It allows you to learn service definitions for existing Oracle Tuxedo services, edit service definitions in metadata repository, and create Web services definitions and SALTDEPLOY files through an easy to use graphical user interface.

For more information, see Enabling the SALT Configuration Tool in the SALT Configuration Guide.

Security Assertion Markup Language (SAML) Single Sign-On (SSO) Support

Provides the ability to recognize an SAML token inside a SOAP message request received by the SALT Web Services Gateway (GWWS). Based on the token contents, GWWS makes the decision to grant or deny access to Oracle Tuxedo resources.

For more information, see Configuring Oracle Tuxedo Web Services/Configuring Security Features in the SALT Configuration Guide.

New Data Type Support

Supports nested View32 data types. It also supports mapping of additional View and View32 primitive types to and from XML.

For more information, see Data Type Mapping and Message Conversion in the Oracle Service Architecture Leveraging Tuxedo Programming Guide.

Note:

Oracle Service Architecture Leveraging Tuxedo Python, Ruby and SCA features are now part of Oracle Tuxedo 12c Release 1 (12.1.1). For more information, see Oracle Tuxedo 12c Release (12.1.1) documentation.

Upgrade Considerations

For information on installing SALT 12c Release 1 (12.1.1) on top of a previous SALT release, see the Oracle Service Architecture Leveraging Tuxedo Installation Guide.

Known Issues

The following sections describe known problems in SALT 12c Release 1 (12.1.1). Entries include a description of the problem, and a workaround or solution where appropriate.

Each problem is listed by the Change Request (CR) or BugDB number.

•	GWWS Runtime

•	Interoperability

GWWS Runtime

 

CR Number	Description and Workaround or Solution	Found In
CR334161	Problem: GWWS rejects non UTF-8 inbound SOAP request messages when SignBody WS-Security Policy is enabled. When GWWS is configured with multiple encoding support, it can accept non UTF-8 encoded SOAP requests; however, the GWWS internally converts all non UTF-8 encoding messages into UTF-8 encoding messages for later operation. If a service requires <soap:Body> signature verification, the GWWS always verify the signature against the converted UTF-8 encoded <soap:Body> instead of the original <soap:Body> content. Thus the signature verification always failed.	2.0
	Platform: All
	Workaround: Web service client programs must initiate SOAP requests using UTF-8 encoding when the WS-Security Policy Assertion SignBody is enabled for the corresponding services.
CR328329	Problem: GWWS may reject valid SOAP requests if the target Tuxedo service consumes XML typed buffer as input and the input buffer is defined with “size” restriction in the Tuxedo Service Metadata definition. GWWS automatically adds an additional ‘\0’ to the end of the converted XML buffer. This additional byte may result the XML buffer length exceed the “size” value, hence reject by later Tuxedo buffer validation routine in the GWWS.	2.0
	Platform: All
	Workaround: Enlarge or remove the “size” restriction for XML typed buffer in the Tuxedo Service Metadata Definition.
CR306710	Problem: Tuxedo service may not receive the exact same non UTF-8 encoding string as the string prepared in the SOAP request message. If multiple encoding capability is turned on for the GWWS, and Web Service client programs written in Java send messages with non UTF-8 encoding, GWWS may not send exact the same string value to the Tuxedo service. This is a general problem if different encoding conversion implementations are used. Java encoding implementation has slight difference from ICU encoding implementation (which is used by Tuxedo and SALT), hence an encoding string prepared by the Java program, after ICU “to UTF-8” and “from UTF-8” conversion, may not revert to the exact original string.	2.0
	Platform: All
	Workaround: None. Customers rarely use those characters. If some characters mapping are confirmed due to ICU bugs, please contact Oracle Tuxedo Customer Support.
9281764	Problem: WCF (.Net) C# clients may not handle SOAP 1.2 faults sent back by the GWWS gateway. When an Tuxedo service is exposed as a Web Service using the SOAP 1.2 style, GWWS may return faults such as service unavailable, problems during invocation, etc. When this happens, a C# client will receive an exception indicating that an invalid SOAP fault was received. This is due to the fact that GWWS does not specify an @xml:lang attribute in the /Fault/Reason/Text element returned.	11gR1
	Platform: All
	Workaround: Code the C# client so that it receives the fault as an XML document which can then be parsed, as follows: ... catch (FaultException ex) { MessageFault mf = ex.CreateMessageFault(); XmlReader xr = mf.GetReaderAtDetailContents(); ... } --

Interoperability

 

CR Number	Description and Workaround or Solution	Found In
CR330363	Problem: SALT multiple encoding feature does not interoperable with Microsoft .NET WCF 3.0 engine. If SALT enables multiple encoding feature, when the inbound call Tuxedo service returns MBSTRING or XML typed buffer with non UTF-8 encoding, the SOAP response message is encoded the same as the MBSTING or XML buffer. Such SOAP response message cannot be accepted by those Web Service client applications developed using Microsoft .NET WCF 3.0 engine.	2.0
	Third-Party Web Service Toolkit: Microsoft .NET WCF 3.0
	Workaround: Customers may need to develop custom encoder/decoder if the Tuxedo service may return non UTF-8 typed buffers and GWWS multiple encoding feature is turned on. Alternatively, you may explicitly turn off the GWWS multiple encoding feature if you are aware all Tuxedo services in your Tuxedo domain never return non UTF-8 buffers.
CR296594	Problem: SOAP fault response message cannot be accepted by Microsoft .NET 3.0 when the HTTP Content-Length exceeds 65536. If the GWWS server returns a SOAP fault message when the HTTP Content-Length exceeds 65536, the .NET WCF 3.0 engine sends an exception to report the response is not well-formed. Note: If the GWWS server returns a normal SOAP message (non SOAP fault) when the HTTP Content-Length exceeds 65536, the .NET Web service engine can accept.	2.0
	Third-Party Web Service Toolkit: Microsoft .NET WCF 3.0
	Workaround: None. Avoid to return big buffer when invoking tpreturn() along with TPFAIL status code in the Tuxedo service.
CR294785	Problem: Apache Axis2/Java fails to handle Tuxedo FML32 TPFAIL response buffers that have field names with initial uppercase. If a Tuxedo service returns TPFAIL with FML32 buffer, SALT maps each field as an XML segment in the SOAP fault detail, and the field name is used directly as the XML element tag name. If the FML32 buffer contains field names with initial letter uppercase, Axis2 may not recognize the SOAP fault messages that converted from this Tuxedo FML32 buffer.	2.0
	Third-Party Web Service Toolkit: Apache Axis2/Java
	Workaround: Modify the FML32 field name to avoid use initial uppercase name. Corresponding Tuxedo application also needs to be changed and re-compiled.
CR306978	Problem: Apache Axis2/Java does not recognize the SOAP with Attachment (SwA) featured WSDL file generated by SALT. If SwA featured WSDL file is generated by SALT, Apache Axis2 wsdl2java utility generates Java stub code which is different from Apache Axis. Axis2 generated stub code cannot initiate a successful call to SALT service.	2.0
	Third-Party Web Service Toolkit: Apache Axis2/Java
	Workaround: Use Apache Axis instead for SwA featured soap calls. MTOM is an alternative attachment format that supported by SALT. You may also use MTOM feature with Apache Axis2/Java for CARRAY buffer stream.
CR296221	Problem: Apache Axis wsdl2java utility fails to compile the SALT generated WSDL file if soap 1.2 binding with soap fault is defined in the WSDL file.	2.0
	Third-Party Web Service Toolkit: Apache Axis
	Workaround: This is an Apache Axis bug, please refer to https://issues.apache.org/jira/browse/AXIS-2614. You may define SOAP version 1.1 for SALT WSDL if Apache Axis has to be used for Web Service client programming. Or you should manually re-compile Apache Axis classes using Apache Axis source code with the fix provide in the above URL link. You may also choose another third-party Web Service client toolkit for soap 1.2 binding with soap fault feature, such as Oracle WebLogic 9.x Web Services, Apache Axis2, Microsoft .NET WCF 3.0, etc.
CR323477	Problem: GWWS fails to call external Web Service applications built upon Microsoft .NET WCF 3.0 if asynchronous WS-Addressing feature is enabled. SALT supports WS-Addressing feature that conforms to WS-Addressing standard 200408 submission. While initiating an asynchronous outbound call, GWWS always defines a <wsa:ReplyTo> endpoint reference in the WS-Addressing soap header. See the following sample <wsa:ReplyTo> segment: <wsa:ReplyTo>   <wsa:Address>     http://myhost:7102/?wsa_Msg_ID=uuid:B437A4F4-AF23-111E-FFFFFFAC1622FFFFFF9F0000-6BBE   </wsa:Address> </wsa:ReplyTo> Host name “myhost” and port number “7102” in the above sample indicates the listening endpoint that is created by the GWWS which is used to accept asynchronous soap response messages for outbound calls. But Microsoft .NET WCF 3.0 does not recognize the <wsa:ReplyTo> endpoint in the request, and always returns the synchronous response through the request connection. GWWS then always encounters time out in receiving asynchronous response because Microsoft .NET WCF 3.0 never send the response to GWWS expected endpoint.	2.0
	Third-Party Web Service Toolkit: Microsoft .NET WCF 3.0
	Workaround: None. You should disable WS-Addressing feature when initiating outbound call to external Web Service applications built upon Microsoft .NET WCF 3.0. For more information about configuring WS-Addressing feature, see “Configuring Advanced Web Service Messaging Features” in the Oracle Service Architecture Leveraging Tuxedo Configuration Guide.
