V126.96.36.199 fixes and updates
For the distributed platform, V188.8.131.52 includes the fixes for the following issues:
- When concurrent requests are being processes, SOAP faults occur and requests are incorrectly discarded on some occasions.
For the z/OS platform, V184.108.40.206 includes the following APAR:
- The web services security related server binding and policy files for all SAML token types are overridden by the files for the User Name Token type.
V220.127.116.11 fixes and updates
This version is made available for the z/OS platform only as APAR PM61633. The same issue for the distributed platforms is addressed in V18.104.22.168.
- APAR PM61633: When concurrent requests are being processes, SOAP faults occur and requests are incorrectly discarded on some occasions.
V22.214.171.124 fixes and updates
APAR PM59150 and APAR PM59637 (PTF UK77061 for both) contain the fixes for the following APARs:
- APAR PM50047: Error responses for IMS synchronous callout messages are returned in UTF-8 encoding. The messages are unreadable in the ICAL I/O area. With this fix, the error response messages are now converted to EBCDIC format and in all uppercase letters.
- APAR PM50048: The SOAP Gateway debug log buffer does not take into account the format of the correlation token that is added to synchronous callout request, response, or error messages. The binary format of the correlation token resulted in incorrect offset for the subsequent hexadecimal data in the log. In addition, Cyrillic characters in the data portion are represented by 2 hexadecimal bytes, causing the data to be incorrectly aligned. The issue is corrected.
- APAR PM50051: For the one-thread-per-tpipe callout thread management configuration, after the SOAP Gateway callout threads are stopped and then restarted (or the server is stopped and restarted), the first synchronous callout request on each tpipe to SOAP Gateway is returned to OTMA with a NAK response by IMS Connect. Subsequent synchronous callout requests are processed normally. This fix sends a cancel ICAL call with the client ID to IMS Connect to cancel the callout request on the tpipe. The first synchronous callout request after the callout thread restart is now processed normally.
- APAR PM52036: For the provider scenario, when a web service is undeployed, the associated service WSDL file and all imported XSD files are removed from the wsdl/ directory in the master configuration. If other web service WSDL files references the same XSD files, later redeployment of those web services would result in unresolved resource errors.
The issue is caused by the following behaviors:
- When a web service is initially deployed, a copy of the service WSDL file and any imported XSD files is stored in the master configuration in the wsdl/ directory if these files are located elsewhere during the deployment. This copy is used when the service is redeployed.
- When the web service is undeployed, its service WSDL file and all referenced XSD files in the master configuration are removed.
This behavior prevents multiple web services to share the same XSD file or import XSD files of the same name but different content. This fix resolves the issue for the provider scenario with the following behavior changes:
- When a web service is deployed, the related WSDL and XSD files are bundled into the web service Axis ARchive file (AAR file). SOAP Gateway no longer copies the WSDL and XSD files into the WSDL directory in the master configuration if these files reside somewhere else.
- Upon startup, SOAP Gateway now loads web services directly from the AAR files instead of the wsdl/ directory in the master configuration.
- When a service is undeployed, only its correlator and AAR files are deleted. No files from the master configuration wsdl/ directory are removed.
Restrictions: For the consumer (callout) and business event scenarios, you cannot import the same XSD file or have nested XSD import statements.
- Problem: Lowercase characters in error response messages to callout requests are not correctly rendered with the UTF-8 code page. Non-error responses are processed correctly.
Solution: This issue is addressed as a result of the fix for APAR PM50047.
- Problem: User authentication details from the SOAP message header (when WS-Security is enabled) are not propagated to IMS Connect. The authentication details from the web service connection bundle definition are used instead.
Solution: This issue is addressed in 126.96.36.199.
V188.8.131.52 includes cumulative fixes and updates in the previous maintenance release, V184.108.40.206. See the following section for bug fixes in V220.127.116.11.
V18.104.22.168 fixes and updates
V22.214.171.124 includes the following fixes and updates:
- APAR PM50044 (PTF UK75938): For SAML tokens, the NotOnOrAfter attribute should be optional when the tokens are used to validate SOAP message timestamp. Evaluation of the clockSkew value defined in the bindings.xml file should take into consideration the NotOnOrAfter value. With this fix, the NotOnOrAfter value is optional, and is considered when the clockSkew value is evaluated.
- APAR PM50046 (PTF UK75938): User authentication details from the SOAP message header (when WS-Security is enabled) are not propagated to IMS Connect. The issue is addressed.
- APAR PM50049 (for Windows only; no PTF for the z/OS platform): The SOAP Gateway server running on Windows should remain running when the Windows user logs off. The SOAP Gateway server can now be installed and run as a Windows service. The server remains running when the user logs off.
For the Windows service support, new messages and new SOAP Gateway management utility commands are added to support:
- Installing and uninstalling the SOAP Gateway server as a Windows service
- Starting, stopping, and checking the status of the SOAP Gateway server as a Windows service.
Recommended APARs for Java updates for SOAP Gateway running on z/OS:
APARs PM56817, PM57009, and PM56825 provide an updated version of Java (V126.96.36.199) for IMS Enterprise Suite V2.1 that addresses reported memory leak and data corruption issues on the z/OS platform.
Before you upgrade
Save a copy of the following files:
- Files under the <SOAP_Gateway_installation_dir>/server/webapps/imssoap/xml directory
- Files under the <SOAP_Gateway_installation_dir>/server/webapps/imssoap/wsdl directory
- Your .aar files in the <SOAP_Gateway_installation_dir>/server/webapps/imssoap/WEB-INF/services directory
If you customized any server configuration files such as any logging properties or security login configuration, save a backup copy before you upgrade. Examples include the log4j.properties or wsjaas.conf files under the <SOAP_Gateway_installation_dir>/server/webapps/imssoap/WEB-INF directory.
You can roll back to the base version after you upgrade. However, your web service artifacts and custom files and settings are not preserved. All your web servicie artifacts and custom files must be manually added back.
Important: For the z/OS platform, before you SMP/E APPLY the fixes in APAR PM82031 , if the following files were customized, you must make a backup copy. After you APPLY this service, copy them back to the original directories:
where -SGW_DIR- is the SOAP Gateway installation directory.
After you upgrade:
- After installing the upgrade, you must run the migration command iogmgmt -migrate to ensure all web service artifacts are up to date.
- If you are upgrading from V2.1 or V188.8.131.52 to the latest version:
- If the WSDL file for your existing provider web service contains XSD import statements, you must manually redeploy your web service.
Previously, imported XSD files were not bundled into the web service AAR file; instead, they were copied into the SOAP Gateway server WSDL directory. This copy was used to deploy the web service and was loaded into the runtime configuration when the SOAP Gateway server started up. The fix for APAR PM52036 changes the behavior. Starting V184.108.40.206, the imported XSD files are now bundled into the web service AAR file, and when the SOAP Gateway server starts up, instead of scanning the XSD files in the WSDL directory, it loads web services directly from the AAR files. Because the SOAP Gateway server will not be able to find the imported XSD files in the AAR files for migrated web services at startup time, existing web services must be manually redeployed.
- For the z/OS platform, you must manually remove the IMSSOAPIVP.aar file for the SOAP Gateway IVP before you start the SOAP Gateway server. With this update, a new IMSSOAPIVPService.aar file is added for the SOAP Gateway IVP service. If the old IMSSOAPIVP.aar file is left on the system, when you start the server, you would encounter an error in the job log stating that the IMSSOAPIVPService service is not valid because a service of the same name already exists. An AxisFault is generated because two services cannot have same name. The IMSSOAPIVP.aar file is located in <SOAP_Gateway_installation_dir>/server/webapps/imssoap/WEB-INF/services. You can use the rm UNIX command to remove the file. For example:
rm -f -Pathprefix-/usr/lpp/ims/imses/V2R1/soap_gw/server/webapps/imssoap/WEB-INF/services/IMSSOAPIVP.aar
This step is not needed for the distributed platforms. The IBM Installation Manager will handle the removal of the old AAR file during the upgrade.
- If the WSDL file for your existing provider web service contains XSD import statements, you must manually redeploy your web service.
You might encounter the following problems with IMS Enterprise Suite 220.127.116.11 SOAP Gateway. Use the indicated workaround to resolve the issue until a fix is made available.
- Problem: After upgrading to V18.104.22.168, existing provider web services whose WSDL files contain XSD import statements cannot be loaded when the SOAP Gateway server starts up after upgrading to V22.214.171.124.
Workaournd: You must manually redeploy your web service. For more information, see the migration step 2 in the After you upgrade section above.
- Problem: Connection information might be exposed when a user navigates to the SOAP Gateway XML directory through the HTTP protocol (such as http://SOAP_Gateway_server:port/imssoap/xml/connbundle.xml).
Workaround: Paste the following text in the <SOAP_Gateway_installation_dir>/server/webapps/imssoap/WEB-INF/web.xml file and restart SOAP Gateway:
- Problem: The CSMOKY status message or other IMS Connect status data is seen inside the first message field of a callout request message.
Workaround: Fill all of the allocated user data area in a callout message with data. Do not pad with blanks.
- Problem: Asynchronous callout request response messages are not being received by the IMS application when the LL, ZZ, and trancode are not included in the response message structure.
Workaround: Left-pad the first field in the response message with 8 blank characters, or include the LL, ZZ, and trancode values.
- Problem: Web service timeout values are overridden by the timeout value of the first callout request that times out before the external web service returns a response. This timeout value is then used by all subsequent web service requests until the server is restarted.
Workaround: For all correlators, set the callout web service timeout value to the largest timeout value needed for any IMS callout requests to receive a response from the external web service.
- Problem: With IMS Version 11, synchronous callout response messages are prefixed with 0000. Four characters of user data are lost from the end of the message.
Workaround: Append four blanks to the end of synchronous callout response messages.
- Problem: A few IOGS messages incorrectly list AIX as one of the supported platforms, when AIX is not a supported platform.
Workaround: No workaround. Ignore the AIX listing.
The fix for APAR PM52036 has impacts on the following topics:
- The following web service deployment related topics should be updated to describe the new behavior when a provider web service is deployed, and the support for multiple web services to import the same XSD file, or an XSD file of the same name but different content.
- The following service undeployment related topics should be updated to remove the statement that the WSDL file is removed from the master configuration when a web service is undeployed:
- The support for multiple web services to import the same XSD file, or an XSD file of the same name but different content should be added to the New features topic:
- The behavior changes should be added to the Changed behavior topic: http://publib.boulder.ibm.com/infocenter/imzic/topic/com.ibm.ims.soap21.doc/sgw_changedpropmsg21.htm
