Fix (APAR): PM14403 Status: Fix Release: 6.1.0.29 Operating System: AIX,HP-UX,i5/OS,Linux,Solaris,Windows Supersedes Fixes: CMVC Defect: PM14403 Byte size of APAR: 134962 Date: 2010-05-24 Abstract: DWCT0002E error message at ODR startup when an application with certain URI patterns is installed. HTTP 500 errors afterwards. Description/symptom of problem: PM14403 resolves the following problem: ERROR DESCRIPTION: DWCT0002E error message at On-Demand Router (ODR) startup when an application with certain URI patterns is installed. : Exception: java.lang.NullPointerException at com.ibm.ws.dwlm.client.URIMatcherImpl$Node.getMatchLen(URIMatche rImpl.java:328) at com.ibm.ws.dwlm.client.URIMatcherImpl.put(URIMatcherImpl.java:98 ) at com.ibm.ws.dwlm.client.RequestMapperImpl.makeMatchers(RequestMap perImpl.java:558) LOCAL FIX: n/a PROBLEM SUMMARY USERS AFFECTED: All users of IBM WebSphere Application Server V6.1 PROBLEM DESCRIPTION: DWCT0002E error message at ODR startup when an application with certain URI patterns is installed. HTTP 500 errors afterwards. RECOMMENDATION: Apply the interim fix associated with this APAR or a fix pack containing this APAR so that the URI patterns are properly handled. DWCT0002E error message at On-Demand Router (ODR) startup when an application with certain URI patterns is installed. URIMatcherImpl throws a NullPointerException when an application is installed with a URI pattern where the wildcard precedes some suffix string. Afterwards, the ODR rejects traffic with HTTP 500 errors. PROBLEM CONCLUSION: Code has been corrected so that the URI patterns are properly handled. The fix for this APAR is currently targeted for inclusion in fix pack 6.1.0.33. Please refer to the recommended updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980 Directions to apply fix: NOTE: Mark with an X the: 1) Release the fix applies to 2) The Editions that apply 3) And then DELETE THIS NOTE Fix applies to Editions: Release 6 __ Application Server (Express or BASE) __ Network Deployment (ND) __ WebSphere Business Integration Server Foundation (WBISF) __ Edge Components __ Developer __ Extended Deployment (XD) Install Fix to: Method: __ Application Server Nodes __ Deployment Manager Nodes __ Both NOTE: The user must: * Have Administrative rights in Windows, or be the Actual Root User in a UNIX environments. * Logged in with the same authority level when unpacking a fix, fix pack or refresh pack. * Be at V6.1.0.13 or newer of the Update Installer. Certain iFixes may require a newer version of the Update Installer and the Update Installer will inform you during the installation process if a newer version is required. This can be checked by reviewing the level of the Update Installer in file /updateinstaller/version.txt. The Update Installer can be downloaded from the following link: http://www.ibm.com/support/docview.wss?rs=180&uid=swg21205991 For detailed instructions to Extract the Update Installer see the following Technote: http://www.ibm.com/support/docview.wss?rs=180&uid=swg21205400 Note that there are two different methods for delivering iFixes, depending on the contents. The fix may be delivered either as a single file with a .pak extension (such as 6.1.0.11-WS-WAS-IFPK12345.pak) or a single file with a .zip extension (such as 6.1.0.11-WS-WAS-IFPK12345.zip) which then contains one or more files with a .pak extension. 1) If your iFix is delivered as a single file with a .pak extension, Copy the .pak file directly to the maintenance directory. If your iFix is delivered as a single file with a .zip extension, unzip the file into the maintenance directory. 2) Shutdown WebSphere Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere instance that maintenance is being applied to. 3) Launch Update Installer and click the Next button on the Welcome page. 4) Enter the directory path of the installation location of the WebSphere product you want to update, and click the Next button. 5) Select the "Install maintenance package" operation and click the Next button. 6) Enter the directory path of your maintenance directory where you have the maintenance packages (.pak files) and click the Next button. 7) The Available Maintenance Package to Install page should list all maintenance packages (.pak files) that it finds in the directory path provided in the previous step. The Update Installer will select the correct maintenance packages based on your system configuration and will not allow an invalid combination to be installed. Please keep the Update Installer recommendations and click the Next button and continue with the installation of the maintenance package. 8) Please note that in the future, if a Feature Pack is installed or uninstalled, a different set of iFixes will be needed. Use the Update Installer again at that time, with the maintenance directory location where these maintenance packages are stored, to determine the required interim fixes for the new WebSphere and Feature Pack(s) combination. 9) The maintenance packages could have one of a set of names, and these names will help determine which maintenance package you need to install. The APAR name (PM14403) should appear as part of the filename. Between the APAR number and the .pak extension there will be 0 to 2 characters added. The table below indicates the usage of each of the maintenance packages with respect to which Feature Packs, if any, are installed. |.pak File Names |No Feature Packs|EJB3 Only|WebServices Only| Both | |6.1.0.x-WS-WAS-IFPK12345 | X | X | X | X | |6.1.0.x-WS-WAS-IFPK12345C | X | | | | |6.1.0.x-WS-WAS-IFPK12345CE | | X | X | X | |6.1.0.x-WS-WAS-IFPK12345W | X | X | | | |6.1.0.x-WS-WAS-IFPK12345WE | | | X | X | |6.1.0.x-WS-WAS-IFPK12345E | X | | X | | |6.1.0.x-WS-WAS-IFPK12345EE | | X | | X | 10) Restart WebSphere Directions to remove fix: NOTE: * The user must have Administrative rights in Windows, or be the Actual Root User in a UNIX environments. * FIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED * DO NOT REMOVE A FIX UNLESS ALL FIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED * YOU MAY REAPPLY ANY REMOVED FIX Example: If your system has fix1, fix2, and fix3 applied in that order and fix2 is to be removed, fix3 must be removed first, fix2 removed, and fix3 re-applied. 1) Shutdown WebSphere Application Server. Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere instance that uninstall is being run against. 2) Start Update Installer 3) Enter the installation location of the WebSphere product you want to remove the fix. 4) Select "Uninstall maintenance package" operation. 5) Select file name of the maintenance package to uninstall (for example, 6.1.0.11-WS-WAS-IFPK12345.pak). 6) Verify the Uninstallation Summary and continue with the uninstall. 7) Restart WebSphere Directions to re-apply fix: 1) Shutdown WebSphere Application Server. 2) Follow the Fix instructions to apply the fix. 3) Restart WebSphere Application Server.
