Error description
After applying IBM MQ fixpack v8.0.0.2 on the Linux (x86-64) platform, error messages of the following form are seen on the console when the MQ Explorer is started: Attribute 265(unknown)missing from type table (2) for object MyQMGR Attribute 262(MQIA_DISPLAY_TYPE)missing from type table (176) for object 176/414d51206170706c65514d20202020200c3ca25606000010 Attribute 262(MQIA_DISPLAY_TYPE)missing from type table (176) for object 176/414d51206170706c65514d2020202020163ca25607100020 Attribute 1644(unknown)missing from type table (25) for object SYSTEM.DEF.AMQP Attribute 1522(MQIACH_PORT)missing from type table (25) for object SYSTEM.DEF.AMQP Attribute 1629(MQIACH_USE_CLIENT_ID)missing from type table (25) for object SYSTEM.DEF.AMQP In addition, some of the panels in the MQ Explorer are blank. The problem happened after connecting to a queue manager which had had its command level updated to the 801 level.
Local fix
Run the MQ Explorer Eclipse initialization routines, using the command as the root user: /opt/mqm/bin/MQExplorer -initialize Alternatively, download the MQ Explorer supportPac MS0T which is not affected by this issue. Note that this supportPac on Linux does not permit a BINDINGs mode connection, so may require the creation of additional channels to connect to the queue manager over TCP/IP.
Problem summary
**************************************************************** USERS AFFECTED: Users of the IBM MQ Explorer v8.0 running on Linux (x86 and x86-64) who are connecting to a queue manager which is using a higher command level than the default for IBM MQ v8.0. Platforms affected: Linux on x86, Linux on x86-64 **************************************************************** PROBLEM DESCRIPTION: When a fix pack is installed on a IBM v8 MQ Linux installation which includes the MQ Explorer package, the Eclipse initialisation routines should be run in order to ensure that Eclipse picks up the latest version of the plugins within its installation directories. However, this initialisation can also delete files which causes the IBM MQ Linux .rpm packages problems when it comes to removal of a fix pack. For that reason, the initialization routine was not invoked during the installation of the fix pack. The consequence of this was that when a fix pack was applied on Linux, the MQ Explorer plugins would not be initialized, and the new code as part of the fix pack would not be used during the running of the MQ Explorer. As of MQ 8.0.0.2, if a queue manager was run with the updated command level, for example by running the command: strmqm -e CMDLEVEL=801 "myQmgrName" then the new code within the plugins is required to comprehend the additional attributes of the queue manager objects. If the updated plugins were not in use (which was the default), then the console would report the missing attributes with messages of the form: Attribute 265(unknown)missing from type table (2) for object MyQMGR each time one of the unknown attributes was encountered, and the MQ Explorer panels may not behave as they are designed to, for example displaying blank panels. A local work around to resolve this problem is to manually run the initialization step. This is achieved using the command: /opt/mqm/bin/MQExplorer -initialize which will cause Eclipse to re-asses what plugins it has available to it, resulting in the newer code being used at runtime. Note that if you use this option, you may find when you come to remove the fix pack that the uninstall of the MQExplorer component will fail, with an error message of the form: WARNING: File /opt/mqm/mqexplorer/eclipse/features/com.ibm.mq.explorer.feature _7.5.0.201504241540/feature_cs.properties is missing. This file belongs to this maintenance pack. Uninstallation will continue. mv: cannot stat `/opt/mqm/mqexplorer/eclipse/features/com.ibm.mq.explorer.featur e_7.5.0.201504241540/feature_cs.properties': No such file or directory ERROR: Unable to move a file back to its install location: "/opt/mqm/maintenance/7.5.0.5/MQSeriesExplorer/opt/mqm/mqexplore r/eclipse/features/com.ibm.mq.explorer.feature_7.5.0.20150424154 0" This maintenance package cannot be uninstalled at this time Aborting uninstallation. error: %preun(MQSeriesExplorer-U200533-7.5.0-5.x86_64) scriptlet failed, exit status 1 This error message can be circumvented by using the rpm uninstall option "--noscripts", for example: rpm -ev --noscripts MQSeriesExplorer-U8002-8.0.0-2.x86_64 If this is done, the installation of MQ MUST be fully removed after completion of the command - and no attempt should be made to use the MQ Explorer until the complete MQ installation has been removed and reinstalled. Once all the MQ components for the installation have been removed, the /opt/mqm directory (if using the default installation location) should be cleared prior to reinstalling, as it will contain remnants of the old installation which were not removed by the uninstallation scripts. Note that the standalone MQ Explorer obtained by the SupportPac MS0T is NOT affected by this problem, because it runs the initialization step as part of its install, and fix packs cannot be applied on this standalone package.
Problem conclusion
The mechanism by which the MQ Explorer is updated by the Linux MQ Explorer fix pack .rpm packages has been updated such that the initialization step is now undertaken by the fix pack install scripts, without preventing the MQ Explorer .rpm component from being uninstalled if files are deleted. Note that this fix applies only to fix packs which contain the code change for this APAR. The behaviour of previous fix pack versions are not altered by this APAR. For example, consider the following install order where the APAR is assumed to be included in the 8.0.0.5 fix pack: Install 8.0.0.0 Install 8.0.0.2 Install 8.0.0.5 Uninstall 8.0.0.5 would leave the MQ Explorer in the same state as before the 8.0.0.5 fix pack was installed - eg. without the new function being enabled. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.5 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
