Websphere MQ Back-out queue configuration - ibm-mq
I have DMLC listener that listens to messages from Websphere MQ 7.5.0.2. When there is a poison message, i wish to put it in the back-out Q after the retry count in MQ expires.
I have configured the back-out queue on the MQ, with the threshold value at 3.
However, what actually happens wen i throw an exception on the listener, the message is still being redelivered way more than 3 times and the the message goes back to the same queue every time and the cycle is repeated continuously.
The back-out threshold increases in MQ, but never the message never goes to the back-out Queue.
Am i missing something somewhere?What should i do if i want the message to be put in the back-out Queue.
Referring to the official docs below, there isn't any additional configuration for this.
Websphere Poison Message Handling
Is there any additional configurations that I need to do ?

The key error you have provided from the queue manager's AMQERR01.LOG is below:
AMQ8077: Entity 'user#domainNname' has insufficient authority to access object
'ORANGE.LOCAL.QUEUE'.
EXPLANATION:
The specified entity is not authorized to access the required object. The
following requested permissions are unauthorized: put/passall
Based on the error provided, the user which is attempting to access the back out queue is user#domainNname.
From all of the information provided it appears that user#domainNname is only missing permissions to ORANGE.LOCAL.QUEUE, the following command should add the require permissions:
SET AUTHREC PROFILE(ORANGE.LOCAL.QUEUE) OBJTYPE(QUEUE) PRINCIPAL('user#domainNname') AUTHADD(PUT,PASSALL)
Note that back out queue processing in JMS will first attempt to use the specified BOQNAME for the queue that is being consumed from, if it is unable to open or put to this queue for any reason such as permission error, or queue full, it will then attempt to put to the queue manager's dead letter queue. This is why you also see an error in your logs stating insufficient authority to access object 'DLQ'.

IBM MQ version 7.5 error AMQ7472: Object %CHLBATCH.706, type scratchpad damaged
We are currently having an issue with an MQ Cluster were a CLUSSDR channel is going into retry as the receiving MQ object is showing as damaged. Configuration is many QMGR's (STAT00-11) sending messages to the Cluster of 4 QMGR's, 2 FullRepos (HUB01-02 and 2PartialRepos HUB03-04) Problem is that on the STAT02 QMGR the CLUSSDR channel to HUB01 is in a retry state with the MQ log error; AMQ9506: Message receipt confirmation failed. and on HUB01 the MQ log errors; AMQ7472: Object %CHLBATCH.706, type scratchpad damaged. (many) AMQ9999: Channel 'TO_HUB01' to host 'server02 (n.n.n.n)' ended abnormally. AMQ9588: Program cannot update queue manager object. (single instance) AMQ9587: Program cannot open queue manager object (many) I have now stopped the CLUSSDR on STAT02 to HUB01 and there is no longer any log entries, however as the QMGR's have linear logging the log files are not being released on the HUB01 QMGR this has introduced a new error AMQ7084: Object syncfile, type syncfile damaged. which is filling up the disk. I have so far tried to recover the damaged object, the command used was on the HUB01 QMGR rcrmqobj -m HUB01 -t channel TO_STAT02 and this returned the result, AMQ7085: Object TO_STAT02, type channel not found., although the following results contradict this; DIS CLUSQMGR(STAT*) CHANNEL outputs a list of all the STAT* QMGR's which includes the TO_STAT02 channel and the channel status DIS CHS(TO_STAT*) STATUS shows all the channels in a RUNNING state, including the supposed non-existent TO_STAT02 Anyone had similar issues please, note that this is the second occurrence we have had in the last month to different clusters and last time we had to take the drastic action of rebuilding the QMGR once the disk space was exhausted and the QMGR crashed
rcrmqobj -m HUB01 -t syncfile is the correct way to rebuild a corrupt syncfile and if using linear logging this will also repair any damaged scratchpad objects. Damaged scratchpad objects should only ever occur through operational or filesystem error, for example if files were deleted or partially restored from backup and so having a large number is something that you should try and identify the root cause. rcrmqobj -t channel will be able to recover damage to channel object definitions, but it is the synchronization data and its index (syncfile) that is damaged/missing. TO_STAT02 sounds like it is a cluster sender that MQ clustering maintains from information shared within the cluster - you can check on whether a cluster channel has a local channel definition using DEFTYPE on DISPLAY CLUSQMGR.
How to get channel type using 'display clusqmgr(*)' command?
Is there a way to get the channel type using the display clusqmgr(*) command? Following is the output of the command display clusqmgr(*) all but this does not give the channel type.

Correction to my earlier answer, on further research the parameter that indicates the channel type in DIS CLUSQMGR output is DEFTYPE and is documented on the IBM MQ Knowledge center page "DISPLAY CLUSQMGR". The output of the DIS CLUSQMGR command is showing CLUSQMGR entries that the queue manager you ran it against knows about in any cluster or clusters it has joined. If the queue manager it is ran on has successfully joined one or more clusters, this output will include the local queue manager (CLUSRCVR) as well as the full repositories (CLUSSDRB). In addition if the local queue manager has also learned about any other partial repository queue managers (CLUSSDRA) these will show up as well. If it has not successfully joined the cluster it may have only a CLUSRCVR and CLUSSDR listed, no CLUSSDRA or CLUSSDRB entries will be present. DEFTYPE How the cluster channel was defined: CLUSSDR As a cluster-sender channel from an explicit definition. CLUSSDRA As a cluster-sender channel by auto-definition alone. CLUSSDRB As a cluster-sender channel by auto-definition and an explicit definition. CLUSRCVR As a cluster-receiver channel from an explicit definition. The CLUSRCVR would be for the queue manager you ran this against's own Cluster Receiver channel. The "by explicit definition" indicates it is a CLUSSDR defined on the queue manager you ran this against, you only need to define one CLUSSDR to one of the Full Repositories, the queue manager will learn the path to all full repositories after connecting to that full repository. If it shows up as CLUSSDR in DEFTYPE, the queue manager has not yet successfully established a connection to the cluster full repository. Once it connects to the full repository DEFTYPE will indicate it is both auto-definition and explicit (CLUSSDRB). If it shows auto-definition only (CLUSSDRA) that is a queue manager the queue manager you run this on has learned about from the cluster.
How to publish Threshold event of combined connections to Message Bus?
What's the topic of connection threshold events? How do I listen to connection count threshold events over the message bus, and how do I figure out what is the current connection count?
Connection threshold events can be published over the message bus to the following topics: #LOG/WARNING/VPN/<router-name>/VPN_VPN_CONNECTIONS_HIGH/<vpn-name> when the connection count exceeds the high threshold. #LOG/INFO/VPN/<router-name>/VPN_VPN_CONNECTIONS_HIGH_CLEAR/<vpn-name> when the connection count goes below the clear threshold. If desired, you can apply wildcards to the topics. For example, #LOG/*/VPN/<router-name>/VPN_VPN_CONNECTIONS*/<vpn-name>. Note that you will need to fill in <router-name> and <vpn-name> with appropriate values. In order to have the connection count threshold events published over the message bus, you will need to do the following: a. Configure the VPN to "Publish Message VPN Event Messages". b. Your application needs to subscribe to the topic for connection threshold events. In order to figure out the current connection count, you will need to send a SEMP over message bus query. a. Enable SEMP over Message Bus Show Commands on the VPN. b. Send a SEMP over Message Bus query. There's an SempGetOverMB sample in the API with detailed instructions to do this. You can also refer to the documentation for details. <rpc semp-version="soltr/7_2"> <show> <message-vpn> <vpn-name>default</vpn-name> </message-vpn> </show> </rpc> c. Parse the XML based response. <rpc-reply semp-version="soltr/7_2"> <rpc> <show> <message-vpn> <vpn> <name>default</name> <connections-service-smf>3</connections-service-smf> <connections-service-web>0</connections-service-web> <connections-service-rest-incoming>0</connections-service-rest-incoming> <connections-service-mqtt>0</connections-service-mqtt> <connections-service-rest-outgoing>0</connections-service-rest-outgoing> <max-connections>10</max-connections> <max-connections-service-smf>9000</max-connections-service-smf> <max-connections-service-web>9000</max-connections-service-web> <max-connections-service-rest-incoming>9000</max-connections-service-rest-incoming> <max-connections-service-mqtt>9000</max-connections-service-mqtt> <max-connections-service-rest-outgoing>6000</max-connections-service-rest-outgoing> ... Removed non-relevant portions for clarity ... </vpn> </message-vpn> </show> </rpc> <execute-result code="ok"/> </rpc-reply> Note that there is a system limit of 10 SEMP poll requests per second, and some topics should not be polled. Refer to the documentation for details.
Invalid Engine ID error in SNMP v3 microchip with manage engine MIB browser
I'm getting error for "SNMPv3" of invalid engine ID? what causes this error usually? it perfectly works when i select no auth,no priv. but for other two options of auth,no priv and auth,priv it gives error of invalid engine id.
ManageEngine MibBrowser supports auto-discovery of SnmpEngineID, EngineBoots and EngineTime from an Authoritative SNMP Engine. If user has enabled the "Set EngineID For Adding V3 entry" and entered SNMPV3 user details with EngineID parameter, MibBrowser displays the message received from Agent. As per RFC3414, If the value of the msgAuthoritativeEngineID field in the securityParameters is unknown then: a) a non-authoritative SNMP engine that performs discovery may optionally create a new entry in its Local Configuration Datastore (LCD) and continue processing; or b) the usmStatsUnknownEngineIDs counter is incremented, and an error indication (unknownEngineID) together with the OID and value of the incremented counter are returned to the calling module. Note in the event that a zero-length or other illegally sized msgAuthoritativeEngineID is received,b) should be chosen to facilitate engineID discovery. Otherwise, the choice between a) and b) is an implementation issue. If Authoritative SNMP Engine returns "unKnownEngineID OID"(.1.3.6.1.6.3.15.1.1.4.0) with incremental counter value to manager. Then, Mibbrowser displays the "Invalid EngineID" error. Regards, ManageEngine

Error not in AppFabric. The service need more size to transmit messsage to other endpoint. You remember this configuration must be the same at both endpoints.
