WebSphere MQ SENDER channel fails with CSQX202E

ExplanationThe action you requested cannot be performed on channel channel-name. For example, we can only ping a channel from the end sending the message. It is now inactive if it terminated normally when the disconnect interval expired, or stopped if it terminated because of an error or a STOP CHANNEL command. ExplanationThere are too many instances of the channel channel-name running from the connection conn-id to be able to start another. The maximum number allowed is limit and is specified in the MAXINSTC channel attribute. System programmer responseUse the preceding messages on the z/OS console to investigate why Db2 is not available, and restart it if necessary.

ExplanationThere was an error when accessing the channel synchronization data. ExplanationThe channel for which information has been requested is a new instance of the channel. ExplanationThe remote end did not accept the last batch of messages. A value of FFFFFFFF (-1) indicates that no error data was sent by the remote end. System actionThe request fails, and the orphaned channel might remain active. If the channel is already running, for operations other than starting the channel, either stop the channel manually, or wait for it to terminate, and retry the operation.

Where no such message is described, see Distributed queuing message codes for the corresponding message number. The transmission queue name identifies the correct queue, and that queue has the required disposition. ExplanationThe action you requested cannot be performed on channel channel-name because demo forex account it has the wrong disposition. For example, the action asked for a shared channel, but its disposition is private. All definitions of the same cluster topic should be identical; otherwise, problems may arise if our applications rely on one of these attributes to determine messaging behavior.

Current channels include stopped and retrying channels as well as active channels. The maximum allowed is specified in the TCPCHL queue manager attribute, but may be reduced if a dispatcher fails, or if TCP/IP resources are restricted . System actionThe repository manager will check for this condition approximately every hour, continuing for a period of approximately m days from now. If an update for the CLUSRCVR channel is received during this period, these messages will stop.

Phase two is complete once all new information has been received from other members of the cluster. System programmer responseStart the communications system, and try again. If it is of the form 10009nnn or 20009nnn, it is a distributed queuing message code.

ExplanationThere was more than one set of synchronization information in q-name for an instance of channel channel-name. This is probably because the channel is a receiver channel, and there are two sender channels with the same name on different queue managers within the same network address that have communicated with it. If the channel is shared, it might be active on another queue manager.

ExplanationThe repository manager restarted successfully following an error. The channel initiator will try to restart it after the specified interval. ExplanationThe repository manager tried to send a message to SYSTEM.CLUSTER.COMMAND.QUEUE on a queue manager that has the full repository for the specified cluster, but the MQPUT was unsuccessful. ExplanationThe repository manager tried to send a command to another queue manager using channel channel-name.

This causes a CONNECT request to flow from the TCP/IP interface to the remote receiver. TCP/IP waits 3 minutes for a response and if none is received then the start attempt will fail with CSQX202E. It shows the maximum numbers of each type of channel that are allowed. ExplanationThe inbound connection from the address ipaddress would have been blocked because it matches one of the blocked addresses, ip-address-pattern, in the channel authentication table.

If many of the currently operating channels are server-connection channels, consider limiting the number of those using MAXINST or MAXINSTC attributes of a server-connection channel. ExplanationThe channel initiator is shutting down; it owns some active shared sending channels, and they have not been requested to stop. Requests to restart these channels on another queue manager have been issued as shown. System programmer responseCorrect the definitions of the namelist, and start the channel initiator again. SSL communications are requested but no SSL key repository name is specified; that is, the SSLTASKS queue manager attribute is non-zero, but the SSLKEYR queue manager attribute is blank. SSL communications are requested but an error, as reported in the preceding messages, occurred during channel initiator startup processing.

System programmer responseThis might be a temporary situation, and the channel will try again. If it is stopped, issue a START CHANNEL command to restart it. If there are too many channels current, either wait for some of the operating channels to terminate, or stop some channels manually, before restarting the channel. ExplanationThe local security user channel exit for channel channel-name requested data from the remote security user channel exit, but no data was received. System programmer responseCheck that the connection name parameter is specified correctly and that the levels of the queue managers in use are compatible. System programmer responseEnsure that there is a channel defined to process the transmission queue, and that it is not stopped.

System programmer responseFirstly, you need to check that the SSL certificate in the key ring at the local queue manager qmgr-name is valid, for example, in TRUST status and not expired. ExplanationThe operation requested cannot be performed because channel channel-name on the remote end is not of a suitable type. For example, if the local channel is defined as a sender the remote queue manager must define its corresponding channel as either a receiver or requester. ExplanationDuring the processing of channel channel-name, one or more messages have been put the dead-letter queue at the remote queue manager. System programmer responseEnsure the queue name is specified correctly in the channel definition.

System actionProcessing continues, but remote subscriptions are not resynchronized. ExplanationThe Distributed Pub/Sub Offloader task has started successfully. System programmer responseInvestigate the problem reported in any preceding messages. System programmer responseCollect the items listed in the Problem Determination section and contact your IBM support center. System actionChannel initiator termination processing continues. System actionThe recovery process is terminated; some channels might have been recovered, while others have not.

See APPC/MVS return codes for the cause of the return code from APPC/MVS allocate services, and the Writing Servers for APPC/MVS manual for more information. However, this message can also occur in cases where there is no error; for example, if the TCP/IP command TELNET is issued that is directed at the port which the channel initiator is using. A firewall does not allow the connection.When there are multiple links defined on a z/OS image, the image can have multiple host names depending on the link. You need to ensure that the correct host name is used as the sender end.

System actionThe repository manager attempts to continue processing. This message is issued by the channel initiator when the process of switching the transmission queue from old-xmitq to new-xmitq is started. System actionThe listener ends abnormally, and a dump is normally issued. If the listener was not deliberately stopped, the channel initiator will attempt to restart the listener, at the intervals specified by the LSTRTMR queue manager attribute. System programmer responseCorrect the definitions supplied in the namelist so that only authentication information objects with AUTHTYPE of CRLLDAP are named, and restart the channel initiator.

Func is the name of the System SSL function that gave the error, and return-code is the return code . ExplanationThere are too many channels active to be able to start another. The maximum number allowed is specified in the ACTCHL queue manager attribute. ExplanationA trigger message was received to start a channel channel-name to process the transmission queue q-name.

System actionMessages that are not bound to a particular queue manager will be workload balanced. This may take some time if there are a large number of messages assigned to this channel. Check how many using the DISPLAY CHSTATUS(channel-name) XQMSGSA command. ExplanationThe channel channel-name is entering message reallocation because it cannot currently deliver messages to the destination queue manager. ExplanationThe user exit exit-name returned a header compression value that was not one of those which were negotiated as acceptable when the channel started.

PI07181: SHARED SDR RECEIVED CSQX202E RC=00000467 ETIMEDOUT, THE CHANNEL IS WAITING FOR THE TCP

ExplanationThe channel initiator SMF task encountered an error processing channel accounting data. System actionThe process prime xtb ends abnormally, and a dump is normally issued. System actionThe channel initiator will attempt to restart the dispatcher.

Channel channel-name in cluster cluster_name does not satisfy this. Target-id is the identifier of the target queue manager for the channel. System programmer responseCheck the channel and cluster definitions of the sending queue manager. ExplanationIn response to a request to start a channel that was not defined, an attempt was made to define it automatically. The channel auto-definition exit exit-name prevented it being defined. ExplanationAn unexpected communications error occurred for a listener or a channel.

If we do not need to use cipher specifications based on the SSLv3 protocol, you should remove the override that enables the use of SSLv3. System programmer responseObtain a certificate for the certificate authority and add it to the key repository. System programmer responseObtain a new certificate and add it to the key repository.

WebSphere MQ SENDER channel fails with CSQX202E

System actionThe dispatcher ends abnormally, and a dump is normally issued. If the process is a message channel agent, the channel is stopped, and will need to be restarted manually. Return-code is the return code from the z/OS pause service service-name. ExplanationThe repository manager task could not be attached.

System programmer responseSee Communications protocol return codes for the cause of the return code from APPC/MVS allocate services, and the Writing Servers for APPC/MVS manual for more information. Check that the LUNAME queue manager attribute is the same as the PARTNER_LU value for the APPC/MVS symbolic destination used by the listener. System programmer responseCheck that the Db2 tables required by IBM MQ are correctly defined, and restart the queue manager and Db2 if necessary. For further information, and for details of a sample job which shows the information in the Db2 tables, see Problem determination on z/OS. If the local queue manager is correctly a partial repository for the cluster, ensure that the remote queue manager does not have a manually defined cluster sender directed at the local partial repository.

Distributed queuing messages CSQX ..

Use the NETSTAT HOSTs command to display the host names on the image. ExplanationAn unexpected error message code has been issued by the channel initiator. System programmer responseInvestigate why the user exit program set an invalid exit buffer address. The most likely cause is failing to set a value, so that it is 0.

Was this topic helpful?

ExplanationA severe error, as reported in the preceding messages, occurred during channel initiator termination processing. System actionThe CLSTATE attribute of the clustered topic identified by topic-name is set to INVALID and the topic is no longer used by the queue manager. ExplanationAn internal cluster repository command failed to complete successfully. Earlier messages in the log will contain details of the problem. Failure to successfully process a command can leave a cluster in an inconsistent state. ExplanationThis is issued in response to the DISPLAY CHINIT command if the channel initiator is active.

It also shows how many of the active channels are paused, waiting to retry putting a message. It shows how many channels are current, and how many are allowed altogether, as requested by the MAXCHL queue manager attribute. ExplanationAn unexpected SSL communications error occurred for a channel. The channel is channel-name; in some cases its name cannot be determined and so is shown as ‘???? Func is the name of the System SSL function that gave the error, and return-code is the return code (in decimal unless func is ‘gsk_fips_state_set’ in which case it is in hexadecimal). ExplanationThe number of current TCP/IP channels is the maximum allowed; another channel cannot be started.

System programmer responseIf you are using user channel exits, check that your exit is setting its parameter lists correctly. User completion codes are generally the result of errors detected by the Language Environment; see the Language Environment for z/OS Debugging Guide and Runtime Messages soap is a protocol that only works with xml and rest only works with json for information about these codes. This queue manager is unable to start outgoing shared TCP channels, and will not be selected during IBM MQ workload balanced start of a shared channel. This restriction persists until the flag is disabled and the channel initiator is restarted.

ExplanationChannel channel-name cannot start because resources at the remote queue manager are being recovered. System programmer responseEither wait for some of the operating channels to terminate, or stop some channels manually, before restarting the channel, or use the ALTER QMGR command to increase ACTCHL. A change that increases ACTCHL will not be effective until the channel inititator has been stopped and restarted.
