Failed To Connect To Queue Director - Websphere Mq Mistake Inward Java
"Failed to connect to queue manager" fault comes inward WebSphere MQ if whatever Client e.g. Java programme is non able to connect to MQ server due to whatever reason. The argue is genuinely identified past times argue code inward fault message e.g. code 2397 comes when SSL is enabled betwixt customer too server too Java customer is non able to connect to server due to unknown or expired SSL certificates. If you lot are working inward Java application which is using WebSphere MQ for messaging over SSL too then you lot are saltation to human face upwardly some setup, certificate too keystore vs truststore related error. For starting fourth dimension timers agreement SSL too MQ errors is nightmare, forget virtually solving them. I have got gone through that too subsequently spending hours on Google too Websphere MQ documentations, I managed to solve some of the problems nosotros human face upwardly spell connecting to MQ over SSL from our Java application. In this article, I am listing downward these errors too exceptions too their crusade too solution for everyone's benefit. Next fourth dimension you lot human face upwardly whatever MQ SSL issue, hopefully you lot volition detect the right solution to solve these tricky errors. In this tutorial nosotros volition mainly looked at 3 errors :
I have got generally encountered these spell working with Java application which was connecting to other legacy arrangement using MQ for sending too receiving XML files, simply useful to anyone who is using over MQ over SSL.
Error :
SSL handshake failed. [1=javax.net.ssl.SSLHandshakeException[sun.security.validator.ValidatorException: PKIX path edifice failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to detect valid certification path to requested target
Cause : server was moved to dissimilar SSL signer certificates, personal certificates on keystore was expired.
Solution : If personal certificates are expired too then you lot ask to practise novel valid personal certificates too add together them into keystore. Also add together novel signer certificates into trust shop which is used past times server. This would move required during SSL handshake. Once nosotros updated our our Java application's truststore too keystore this fault was solve. It took me long fourth dimension to empathise too gear upwardly this fault because I wasn't aware of exact difference betwixt keystore too truststore too how precisely they are used during SSL handshake process.

Cause: Code 2397 comes when SSL is enable betwixt MQ customer too server simply SSL handshake is failed due to certificates issues e.g. dissimilar signer certs on customer too server side or expired certificates on customer too server side.
Solution: Once nosotros added novel laid of SSL certificate inward keystore too truststore too also deployed inward MQ server this fault was solved. BTW, ever banking corporation check for MQ Error code, because that's to a greater extent than precise too then fault message too MQ role dissimilar fault code for dissimilar exceptions. For Example if both MQ customer too server has right laid of certificates, too you lot are yet non able to connect other, too then in that place could move an effect with SSL Peer setup. Common name, ("cn" plain inward your SSL certificate) of client's personal SSL certificates are required to move added every bit SSLPEER on server side, too if that's non setup, SSL connector volition non found too MQ volition give you lot next fault :
You tin sack banking corporation check hither MQ code for argue is 2059, which is dissimilar than previous code 2397. So paying a closed attending on MQ argue code, with clutters of Exception Stack trace is substitution to identifying the argue behind failure.
Owner: CN=TEST_CERTS, OU=RES, O=APP, L=London, ST=London, C=UK
SSLPeer entry should move :
SSLPEER(CN=TEST_CERTS, OU=RES, O=APP, L=London, ST=London, C=UK)
If SSLPeer is non setup or mutual cite from client's personal certificate is non matching with SSLPEER too then WMQ volition throw next error, when Java Client volition endeavor to connect to MQ server :
You tin sack also role wild bill of fare spell adding SSL Peer on server side e.g. next wild bill of fare volition allow whatever customer which has TEST_CERTS inward it's mutual name.
SSLPEER(CN=TEST_CERTS*)
That's all virtually SSL related errors from WebSphere MQ, also known every bit WMQ. It takes a lot of fourth dimension to troubleshoot too solve this error, peculiarly if you lot don't empathise how SSL,Certificate too Java plant together. WMQ is also a niche applied scientific discipline thence its expected that many Java programmer is non familiar with how it plant too other setup related materials which is generally handled past times middleware team. Communicating with them could move existent hurting if you lot couldn't explicate the right crusade to them. Its amend to befriend them thence that you lot tin sack operate together spell troubleshooting a MQ SSL related issue.

I have got generally encountered these spell working with Java application which was connecting to other legacy arrangement using MQ for sending too receiving XML files, simply useful to anyone who is using over MQ over SSL.
SSL handshake failed : unable to detect valid certification path to requested target
The starting fourth dimension work nosotros human face upwardly was due to death of SSL certificates which our Java customer is using to connect to MQ series. Here is the exact exception :Error :
SSL handshake failed. [1=javax.net.ssl.SSLHandshakeException[sun.security.validator.ValidatorException: PKIX path edifice failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to detect valid certification path to requested target
Cause : server was moved to dissimilar SSL signer certificates, personal certificates on keystore was expired.
Solution : If personal certificates are expired too then you lot ask to practise novel valid personal certificates too add together them into keystore. Also add together novel signer certificates into trust shop which is used past times server. This would move required during SSL handshake. Once nosotros updated our our Java application's truststore too keystore this fault was solve. It took me long fourth dimension to empathise too gear upwardly this fault because I wasn't aware of exact difference betwixt keystore too truststore too how precisely they are used during SSL handshake process.
JMSWMQ2020: Failed to connect to queue manager
This fault was also related to previous work simply it confuses a lot too nosotros spent fourth dimension to consider if queue is available, it allows connector too other properties because it doesn't say anything virtually actual cause, which is expired SSL certificates. If you lot are completely novel inward SSL too Java too then I would also suggest to read my before tutorial about SSL, Certificate too Java to empathise more.Error

Cause: Code 2397 comes when SSL is enable betwixt MQ customer too server simply SSL handshake is failed due to certificates issues e.g. dissimilar signer certs on customer too server side or expired certificates on customer too server side.
Solution: Once nosotros added novel laid of SSL certificate inward keystore too truststore too also deployed inward MQ server this fault was solved. BTW, ever banking corporation check for MQ Error code, because that's to a greater extent than precise too then fault message too MQ role dissimilar fault code for dissimilar exceptions. For Example if both MQ customer too server has right laid of certificates, too you lot are yet non able to connect other, too then in that place could move an effect with SSL Peer setup. Common name, ("cn" plain inward your SSL certificate) of client's personal SSL certificates are required to move added every bit SSLPEER on server side, too if that's non setup, SSL connector volition non found too MQ volition give you lot next fault :

You tin sack banking corporation check hither MQ code for argue is 2059, which is dissimilar than previous code 2397. So paying a closed attending on MQ argue code, with clutters of Exception Stack trace is substitution to identifying the argue behind failure.
SSL Peer Failure
When you lot enable SSL betwixt customer too Server inward MQ, you lot also ask to add together SSL Peer inward WebSphere MQ Server Side. This SSL Peer is mutual cite (CN) from customer applications personal certificates e.g. for next mutual cite :Owner: CN=TEST_CERTS, OU=RES, O=APP, L=London, ST=London, C=UK
SSLPeer entry should move :
SSLPEER(CN=TEST_CERTS, OU=RES, O=APP, L=London, ST=London, C=UK)
If SSLPeer is non setup or mutual cite from client's personal certificate is non matching with SSLPEER too then WMQ volition throw next error, when Java Client volition endeavor to connect to MQ server :
Caused by: com.ibm.mq.MQException: JMSCMQ0001: WebSphere MQ telephone telephone failed with compcode '2' ('MQCC_FAILED') argue '2059' ('MQRC_Q_MGR_NOT_AVAILABLE'). at com.ibm.msg.client.wmq.common.internal.Reason.createException(Reason.java:223) Caused by: com.ibm.mq.jmqi.JmqiException: CC=2;RC=2059;AMQ9643: Remote SSL peer cite error for channel 'ABC.XYZ' at com.ibm.mq.jmqi.remote.internal.system.RemoteConnection.analyseErrorSegment(RemoteConnection.java:4607) at com.ibm.mq.jmqi.remote.internal.system.RemoteConnection.receiveTSH(RemoteConnection.java:3086) at com.ibm.mq.jmqi.remote.internal.system.RemoteConnection.initSess(RemoteConnection.java:1532) at com.ibm.mq.jmqi.remote.internal.system.RemoteConnection.connect(RemoteConnection.java:1201) at com.ibm.mq.jmqi.remote.internal.system.RemoteConnectionPool.getConnection(RemoteConnectionPool.java:354) at com.ibm.mq.jmqi.remote.internal.RemoteFAP.jmqiConnect(RemoteFAP.java:1662)
You tin sack also role wild bill of fare spell adding SSL Peer on server side e.g. next wild bill of fare volition allow whatever customer which has TEST_CERTS inward it's mutual name.
