MQRC_EPH_ERROR 2420 (0974) (RC2420)
- You have specified a channel in MQCONNX and this is not in the CCDT, so if you have a channel called QMACLIENT, and use use “QM” or “QM*” both will give MQRC_HOST_NOT_AVAILABLE.
- You had a network problem, for example the application gets MQRC_CONNECTION_BROKEN. If the next MQ verb the application issues is MQCONN or MQCONNX this will fail with MQRC_HOST_NOT_AVAILABLE. You need to issue MQDISC, or retry the MQCONN(X) a second time.
- You specified a connection address like 127.0.0.1:1414 when it was expecting 127.0.0.1(1414).
MQRC_UNKNOWN_OBJECT_QMGR: 2086 (0826) (RC2086) with a client application
This can be caused when using a client connection and specifying a queue manager name of the format “*name” (for availability) . The application takes this queue manager name, and uses it in the MQOD.
If the first character of the Queue Manager Name is “*” then MQINQ should be used to retrieve the actual queue manager name, or do not use the “*name”.
MQRC_NOT_AUTHORIZED: 2035 (07F3) (RC2035) with MQCONNX
Trying to use MQCONNX to connect to a queue manger. The info from the Knowledge centre and the AMQ message say a blank userid or password was given. I also found the following can cause the same return code
- mqcno.SecurityParmsPtr = 0;
- csp.CSPPasswordLength = 0;
- sp.CSPUserIdLength = 0;
- csp.CSPPasswordPtr= 0;
- csp.CSPUserIdPtr = 0;
- csp.AuthenticationType != MQCSP_AUTH_USER_ID_AND_PWD;
MQRC_ENVIRONMENT_ERROR: 2012 (07DC) (RC2012) with MQCONNX
Trying to use MQCONNX with MQCNO_RECONNECT_Q_MGR or MQCNO_RECONNECT;
- Not using threaded application. My C program was built with -lmqic instead of -lmqic_r -lpthread
- SHRCONV = 0 on the channel definitions
MQRC_Q_MGR_NAME_ERROR: 2058 (080A) (RC2058)
- export MQCHLLIB not pointing to correct location
- export MQCHLTAB pointing to the wrong name, or not set and AMQCLCHL.TAB not found in the location pointed to by MQCHLLIB
- remember to update your .profile so this does not happen again
- you are using a CCDT and passed in a QMNAME of XXXX, for all channels with QMNAME XXXX none could connect to the queue manager in the conname.
- You think you were using a mqclient.ini file … but are now in a different directory
- You are using the correct mqclient.ini file. It has a ChannelDefinitionFile=… file. This ccdt file is missing entries for the queue manager. use the runmqsc command DIS CHL(*) where chltype(eq,svrconn) to display the valid channels on the server.
- You tried to connect with the queue manager name, and need to connect to the QM group name.
- You forgot the * in front of the queue manager name when using groups.
MQRC_KEY_REPOSITORY_ERROR: 2381 (094D) (RC2381)
- MQSSLKEYR not set to the keystore path and file name
- you specified …/key.kdb instead of /key without the .kdb
- remember to update your .profile so this does not happen again
MQRC_OPTIONS_ERROR:2046 (07FE) (RC2046)
During MQCONNX: mqcno.Options = MQCNO_CD_FOR_OUTPUT_ONLY + MQCNO_USE_CD_SELECTION;
Solved it using
- mqcno.Options = MQCNO_CD_FOR_OUTPUT_ONLY + MQCNO_USE_CD_SELECTION
- mqcno.Options = MQCNO_CD_FOR_OUTPUT_ONLY
- but not both
MQRC_CD_ERROR2277 (08E5) (RC2277)
I received message in the /var/mqm/error/*.LOG saying
AMQ9498E: The MQCD structure supplied was not valid.
EXPLANATION: The value of the ‘ChannelName’ field has the value ‘0’. This value is invalid for the operation requested.
This is only partially true. If you specify mqcno.Options=MQCNO_CD_FOR_OUTPUT_ONLY, this returns the name of the channel to you. In this case specifying a blank channel name is valid. If this options value is not specified, then a channel name is required.
AMQ9202E: Remote host not available, retry later.
The attempt to allocate a conversation using TCP/IP to host ” for channel
QMZZZ was not successful. However the error may be a transitory one and it may be possible to successfully allocate a TCP/IP conversation later.
This is not strictly accurate.
In my MQCONNX I specified a channel name of QMZZZ which did not exist in the Client Channel Definition Table (CCDT).
- Check the channel name in ClientConn.ChannelName
- Specify mqcno.Options = MQCNO_CD_FOR_OUTPUT_ONLY so it ignores what is in the channel, and picks one from the entries in the CCDT.
AMQ9498E: The MQCD structure supplied was not valid.
The value of the ‘ChannelName’ field has the value ‘0’. This value is invalid for the operation requested.
Change the parameter and retry the operation.
- I got this when I specified a blank (not ‘0’ ) in the ChannelName field. If I specified mqcno.Options = MQCNO_CD_FOR_OUTPUT_ONLY I did not get this error message, as the specified channelname value is ignored. I fixed the problem by changing the MQCNO, not the MQCD
PCF: MQRCCF_MSG_LENGTH_ERROR: 3016 (0BC8) (RC3016)
I got this when using PCF and got my lengths mixed up, for example StrucLength was longer than the structure.
PCF: MQRCCF_CFST_PARM_ID_ERROR: 3015 (0BC7) (RC3015)
I got this when I issued INQUIRE_Q and passed in a channel namePCF:MQRC_UNEXPECTED_ERROR 2195 (0893) RC2195
I also got back section MQIACF_ERROR_IDENTIFIER (1013) with a value of 2031619. I cant find what this means.
My problem was I had specified an optional section – but not a required one.
PCF:MQRCCF_CFST_PARM_ID_ERROR 3015 (0BC7) RC3015
I got this when using MQCMD_INQUIRE_Q, and I had specified MQCACF_Q_NAMES instead of MQCACF_Q_NAME ( no ‘s’).

So it is in the key store.
You need to check there is profile for the keyring, and as the requester needs access to the private key, has update access to it.
The userid issuing the command may not have access to the keyring. The private key was needed, so needs update access to the keyring.

- The certificate was not in the keyring
- It was NOTRUST
- It had expired
- The CA for the certificate was not in the keyring,
CWWKO0801E: Unable to initialize SSL connection. Unauthorized access was denied or security settings have expired. Exception is javax.net.ssl.SSLHandshakeException: no cipher suites in common
This can be caused by
- the requester not having access to the private key in the keyring.
- no valid certificate in the ring.

The extended error message from the SSL handshake exception is: PKIX path building failed: com.ibm.security.cert.IBMCertPathBuilderException: unable to find valid certification path to requested target.
Action: A client has sent a certificate and Liberty is trying to validate it
- The certificate from the client is self signed and not in the keyring (or trust keyring if this is used)
- The CA or intermeditate CAs are not in the keyring
- The CA’s are in the keyring, but not trusted
- There are CAs with the same name, but not the same content in the keyring. Check dates and other attributes
It may be that the Server’s certificate is being used to validate, so check the certificate being used by z/OSMF or Liberty.
Firefox is getting Error code: SEC_ERROR_UNKNOWN_ISSUER
Check your certificates. You need the CA and any intermediate CAs in the “Authorities” section of certificates. They may need to be trusted.
They are not automatically imported when you import a certificate.
IZUG476E: The HTTP request to the secondary z/OSMF instance “S0W1” failed with error type “HttpConnectionFailed” and response code “0”

I had to restart z/OSMF for it to pick up the change.
Server reports Certificate errors – certificate_unknown
- unable to find valid certification path to requested target
- Rethrowing javax.net.ssl.SSLException: Received fatal alert: certificate_unknown
This was caused by the trust store at the client end did not have the CA certificate for the certificate sent from the server. It may have had it, but it may have expired.
You may also get sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target because the trust store did not have the CA certificate, or the certificate was not valid – for example not trusted, or expired.

The userid issuing the command does not have access to the resource.
The documentation says the shared class cache is created with ONLY USER read/write access by default unless the groupAccess command-line suboption is used, in which case the access is read/write for user and groups.
Note: Users with super user authority gid=0(SYS1) can issue the command with no additional authority.
To find the group list the directories containing the cache, for example if /var/zosmf/data/logs/.classCache/ was specified use ls -ltr /var/zosmf/data/logs/.classCache/javasharedresources.
For me it had owner IZUSVR group IZUADMIN.
I used the RACF command connect COLIN group(IZUADMIN) to connect the userid to the group. Even then the command failed, because groupAccess had not been defined on the -Xshareclasses… parameter. I had to delete the cache so it was recreated next time theJVM started. Then the java -Xshareclasses:cacheDir=/var/zosmf/data/logs/.classCache,name=liberty-IZUSVR,verbose,printStats worked.
