Question

我可以使用所有用户帐户从Eclipse Explorer连接到MQ。但是当我尝试使用我的useraccount（'muthu'）从C客户端连接时，它会抛出错误“MQCONN以原因代码2035结束”。注意：我可以使用相同的C-Client代码访问MQ，同时以root用户身份运行代码（这是mqm组的一部分）。

我目前的设置是

ALTER QMGR PSNPRES(SAFE)
ALTER QMGR PSMODE (ENABLED)
ALTER QMGR CHLAUTH(DISABLED)
SET CHLAUTH(*) TYPE(BLOCKUSER) USERLIST('*NOACCESS')
DEFINE CHANNEL(SYSTEM.ADMIN.SVRCONN) CHLTYPE(SVRCONN) MCAUSER('sampleuser') REPLACE
ALTER AUTHINFO(SYSTEM.DEFAULT.AUTHINFO.IDPWOS) AUTHTYPE(IDPWOS) CHCKCLNT(OPTIONAL)
REFRESH SECURITY TYPE(CONNAUTH)

以下是在AMQERR01.LOG中找到的日志

AMQ9788: Slow DNS lookup for address '172.17.0.1'.

EXPLANATION:
An attempt to resolve address '172.17.0.1' using the 'getnameinfo' function
call took 20 seconds to complete. This might indicate a problem with the DNS
configuration.
ACTION:
Ensure that DNS is correctly configured on the local system. 

If the address was an IP address then the slow operation was a reverse DNS
lookup. Some DNS configurations are not capable of reverse DNS lookups and some
IP addresses have no valid reverse DNS entries. If the problem persists,
consider disabling reverse DNS lookups until the issue with the DNS can be
resolved.

AMQ9209: Connection to host '172.17.0.1' for channel 'SYSTEM.DEF.SVRCONN'
closed.

EXPLANATION:
An error occurred receiving data from '172.17.0.1' over TCP/IP.  The connection
to the remote host has unexpectedly terminated. 

The channel name is 'SYSTEM.DEF.SVRCONN'; in some cases it cannot be determined
and so is shown as '????'.
ACTION:
Tell the systems administrator.

查看您的MQSC代码，我看到您已经定义了一个名为#available的频道，但是我在日志中看到一个名为SYSTEM.ADMIN.SVRCONN的频道正在关闭（连接失败后）。

鉴于您发布的示例程序没有设置MQCNO结构，这是以编程方式传递通道名称的方式，而您没有提到CCDT（这是另一种方式）我怀疑您的SYSTEM.DEF.SVRCONN环境变量是不正确的。
