使用 unixODBC 的 isql 访问 sql 服务器

Question

我正在尝试运行在 sql 服务器（源）上使用客户端服务器上的 isql 进行查询。在客户端服务器上将 rhel6 升级到 rhel7 之前一切正常。我能够连接到 sql 服务器，但没有运行任何查询。我验证了所有驱动程序都在那里，并且 odbc 文件的 none 已更改。我可以在不同的环境中重现它并且工作正常。

$ export ODBCINI=/etc/alternatives/dmexpress/etc/odbc.ini
$ export ODBCSYSINI=/etc/alternatives/dmexpress/etc
$ export LD_LIBRARY_PATH=/etc/alternatives/dmexpress/ThirdParty/DataDirect/lib:/etc/alternatives/dmexpress/lib/:/opt/cloudera/impalaodbc/lib/64:/opt/cloudera/hiveodbc/lib/64
$ export PATH=/etc/alternatives/dmexpress/bin:/opt/cloudera/parcels/CDH/jars:$PATH
$ isql -v Hadoop_Monitoring_Dev $user $password

我确实得到了一个从 odbcinst.ini 调用的跟踪文件，但它告诉我的不多

这是许可问题。我必须让 odbc.ini 可写，这样它才能写 qewsd https://www.ibm.com/support/pages/what-does-qewsd-mean-odbcini-file
