Trying to establish connection from Tableau Windows 10 64 bit to IBM DB2 on zOS. Per instructions on website I downloaded and installed v10.5fp3_ntx64_rtcl.exe which contains DB2 drivers. (I already have DB2 drivers which I used for connection from other clients like DBeaver and Websphere server)
There have been some users reporting that using the 10.5 version of the IBM z/OS series driver has been experiencing some unexpected behavior. Most have seen success by using the 10.1 version of the IBM z/OS series driver for connecting to Tableau Desktop.
