CLI0164 Master ECB function not supported by CLI/TDP interface
This error is specific to CLI2 master ecb function support. The TDP interface module software level doesn't meet minimum requirement to support the master ECB function. This will be detected at Connect time since the Master ECB must be established prior to a Connect attempt. The Connect attempt will fail.
In the MVS environment the relevant module is HSISXMS and is associated with the target TDP. In the VM environment the relevant module is VMSXMI and is a nucleus extension in the application virtual machine.
