IAYMF0026I Check that the name of the TCP/IP address space is correct.

Explanation

The IBM® AD Connect for Mainframe task cannot start because the specified TCP/IP address space is not found.

System action

IBM AD Connect for Mainframe terminates with error.

User response

Verify that the TCP/IP address space is up and running, and that the address space name is specified in the IBM AD Connect for Mainframe parameters correctly. To get the TCP/IP address space name, use the NETSTAT HOME command. Example:
TSO NETSTAT HOME

MVS TCP/IP NETSTAT CS V1R13       TCPIP Name: TCPIP           19:36:27 
User Id  Conn     State
After the address name is verified, it can be set in the IBM AD Connect for Mainframe started task procedure JCL, in the TCPIP keyword parameter. It is common that the name of the address space is also TCPIP, as it is in the following example:
//IAYLSTNR PROC TCPIP=TCPIP,PORT=46000,MAXTASK=20,PROGRAM=IAYCONN,
//          HOSTCP=00037,CLNTCP=00850
