The SAP manager refuses to connect the SAP System.

Environment

OS: All
OS Version: All Operating Systems on which the SAP Manager is supported
Related configuration item(s): SAP manager activated

Cause

Configuration issue, the port definition is missing to connect to the SAP TargetServer in the services file of the host.

Resolution

-----------------------------------------------------------------------------------------------------------------------------------------------
Add in the /etc/services (for Unix/Linux) or  in the c:\windows\system32\drivers\etc\services the following line

sapmsSID 36TS/tcp

Example :

SID: value of R3Name
TS: value of the TargetServer

In the uxjcs.ini the following settings

CLE: BELINT/S/SAP_ECC_*
.....
R3Name: IE1
......
TargetServer: 00
.......

Declare in the etc/services file following entry and save the file.

sapmsIE1 3600/tcp

If that still does not fix the issue, double check that the following parameters in uxjcs.ini are correct after consulting with your SAP admins:

GatewayHost:    <hostname>
Group:             PUBLIC
R3Name:            DEV
MessageServerHost: <host name>
