Problem(Abstract)
Problem working multiple Remote TEMS on same LPAR and one of the Remote TEMS is not starting at all
Symptom
The second Remote TEMS is unable to bind to the well known defined port
(50F6CA85.0115-5:kde12cl.c,110,"KDE1_ServerCall") <0xF4A1019E,0x1A> binding control block: F4A10098 portNo 49624
(50F6CA85.0117-4:kdcsuse.c,120,"KDCS_UseFamily") status=1c010005, "cant bind socket", ncs/KDC1_STC_CANT_BIND_SOCK

Cause
IPV6 protocol is garbing the well known port so IPV4 protocol is unable to bind to the well known port. The netstat -an will display the port information
Resolving the problem
To resolve the problem, disable the IPV6 protocol by using the below variable on both the Remote TEMS and recycle them.
edit $candlehome/config/<hostname>_ms_<tems node name>.config and add
KDEB_INTERFACELIST_IPV6='-'
Points to Remember :
1. In Windows, you can't have multiple Remote TEMS running on the same server. Basically multiple Remote TEMS on the same windows server is NOT supported
2. In Linux/UNIX
You can have multiple Remote TEMS but
a. Each Remote TEMS should use different IP address (nic address)
b. Must be installed in different candlehome directory
c. KDEB_INTERFACELIST must be defined to use interface specific bind
ex : KDEB_INTERFACELIST=!ip address
d. Also, you can have multiple HUB and combination of HUB and Remote TEMS but as along as they satisfies the above criteria
e. You may have to disable discovery of IPV6 interfaces on all the TEMS running on the same server using the below variable
KDEB_INTERFACELIST_IPV6='-'
