Description :After an upgrade of the second DUAS instance on a system with multiple instances and multiple Network Interface Cards:
- The EEP of the second instances refuses to come up at startup with following error in the logs.
- Netstat reveals that the EEP port is actually taken by on specific IP by the EEP of the already running instance.
Error Message :
Could not add listen endpoint on 0.0.0.0:XXXXX. Could not bind socket (errno=67)
Root Cause: This is a setting issue. Following variables have to be created in the environment with the correct settings.
U_CLUSTER and UNI_SRV_BIND_NAME
U_CLUSTER set to Y allows the processes to bind the IP or related NIC that ressolves the node name U_LOCALHOSTNAME.
UNI_SRV_BIND_NAME forces EEP must be set to the Hostname set in U_LOCALHOSTNAME.
OS: All OS
Stop the node
Check that all the Dollar Universe process are correctly stopped
Execute the following command from the bin folder
./unisetvar U_CLUSTER Y
Additionally, if the current U_LOCALHOSTNAME points to a wrong hostname or IP, change it with the command units:
./unims -update -host CORRECTIP
That way ALL Dollar Universe processes will ONLY listen into the IP CORRECTIP ( to be replaced by the IP).
Restart Dollar Universe (DUAS should be restarted because both settings are static).
