SAS Web Infrastructure Platform Data Server Configuration Failed : The server cannot be located.

mkiran — Wed, 24 Apr 2024 02:19:38 GMT

I am installing Grid compute node1 and installation failed for WIPD, server process started and I see the PID on linux server but installation not able to find the service. We are on Red Hat Enterprise Linux 8.

re-tried installation after wiping the previous configuration as well but no luck. is there anything missing on OS level?.

An error occurred while starting the Web Infrastructure Platform Data Server on port 9432. The server cannot be located.

[sas@hostname data]$ ps -ef | grep 9432

I might start by checking the data server's log (/sas/platform/config_compute/Lev1/WebInfrastructurePlatformDataServer/Logs) for any errors it's encountering at startup.

@gwootton : Yes, I did verify these logs. All look normal in these logs,. I see database is up and running and log has messages "Database system is ready to accept connection"

Seems like when "pg_isready" is being run it can't connect to the host "hostname.com" on port 9432.

You can repeat these tests outside of the config process. Here I'm using "localhost" instead of "hostname.com":
# Command being run by SAS:
$ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<SASHome>/SASWebInfrastructurePlatformDataServer/9.4/lib
$ export LD_LIBRARY_PATH
$ <SASHome>/SASWebInfrastructurePlatformDataServer/9.4/bin/pg_isready -h localhost -p 9432
localhost:9432 - accepting connections

# Use netcat to test TCP connectivity
$ nc -zv -w1 localhost 9432
Connection to localhost (::1) 9432 port [tcp/*] succeeded!

# Use netstat to confirm postgres process is listening on port 9432
$ netstat -nlp | grep 9432

Thank you @gwootton : I think here is the catch.. when I tried to use "nc" using localhost it is connecting to the DB but not with the actual hostname, is this could be a problem?.

[sas@hostname.com Logs]$ nc -zv -w1 localhost 9432
Ncat: Version 7.92 ( https://nmap.org/ncat )
Ncat: Connected to 127.0.0.1:9432.
Ncat: 0 bytes sent, 0 bytes received in 0.01 seconds.

[sas@hostname.com Logs]$ nc -zv -w1 hostname.com 9432 /*changed the actual servername to a string hostname.com */
Ncat: Version 7.92 ( https://nmap.org/ncat )
Ncat: TIMEOUT.

Found an issue with the DNS , worked with server admin team to correct it.

Thanks @gwootton
