SAS webserver configuration failure: Http port 7980 does not exist

HI Friends,

 

I am receiving one issue when i am running the SAS migration from 9.4 to 9.4.

It is during configuration phase. The error is occuring during Web server configuration. Please find the attched screen shot for the reference.

It is saying the port 7980 does not exist, but there is no process running on that port.

 

The error message from the logs

 

2016-10-18 20:07:52,861 [main] ERROR com.sas.sdw.SDWExceptionHandler - com.sas.sdw.SDWLocalizedException: The HTTP Port 7980 isn't available. If you want to use this port, shut down the process using it and press retry. If you want to choose a different port, press no and restart the SAS Deployment Wizard.

Have you retried? Is it possible something was using the port at the time of configuration but has now released it? How are you confirming if the port is free ("netstat -an | grep 7980" is what I usually do)? The linked log will have additional details as well.

Can you attach the latest vfabrcersvrc_configure*.log ? The checkForErrors log just shows information about determing if any exception was a warning, or an error requiring intervention. 

 

Can you manually open something on port 7980 to confirm it's not a permissions issue? A netcat listener along the lines of

nc -l 7980 -4

nc -l 7980 -6

Ncat: bind to :::7980: Address already in use. QUITTING.

Re: SAS webserver configuration failure: Http port 7980 does not exist

Hi,

 

Now i am attching the log. Also one of my obesrvation from the log is

In the log you will be able to see 2 different servers one is 538(old one from where packages have been created) and 1674 (Where the instllation is going on) but the deployment wizard is searching for the port avaiablity in 538 which is not correct.

 

Any idea?

Hi,

 

just to double check, you are mentioning going from 9.4 to 9.4. Are you doing a same version migration?

Or, is the plan to install a new instance of SAS 9.4 on the same machine another 9.4 is already running?

 

Thanks

Anja

Is this hostname correct "esesslx0538.ss.sw.se"

 

You'll get an unable to bind message if that reverse looks up to an IP not available on the machine as something that can be bound to.

I just modified the host name in the logs for security reasons, the actual entry is correct entry only.

 

Have you understood my observation mentioned earlier, why it is looking for the port availablity in 538 machine.

You'd have to check your response files and confirm the correct hostnames were entered during the prompting phase. You can examine your response files and see if anything was incorrectly entered (or defaulted to the old hostname accidently somehow) 

 

At this point it's probably best to open a tech support track to track down what happened.
