SAS services not starting

[woo]

Hello All, 

We have SAS 9.4 M7 installed on Linux 8.4. This is all-in-one machine. Installation and configuration completed successfully. however, when i try starting sas services its showing below message. 

./sas.servers start

starting sas servers 

starting sas web infrastructure data server 

SAS Metadata Server 1 is NOT up

the remaining SAS servers will not be started as a result

However, when i do status it shows both SAS WIP data server and metadata server are up. one thing i am not sure is why its starting sas WIP data server prior to metadata server 

Also, if i starts all services (metadata, wip data server, obj. spawner, dip runner, JMS broker. cache locator, web server, web app server, evm....) individually, everything starts fine...

Running sas.services start calls sas.services.pre first, which starts the WIP Data Server. This is normal behavior.

When it reaches the point to start the Metadata Server it first checks for a PID file (server.hostname.pid) and if found checks to see if that process exists. If not, it runs the start command (i.e. MetadataServer.sh start) and checks for the PID file again. If it confirms the process exists it will go on to check that the log file has indicated the Metadata Server has started successfully. In this case it seems that process is not successful. Does the <SASConfig>/Lev1/SASMeta/MetadataServer/server.hostname.pid file exist, and is it owned by the SAS installation account user?

yes, "server.ip-172-31-8-49.pid" does exist with permission "-rw-rw-r--." and own by "sas" id

I agree with @Anand_V bash debugging might be helpful here to see what's happening. There are also several echo commands commented out that could be uncommented to provide more detail. Be sure to take a backup copy of the file before making any changes. For example:

cp sas.servers sas.servers.bak
sed -i 's/^#echo/echo/g' sas.servers

I think you should check the metadata server log.

May be you can try running in in debug mode? Enable set -x or run using bash -x sas.services start which will print out all the executed commands on the terminal giving more data on what's happening in background.
