Thank you Mahesh for explanation.
Yes when I am executing nohup ./server.sh & outPut is getting redirected to nohup file.
And when executing only server.sh file after server startup when pressing ctrl+c server is getting down.
Version of IS that I am using is 9.5
Script file i am using to do server startup is InstallationDirectory/IntegrationServer/bin not the one that is residing inside InstallationDirectory/softwareag/profiles/IS/bin.
Now I have started from InstallationDirectory/softwareag/profiles/IS/bin/startup.sh and it is working correctly.
I was facing issue when using the script one residing inside softwareag/IntegrationServer/bin directory
Ideally which script we are supposed to use InstallationDirectory/softwareag/profiles/IS/bin or softwareag/IntegrationServer/bin.So far I remember in 8.x version there was no profile directory softwareag directory.
Scripts are different.
I am trying to understand the logic for this.Will let you know if get something interested.
In the mean time if you get some important,please let me know.
