Problem Statement : When we try to access the LLNW TRI² PROD Instance, it was responding very slow. Login page took 2-3 mins, normally it takes 5-10 secs.
Solution : The below steps which we have done to resolve the LLNW TRI² PROD Instance Performance Issue.
1. We need to check if YUM processes are running in the server machine, If yes should kill those processes. This YUM(Yellowdog Updater Modified) is a tool for update/modify the software packages from the RED HAT.
2. We found that the resolv.conf file on these server was still pointing to old DNS Server that was decommissioned so we have updated that.
Reference :
[root@tri2-migrate-prod etc]# cat resolv.conf.old
search phx2.llnw.net
nameserver 10.12.64.15
nameserver 10.12.65.15
[root@tri2-migrate-prod etc]# cat resolv.conf
search phx2.llnw.net
nameserver 10.12.65.30
nameserver 10.12.65.16
nameserver 69.28.136.102
