I am working on my corporate production server and I found that there is no lsnrctl command.
I am trying to fine using oracle account and go to ORACLE_HOME/bin I saw a lot of executable files but no lsnrctl there.
Trying find command and no hope
ps -ef|grep lsnt <=== not found
BUT I can use command line sqlplus to access.
Friend of mind said it must be listener if not, I am not able to access using just sqlplus from command line.
