The first field is the SID. The third field is a flag, either Y or N, that signifies whether or not the database is to be started when the server boots. Or you might have upgraded your db. So the entries in oratab might be dicey. It will really help you a lot if you first start the OS administration first before starting the DB part.

This article describes the installation of Oracle Database 12c Release 1 The article is based on a server installation with a minimum of 2G swap, with SELinux set to permissive and the firewall disabled. The following package groups were included for this installation.
An example of this type of Linux installations can be seen here. Alternative installations may require more packages to be loaded, in addition to the ones listed below. The Oracle Home User has complete control over the Oracle base for a particular home. For security reasons, different Windows User Accounts used as Oracle Home Users for different Oracle homes are not allowed to share the same Oracle base.
This means that if you choose to reuse an Oracle base from an earlier release of Oracle Database in Oracle Database 18c, then the Oracle Home User of Oracle Database 18c Oracle home has complete control over the Oracle base of the earlier release.
In a default Windows installation, the Oracle base directory appears as follows, where username is the Oracle Installation user if you choose Windows Built-in Account as the Oracle Home User, or it is the Oracle Home user if one is specified:. For example, if the user grid is the Oracle Home User for the Oracle Grid infrastructure installation and the user oracle is the Oracle Home User for the Oracle Database installation, then you have two Oracle base directories.
