Kill Session vs Disconnect Session

Today my friend asked me what is the different between kill session and disconnect session. After researching I found useful information and here I`m going to share briefly.

  • Using Disconnect Session clause to disconnect the current session by destroying the dedicated server process.
  • Using Kill Session clause let you mark a session as terminated, release locks.

Example:
SQL>ALTER SYSTEM DISCONNECT SESSION 'sid,serial#';
SQL>ALTER SYSTEM KILL SESSION 'sid,serial#';
