RE: sql*plus autocommit and exit

That's not what autocommit does. You can set autocommit n to some value and it will commit after each 200 transactions. If you don't enter a value it will commit after each transaction. Doesn't have anything to do with commit before logout. It looks like what is happening is an implicit commit because you logged off.  

See item 3 below:
Oracle9i Database Concepts
Release 2 (9.2)

A transaction ends when any of the following occurs:

• You issue a COMMIT or ROLLBACK (without a SAVEPOINT clause) statement.
• You execute a DDL statement (such as CREATE, DROP, RENAME, ALTER). If the current transaction contains any DML statements, Oracle first commits the transaction, and then executes and commits the DDL statement as a new, single statement transaction.
• A user disconnects from Oracle. (The current transaction is committed.)
• A user process terminates abnormally. (The current transaction is rolled back.)

Subject: sql*plus autocommit and exit

Hi:

I have a autocommit value set to OFF however when I exit from SQL*Plus it commits the transaction. Is it a expected behavior?

SQL> show auto
autocommit OFF

SQL> delete from t1;
48601 rows deleted.

SQL> exit
