How To Turn On or Off Recycle Bin for the Instance in Oracle?

You can turn on or off the recycle bin feature for an instance in the instance parameter file with "recyclebin=on/off". You can also turn on or off the recycle bin feature on the running instance with a SQL*Plus command, if you log in as SYSTEM. See the following example:

SQL> connect SYSTEM/fyicenter
Connected.

SQL> SHOW PARAMETERS RECYCLEBIN
NAME                                 TYPE        VALUE
------------------------------------ ----------- -------
recyclebin                           string      on

SQL> ALTER SYSTEM SET RECYCLEBIN = OFF;
System altered.

SQL> SHOW PARAMETERS RECYCLEBIN
NAME                                 TYPE        VALUE
------------------------------------ ----------- -------
recyclebin                           string      OFF

Warning: Turning off the recycle bin feature will give your users hard times on recovering dropped tables.
