I need to quickly (and forcibly) kill off all external sessions connecting to my oracle database without the supervision of and administrator. I don't want to just lock the database and let the users quit gracefully. How would I script this?

I have searched for the flashback command. Somewhere it is written we can rollback the truncate operation, and somewhere it is written we can't rollback. Can the FLASHBACK command in Oracle used to rollback the truncate table operation? Lalit Kumar B You need to have Flashback Data Archive enabled. Then the truncate could be reversed with a statement like this: insert into <truncated_table> select * from <truncated_table> as of timestamp <some time>; Thanks to @ Jon Heller for adding this useful information about the new feature: This requires version 11.2 or higher, which introduced support

An update SQL query was executed on the server, which caused many problems later. How can I get the list of update queries executed in last 2 months, so that I can trace the exact problematic SQL query? select v.SQL_TEXT, v.PARSING_SCHEMA_NAME, v.FIRST_LOAD_TIME, v.DISK_READS, v.ROWS_PROCESSED, v.ELAPSED_TIME, v.service from v$sql v where to_date(v.FIRST_LOAD_TIME,'YYYY-MM-DD hh24:mi:ss')>ADD_MONTHS(trunc(sysdate,'MM'),-2) where clause is optional. You can sort the results according to FIRST_LOAD_TIME and find the records up to 2 months ago. For recent SQL: select * from v$sql For history:

I have a database in a local file that is used by a program. The program has limited functionality and I needed to run some quick queries. I installed SQL Server Management Studio Express 2005 (SSMSE), connected to the SQL Server instance, attached the database file, and ran the queries.
