We have an old messy thirdparty application at work that uses Oracle. Sometimes the application tends to lock the Oracle system and use a LOT of threads, leaving the system pretty much unresponsive. To be able to kill all 1000+ Oracle-plus processes i created a small script that kills all processes.

1 2 3 4 5 6 7 8 9 10 11 12 13 |
USE MYDB; GO -- Truncate the log by changing the database recovery model to SIMPLE. ALTER DATABASE MYDB SET RECOVERY SIMPLE; GO -- Shrink the truncated log file to 1 MB. DBCC SHRINKFILE (MYDB_Log, 1); GO -- Reset the database recovery model. ALTER DATABASE MYDB SET RECOVERY FULL; GO |
