having a bit trouble in shrinking the transaction logs

Hi all,

I am using Sql 2008 r2 database and I want to shrink the Transaction logs by giving the script.

DBCC SHRINKFILE(PEMDMPRD2_m000_Log, 1)

But we are unable to achieve the desired result, kindly guide me how I can achieve my desired result.

NOTE: I want to perform the shrink to at-least 50% but am able to achieve only 2% and I don’t want the database to be disturbed as it comprises of production data. Thanks and regards, Kaushik G
