Switching from Bulk-Logged to Simple Recovery Model on SQL Server 2000

John0990 — Wed, 24 Feb 2010 16:52:55 +0000

Hello, I’ve got a SQL Server 2000 SP4 database that I am considering switching from Bulk-Logged to Simple recovery model. The reason is, there are no transaction log backups happening so the log is just growing to an unmanageable size (40+ GB). I also want to minimize/shrink the log file. What is the easiest (but safe) method to do this? Can I use Enterprise Manager to detach the database and delete the log file, then reattach and switch to Simple model? (Will a new log file automatically be created?) Thanks in advance.

If I change the recovery model on the primary database from full to simple and then change the primary database back to full again. Would that break the log chain? It seems the log shipping breaks after we do that.

Transaction log for read only database…

Dallasfb — Sat, 11 Apr 2009 02:53:44 +0000

Hello there,
I am currently studying for the 70-432 (MCTS SQL Server 2008 I&M) exam and I am using Microsoft 70-432 Training Kit by Mike Hotek. At some point the book claims “when a database is placed in READ_ONLY mode, SQL SERVER removes any transaction log that is specified for the database. Changing the database from READ_ONLY to READ_WRITE causes SQLServer to re-create the transaction log file”.
Well, I have marked a database as read only and changed it back to read write but the transaction file never disappears? Am I doing something wrong, am I not understanding what the book is trying to say or the book is wrong?
Thank you…

Trouble backing up our SQL Server transaction logs

SQL Server Ask the Experts — Fri, 06 Feb 2009 19:13:51 +0000

Our SQL Server transaction logs have not been backing up, and I discovered it’s because a database was not selected in the maintenance plan. When I select the database and save it, however, it is not saving. It keeps reverting back to the previous option. Does anyone know why?

Quick Ques.

Are transaction logs cummulative?

If I have a database set to Full recovery mode; database being backed once a day and transaction logs being backed up hourly, if the database needs to be restored, can I just restore the last transaction log file? Will the last transaction log file contain ALL of the transactions since the last database backup?
