Thanks for your inputs Michael. My DBA has just confirmed that our databases are configured with "truncate log on chkpt" and "abort tran on log full". In this case, I can safely use "dump transaction with truncate only". The Transaction Log file shrink operation can be performed only if there is free space on the Transaction Log file, that can be available most of the time after truncating the inactive part of the Transaction Log.
A shrink operation will be useful after performing an operation that creates a large number of Transaction Logs. In this page, you have three options:. Moves all data from the specified file to other files in the same filegroup, in order to delete the empty file later. Shrinking the Transaction Log file to a size smaller than the size of the Virtual Log File is not possible, even if this space is not used. In this case, the SQL Server Database Engine will free as much space as possible, and then issues an informational message, as shown below:.
In the next article of this series, we will discuss the best practices that should be applied to the transaction log in order to get the optimal performance from it. Stay tuned! Author Recent Posts. Ahmad Yaseen. Also, he is contributing with his SQL tips in many blogs. Mission-critical user databases should have log segments on a separate device from data segments. You must use dump tran[saction] Because it copies no data, it requires only the name of the database.
Every use of dump transaction If you have created your databases with log segments on a separate device from data segments, written a last-chance threshold procedure that dumps your transaction log often enough, and allocated enough space to your log and database, you should not have to use this option.
Transaction log dumps are dynamic —they can take place while the database is active. They may slow the system slightly, so run dumps when the database is not being heavily updated. Use dump database immediately after creating a database to make a copy of the entire database. You cannot run dump transaction on a new database until you have run dump database.
Typically, transaction log dumps are made more frequently than database dumps. Use thresholds to automate backup procedures. When space on the log segment falls below the last-chance threshold, Adaptive Server executes the last-chance threshold procedure. Including a dump transaction command in your last-chance threshold procedure helps protect you from running out of log space.
For more information about thresholds, see the System Administration Guide. You can specify the dump device as a literal, a local variable, or a parameter to a stored procedure.
Dumping to multiple stripes is supported for tape and disk devices. Placing multiple dumps on a device is supported only for tape devices. When dumping across the network, specify the absolute path name of the dump device.
The path name must be valid on the machine on which the Backup Server is running. Ownership and permissions problems on the dump device may interfere with use of dump commands. You can run more than one dump or load at the same time, as long as they use different dump devices. If you issue a dump transaction command without the init qualifier and Backup Server cannot determine the device type, the dump transaction command fails.
You must have a Backup Server running on the same machine as your Adaptive Server. The Backup Server must be listed in the master.. This entry is created during installation or upgrade and should not be deleted. If your backup devices are located on another machine so that you dump across a network, you must also have a Backup Server installed on the remote machine.
Dump file names identify which database was dumped and when the dump was made. If you do not specify a file name, Backup Server creates a default file name by concatenating the following:.
For example, the file cationsE contains a copy of the publications database made on the 59th day of
