Since the introduction of SQL Server 2005, there is a simple lightweight trace that is left running by default on every SQL Server. This provides some very valuable. HSQLDB can be run in a number of different ways. In general these are divided into Server Modes and InProcess Mode also called Standalone Mode. All of them have their advantages and pitfalls. The default trace, introduced in SQL Server 2. It provides comprehensive information about changes in the system. One of the most important routes to high performance in a SQL Server database is the index. Indexes speed up the querying process by providing swift access to rows in. Firstly, lets start by answering some basic questions What is the default trace The default trace is enabled by default in SQL Server and is a minimum weight trace which consists by default of five trace files. SQL Server installation directory. The files are rolled over as time passes. How do we know that the default trace is running We can run the following script in order to find out if the default trace is running 1.

Manifold System has exploded onto the GIS scene with unprecedented quality, performance, and value. Also, all available columns are selected for every sub event. Figure 1 This is how the Default trace looks like. So, how can we benefit from each audited category In the following sections I will explain briefly what each category means, as well as some of the sub events, and will provide essential scripts for auditing the events in the Default Trace. Database Events. Lets start with the first event the Database. As we can see, the sub events are pretty much self explanatory the growth and shrinkage of data and log files, together with the changes in mirroring status. It is important to monitor file growths and shrinkages It would be a vast topic to explain why, but in an nutshell, it is because of possible performance issues. Every time a file is grown or shrunk, SQL Server will halt and wait for the disk system to make the file available again. And halt, in this case, means halt no transactions processed until the action is completed. These are the database events that are monitored Data file auto grow Data file auto shrink Database mirroring status change Log file auto grow Log file auto shrink Here is a script which will list the data file growths and shrinkages 1. Polizei Simulator Full. SELECT TE. name. ASEvent. Name,       T. Database. Name,       t. Database. ID,       t. NTDomain. Name,       t. Application. Name,       t. Login. Name,       t. SPID,       t. Duration,       t. Start. Time,       t. End. Time. FROM   sys. CONVERTVARCHAR1. SELECTTOP1                                                             f. FROM   sys.

Time The output of the script will not tell you why the database grew, but will show you how long it took to grow. Be careful about the value of the Duration column, since it might be in milliseconds or in microseconds, depending on the SQL Server version. Also, I would recommend extending this query to search for databases which took longer than, say, a second to grow this is just a guideline. Here is another query which will return the log growths and log shrinking. SELECT TE. name. ASEvent. Name,       T. Database. Name,       t. Database. ID,       t. NTDomain. Name,       t. Application. Name,       t. Login. Name,       t. SPID,       t. Duration,       t. Start. Time,       t. End. Time. FROM   sys. CONVERTVARCHAR1. SELECTTOP1                                                             f. FROM   sys. NULLf                                                     WHERE  f. DEFAULTT       JOINsys. TEONT. Event. ClassTE. WHERE  te. nameLog File Auto Grow       ORte. Log File Auto ShrinkORDERBYt. Start. Time Also keep in mind that the query will not tell you if your junior DBA has been shrinking the data and log files. In the default trace we can find only the AUTO growth and shrink events and not the ones triggered by the ALTER DATABASE statement. Errors and Warnings. Now lets move on to the next section of the events the Errors and Warnings. As we can see, there is an abundance of information here. The Errorlog sub event occurs when something is written to the SQL Server event log Hash and Sort warnings happen generally when a sort or a hash match operation is spilled to disk and since the disk subsystem is the slowest, then our queries become much slower. Missing column statistics events will occur only when the Auto create statistics option is set to off. In this case SQL Server indicates that it might have chosen a bad execution plan. The missing join predicate occurs when two tables do not have a join predicate and when both tables have more than one row. This can result in a long running queries or unexpected results. These categories of errors and warnings are Errorlog Hash warning Missing Column Statistics Missing Join Predicate Sort Warning Here is a script which will outline the errors 1. SELECT TE. name.
