How To Install Microsoft SQL Server on Ubuntu Linux in 5 Minutes - DotNet Blog

They’ve been pushing the open source initiative hard, but I didn’t expect something this big. Oh yeah, Visual Studio is now available for Mac as well. I just saw a pig flying by. While MS-SQL is not open source they have made it available to run on open source platforms such as Linux and OSX, which I can imagine took a ton of work. So I decided to take advantage of this new option and try it out. The first thing I always do on an Ubuntu machine is update it Next we need to import the public repository GPG keys.

For more information about the optional command-line parameters, see the "PSSDIAG Command Line Parameters" section. However, generally it is not necessary to use the optional parameters. After you have extracted the PSSDIAG files from the package on the Microsoft Download Center, run Pssdiag.exe to start the data collection. When PSSDIAG starts, it first opens, and then configures the log files it has been configured to capture. This process may take several seconds. 2003/10/02 12:30:14.90 PSSDIAG Collection started.

Tools Tips and Tricks #9: PSSDIAG Configuration Manager. I had been waiting for Diag Manager to be made public so that this post could go online.

Tools Tips and Tricks #9: PSSDIAG Configuration Manager

Diag Manager is a configuration tool that is used by CSS Engineers to configure a consolidated data collection for Windows Perfmon counters and SQL Server profiler trace (server-side). Additionally, the tool lets you add pre-configured custom diagnostics for Analysis Services configuration data, Mirroring configuration, Event log collection etc. and even custom data collection (using .sql scripts/custom utilities) which can be added using the Custom Diagnostics-> _MyCollectors option. (UI Screenshot below) The tip that I want to talk about with this tool is that .CAB file generated uses a PSSDIAG.XML configuration file when using SQLDIAG to collect data.

If you need to collect data from multiple different instances using the same configuration file, then you can just use the same extracted .CAB file contents with small tweaks to the SQLDIAG.XML file.

Functionality. SQL Server: Optimizing SQL Server Query Performance. How-to install, configure and use Full Text Search - OutSystems.

“Full-Text Search in SQL Server lets users and applications run full-text queries against character-based data in SQL Server tables. Before you can run full-text queries on a table, the database administrator must create a full-text index on the table. The full-text index includes one or more character-based columns in the table. These columns can have any of the following data types:char, varchar, nchar, nvarchar, text, ntext, image, xml, or varbinary(max) and FILESTREAM.Full-text queries can include simple words and phrases or multiple forms of a word or phrase. A full-text query returns any documents that contain at least one match (also known as a hit). A match occurs when a target document contains all the terms specified in the full-text query, and meets any other search conditions, such as the distance between the matching terms.”Full-Text Query Architecture.

Determinar las consultas que mantienen bloqueos. A menudo, los administradores de bases de datos necesitan identificar el origen de bloqueos que reducen el rendimiento de la base de datos. Por ejemplo: está sospechando que el bajo rendimiento del servidor puede ser debido a los bloqueos. Al consultar sys.dm_exec_requests, encuentra varias sesiones en un modo suspendido y con un tipo de espera que indica que un bloqueo es el recurso por el que se está esperando. Al realizar la consulta sys.dm_tran_locks los resultados muestran que existen muchos bloqueos pendientes, pero las sesiones a las que se permitió usar los bloqueos no tienen ninguna solicitud activa que aparezca en sys.dm_exec_requests.

Are you using SQL’s Missing Index DMVs? – Bart Duncan's SQL Weblog. Did you know that your SQL Server is keeping track of the indexes that it thinks you should create? The “missing index” DMVs in SQL are a really great new feature in SQL Server 2005 that (in my opinion) seem to have been underutilized so far. If you want to see if this feature can spare you the tedium of an afternoon identifying poor performing queries and tuning them, all you have to do is ask: You’ll want to run this after your server has been up and running a normal workload for a while.

If this returns no results, that’s good news and indicates that you’re not missing any indexes that are obvious enough for the DMV to detect. If it does return some suggestions, even better: you just improved your server’s perf with almost no work. While to me this feature is so cool it almost seems magical, it does have a few limitations you should be aware of: It’s not as smart as the Database Engine Tuning Advisor. If you’re a typical SQL user, you may not be using these DMVs yet. Traductor de Google. Database-Level Roles. Sql server - Max number of user connections. The maximum number of connections across SQL Server versions and editions is 32,767. You can determine how many connections SQL Server currently has by looking at: SELECT ConnectionStatus = CASE WHEN dec.most_recent_sql_handle = 0x0 THEN 'Unused' ELSE 'Used' END , CASE WHEN des.status = 'Sleeping' THEN 'sleeping' ELSE 'Not Sleeping' END , ConnectionCount = COUNT(1)FROM sys.dm_exec_connections dec INNER JOIN sys.dm_exec_sessions des ON dec.session_id = des.session_id GROUP BY CASE WHEN des.status = 'Sleeping' THEN 'sleeping' ELSE 'Not Sleeping' END , CASE WHEN dec.most_recent_sql_handle = 0x0 THEN 'Unused' ELSE 'Used' END; If the ratio between used and unused connections from the above query is concerning, it is likely that connection pooling is enabled by client applications connected to the server, and those connections are not being efficiently used.

Niveles de gravedad de error del motor de base de datos. SQL Server Profiler: Cómo capturar consultas SQL y el detalle de su plan de ejecución. Casi siempre nos enteramos de que alguna query va lenta por alguna queja de usuario. Ahora se queja que hace tiempo aquella cosa que hacía tardaba tanto y hoy cuando lo ha hecho un par de veces la cosa ha sido más lenta de normal. Realmente puede estar pasando de todo, pero entre las causas comunes podemos encontrarnos de todo un poco: fragmentación en la misma tabla, estadísticas que no están al dia, carga fuera de lo habitual en el servidor en ese mismo momento, incremento del volumen en las tablas implicadas, cambios en la aplicación... Focalizándonos solo en problemas relacionados exclusivamente con la base de datos y si el origen de la queja nos lleva a un informe, nuestro trabajo será mas fácil. Siempre partimos de una query concreta que seguramente podemos extraer rápidamente y lanzarla nosotros desde Management Studio para reproducir el caso.

En cambio, si el problema de lentitud lo tenemos en una operativa de una aplicación como puede ser el ERP empresarial. SQL Server Wait Statistics: Tell me where it hurts - Paul Randal. Niveles de gravedad de error del motor de base de datos.
