Microsoft Lync Server 2013 : SQL Server Dependencies - Creating SQL Server Maintenance Plans
Maintaining the Lync Server Back End databases is important to the overall health and performance of a Lync deployment. Yet this is an aspect that frequently gets overlooked, primarily because Lync administrators are kept busy caring for other aspects of the Lync environment.
Microsoft Lync Server 2013 : SQL Server Dependencies - Maintaining the Lync SQL Databases
An important aspect of the health of any Lync deployment is maintaining the Lync SQL databases. To keep Lync Server operating smoothly and with optimal performance, regular maintenance should be performed on each SQL Server database.
Microsoft Lync Server 2013 : SQL Server Dependencies - SQL Backup Procedures - Backing Up SQL Using SQL Server Management Studio
Another way to back up SQL is by using the native backup function of SQL to create a flat file backup, which can then become the target for a separate backup application if necessary.
Microsoft Lync Server 2013 : SQL Server Dependencies - SQL Backup Procedures - Backing Up SQL Using Windows Server Native Backup
Windows Server 2008 R2 and Windows Server 2012 contain a native backup application called Windows Server Backup.
Microsoft Lync Server 2013 : SQL Server Dependencies - Lync Database Requirements, Installing SQL Server for Lync
For an Enterprise Edition pool, SQL Server 2008 R2 and SQL Server 2012 are the supported Back End database platforms. Since it is the most recent database release, this section provides step-by-step procedures for installing SQL 2012 in preparation for hosting the Lync Server 2013 Back End databases.
Microsoft Access 2010 : Linking to Another Type of Database (part 2) - Linking to SQL Server Databases
In a system where you store your data solely in Access tables, the Access Database Engine supplies all data retrieval and management functions and handles security, data validation, and enforcement of referential integrity.
SQL Server 2012 : Other PerfMon Log Analysis Tools - Using SQL Server to Analyze PerfMon Logs
Analyzing large quantities of performance logs with SQL Server can be a useful solution when data analysis through other methods could be cumbersome and labor intensive.
SQL Server 2012 : Performance Analysis of Logs - Getting Started with PAL
The Performance Analysis of Logs (PAL) tool is a free utility for analyzing PerfMon counter logs and creating reports highlighting important areas by severity. The report color-codes counters to display problem areas based on thresholds defined by subject matter experts in the support teams at Microsoft.
SQL Server 2012 : Getting More from Performance Monitor (part 2) - Disk or Storage-Related Problems, SQL Server Performance Problems
Sometimes server hardware resources do not cause bottlenecks, but application performance is still bad. In this situation, it’s possible that internal SQL Server resources can become exhausted or depleted
SQL Server 2012 : Getting More from Performance Monitor (part 1) - Investigating CPU Problems, Investigating Memory-Related Problems
The availability of CPU cycles to service SQL Server in a timely manner is critical to database server performance. Configuration-based CPU bottlenecks may include max degree of parallelism, the cost threshold of parallelism, and mis-configured CPU hyperthreading.
SQL Server 2012 : Performance Monitor Overview (part 5) - Remotely Running PerfMon
Like many server management tools, an instance of PerfMon can be connected to a remote server for remote monitoring. This avoids the need to connect via Remote Desktop and may reduce the overhead of monitoring on the target server.
SQL Server 2012 : Performance Monitor Overview (part 4) - Working with Data Collector Sets
User-defined Data Collector Sets in Windows Server 2008 replace the Performance Logs and Alerts from Windows 2000/2003 but the principle is the same
SQL Server 2012 : Performance Monitor Overview (part 3) - Getting Started with PerfMon - Monitoring Real-Time Server Activity, Starting Out with Data Collector Sets
PerfMon is a component of Reliability and Performance Monitor which can be launched from Start ⇒ All Programs ⇒ Administrative Tools. Alternatively, just type perfmon into the Run box and press Enter.
SQL Server 2012 : Performance Monitor Overview (part 2) - New PerfMon Counters for SQL Server 2012
As shown in Table 1, a number of new PerfMon counters are available in SQL Server 2012. Some of these provide logging for new features such as AlwaysOn and FileTable, and some are more detailed counters related to memory utilization.
SQL Server 2012 : Performance Monitor Overview (part 1) - Reliability and Performance Monitor
PerfMon in Windows Server 2008 brings a new look and a new name for the parent snap-in, Reliability and Performance Monitor, although real-time performance monitoring retains the PerfMon name.
SQL Server 2012 : Knowing Tempdb - Configuration Best Practices (part 2) - Tempdb Initial Sizing and Autogrowth , Configuring Multiple Tempdb Data Files
A default installation of any SQL Server edition will create a tempdb database with an 8MB data file and a 1MB transaction log file. For a lot of SQL Server installations these file sizes won’t be enough, but they are configured to autogrow by 10% as needed.
SQL Server 2012 : Knowing Tempdb - Configuration Best Practices (part 1) - Tempdb File Placement
It’s quite a well-known best practice to separate data, transaction logs, and tempdb, and if you knew that already, are you sure you know why? The origin of this recommendation lies with the separation of types of workload between different physical storage, i.e. separate physical disks.
Microsoft SQL Server 2012 : Backup and Recovery Planning - System Databases Recovery, Performing a Complete Recovery
The master database contains key database and security information, and the msdb database holds the schedules and jobs for SQL Server, as well as the backup history. A complete recovery plan must include the system databases.
Microsoft SQL Server 2012 : Recovery Operations (part 4) - Restoring with T-SQL Code
A database backup is a regularly scheduled occurrence, so if SQL Server's built-in Maintenance Plan Wizard isn't to your liking, it makes sense to write some repeatable code to perform backups and set up your own SQL Server Agent jobs.
Microsoft SQL Server 2012 : Recovery Operations (part 3) - Restoring Individual Pages
The ability to restore pages has been available since SQL Server 2005; however, up until now, you needed to use T-SQL code. In this release you can perform this type of restore through a native interface inside Management Studio.
Microsoft SQL Server 2012 : Recovery Operations (part 2) - Performing the Restore with Management Studio
The Restore Database form, as shown in Figure 1, does a great job of intelligently navigating the potential chaos of the backup sequences, and it always offers only legal restore options.
Microsoft SQL Server 2012 : Recovery Operations (part 1) - Detecting the Problem , Recovery Sequences
If a database file is missing, clicking the database in Management Studio pops up a message saying that the database is unavailable. To further investigate a problem, check the SQL Server Errorlog.
SQL Server 2012 : Backup and Recovery Planning - Working with the Transaction Log
Sometimes it seems that the transaction log has a life of its own. The space within the file seems to grow and shrink without rhyme or reason. If you've felt this way, you're not alone. This section should shed some light on why the transaction log behaves as it does.
SQL Server 2012 : Backing Up the Database (part 2) - Backing Up the Database with Code,Verifying the Backup with Code
The BACKUP command offers a few more options than Management Studio, and using the BACKUP command directly is useful for assembling SQL Server Agent jobs by hand, rather than with the Maintenance Plan Back Up Database Task.
SQL Server 2012 : Backing Up the Database (part 1) - Performing Backup with Management Studio
The first backup must be a full database backup to begin the backup chain. You can perform a database backup from Management Studio, selecting the database to be backed up.
SQL Server 2012 : Executing Your Queries (part 2) - SQLOS - CPU Nodes, Schedulers, Tasks, Workers, Threads
A CPU node is a logical collection of CPUs that share some common resource, such as a cache or memory. CPU nodes live below memory nodes in the SQLOS object hierarchy.
SQL Server 2012 : Executing Your Queries (part 1) - SQLOS - Memory Nodes
The SQLOS memory node is a logical container for memory associated with a node, which is a collection of CPUs with shared memory. This can be either a “real” memory node, if the server has a NUMA architecture, or an artificial grouping that you created as a “soft” NUMA configuration.
SQL Server 2012 : Query Plans (part 3) - Reading Query Plans
Because you are looking at the inner workings of the Query Optimizer, and because this is a feature of SQL Server that is constantly evolving, installing any service pack or patch can alter the behavior of the Query Optimizer, and therefore display different results.
SQL Server 2012 : Query Plans (part 2) - Query Plan Operators
Join operators enable SQL Server to find matching rows between two tables. Prior to SQL Server 2005, there was only a single join type, the nested loop join, but since then additional join types have been added, and SQL Server now provides the three join types described in Table 1.
SQL Server 2012 : Query Plans (part 1)
Now that you have seen how your T-SQL is optimized, the next step is to look at the query plan that the Query Optimizer generated for it. There are several ways to view query plans, but perhaps the easiest is to view the graphical plan using SQL Server Management Studio.
