Note SQL Server 2012 Service Pack 1 was also made available on Microsoft Update on November 27, 2012. Mandatory SQL Server 2012 SP1 hotfixAfter you install SQL Server 2012 SP1, you may experience an issue in which Windows Installer starts repeatedly. This issue is described in the following article in the Microsoft Knowledge Base. This article includes a link to a downloadable hotfix that resolves the issue: Note It is mandatory that you install this hotfix after you install SQL Server 2012 SP1.
Error: 9002, Severity: 17, State: 4.The transaction log for database 'tempdb' is full due to 'ACTIVE_TRANSACTION'.Error: 3314, Severity: 21, State: 3.During undoing of a logged operation in database 'tempdb', an error occurred at log record ID (135:376:442). Typically, the specific failure is logged previously as an error in the Windows Event Log service. Restore the database or file from a backup, or repair the database.Error: 3449, Severity: 21, State: 1.SQL Server must shut down in order to recover a database (database ID 2). The database is either a user database that could not be shut down or a system database. Restart SQL Server. If the database fails to recover after another startup, repair or restore the database.SQL Trace was stopped due to server shutdown. Trace ID = '1'.

This issue occurs if the size of the tempdb log file is not enough to handle tempdb workload, and the auto growth of the log file is set to Off. If a rollback fails in tempdb because of limited space, SQL Server crashes. This hotfix enables a more precise calculation of reserved space when the log runs out of space. This hotfix also helps avoid rollback failure in tempdb by enabling the tempdb log grow temporarily. These changes help prevent server crashes.

SQL Server 2012 has made many changes to the memory manager to govern the SQL Server memory consumption in efficient way compared with earlier versions. Important changes to SQL Server 2012 memory which every DBA should be aware of is documented in this blog. If you are not familiar with the SQL Server memory architecture of earlier versions I would recommend reading THIS ARTICLE before you continue with changes in Denali memory manager.

This unofficial build chart lists all of the known Service Packs (SP), Cumulative Updates (CU), patches, hotfixes and other builds of MS SQL Server 2022, 2019, 2017, 2016, 2014, 2012, 2008 R2, 2008, 2005, 2000, 7.0, 6.5 and 6.0 that have been released.
There were several problems with this combination of components. First was the mismatch between SQL Server 2012 Standard Edition and the size of the EC2 instance. Second was the age and relatively low performance of the EC2 I3 instance type host processor.
To make matters worse, if you install SQL Server 2012 Standard Edition on a VM with 64 vCPUs in two sockets, all of your 32 available license limit vCPUs will be running on the first NUMA node. No schedulers will be running on the second NUMA node. You can correct the NUMA node imbalance with an ALTER SERVER CONFIGURATION command, as I discuss here.
SQL Server 2012 Standard Edition can only use 64GB of RAM per instance for the SQL Server buffer pool. Other components besides the buffer pool will use some memory, so ideally your VM would have at least 96GB or 128GB of RAM.
Remember, SQL Server 2012 Standard Edition can only use half of the vCPUs for this VM, so SQL Server only has 50% of the total VM CPU capacity available. This means that this VM would only have the equivalent CPU-Z multi-thread score of 6,444.1 for SQL Server 2012 Standard Edition.
Has anyone else experienced this and if yes what was the solution? I've identified that this is related to a SQL instance called "Monitor" on the server (it's just the one server we have), but I'm unable to login to that instance via SQL management Studio to check any of the details. There's no documentation from my predecessor and I've not used Lync before so I'm having to fumble my way through, any help would be greatly appreciated.
Note that you must use the 64-bit editions of these databases; 32-bit versions of SQL Server cannot be used as the backend store for monitoring. Likewise, Lync Server 2013 does not support the Express Editions of SQL Server 2008 or SQL Server 2012.
Viewing sessions that view unprepared files or go into deep zoom mode require the additional hardware resources listed above. On average, between 10% and 25% of the clients connected to a server fall into this category, and these are the ones that should be taken into account.
To give your Automation Engine with 50 clients system viewing capabilities on unprepared files, you should add additional hardware resources for viewing. If you expect 8 simultaneous viewing sessions (8 single file sessions or 4 compare sessions), add an additional 4 processor cores and 12 GB RAM to the standard requirements.
All Esko applications running on Windows OS can use data that is available on network shares. For Automation Engine to perform according to expectations, these shares need to be on NTFS volumes on Windows file servers (with no folders enabled for case-sensitive file names). It is recommended to use Windows Server 2012, Windows Server 2012 R2, Windows Server 2016 or Windows Server 2019 as file server (preferably the same version as for the Automation Engine server).
The protocol layer implements the external interface to SQL Server. All operations that can be invoked on SQL Server are communicated to it via a Microsoft-defined format, called Tabular Data Stream (TDS). TDS is an application layer protocol, used to transfer data between a database server and a client. Initially designed and developed by Sybase Inc. for their Sybase SQL Server relational database engine in 1984, and later by Microsoft in Microsoft SQL Server, TDS packets can be encased in other physical transport dependent protocols, including TCP/IP, named pipes, and shared memory. Consequently, access to SQL Server is available over these protocols. In addition, the SQL Server API is also exposed over web services.[9]
Microsoft SQL Server also allows user-defined composite types (UDTs) to be defined and used. It also makes server statistics available as virtual tables and views (called Dynamic Management Views or DMVs). In addition to tables, a database can also contain other objects including views, stored procedures, indexes and constraints, along with a transaction log. A SQL Server database can contain a maximum of 231 objects, and can span multiple OS-level files with a maximum file size of 260 bytes (1 exabyte).[9] The data in the database are stored in primary data files with an extension .mdf. Secondary data files, identified with a .ndf extension, are used to allow the data of a single database to be spread across more than one file, and optionally across more than one file system. Log files are identified with the .ldf extension.[9]
SQL Server also allows stored procedures to be defined. Stored procedures are parameterized T-SQL queries, that are stored in the server itself (and not issued by the client application as is the case with general queries). Stored procedures can accept values sent by the client as input parameters, and send back results as output parameters. They can call defined functions, and other stored procedures, including the same stored procedure (up to a set number of times). They can be selectively provided access to. Unlike other queries, stored procedures have an associated name, which is used at runtime to resolve into the actual queries. Also because the code need not be sent from the client every time (as it can be accessed by name), it reduces network traffic and somewhat improves performance.[32] Execution plans for stored procedures are also cached as necessary.
T-SQL (Transact-SQL) is Microsoft's proprietary procedural language extension for SQL Server. It provides REPL (Read-Eval-Print-Loop) instructions that extend standard SQL's instruction set for Data Manipulation (DML) and Data Definition (DDL) instructions, including SQL Server-specific settings, security and database statistics management.
It exposes keywords for the operations that can be performed on SQL Server, including creating and altering database schemas, entering and editing data in the database as well as monitoring and managing the server itself. Client applications that consume data or manage the server will leverage SQL Server functionality by sending T-SQL queries and statements which are then processed by the server and results (or errors) returned to the client application. For this it exposes read-only tables from which server statistics can be read. Management functionality is exposed via system-defined stored procedures which can be invoked from T-SQL queries to perform the management operation. It is also possible to create linked Servers using T-SQL. Linked servers allow a single query to process operations performed on multiple servers.[33]
The SQL Server Machine Learning services operates within the SQL server instance, allowing people to do machine learning and data analytics without having to send data across the network or be limited by the memory of their own computers. The services come with Microsoft's R and Python distributions that contain commonly used packages for data science, along with some proprietary packages (e.g. revoscalepy, RevoScaleR, microsoftml) that can be used to create machine models at scale. 2ff7e9595c
