The Template Explorer window is used to open a list of templates that allows users to create objects in the database. This template includes files that contain SQL script to create objects. Users use this template to create tables, views, indexes, stored procedures, trigger and functions.
When any database is created in SQL Server then at least one file is created to store the data and system tables and another file to hold the transaction log. The transaction log is stored in one or more files with a default extension of .ldf.
If the size of the transaction log file is not specified, then the transaction log will be resized to 25 percent of the size of the data file. This transaction log file is used to store all the transactions and modifications done on the database. The transaction log file is very useful in performing the backup and restore process of the database.
The sp_update_agent_profile stored procedure is used to update the profile used by a specified agent.
The syntax for using this stored procedure is as follows:
sp_update_agent_profile [@agent_type=] agent_type, [ @agent_id= ] agent_id, [@profile_id= ] profile_id
Arguments:
[@agent_type=] ‘agent_type’: It is the type of agent and its type is int.
[@agent_id= ] ‘agent_id’: It is the type of ID and its type is int.
[@profile_id= ] ‘profile_id’: It is the ID of the profile that should be used by the agent. Its type is int.
The dta utility is the command prompt edition of Database Engine Tuning Advisor. The dta utility allows users to use Database Engine Tuning Advisor functionality in applications and scripts.
The dta utility analyzes a workload and suggests physical design structures to enhance server performance for that workload. The workload can be a SQL Server Profiler trace file or a table, or a Transact-SQL script. Physical design structures comprise indexes, indexed views, and partitioning. After examining a workload, the dta utility produces a suggestion for the physical design of databases and can produce the necessary script to implement the suggestion.
Native mode is the default mode for report server instances. In this mode, a report server is a stand-alone application server that provides all viewing, management, processing, and delivery of reports, and report models. A user can install a native mode report server that is configured during setup or configure it for native mode operations after Setup is finished.
SharePoint integrated mode enables the integration of Reporting Services with the SharePoint databases and security model. These features become available when a user configures a report server to run within a larger deployment of a SharePoint 3.0 product or technology. This mode requires additional software and configuration. It also necessitates that a report server instance be dedicated for integrated operations. The benefit of doing this is a rich level of integration that allows a user to access and manage report server content types using the application pages and data stores of a SharePoint Web application.
