SERVICE GUIDE APTUM DATABASE ADMINISTRATION PROGRAM SEPTEMBER 2019 OVERVIEW Aptum’s Database Administration (DBA) Program was designed to DBA Plan hours can be leveraged for all database-related activities help our customers reduce the cost of normal operation and the risk of detailed within this document, up to the allocation purchased. If you application and database downtime. require more hours than are purchased in a plan for a given month, any excess will be billed on an hourly basis at the standard Database Customers can work with Aptum’s Solutions Engineers and Certified Administration rate. Database Administrators to obtain assistance with everything from database engine configuration, performance optimization, clustering Included Database Platforms: administration, and replication administration. Microsoft SQL Server To help you achieve your performance goals, we offer our DBA plans in MySQL/MariaDB/Percona block-hour increments: 4 hours* * Hours are monthly and renew at the 1st of each calendar month and do not roll over. Overage rates are applicable only after block hours are consumed. All hours are 8 hours* applicable to the entire solution not per server. 12 hours* 20 hours* THE NEED FOR DATABASE ADMINISTRATION Most applications—especially those that support enterprise processes enable e-commerce, or facilitate collaboration—are database-intensive and demand optimal performance from the database. Applications and database queries may utilize very lean and elegant code, but the structure and configuration of your databases can be a detriment to high performance. There are dozens, sometimes hundreds, of configuration settings that need to be optimally tuned to enhance database performance. When the database is installed, most configuration defaults are applied automatically. -

How to Conduct Transaction Log Analysis for Web Searching And
Search Log Analysis: What is it; what’s been done; how to do it Bernard J. Jansen School of Information Sciences and Technology The Pennsylvania State University 329F IST Building University Park, Pennsylvania 16802 Email: [email protected] Abstract The use of data stored in transaction logs of Web search engines, Intranets, and Web sites can provide valuable insight into understanding the information-searching process of online searchers. This understanding can enlighten information system design, interface development, and devising the information architecture for content collections. This article presents a review and foundation for conducting Web search transaction log analysis. A methodology is outlined consisting of three stages, which are collection, preparation, and analysis. The three stages of the methodology are presented in detail with discussions of goals, metrics, and processes at each stage. Critical terms in transaction log analysis for Web searching are defined. The strengths and limitations of transaction log analysis as a research method are presented. An application to log client-side interactions that supplements transaction logs is reported on, and the application is made available for use by the research community. Suggestions are provided on ways to leverage the strengths of, while addressing the limitations of, transaction log analysis for Web searching research. Finally, a complete flat text transaction log from a commercial search engine is available as supplementary material with this manuscript. Introduction Researchers have used transaction logs for analyzing a variety of Web systems (Croft, Cook, & Wilder, 1995; Jansen, Spink, & Saracevic, 2000; Jones, Cunningham, & McNab, 1998; Wang, 1 of 42 Berry, & Yang, 2003). Web search engine companies use transaction logs (also referred to as search logs) to research searching trends and effects of system improvements (c.f., Google at http://www.google.com/press/zeitgeist.html or Yahoo! at http://buzz.yahoo.com/buzz_log/?fr=fp- buzz-morebuzz). -

Database Management Systems Introduction Transaction ACID
Introduction What is Concurrent Process (CP)? • Multiple users access databases and use computer Database Management systems simultaneously. • Example: Airline reservation system. Systems œ An airline reservation system is used by hundreds of travel agents and reservation clerks concurrently. Transaction, Concurrency and Why Concurrent Process? Recovery • Better transaction throughput and response time • Better utilization of resource Adapted from Lecture notes by Goldberg @ Berkeley Transaction ACID Properties of transaction • What is Transaction? • Atomicity: Transaction is either performed in its entirety or not performed at all, this should be DBMS‘ • A sequence of many actions which are responsibility considered to be one atomic unit of work. • Consistency: Transaction must take the database • Basic operations a transaction can include from one consistent state to another if it is executed in —actions“: isolation. It is user‘s responsibility to insure consistency œ Reads, writes • Isolation: Transaction should appear as though it is œ Special actions: commit, abort being executed in isolation from other transactions • Durability: Changes applied to the database by a committed transaction must persist, even if the system fail before all changes reflected on disk Concurrent Transactions Schedules • What is Schedules œ A schedule S of n transactions T1,T2,…Tn is an ordering of the B B operations of the transactions subject to the constraint that, for each transaction Ti that participates in S, the operations of Ti in Smust CPU2 A appear in the same order in which they occur in Ti. CPU A 1 œ Example: Sa: r1(A),r2(A),w1(A),w2(A), a1,c2; CPU1 T1 T2 time Read(A) Read(A) t1 t2 t1 t2 Write(A) interleaved processing parallel processing Write(A) Abort T1 Commit T2 1 Oops, something‘s wrong Another example • Reserving a seat for a flight • Problems can occur when concurrent transactions execute in an uncontrolled manner. -
Data Definition Language (Ddl)
DATA DEFINITION LANGUAGE (DDL) CREATE CREATE SCHEMA AUTHORISATION Authentication: process the DBMS uses to verify that only registered users access the database - If using an enterprise RDBMS, you must be authenticated by the RDBMS - To be authenticated, you must log on to the RDBMS using an ID and password created by the database administrator - Every user ID is associated with a database schema Schema: a logical group of database objects that are related to each other - A schema belongs to a single user or application - A single database can hold multiple schemas that belong to different users or applications - Enforce a level of security by allowing each user to only see the tables that belong to them Syntax: CREATE SCHEMA AUTHORIZATION {creator}; - Command must be issued by the user who owns the schema o Eg. If you log on as JONES, you can only use CREATE SCHEMA AUTHORIZATION JONES; CREATE TABLE Syntax: CREATE TABLE table_name ( column1 data type [constraint], column2 data type [constraint], PRIMARY KEY(column1, column2), FOREIGN KEY(column2) REFERENCES table_name2; ); CREATE TABLE AS You can create a new table based on selected columns and rows of an existing table. The new table will copy the attribute names, data characteristics and rows of the original table. Example of creating a new table from components of another table: CREATE TABLE project AS SELECT emp_proj_code AS proj_code emp_proj_name AS proj_name emp_proj_desc AS proj_description emp_proj_date AS proj_start_date emp_proj_man AS proj_manager FROM employee; 3 CONSTRAINTS There are 2 types of constraints: - Column constraint – created with the column definition o Applies to a single column o Syntactically clearer and more meaningful o Can be expressed as a table constraint - Table constraint – created when you use the CONTRAINT keyword o Can apply to multiple columns in a table o Can be given a meaningful name and therefore modified by referencing its name o Cannot be expressed as a column constraint NOT NULL This constraint can only be a column constraint and cannot be named. -

Transaction Processing System
Transaction processing system From Wikipedia, the free encyclopedia (Redirected from Transaction processing systems) It has been suggested that this article or section be merged into Transaction processing. (Discuss) Proposed since November 2012. Transaction processing is a style of computing that divides work into individual, indivisible operations, called transactions.[1] Atransaction processing system (TPS) or transaction server is a software system, or software/hardware combination, that supports transaction processing.

Designed to process up to 83,000 transactions a day, the system ran on two IBM 7090 computers. SABRE was migrated to IBM System/360computers in 1972, and became an IBM product first as Airline control Program (ACP) and later as Transaction Processing Facility (TPF). In addition to airlines TPF is used by large banks, credit card companies, and hotel chains. -
