Morton University of Pennsylvania Follow this and additional works at: https://repository.upenn.edu/cis_reports Recommended Citation Richard P. Morton, "On-Line Computing With a Hierarchy of Processors", . December 1968. University of Pennsylvania Department of Computer and Information Science Technical Report No. MS-CIS-69-13. This paper is posted at ScholarlyCommons. https://repository.upenn.edu/cis_reports/804 For more information, please contact [email protected]. On-Line Computing With a Hierarchy of Processors Abstract Time shared computer systems have been based upon the two techniques of multiprogramming and swapping. Multiprogramming is based on restricting each program to a portion of the total computer memory. Swapping requires considerable overhead time for loading and unloading programs. To alleviate the size restriction due to multiprogramming, segmentation is employed, resulting in fact in vastly increased swapping. A new system architecture is proposed for time shared computing that alleviates the high overhead or program size restriction. It utilizes a hierarchy of processors, where each processor is assigned tasks on the basis of four factors: interactive requirements, frequency of use, execution time, and program length. In order to study the hierarchical approach to system architecture, the Moore School Problem Solving Facility (MSPSF) was built and used. The study of the manner of operation and the reactions of the users clarified and defined the Hierarchy of Processors system architecture. The Moore School Problem Solving Facility was implemented on second generation equipment, the IBM 7040, and therefore it is not possible to adequately compare the efficiency with third generation computers operating in a swapping mode. -
Perl DBI API Reference
H Perl DBI API Reference This appendix describes the Perl DBI application programming interface. The API consists of a set of methods and attributes for communicating with database servers and accessing databases from Perl scripts. The appendix also describes MySQL-specific extensions to DBI provided by DBD::mysql, the MySQL database driver. I assume here a minimum version of DBI 1.50, although most of the material applies to earlier versions as well. DBI 1.50 requires at least Perl 5.6.0 (with 5.6.1 preferred). As of DBI 1.611, the minimum Perl version is 5.8.1. I also assume a minimum version of DBD::mysql 4.00. To determine your versions of DBI and DBD::mysql (assuming that they are installed), run this program: #!/usr/bin/perl # dbi-version.pl - display DBI and DBD::mysql versions use DBI; print "DBI::VERSION: $DBI::VERSION\n"; use DBD::mysql; print "DBD::mysql::VERSION: $DBD::mysql::VERSION\n"; If you need to install the DBI software, see Appendix A , “Software Required to Use This Book.” Some DBI methods and attributes are not discussed here, either because they do not apply to MySQL or because they are experimental methods that may change as they are developed or may even be dropped. Some MySQL-specific DBD methods are not discussed because they are obsolete. For more information about new or obsolete methods, see the DBI or DBD::mysql documentation, available at http://dbi.perl.org or by running the following commands: % perldoc DBI % perldoc DBI::FAQ % perldoc DBD::mysql The examples in this appendix are only brief code fragments. -
Accessing DB from Programming Languages
Accessing DB from programming languages JDBCJDBC andand ODBCODBC • API (application-program interface) for a program to interact with a database server • Application makes calls to – Connect with the database server – Send SQL commands to the database server – Fetch tuples of result one-by-one into program variables • ODBC (Open Database Connectivity) works with C, C++, C#, and Visual Basic – Other API’s such as ADO.NET sit on top of ODBC • JDBC (Java Database Connectivity) works with Java JDBCJDBC • JDBC is a Java API for communicating with database systems supporting SQL. • JDBC supports a variety of features for querying and updating data, and for retrieving query results. • JDBC also supports metadata retrieval, such as querying about relations present in the database and the names and types of relation attributes. • Model for communicating with the database: – Open a connection – Create a “statement” object – Execute queries using the Statement object to send queries and fetch results – Exception mechanism to handle errors JDBCJDBC CodeCode public static void JDBCexample(String dbid, String userid, String passwd) { try { Class.forName ("oracle.jdbc.driver.OracleDriver"); Connection conn = DriverManager.getConnection( "jdbc:oracle:thin:@db.yale.edu:2000:univdb", userid, passwd); Statement stmt = conn.createStatement(); … Do Actual Work …. stmt.close(); conn.close(); } catch (SQLException sqle) { System.out.println("SQLException : " + sqle); } } JDBCJDBC CodeCode (Cont.)(Cont.) • Update to database try { stmt.executeUpdate( "insert -

Netezza EOL: IBM IAS Is a Flawed Upgrade Path Netezza EOL: IBM IAS Is a Flawed Upgrade Path
Author: Marc Staimer WHITE PAPER Netezza EOL: What You’re Not Being Told About IBM IAS Is a Flawed Upgrade Path Database as a Service (DBaaS) WHITE PAPER • Netezza EOL: IBM IAS Is a Flawed Upgrade Path Netezza EOL: IBM IAS Is a Flawed Upgrade Path Executive Summary It is a common technology vendor fallacy to compare their systems with their competitors by focusing on the features, functions, and specifications they have, but the other guy doesn’t. Vendors ignore the opposite while touting hardware specs that mean little. It doesn’t matter if those features, functions, and specifications provide anything meaningfully empirical to the business applications that rely on the system. It only matters if it demonstrates an advantage on paper. This is called specsmanship. It’s similar to starting an argument with proof points. The specs, features, and functions are proof points that the system can solve specific operational problems. They are the “what” that solves the problem or problems. They mean nothing by themselves. Specsmanship is defined by Wikipedia as: “inappropriate use of specifications or measurement results to establish supposed superiority of one entity over another, generally when no such superiority exists.” It’s the frequent ineffective sales process utilized by IBM. A textbook example of this is IBM’s attempt to move their Netezza users to the IBM Integrated Analytics System (IIAS). IBM is compelling their users to move away from Netezza. In the fall of 2017, IBM announced to the Enzee community (Netezza users) that they can no longer purchase or upgrade PureData System for Analytics (the most recent IBM name for its Netezza appliances), and it will end-of-life all support next year. -
