Oracle Enterprise Manager 12c Command-Line Interface shows how to use Enterprise Manager’s powerful scripting language to automate your database administration work and save time by scripting routine tasks, and then executing those scripts across collections of databases and instances in your environment. This book is chock full of ready-made scripting examples contributed by the authors and leading members of the community. For example, you'll find scripts and examples of commands to: Remove an Enterprise Manager agent and its related targets Quickly create administrator accounts that are fully-configured with pre-expired passwords and all needed roles Invoke batch files to execute sequences of related commands with consistency against multiple targets Batch create large groups of user logins with a single command and more! The Enterprise Manager Command Line Interface (EM CLI) is the administrator's key to unlocking the power of Enterprise Manager 12c (EM12c) with scalability, repeatability, and confidence. In previous versions, most administrators ventured into the command-line interface only with the assistance of Oracle Support. But now there are many features in EM12c that are accessible only from the command-line. This is far from a disadvantage! Enterprise Manager is now a powerful tool for automation in the hands of a skilled database administrator. Enterprise Manager scripting offers potential for all administrators who manage Oracle’s enterprise-level products in their environment. You can automate from the smallest, single-instance configuration all the way up to a broadly distributed enterprise-level rollout having database instances strewn across broad geographical distributions. The power of the EM CLI returns the administrator to the golden age, where the entire environment, from database to application to infrastructure, can often be managed from this powerful command line tool secured by the robust Enterprise Manager framework. Brings a golden-age of automation to Oracle Database administrators Provides ready-made scripts contributed by leading members of the community Covers advanced techniques involving Jython and Python

grep kurz & gut ist die erste deutschsprachige Befehlsreferenz zu grep, dem mächtigen Such- und Filterungswerkzeug unter Unix. Jeder, der sich ausführlich zu den Möglichkeiten, die in grep stecken, informieren möchte, ist mit diesem Buch bestens bedient. Er erfährt, wie viele alltägliche Aufgaben mit grep ausgeführt werden können, von der Mail-Filterung über geschicktes Log-Management bis hin zur Malware-Analyse. Der Befehl grep stellt viele verschiedene Möglichkeiten bereit, Textstrings in einer Datei oder einem Ausgabestream zu finden. Diese Flexibilität macht grep zu einem mächtigen Tool, um das Vorhandensein von Informationen in Dateien zu ermitteln. Im Allgemeinen ist der Befehl grep nur dafür gedacht, Textausgaben oder Textdateien zu durchsuchen. Sie können auch Binärdateien (oder andere Nicht-Textdateien) durchsuchen, aber das Tool ist in dem Fall eingeschränkt. Tricks zum Durchsuchen von Binärdateien mit grep (also die Verwendung von String-Befehlen) werden ebenso in grep kurz & gut aufgezeigt. Sollte der Leser bereits mit der Arbeit mit grep vertraut sein, hilft ihm grep kurz & gut dabei, seine Kenntnisse aufzufrischen und mit grep besonders effizient zu arbeiten. Für grep-Einsteiger ist das vorliegende Buch eine hervorragende Möglichkeit, grep von Grund auf zu lernen und klug anzuwenden.
