1 25$&/(J'DWD*XDUGDXIGHU.RPPDQGR]HLOH 8ZH+HVVH3ULQFLSDO,QVWUXFWRU25$&/(8QLYHUVLW\ Die folgende Anleitung ist als eine Ergänzung zu dem ORACLE University Kurs Oracle Database 10g: Data Guard Administration entstanden. Sie behandelt die Erzeugung und Verwaltung von Physical und Logical Standby Databases ohne Zuhilfenahme von ORACLE Grid Control. Die Anleitung ist entwickelt worden auf Red Hat Enterprise Linux AS release 4 (Nahant Update 2) Kernel EL on an i686, dürfte aber nahezu identisch auf allen zertifizierten Plattformen funktionieren. Die eingesetzte ORACLE Version ist Oracle Database 10g Enterprise Edition Release Es wird hier auf nur einem Server eine Primary Database, eine Physical und eine Logical Standby Database angelegt. Zu Test- und Demonstrationszwecken ist das gut geeignet; eine realistische Umsetzung würde natürlich 3 Rechner verlangen. Die Anleitung ist dazu aber leicht anpassbar; tatsächlich ist es sogar etwas schwieriger, alles auf einem Rechner anzulegen.
