Installationsanleitung Linux/Oracle

Linux Installation (SLES 10.2 / 11.2)

Basisinstallation

• Hardware bereitstellen (Blech ohne Multipath!) (withiscssi=1)
• Installation Physikalischen Server auswählen
• Festplatten konfigurieren
• Software auswählen (mit KDE, Entwicklungsumgebung, Oraclevorbereitung, ohne Gnom, Druckerumgebung, und Webbasierende Unternehmensanwendung)
• Netzwerk konfigurieren
• Lokale Userverwaltung verwenden
• User / user anlegen UID 1000
• ssh konfigurieren

ggf. Multipath installieren

• modprobe dm_multipath
• Definition in fstab und boot.menu überprüfen (/dev/disk/by-id/…)
• Kernelfile (qla…, dm_multipath)
• Autostart multipathd

Installationsverzeichnis verknüpfen

• Mountpoint erstellen
• Fstab bearbeiten (/etc/fstab)

Zusätzliche Software installieren

Remotezugriff (NX-Nomachine) installieren

• Client entpacken (/usr)
• Node entpacken
• Server entpacken
• Setup aufrufen
• Konfigurationsfile kopieren
• nxserver –useradd nxadmin –system –administrator --uid 5002
• nxserver –userenable nxadmin

Bei Problemen mit der Authentifizierung die SSH-Settings überprüfen.

  nxserver --usercheck nxadmin

Oracle Installation

Vorbereitung

• User oracle aktivieren, UserID auf 5001 setzen, Homeverzeichnis ändern, Gruppe dba auf 5000 setzen
• Festplatten hinzufügen / Berechtigungen oracle:dba setzen

/dev/sdc1 /opt/oracle

/dev/sde1 /backup

• Datei /etc/profile.d/oracle.sh (oracle.csh) anpassen

Oraclesetup

• System neu starten
• Datei /etc/SuSE-release kopieren und Einträge von 11 auf 9 setzen
• ggf. Oracle Paket 102 (cpio –idmv < …) entpacken
• runInstaller ausführen und Standard Edition ohne Datenbank installieren. Gruppe dba wenn nötig auswählen, sonst sind keine Anpassung notwendig. (1 Fehler kann ignoriert werden)
• ggf. Oracle Paket
