+====== SAP will nicht starten ======
+...und zwar aus Gründen, die vermutlich am Betriebssystem liegen? Genau das lag bei einem neu installierten SAP Solution Manager (DB: Oracle 10.2.0.2, OS: SUSE Linux Enterprise Server 10, Architektur: Linux x86_64) vor...
+Der SAP-Support teilte mir mit, dass das Problem aus einem Namenskonfikt zwischen dem Novell-Paket "sapinit" und dem SAP-Systemscript "startsapserv" resultiere. Workaround bis zur Freigabe eines geänderten "sapinit" sei es, das Paket ganz zu deinstallieren.
+Naja, wenn es weiter nichts ist... :-( Aber schließlich sollte die Software bei einem Rechnerstart automatisch starten, also habe ich ein eigenes rc-Script geschrieben:
+<code bash>
+#! /bin/bash
+#
+# /etc/init.d/mysap
+#
+#   and its symbolic link
+#
+# /usr/sbin/rcmysap

+# Should-Start:   sysstat

+# Default-Start:  3 5
+# Default-Stop:   0 1 2 6
+# Short-Description:    Control script for SAP systems

+# Reset status of this service
+rc_reset
+# Figure out what to do, and do it ;-)

+Zum Abschluss noch ein

+## Type:                string

+## Config:              ""
+#
+# the SAP systems to be controlled. Multiple systems separated by space.
