====== SAP won't start ======

...and that is because of some reasons that are caused by the operating system? Exactly that was the case with a new installed SAP Solution Manager 4.0 (DB: Oracle, OS: SLES 10 x86_64)...

SAP support told me the cause for this problem was a name conflict between the SLES package sapinit and the SAP command "startsapserv". As a workaround I had to uninstall the package "sapinit".

Well, this is not hard to do (''rpm -e sapinit''). But the software had to start together with the system, so I wrote a startup script on my own:

<code bash>
#! /bin/bash
#
# /etc/init.d/ufzsap
#
#   and its symbolic link
#
# /usr/sbin/rcufzsap
#

BTW, the mentioned ''/etc/sysconfig/ufzsap'' contains only the line
<code bash>
UFZSAP_SYSTEMS="SID"
</code>
where SID is the SAP system ID for the installed SolMan. Multiple Systems may be given separated by blanks.

Afterwards, I entered
<code bash>
ln -s /etc/init.d/ufzsap /usr/sbin/rcufzsap
insserv ufzsap
</code>
and everything went smooth!
