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

...and that's probably because of some reason in the operating system? That's exactly what I had on a freshly installed SAP Solution Manager (DB: Oracle 10.2.0.2, OS: SUSE Linux Enterprise Server 10, architecture: Linux x86_64)...

The SAP-Support told me taht the reason was a name conflict between the Novell package "sapinit" and the SAP system script "startsapserv". As a workaround until a new version of "sapinit" I should uninstall this package.

Oh, OK :-( But the software should start automatically on system start, so I wrote my own startup script:

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

# Figure out what to do, and do it;-)

        for SAPSID in $MYSAP_SYSTEMS; do
            SIDBIG=$(echo $SAPSID | tr /a-z/ /A-Z/)
            SIDSML=$(echo $SAPSID | tr /A-Z/ /a-z/)
            SIDADM="${SIDSML}adm"
            ORASID="ora${SIDSML}"
            su - $ORASID -c "/oracle/$SIDBIG/102_64/bin/lsnrctl start"
            su - $SIDADM -c "/sapmnt/$SIDBIG/exe/startsap"
        done
        rc_status -v
        ;;

        for SAPSID in $MYSAP_SYSTEMS; do
            SIDBIG=$(echo $SAPSID | tr /a-z/ /A-Z/)

            SIDADM="${SIDSML}adm"

            SAPPROCS=$(ps ax | grep "dw.sap$SIDBIG" | grep -v grep | wc -l)
            ORAPROCS=$(ps ax | grep "oracle$SIDBIG" | grep -v grep | wc -l)
            JVAPROCS=$(ps ax | grep jlaunch | grep $SIDBIG | grep -v grep | wc -l)

        echo "Usage: $0 {start|status|stop|restart|try-restart}"

And finally
<code bash>
ln -s /etc/init.d/mysap /usr/sbin/rcmysap
insserv mysap
</code>
and everything is fine.

BTW, the configuration file ''/etc/sysconfig/mysap'' looks like this:
<code bash>
## Path:        Productivity/Other
## Description: Parameters for SAP software on this machine
## Config:      mysap
#
# This file defines some parameters.
#
# There are no default values, since they highly depend on the
# individual system.
#

## Type:                string
## Default:             ""
## Config:              ""
#
# the SAP systems to be controlled. Multiple systems separated by space.
