Installation Step: IS280
If storage layout option 1 is used, create all SAP instance directories below /export as specified
in chapter 2 .
Example:
su - <sid>adm
mkdir -p /export/sapmnt/<SID>
mkdir -p /export/usr/sap/trans
exit
MaxDB Database Step: SD290
Create all MaxDB directories below /export as specified in chapter 2 .
Example:
su - sqd<sid>
mkdir -p /export/sapdb/programs
mkdir -p /export/sapdb/data
mkdir -p /export/var/spool/sql/ini(MaxDB < 7.8 only)
mkdir -p /export/sapdb/client(MaxDB >= 7.8 only)
exit
MaxDB Database Step (>=7.8 only): SD295
Switch off autostart for installation specific x_server
With “isolated installation” each 7.8 database has its own associated vservers. The general vserver
still exists for older databases and to forward requests to the vserver of a 7.8 database. The startup
of the generic vserver will also startup the installation-specific vserver out of the DB specific bin
directory (while stopping of the generic won’t stop the specific ones). When running more than
one 7.8 database in a clustered environment this startup behavior may lead to error messages
(because the filesystem of the other DB isn’t mounted) or even busy filesystems belonging to the
other database. Therefore, it is recommended to switch the autostart feature off when running more
than one >= 7.8 database. However, keep in mind that SAP’s startdb currently relies on autostart
being switched on and doesn’t explicitly start the DB specific vserver.
Autostart can be switched off by editing the [Params-/sapdb/<DBSID>/db] section in
/sapdb/data/config/Installations.ini: Set XserverAutostart to no (default=yes).
Installation Step: IS300
Each package needs at least one relocatable IP address to be specified .
In case there is a distinction between front-end, server, and LANs. At least two addresses are
needed per package. Dedicated heartbeat LANs would require additional addresses. Add all
relocatable IP address information to /etc/hosts. Use Table 19 (page 68) to record the
addresses.
