HP Serviceguard Extension for SAP (SGeSAP) External Application Server Host Configuration, Set -u

If storage layout option 1 is used, create all SAP instance directories below /export as specified in Chapter 2.

For 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 /exportas specified in Chapter 2.

For example:

su - sqd<sid>

mkdir -p /export/sapdb/programs

mkdir -p /export/sapdb/data

mkdir -p /export/var/spool/sql/ini

exit

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. It is likely that 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 3-5 - Relocatable IP Address Information to record the addresses.

Table 3-5 Relocatable IP Address Information

name/aliases IP address

Installation Step: IS310

Configure /etc/nsswitch.conf to avoid problems.

If you use DNS:

For example:

hosts: files[NOTFOUND=continue UNAVAIL=continue TRYAGAIN=continue]dns

Installation Step: IS330

In some older SAP releases, during installation SAP appends some entries to the standard .profile files in the user home directories instead of using a new file defined by the SAP System. On HP-UX, by default, there is the following in the given profiles:

set -u

This confuses the .dbenv*.sh and .sapenv*.sh files of the SAP System. They fail during execution if the environment is not setup properly. Using SGeSAP the package startup fails trying to bring up the database.

Search the .profile of <sid>adm and remove the set -u, if found.
