Installation guide

The transport directory /usr/sap/trans should also be exported via NFS according to your SAP

landscape.

6.2.3.4 Before Starting the SAP Installation

Before installing SAP NetWeaver, mount all the file necessary systems. Be conscious of the

overmount-effect by mounting the hierarchically highest directories first.

6.2.4 Installation with sapinst

When starting the SAP installation tool sapinst, specify the virtual host name.

sapinst SAPINST_USE_HOSTNAME=<virtual hostname>

For each SAP and database instance installed, choose the installation option "High-

Availability System" as it is described in the SAP installation guide.

6.2.5 lnstallation Post-Processing

6.2.5.1 Users, Groups and Home Directories

Create users and groups on the second node as they were created by the SAP installation on

the first node. Use the same user ID and group ID.

Depending on the Installation Master CD that was used for the SAP installation, the login

profiles for the SAP administrator user (<sid>adm) and the database administrator user might

be different. In older and non-HA installations the user login profiles look similar to this one:

.sapenv_hostname.csh

Using the host name in the user login profiles is a problem in a highly available environment.

By default the profiles .login, .profile and .cshrc will search for two types of user login profiles:

first for the one including the local host name (e.g., .dbenv_hostname.csh) and then for a

version without the host name included. Latest versions of the InstMaster CDs will install both

versions of the user login profiles. This might lead to some confusion for the administrator,

regarding which version is used in which case. We recommend removing all user login

profiles that include a host name in the file name. Do this for both users: the SAP

administrator <sid>adm and the database administrator user.

6.2.5.2 Synchronizing Files and Directories

Copy the /etc/services or its values that were adjusted by sapinst (see SAP related entries at

the end of the file) to all nodes.

MaxDB

Copy the file /etc/opt/sdb and the directory structure /usr/spool/sql to the GFS mount point

/sapdb and create links to them.
