Installation guide

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 could
differ. 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 an HA 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. The latest versions of the InstMaster CDs will install both versions of
the user login profiles. This could lead to some confusion for the administrator with regard to
which version is used in which case. The removal of all user login profiles (that include a host
name in the file name) is recommended. Do this for both the SAP administrator, <sid>adm, as
well as the database administrator user.
6.1.5.2 Synchronizing Files and Directories
Copy /etc/services or its values that were adjusted by sapinst (see SAP related entries at the
end of the file) to all other nodes.
MaxDB
Copy the file /etc/opt/sdb and the directory structure /usr/spool/sql to the other nodes.
Make the directories (with their content) /sapdb/programs/lib and /sapdb/programs/runtime
available even if the file system /sapdb is not mounted. To do so, mount /sapdb and copy the
directories /sapdb/programs/lib and /sapdb/programs/runtime to a temporary directory.
Unmount /sapdb and copy them locally to /sapdb/programs/lib and /sapdb/programs/runtime.
Do this on every node.
Oracle
Copy the files /etc/oratab and /etc/oraInst.loc to the other nodes.
Make the directory (with its content) /oracle/client/10x_64/instantclient available even if the
file system /oracle is not mounted. To do so, mount /oracle and copy the directory
/oracle/client/10x_64/instantclient to a temporary directory. Unmount /oracle and copy it
locally to /oracle/client/10x_64/instantclient. Do this on every node.
6.1.5.3 SAP Profiles
The most important SAP profile parameter for a clustered SAP system is SAPLOCALHOST.
After the installation with sapinst, ensure that all SAP instance profiles contain this parameter.
The value of the parameter must be the virtual host name specified during the installation.
