Planning the Storage Layout
Database Instance Storage Considerations
Chapter 266
Oracle Single Instance RDBMS
Single Instance Oracle databases can be used with all three SGeSAP
storage layout options. The setup for NFS and NFS Idle Standby
Clusters are identical.
Oracle databases in SGeSAP NFS and NFS Idle Standby Clusters
Oracle server directories reside below /oracle/<DBSID>. These
directories get shared via the database package
In addition, any SAP Application Server needs access to the Oracle client
libraries, including the Oracle National Language Support files (NLS)
shown in Table 2-7 NLS Files Default Location. The default location to
which the client NLS files get installed differs with the SAP kernel
release used:
It is important to notice, that there always is a second type of NLS
directory, called the “server” NLS directory. It gets created during
database or SAP Central System installations. The location of the server
NLS files is identical for all SAP kernel versions:
$ORACLE_HOME/common/nls/admin/data
The setting of the ORA_NLS[<nls_version>] variable in the
environments of <sid>adm and ora<sid> determines whether the client
or the server path to NLS is used. The variable gets defined in the
.dbenv_<hostname>.[c]sh files in the home directories of these users.
