Release 2 Dependency on ODS-5 Disk Structure
In general, ODS-5 format allows VMS to support Microsoft Windows file naming
formats. Longer file names, additional character support, and the ability to have
lowercase and mixed-case file names are some of the features supported on ODS-5
disks.
The disks on which the Oracle code tree resides must be formatted in Files-11
On-Disk Structure Level 5 (ODS-5) format. This is the disk to which the VMS
logicals
ora_root, ora_rootdir,
and
oracle_home
will point. The
directory that is referenced by these logicals is the parent directory for all Oracle
RDBMS software, such as APACHE, CTX, INSTALL, NETCONFIG, RDBMS, UTIL,
and so forth. The disks on which Oracle database files reside can be formatted as
either ODS-2 or ODS-5.
Oracle Note 205630.1 can be viewed at Oracle MetaLink. Alternatively, use the
search function and search for "ODS-5" for more information.
Precautions

Caution:
Oracle Corporation
STRONGLY
urges you to read the
OpenVMS Guide to Extended File Specifications
PRIOR
to
changing the structure of any disk. This guide discusses ODS-2
and ODS-5 formats in much more detail and has important
information that you must understand and follow.
