3.5.1 MxDB-Oracle-HiAv Installation and Administration Guide

Chapter 1: Install MxDB-Oracle-HiAv 3

MxDB-Oracle-HiAv depends on the standard Optimal Flexible

Architecture (OFA) layout of the Oracle software. Databases created with

the Database Configuration Assistant (DBCA) will generally possess the

layout required for MxDB-Oracle-HiAv. You will need to comply with

two configuration requirements:

•

ORACLE_HOME/dbs. Appropriate database configuration files (either

an init.ora or a spfile.ora) must exist in this directory for any database

managed by MxDB-Oracle-HiAv. DBCA creates either the

init${ORACLE_SID}.ora or spfile${

ORACLE_SID}.ora in

$ORACLE_{HOME|BASE}/admin/DBNAME/pfile and makes a symbolic

link to

$ORACLE_HOME/dbs. However, to put a database created with

means other than DBCA under MxDB-Oracle-HiAv control, a copy or

symbolic link of the appropriate configuration file must exist in

$ORACLE_HOME/dbs.

•

ORACLE_{HOME|BASE}/oradata. Before using MxDB-Oracle-HiAv, you

will need to change the oradata directory to a symbolic link that points

to a directory on a PSFS filesystem mounted with the

DBOPTIMIZE

option.

MxDB-Oracle-HiAv contains functionality to build and configure a

demonstration database for training and testing purposes. The database,

called

PILOT, adheres to OFA methodology. MxDB-Oracle-HiAv creates

this database through DBCA without intervention from the operator. All

PILOT database files are located in $ORACLE_HOME/oradata.

The Linux Oracle user must be added to the pmxs group in the /etc/group

file on each server in the Oracle cluster. When you are logged in as user

oracle, the output from the id command then shows pmxs in the list of

groups, for example:

$ id

uid=777(oracle) gid=777(dba) groups=777(dba),11(pmxs)

3. Install MxODM

MxODM is a specialized implementation of the Oracle Disk Manager

library interface. MxODM is installed into the shared Oracle Home

through only one node in the matrix. However, any node in the matrix

can configure and execute the software.
