Creating Oracle Directories

For Oracle 10g you only need to create the directory for $ORACLE_BASE:

su - root

mkdir -p /u01/app/oracle

chown oracle.oinstall /u01/app/oracle

If you want to comply with Oracle's Optimal Flexible Architecture (OFA), then you do not want to place

the database files in the /u01 directory but in another directory, file system or disk such as /u02:

su - root

mkdir -p /u02/oradata/orcl

chown oracle.oinstall /u02/oradata/orcl

In this example, "orcl" stands for the name of the database which will also be the name of the

instance. This is typically the case for single instance databases.

24.1. Optimal Flexible Architecture (OFA) for 10g R1

(10.1.0.2)

The OFA standard is a guideline created by Oracle to ensure reliable Oracle installations. For Oracle

10g Database, the OFA recommended Oracle home path has changed.

The home path for the first 10g (10.1.0) database installation on a system would be:

/u01/app/oracle/product/10.1.0/db_1

If you would install a second Oracle 10g Database 10g (10.1.0) on the same system, the Oracle home

directory should be as follows:

/u01/app/oracle/product/10.1.0/db_2

If the Oracle 10g software is not owned by the user oracle but by the user "oraowner", then the

path of the Oracle home directory would be:

/u01/app/oraowner/product/10.1.0/db_1

/u01/app/oraowner/product/10.1.0/db_2

The standard directory name for Oracle 10g is "app":

/u01/app/oracle/product/10.1.0/db_1

Oracle recommends to use mount points such as /u01, /u02, and so on, complies with the OFA

guidelines. But others can be used, for example:

/disk_1/app/oracle/product/10.1.0/db_1

The subtree for database files not stored in ASM disk groups should be named as follows:

/u02/oradata/<db_name_1>

/u02/oradata/<db_name_2>

1 2 ... 90 91 92 93 94 95 96 97 98 99 100 ... 159 160
