Installation guide

4. Check the soft limit for the stack setting. Ensure that the result is in the

recommended range. For example:

$ ulimit -Ss

10240

$ ulimit -Hs

32768

5. Repeat this procedure for each Oracle software installation owner.

If necessary, update the resource limits in the

/etc/security/limits.conf

configuration file for the installation owner. However, note that the configuration file

is distribution specific. Contact your system administrator for distribution specific

configuration file information.

7 Creating Required Directories

Create directories with names similar to the following, and specify the correct owner,

group, and permissions for them:

■ The Oracle base directory

■ An optional Oracle data file directory

The Oracle base directory must have 3 GB of free disk space, or 4 GB of free disk space

if you choose not to create a separate Oracle data file directory.

To create the Oracle base directory:

1. Enter the following command to display information about all mounted file

systems:

# df -k

This command displays information about all the file systems mounted on the

system, including:

■ The physical device name

■ The total amount, used amount, and available amount of disk space

■ The mount point directory for that file system

2. From the display, identify either one or two file systems that meet the disk space

requirements mentioned earlier in this section.

Note: If the

grid

oracle

users are logged in, then changes in the

limits.conf file do not take effect until you log these users out and log

them back in. You must do this before you use these accounts for

installation.

Note: If you do not want to create a separate Oracle data file

directory, then you can install the data files in a subdirectory of the

Oracle base directory. However, this is not recommended for

production databases.
