Installation Prerequisites

The following are installation prerequisites for installing WebFOCUS Narrative Charts on Linux:

10GB of available disk space.
8GB of RAM or higher is recommended.
If the temp directory on the host does not meet the minimum size requirements, the InstallAnywhere environment variable IATEMPDIR can be set to use an alternate directory.
You may specify an alternate /tmp location by setting the following environment variable:
```
IATEMPDIR=/large_tmp
export IATEMPDIR
```

System Resource Limits

The operating system provides ways of limiting the amount of resources that can be used. These limits can affect the installation process.

Use the ulimit command to set process memory-related resource limits for your session.

The WebFOCUS Narrative Charts installation program requires ulimit to be set to 8192.

Limits can be hard or soft. Hard limits are set by the root user. Only the root user can increase hard limits, although other users can decrease them. Soft limits can be set and changed by other users, but they cannot exceed the hard limits. To view the current limits, enter the following command:

ulimit -a

Use the /etc/security/limits.conf file to store ulimit settings. Changes to this file should be made by a system administrator.
