Windows, AIX, Linux Installation and configuration roles During your planning, identify the administrators in your environment who can provide connection information, configuration assistance, and access rights for the installation. These roles represent areas of responsibility for the environment. These administrators can supply the parameters for your configuration checklist and assist with the installation, configuration, and maintenance of your system.
Configuration cannot be copied over directly, although most GRUB Legacy users should not find the syntax too surprising. This makes it easier to handle versioned kernel upgrades.
The configuration file is now written in something closer to a full scripting language: This is not available in all configurations see Environment block. GRUB 2 has more reliable ways to find its own files and those of target kernels on multiple-disk systems, and has commands see search to find devices using file system labels or Universally Unique Identifiers UUIDs.
A graphical terminal and a graphical menu system are available. GRUB 2 puts many facilities in dynamically loaded modules, allowing the core image to be smaller, and allowing the core image to be built in more flexible ways.
Role of a boot loaderPrevious: Basic functions must be straightforward for end-users. Rich functionality to support kernel experts and designers. Except for specific compatibility modes chain-loading and the Linux piggyback formatall kernels will be started in much the same state as in the Multiboot Specification.
Only kernels loaded at 1 megabyte or above are presently supported. Any attempt to load below that boundary will simply result in immediate failure and an error message reporting the problem.
Recognize multiple executable formats Support many of the a. Symbol tables are also loaded.
Chain-loading of other boot loaders is also supported. Load multiples modules Fully support the Multiboot feature of loading multiple modules.
Load a configuration file Support a human-readable text configuration file with preset boot commands. You can also load another configuration file dynamically and embed a preset configuration file in a GRUB image file. The list of commands see Commands are a superset of those supported on the command-line.
An example configuration file is provided in Configuration. Provide a menu interface A menu interface listing preset boot commands, with a programmable timeout, is available.
There is no fixed limit on the number of boot entries, and the current implementation has space for several hundred. Have a flexible command-line interface A fairly flexible command-line interface, accessible from the menu, is available to edit any preset commands, or write a new boot command set from scratch.
If no configuration file is present, GRUB drops to the command-line. The list of commands see Commands are a subset of those supported for configuration files. Editing commands closely resembles the Bash command-line see Command Line Editing in Bash Featureswith TAB-completion of commands, devices, partitions, and files in a directory depending on context.
Support multiple filesystem types Support multiple filesystem types transparently, plus a useful explicit blocklist notation.Steps to implement Role based security Implementation steps.
This section describes the practical steps on how to implement Role based security based on the example mentioned in the previous section. Although you cannot use the add Roles and Features Wizard to install roles, role services, and features on more than one target server in a single wizard session, you can use a Windows PowerShell script to install roles, role services, and features on multiple target servers that you are managing by using Server Manager.
After you install Oracle Database, you should secure the database installation and configuration. Oracle provides commonly used ways to do secure the database installation and configuration, all of which involve restricting permissions to specific areas of the database files.
