IBM AIX Question:

The following are some unique system management features of AIX.
☛ Logical Volume Manager :- The Logical Volume Manager (LVM) maintains the hierarchy of logical structures that manage disk storage.
☛ System Resource Controller:- The System Resource Controller (SRC) provides a set of commands and subroutines for creating and controlling subsystems and is designed to minimize the need for human intervention in system processing.
☛ Object Data Manager :- The Object Data Manager (ODM) is a data manager intended for the storage of system data.
☛ Software Vital Product Data:- Certain information about software products and their installable options is maintained in the Software Vital Product Data (SWVPD) database.
☛ Workload management :- Workload Manager (WLM) is designed to provide the system administrator with increased control over how the scheduler virtual memory manager (VMM) and the disk I/O subsystem allocate resources to processes. You can use WLM to prevent different classes of jobs from interfering with each other and to allocate resources based on the requirements of different groups of users.
☛ Operating system updates:- The operating system package is divided into file-sets, where each file-set contains a group of logically related customer deliverable files. Each file-set can be individually installed and updated.
