Systems management

 

Make the most of your system resources by using this information to provide optimum system function, efficiency, and availability. Learn how to distribute and group system resources, plan backup and recovery situations, secure your system, manage multiple systems, and analyze or troubleshoot any performance problems that might occur on your system.

Availability
Availability is the measure of how often your data and applications are ready for access when you need them. In today's fast-paced Internet economy, availability is a critical aspect of your computing environment. This category contains information about how to decide what level of availability you need and the technologies and techniques you can use to achieve your availability goals.

Backup and recovery
This category contains information on how to plan a backup and recovery strategy and how to back up your system. It also includes information about the Backup, Recovery, and Media Services plug-in to iSeries Navigator, information about recovering your system, and answers to some frequently asked questions about backup and recovery.

Basic system operations
The System i platform is a versatile, powerful, and easy-to-use system. However, many of the functions and features of this environment are specific to IBM and the i5/OS operating system, and might not be familiar to people who are more familiar with a Windows or UNIX operating system.

Capacity on Demand
Capacity on Demand (CoD) enables you to dynamically activate one or more resources on your system as your business peaks dictate. You can activate inactive processors or memory units that are already installed on your system on a temporary and permanent basis.

Clusters
Clusters let you efficiently group your System i products together to set up an environment that provides availability that approaches 100 percent for your critical applications, devices, and data.

Common Information Model (CIM)
The Common Information Model (CIM) is a standard developed by a consortium of major hardware and software vendors (including IBM) called the Distributed Management Task Force (DMTF) as part of the Web Based Enterprise Management (WBEM) initiative.

Disk management
Use the information in this topic to effectively manage your disk units, disk pools, independent disk pools and find strategies to help you protect the data on your disk units.

Journal management
Journal management provides a means by which you can record the activity of objects on your system. When you use journal management, you create an object called a journal. The journal records the activities of the objects you specify in the form of journal entries. The journal writes the journal entries in another object called a journal receiver.

Logical partitions
Logical partitions enables you to distribute resources within a single system to make it function as if it were two or more independent systems. Plan your next upgrade to include logical partitions.

Management Central
As a part of iSeries Navigator, Management Central provides the technology that you need to do systems management tasks across one or more systems simultaneously.

Performance
How much do you invest in managing the performance of your system? The needs of your business change, sometimes sooner than you expect.

Security
These topics help you secure your server. You can find information about securing applications, communications, and your system.

System values
System values are pieces of information that affect the system operating environment. System values are not objects on the system. Rather, system values contain control information for the operation of certain parts of the system.

Time management
Within the time management component of iSeries Navigator, you can work with the time zone and time adjustment functions. With these functions, you can choose a time zone for your system to use and adjust the system time.

Work management
Work management is an important building block within the i5/OS operating system.
