What is lpar and wpar

Enter lswpar again to verify that the WPAR no longer exists. The managed systems might all be LPARs on a single physical server, or they might be located on multiple physical servers.

You can also perform all the basic WPAR life cycle operations—including create, view and manage properties, start, stop, and delete. A later article will present a more detailed description of how it works and how to use it.

First, you install and configure the management server software on an AIX system in your environment. The agent must then be configured to share WPAR data with a specific management server. After the WPAR Manager and agent components have been configured and started, the WPAR Manager automatically discovers all the managed systems, and begins to record data transmitted by the agents in an internal database.

This view provides information about the characteristics of each managed system, including its current operational state and connectivity with the WPAR Manager. From this view, you are able to drill down to see all the WPARs defined on any of your managed systems.

You can also create and delete WPARs and perform any other life cycle tasks. Another main resource view shows all defined WPARs in your management environment. The WPARs in the list can be in one of several states:. There are also panels for viewing the status of tasks that you have initiated and for monitoring the performance of WPARs over time. Being a hardware-based function, partition mobility is only supported on POWER6 hardware; application mobility is supported on any hardware that supports AIX 6.

Although it is possible to use AIX commands to checkpoint a WPAR, copy critical files to another system, and then restart the WPAR on the target system, it is not easy, and the relocation might fail due to user error. Log files and task status displays in the graphical user interface let you know if a task failed and provide stderr output to help understand what went wrong. The detailed mechanics of how the policy engine works are beyond the scope of this article, but will be covered in a later article.

You can access help for individual pages by clicking the question mark icon at the upper right of any active WPAR Manager page. The page help provides detailed information on how to interact with the page being viewed. In this article, you learned the following basics of workload partitions in AIX 6. Which is best for you depends on your requirements for workload isolation, mobility, and how complete an operating environment you need. Social Profiles.

Maybe however snapmanager does more than just the DB layer, I am not sure. Register or Login. Welcome back! Furthermore, you need to install patches and technology upgrades to each LPAR. While logical partitioning helps you consolidate and virtualize hardware within a single box, operating system virtualization through WPAR technology goes one step further and allows for an even more granular approach of resource management.

Rather than a replacement for LPARs, WPARs are a complement to them and allow one to further virtualize application workloads through operating system virtualization. WPARs allow for new applications to be deployed much more quickly.
