same workload partition. The systems administrator accesses the workload partition via
the administrator console or via regular network tools such as telnet or ssh. The system
workload partition is removed only when requested.
Application workload partitions - these are light weight workload partitions because there
is no system services involved, there is no file system isolation since it uses the global
environment system file system, Telnet is not supported but access through console login
is available. Once the application process or processes are finished the workload partition
is stopped.
For a detailed list of the workload partitions concepts and function, refer to Introduction to
Workload Partition Management in IBM AIX Version 6, SG24-7431.
3.3.6 PowerVM AIX 6 Workload Partition Manager
IBM PowerVM AIX 6 Workload Partition Manager (WPAR Manager) is a platform
management solution that provides a centralized point of control for managing workload
partitions (WPARs) across a collection of managed systems running AIX. It is an optional
product designed to facilitate the management of WPARs as well as provide advanced
features such as policy based application mobility for automation of workload partitions
relocation based on current performance state.
The workload partition manager is an intuitive graphical user interface based tool designed to
provide a centralized interface for administration of WPAR instances across multiple systems.
By deploying the workload partitions manager, users are able to take full advantage of
workload partitions technology by leveraging the following features:
Basic life cycle management
Create, start, stop, and delete WPAR instances
Manual WPAR mobility
User initiated relocation of WPAR instances
Creation and administration of mobility policies
User defined policies governing automated relocation of WPAR instances based on
performance state
Creation of compatibility criteria on a per WPAR basis
User defined criteria based on compatibility test results gathered by the WPAR Manager
Administration of migration domains
Creation and management of server groups associated to specific WPAR instances which
establish which servers would be appropriate as relocation targets
Server profile ranking
User defined rankings of servers for WPAR relocation based on performance state
Reports based on historical performance
Performance metrics gathered by WPAR Manager for both servers and WPAR instances
Event logs and error reporting
Detailed information related to actions taken during WPAR relocation events and other
system operations
