Moving a running Workload Partition to another machine or LPAR1. Installing new machine

• Moving a WPAR very fast way to take on work2. Multi-system workload balancing

• IT optimization to maximize CPU, memory, I/O effectiveness3. Empty a machine for application outage avoidance

• Green computing, Upgrade machine (AIX or firmware) or for Repair

Two Workload Partitions Types

Create

Stop

Run

RemoveDefined Active

Application Workloads– Isolate an individual application

– Light-weight, one process

• Can start further processes

– Created & started in seconds

– Starts when created

– Automatically removedwhen application stops

– Shares global file system

– Good for HPC

• Long running applications

Create and run

Stop and remove

System Workloads– Complete virtualized OS environment

• Runs multiple services & applications

– Needs to be created as it builds its filesystems

– Removed only when requested

– Like another AIX system

• Own root user, users, and groups

• Own services like inetd, cron, syslog

• Can be stopped and restarted

– Does not share writable file systems with other workload partitions or the global system

– Integrated with RBAC - granular security controls

Workload Application Mobility = Relocate

For Application Mobility– On WPAR Manager select WPAR, click Relocate, select target AIX = Done

Underlying commands are– Checkpoint WPAR : chkptwpar –k

• Freeze WPAR, save the WPAR processes & state to a statefile on NFS• Kill the WPAR processes once they are no longer needed

– Restart WPAR : restartwpar

• Take the statefile, rebuild the WPAR processes & state and start the WPAR
