This new feature provides the ability to resolve or reset a purchase order or requisition that is no longer being processed, but the system still indicates it is ‘in use’. We all remember those situations where we could never figure out how the order got hung up.

What we previously had to do was run a behind the scenes script to reset the flag so the order was again accessible. This enhancement provides the ability to resolve the issue and resume processes quickly.

This option is now on the PUR menu, and the user can select the Purchase Order/Requisition in Use Maintenance, PUR940D. The user then enters an order or requisition to remove the “In Use” status.

• You get more out of your existing resources. Pool common infrastructure resources and break the legacy “one application to one server” model with server consolidation.

• You can reduce datacenter costs by reducing your physical infrastructure and improving your server to admin ratio. Fewer servers and related IT hardware means reduced real estate and reduced power and cooling requirements. With better management tools, you can improve your server to admin ratio so personnel requirements are reduced.

• You can increase the availability of hardware and applications for improved business continuity.

• Securely back up and migrate entire virtual environments with no service interruptions. Eliminate planned downtime and recover immediately from unplanned issues.

• Gain operational flexibility. Respond to market changes with dynamic resource management, faster server provisioning, and improved application deployment.

The disadvantages of virtualization include the following:

• Virtualization adds overhead to the CPU, memory, IO, and network.

• Virtualization adds an additional layer to the hardware and software stack. Therefore, additional complexity is introduced in the following circumstances:

• When sizing the physical server.
• When planning VM capacity.
• When planning multiple VMs on the same physical server.
• When investigating performance issues.
