Unexpected workload changes
During a disaster recovery situation, workload that was spread evenly across two LPARS may suddenly be transferred to just one of them.
If an entire LPAR fails, all the applications will be transferred to the other, If the WLM configuration is mainly controlled by shares, the resources should continue to be allocated as before. However, if only one application transfers from one LPAR, it is important to reconfigure the other LPAR for the increased workload. Otherwise, WLM may allocate a large enough share of the resources for the doubled workload.
This implies that each application needs different a workload management configuration when running in a single LPAR.
