Initial status

The initial status in ongoing operation is the basis for these considerations. For this purpose the most important application cases, such as OLTP mode or critical batch applications, must be monitored on the original server using openSM2. The results are then evaluated and which server will be most suitable as a target server is forecast.

The following must always be observed in the case of server migration:

• Current CPU workload of the original server (high / low)
  In OLTP mode the server’s CPUs should have a workload of less than 70%.In batch mode a CPU workload of up to 100% is generally maintainable.

• Planning the main memory requirement when changing the BS2000 versionThe extra capacity required depends on the version. On average 1 - 2% per version must be estimated.

• Taking into account the system’s own growth requirements
  Example: 5% per year for 3 years, i.e. around 15% growth requirements.

• Influence of adding new applications or relocating existing ones
  If applications are omitted from the new server or new ones are added, this must be taken into account.

If required, it is recommended that the offering of the BS2000 Optimization Service and the BS2000 demo center should be used:

• Performance consulting when migrating

• Test measurements for customer applications on the target hardware
