zIIP support by the Event Replicator for Adabas, is a feature that enables the Event Replicator Server on z/OS to offload part of its workload from the mainframe’s general processors (GP) to System z Integrated Information Processors (zIIP).
Offloading work from the general processors will free up some of their capacity. This helps decrease the total cost of operation (TCO) of the GPs and makes room for running additional workload on them.
To be able to support zIIPs, the Event Replicator Server must run with an Adabas version that provides zIIP support. For this version of Event Replicator for Adabas, use either Adabas version 8.5 SP1, Adabas for zIIP version 8.4 SP3 or Adabas for zIIP version 8.3 SP5.
Adabas source databases that send replication data to the Event Replicator Server may - but need not - support zIIPs, too. This is independent of whether the Event Replicator Server supports zIIPs. To run an Adabas source database with zIIP support, use either Adabas version 8.5 SP1, Adabas for zIIP version 8.4 SP3 or Adabas for zIIP version 8.3 SP5.
With Event Replicator for Adabas 3.8 SP1, use one of the following combinations of Adabas and the Event Replicator in the Adabas source databases and the Event Replicator Server:
| Source Adabas Nucleus | Event Replicator Server |
|---|---|
|
Adabas 8.5 SP1, Adabas for zIIP 8.4 SP3, Adabas 8.4 SP2, Adabas for zIIP 8.3 SP5, or Adabas 8.3 SP4 and Event Replicator for Adabas 3.8 SP1 or 3.7 SP1 or 3.6 SP1 |
Adabas 8.5 SP1 and Event Replicator for Adabas 3.8 SP1 or 3.7 SP1 |
|
Adabas for zIIP 8.4 SP3, Adabas 8.4 SP2, Adabas for zIIP 8.3 SP5, or Adabas 8.3 SP4 and Event Replicator for Adabas 3.8 SP1 or 3.7 SP1 or 3.6 SP1 |
Adabas for zIIP 8.4 SP3 and Event Replicator for Adabas 3.8 SP1 or 3.7 SP1 |
|
Adabas for zIIP 8.3 SP5 or Adabas 8.3 SP4 and Event Replicator for Adabas 3.8 SP1 or 3.7 SP1 or 3.6 SP1 |
Adabas for zIIP 8.3 SP5 and Event Replicator for Adabas 3.8 SP1 or 3.7 SP1 |
Prerequisites and additional information to enable zIIP support in the Event Replicator for Adabas are described in a new separate section Special Considerations for zIIP Support under Event Replicator Installation Steps for z/OS Systems in the Installation documentation.
