Installation topologies for Universal Cache
You can install the Universal Cache components on the same server for a simple evaluation topology, or on independent servers for a production-level topology.
General principles
There can be several solidDB® cache databases in the Universal Cache deployment, but only one backend data server.
Typically, the IBM Infosphere CDC instance is created on each node participating in IBM Infosphere CDC replication.
The solidDB® server and the IBM Infosphere CDC for solidDB® instance do not need to be located on the same node.
This is because IBM Infosphere CDC for solidDB® can read and insert data into a solidDB® database using both local and remote JDBC connection.
In configurations using solidDB® High Availability (HotStandby), the IBM Infosphere CDC instance must run on a different node than the solidDB® server.
