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.
