Before you set up the high availability environment, verify that your system meets the following prerequisites:
It is recommended that the
Data Integration Hub
repository is on a high availability database, such as Oracle Real Application Clusters.
The
Data Integration Hub
repository and the document store are on high availability storage systems, such as Network-Attached Storage (NAS).
The high availability environment includes a clustered file system, such as Global File System (GFS) or Veritas Cluster File System) (VxCFS).
The document store is on a shared file system that is accessible from all of the cluster components using the same directory path.
The cluster consists of multiple active
Data Integration Hub
server nodes.
The PowerCenter real-time workflows are active and running.
A load balancer is installed, such as the F5 Load Traffic Manager or the Apache HTTP Server.
The clocks on all
Data Integration Hub
nodes are synchronized to within 30 seconds of each other. Use the Network Time Protocol (NTP) to synchronize the clocks.
The ping latency between the nodes in the cluster is 10 ms or smaller.
All nodes in the cluster use the same operating system platform. Clusters with nodes that use both UNIX and Microsoft Windows operating systems are not supported.
