Maintain HCL OneDB availability

You can ensure that your applications can always access HCL OneDB™ even if a single server fails by configuring a high-availability solution.

Sometimes HCL OneDB-embedded applications are deployed to environments where a DBA might not be immediately available. You can configure these applications to switch to another server if the original database server has a problem or is down for maintenance.

You can choose between different high-availability configurations depending on your needs:

  • A high-availability cluster consists of a primary server and one or more secondary servers that are copies of the primary server. Secondary servers can be shared-disk, local, or remote. You can configure automatic connectivity based on available servers.
  • Enterprise Replication allows a great deal of flexibility in how the participating servers are organized and whether all or a subset of the data is replicated.
