About Readiness Probes for Replicated Configurations

For active/standby pair replication configurations, the TimesTen Operator provides two different definitions of ready along with two associated readiness probes. They are as follows:

• A TimesTen database is considered ready if it is the active database in an active/standby pair replication scheme. The TimesTen Operator provides the /tmp/active readiness probe for this definition of ready.

• A TimesTen database is considered ready if it is loaded and open for connections. The TimesTen Operator provides the /tmp/readiness readiness probe for this definition of ready.

These two definitions of ready fulfill different and incompatible requirements. You must decide what definition of ready is best for your environment.

You also have the option of defining your own readiness probe. If you do so, the TimesTen Operator uses your readiness probe rather than one of the provided ones.
