Components Failed to Connect to DBService in Normal State

Symptom

Figure 1 DBService status

Cause Analysis

1. The upper-layer component is DBService connected through dbservice.floatip.
2. Run the netstat -anp | grep 20051 command on the node where DBServer resides. It is found that the Gauss process of DBService is not bound to the floating IP address during startup, and only local IP address 127.0.0.1 is monitored.

Solution

1. Restart the DBService service.
2. Run the netstat -anp | grep 20051 command on the active DBServer node to check whether dbservice.floatip is bound.
