What Should I Do If a Scheduled Job Fails and Link Connectivity Is Abnormal?

Symptom

The connection to the source database is abnormal. The following message is displayed:

Check whether the IP address, host name, and port number are correct, and whether the network security group and firewall are correctly configured. Locate the cause based on the error message.

Fault Analysis

Query the cluster information, obtain the public IP address, and curl the IP address of the source database from the CDM cluster.

According to the result, the CDM cluster is faulty. The EIP is not bound to the CDM cluster.

You are advised to unbind and then bind the EIP to the CDM cluster.

Solution

After releasing the EIP, bind another EIP to the CDM cluster or assign a VPC agency to the CDM cluster, and check whether the EIP is normal.
