These error codes indicate fatal errors. If a client receives an 8xxx error, the client must close the current SQL connection.

ERROR 8001 (08004): Server is initializing

• Error code in OceanBase Database: 8001

• Cause: The OBServer node receives a remote procedure call (RPC) during startup.

• Solution: Wait until the OBServer node is started.

ERROR 8002 (08004): Server is stopping

• Error code in OceanBase Database: 8002

• Cause: The OBServer node received an RPC while it was stopping.

• Solution: Wait until the OBServer node is stopped. Alternatively, run the kill -9 command to forcibly terminate the observer process.

ERROR 8003 (08004): Packet checksum error

• Error code in OceanBase Database: 8003

• Cause: The checksum verification for the RPC packet received by the OBServer node failed. This is usually caused by version incompatibility.

• Solution: Contact OceanBase Technical Support for troubleshooting.

ERROR 8004 (08004): Packet cluster_id not match

• Error code in OceanBase Database: 8004

• Cause: The cluster_id value in the RPC packet received by the OBServer node is not as expected. This is usually because an OBServer node node in another OceanBase cluster is connected to the current cluster.

• Solution: If an OBServer node in another cluster is unexpectedly connected to the current cluster, stop the cluster as soon as possible. In other cases, contact OceanBase Technical Support for troubleshooting.
