ERROR 4530 (HY000): Zone info \'%s\' not exist

Error code in OceanBase Database: 4530
Cause: The specified zone does not exist. Generally, this error occurs during a major compaction of a specified zone or a switchover of the primary zone.
Solution: Check whether the specified zone exists. You can query the DBA_OB_ZONES table to obtain the required information.

ERROR 4544 (42000): Root not integrated

Error code in OceanBase Database: 4544
Cause: During a rotating major compaction, the system checks whether the available replicas in each partition constitute the majority of replicas in the current partition. This error occurs if the available replicas in a partition are fewer than the majority of replicas.
Solution: Immediately check why the majority of replicas in the partition are unavailable.

ERROR 4547 (HY000): global merge not started

Error code in OceanBase Database: 4547
Cause: This error occurs in the precheck before a manual rotating major compaction. A manual major compaction is not allowed for a cluster if no major freeze has been initiated for the cluster.
Solution: Check whether a major freeze has been initiated for the cluster.

ERROR 4548 (HY000): merge already started

Error code in OceanBase Database: 4548
Cause: This error occurs in the precheck before a manual rotating major compaction. If a manual major compaction has been initiated for a zone, you cannot initiate another manual major compaction for the cluster.
Solution: Check whether a manual major compaction has been initiated for the zone.

ERROR 4549 (HY000): rootservice already exist

Error code in OceanBase Database: 4549
Cause: This code is returned in the self-check before the current RootService replica starts. If another RootService replica is already running, the current RootService replica does not start.
Solution: Troubleshooting is not required.

ERROR 4550 (HY000): rootservice is shutdown

Error code in OceanBase Database: 4550
Cause: The RootService replica that receives the current request is inactive because no leader is elected or the request is sent to a follower.
Solution: Retry the request. If no leader is elected for RootService replicas, further troubleshooting is required.

ERROR 4551 (HY000): server migrate in denied

Error code in OceanBase Database: 4551
Cause: The OBServer node fails to execute the balance task due to reasons such as a full disk or an excessive number of partitions. As a result, the OBServer node returns a package indicating the balance task execution failure to the RootService and returns this error code.
Solution: The RootService automatically stops scheduling tasks to the OBServer node and then re-schedules tasks to the OBServer node after the specified period elapses. If the OBServer node continuously returns this error code, check whether the disk is overloaded and whether excessive partitions are in use.

ERROR 4552 (HY000): rebalance task can not executing now

Error code in OceanBase Database: 4552
Cause: Before executing a balance task, the RootService checks whether the leader is successfully switched, whether the replica already exists on the destination server, and whether the replica schema exists. If the check results indicate that the balance task cannot be executed, the task execution ends, and this error is returned.
Solution: Check the execution conditions of the balance task and identify the specific cause of the execution failure. For example, if the leader fails to be switched before migration, identify the cause of the leader switchover failure.

ERROR 4554 (HY000): rebalance task not in progress on observer

Error code in OceanBase Database: 4554
Cause: The RootService periodically sends RPC packets to the OBServer node to check whether each balance task exists. If a balance task no longer exists, the RootService marks the end of the balance task and returns this error code.
Solution: This error usually occurs if the response from meta_table is delayed or the response from the balance task to the RootService is lost. Usually, troubleshooting is not required.

ERROR 4605 (HY000): Data source timeout

Error code in OceanBase Database: 4605
Cause: The current RPC timed out during migration and replication at the storage layer.

Solution: Check the cause of the timeout, or extend the timeout period.

ERROR 4622 (HY000): wait all rs online timeout

Error code in OceanBase Database: 4622
Cause:
1. The system checks whether the OBServer node that runs the RootService is in the ALIVE state during bootstrapping. This error occurs if the server is not in the ALIVE state.
2. The system checks whether the OBServer node that runs the RootService is in the in_service state or whether the value of start_service_time is 0 during bootstrapping. This error occurs if the server is not in the in_service state or the value of start_service_time is not 0.
Solution: Check the cause of the timeout, or extend the timeout period.

ERROR 4624 (HY000): zone '%s' server '%s' %s resource is not enough to hold a new unit

Error code in OceanBase Database: 4624
Cause:
1. The system checks whether resources are sufficient during resource allocation in scenarios such as creating or modifying a resource pool, migrating resource units, or supplementing replicas. This error occurs if resources are insufficient.
2. The system checks whether resources are sufficient when you create a table. This error occurs if resources are insufficient.
Solution: Adjust the amount of resources to be allocated based on the specific cause.

ERROR 4626 (HY000): resource pool \'%s\' has already been granted to a tenant

Error code in OceanBase Database: 4626
