OBE-00600: internal error code, arguments: -9149, backup dest is not allowed to set when log_only policy exists

  • OceanBase Database error code: 9149

  • SQLSTATE: HY000

  • Error reason: The log_only cleanup policy applies to scenarios where only log archiving is enabled and no data backup is performed. When the log_only cleanup policy exists, data backup paths cannot be configured.

  • Solution: Delete the log_only cleanup policy first, and then configure the data backup path.

Note

For V4.4.x versions, this error code was introduced starting from V4.4.1.

OBE-00600: internal error code, arguments: -9150, log_only policy is not allowed to set when backup dest exists

  • OceanBase error code: 9150

  • SQLSTATE: HY000

  • Cause: The log_only cleanup strategy is applicable only to scenarios where log archiving is enabled but no data backup is performed. In scenarios where a data backup path is configured, the cleanup strategy cannot be set to log_only.

  • Solution: If you want to use the log_only cleanup policy, you need to delete the configured data backup path first.

Note

For V4.4.x versions, this error code was introduced starting from V4.4.1.

OBE-00600: internal error code, arguments: -9151, backup clean can not start, because %s

  • OceanBase error code: 9151

  • SQLSTATE: HY000

  • Cause: Data backup and archiving cleanup cannot be performed. Possible reasons include the tenant's status being non-NORMAL (for example, CREATING, RESTORE, etc.) or the tenant not having a cleanup strategy configured (for expiration cleanup scenarios).

  • Solution: Check whether the tenant status is normal. For expiration cleanup scenarios, confirm whether the relevant tenant has a cleanup strategy correctly configured.

Note

For V4.4.x versions, this error code was introduced starting from V4.4.1.

  • OceanBase error code: 9810

  • SQLSTATE: HY000

  • Cause: The dependency information for the materialized view %s is invalid.

  • Solution: Perform a full refresh on the materialized view.

OBE-00600: internal error code, arguments: -11015, Can't update table '%s' while '%s' is being created.

  • OceanBase Database error code: 11015

  • Error reason: The table cannot be updated while it is being created.

  • Solution: Wait until table creation is complete, and then retry.

OBE-00600: internal error code, arguments: -11018, Invalid external file: %s

  • OceanBase Database error code: 11018

  • SQLSTATE: HY000

  • Error reason: The specified external file cannot be read correctly.

  • Solution:

  • Verify that the file exists, the file path is correct, and the current user has access permissions for the file.

  • Check whether the file format or encoding matches.

  • Check whether the file content is corrupted or has format errors.

    OBE-00600: internal error code, arguments: -11020, HDFS: could not open file on hdfs

    • OceanBase Database error code: 11020

    • SQLSTATE: HY000

  • Error reason:

  • The file may not exist, or you may not have permission to access it.

  • The file open mode does not match.

  • Solution:

    • Verify that the file path is correct and that the file actually exists on HDFS.

    • Check HDFS file permissions to ensure that the current user has read or write permissions.

  • Verify that the HDFS NameNode or DataNode services are running properly.

    OBE-00600: internal error code, arguments: -11021, HDFS: error reading the file on hdfs

    • OceanBase Database error code: 11021

    • SQLSTATE: HY000

  • Error reason: Failed to read the HDFS file.

  • Solution:

  • Verify that the HDFS DataNode is running properly and that the network connection is normal.

  • Check the HDFS logs (HDFS-related logs outside OceanBase Database) to determine whether there are corrupt blocks or unavailable replicas.

OBE-00600: internal error code, arguments: -11042, HDFS: malformed uri

  • OceanBase Database error code: 11042

  • SQLSTATE: HY000

  • Error reason:

  • The URI is missing the hdfs:// prefix.

  • The URI is missing the path part. That is, there is no /path after hdfs://authority.

  • Solution:

    • Ensure that the URI format is hdfs://<namenode>:<port>/<path>, including the complete scheme, authority, and path.

    • Check whether the spelling of the LOCATION field in the external table or backup configuration is correct.

OBE-00600: internal error code, arguments: -11043, HDFS: invalid argument

  • OceanBase Database error code: 11043

  • SQLSTATE: HY000

  • Error reason:

  • The HDFS URI format is incorrect.

  • The Kerberos authentication configuration is incorrect.

  • The HDFS client environment is not initialized or is invalid.

    • The HDFS connection parameters are invalid.
    • Failed to set HDFS configuration items.
    • Solution:
    • Check whether the HDFS URI format is correct and whether the HDFS-related configuration is complete.
    • Verify that the files required for Kerberos authentication (keytab, krb5.conf, ticket cache) exist and that the paths are correct.
  • Check the network connectivity of the HDFS cluster and ensure that the NameNode is accessible.

    • Check whether the key=value format of custom HDFS configuration items is correct, and ensure that there are no empty keys or values.

    OBE-00600: internal error code, arguments: -11044, HDFS: not implementation

    • OceanBase Database error code: 11044
    • SQLSTATE: HY000
  • Error reason: An attempt was made to use a feature that HDFS has not implemented. The current HDFS storage backend does not support pwrite and append write operations.

OBE-00600: internal error code, arguments: -11045, HDFS error

  • OceanBase Database error code: 11045

  • SQLSTATE: HY000

  • Error reason:

  • Duplicate access. For example, an already opened file is opened again.

  • Operations such as delete, mkdir, or list are attempted before an HDFS connection is successfully established.

  • File deletion failed, possibly because the file does not exist or permissions are insufficient.

    • Directory creation failed.

    • Write failed.

    • Flush failed.

    • Solution:

    • Check HDFS file or directory permissions and verify that the current user has read, write, and delete permissions.

    • Verify that the target path exists and is correctly formatted.

  • Verify that the lifecycle management of HDFS components is correct to avoid duplicate access or operations before a connection is established.

    • Check whether the HDFS cluster has sufficient disk space.

    OBE-00600: internal error code, arguments: -11046, Invalid path: %.*s

    • OceanBase Database error code: 11046

    • SQLSTATE: HY000

  • Error reason:

  • The column name or path specified in the DDL does not match the spelling or case of the column name in the file. Formats such as Parquet, ORC, and Arrow are usually case-sensitive.

  • The nested structure path is incorrect. For example, addr.city should be accessed, but the DDL specifies addr_city or address.city.

  • Under the same external table, some files are missing the column.

    • Format symbol issue. For example, extra spaces, quotation marks, or escape errors before or after the column name.

    • Solution:

    • Verify that data_access_path on external columns or EXTERNAL_FILE_COLUMN_PATTERN in the DDL statement actually exists in the file schema.

    • For nested types, use the actual hierarchical path separator in the file for exact matching.

  • If the schemas of files in different partitions differ, create separate external tables for the partitions with missing columns, or set a default value for the column to avoid directly mapping a missing column by path.

    • Correct the invalid column definition and recreate the external table.

    OBE-00600: internal error code, arguments: -11047, Column type mismatch between the file and the table: FileColumnType=%s TableColumnType=%s

    • OceanBase Database error code: 11047

    • SQLSTATE: HY000

  • Error reason: The column type in the file does not match the table definition.

  • Solution: Compare the file content with the table definition, identify the mismatched column types, and modify the table definition or file content.

OBE-00600: internal error code, arguments: -11049, Exceed query memory limit (mem_limit=%ld, mem_hold=%ld), please check whether the query_memory_limit_percentage configuration item is reasonable.

  • OceanBase Database error code: 11049

  • SQLSTATE: HY000

  • Error reason: The query memory exceeds the limit.

  • Solution: Check the value of the query_memory_limit_percentage parameter and verify that the setting is reasonable.

OBE-00600: internal error code, arguments: -11063, missing format for external table

  • OceanBase Database error code: 11063

  • SQLSTATE: HY000

  • Error reason: When an external table is created, no file format is specified, or no valid format configuration appears in the DDL statement.

  • Solution:

  • Add a FORMAT clause to the CREATE EXTERNAL TABLE statement and specify a TYPE that matches the actual files.

  • Verify that the TYPE matches the actual file extension and content. For example, if the directory contains .parquet files, use PARQUET instead of CSV.

  • If you use CSV, add delimiter, encoding, and other parameters as needed to avoid successful table creation but abnormal query parsing.

    OBE-00600: internal error code, arguments: -11064, missing access path for external table

    • OceanBase Database error code: 11064

    • SQLSTATE: HY000

  • Error reason: When an external table is created, no data access path is specified. This usually means that LOCATION is not configured, is empty, or is not correctly bound to a Location object.

  • Solution:

  • Add LOCATION to the DDL statement to point to the directory or URL where the external data is stored.

  • Verify that the path is accessible to the OceanBase cluster (network, authentication, mount, object storage AK/SK, and other environment-specific settings).

  • If a Location object is used, verify that the object has been created and that the current user has read permissions before referencing it in the external table.

    • Use a protocol prefix agreed upon with relevant personnel, such as file://, oss://, or hdfs://, depending on the version support.

    OBE-00600: internal error code, arguments: -11081, skip_header and parse_header cannot be used at the same time

    • OceanBase error code: 11081

    • SQLSTATE: HY000

  • Cause: PARSE_HEADER and SKIP_HEADER cannot be used simultaneously because they conflict in meaning.

  • Solution: Do not use the PARSE_HEADER and SKIP_HEADER parameters together when specifying properties related to the external file format.

OBE-00600: internal error code, arguments: -11082, DDL operations on the internal catalog are not allowed

  • OceanBase error code: 11082

  • SQLSTATE: HY000

  • Cause: DDL operations are not allowed on the Internal Catalog.

  • Solution: Check the type of the catalog to be operated on.

OBE-00600: internal error code, arguments: -11083, Command denied to user '%.*s'@'%.*s' for catalog '%.*s'

  • OceanBase error code: 11083

  • SQLSTATE: HY000

  • Cause: The user does not have the permission to operate on the catalog.

  • Solution: Check whether the user has the permission on the catalog and grant the corresponding operation permission to the user.

OBE-00600: internal error code, arguments: -11084, Privilege not allowed for catalogs

  • OceanBase error code: 11084

  • SQLSTATE: HY000

  • Cause: The catalog does not have the required privilege.

  • Solution: Check the privileges of the catalog.

OBE-00600: internal error code, arguments: -11085, CCL rule '%.*s' already exists

  • OceanBase error code: 11085

  • SQLSTATE: HY000

  • Cause: A CCL rule with the same name already exists when creating a new one.

  • Solution: Use the IF NOT EXISTS keyword or delete the old rule before creating a new one.

OBE-00600: internal error code, arguments: -11086, CCL rule '%.*s' doesn't exist

  • OceanBase error code: 11086

  • SQLSTATE: HY000

  • Cause: The CCL rule does not exist when you modify or delete it.

  • Solution: Use the IF EXISTS keyword or verify that the rule name is correct.

OBE-00600: internal error code, arguments: -11087, SQL reach max ccl rule %s, concurrent num %ld

  • OceanBase error code: 11087

  • SQLSTATE: HY000

  • Cause: The SQL concurrency has reached the upper limit of the CCL rule.

  • Solution: Retry after the concurrency decreases, or increase the value of MAX_CONCURRENCY.

OBE-00600: internal error code, arguments: -11088, reject limit %ld reached

  • OceanBase error code: 11088

  • SQLSTATE: HY000

  • Cause: The rejection limit %ld has been reached.

  • Solution: Check the diagnostic error limit information.

OBE-00600: internal error code, arguments: -11089, Location is still in use

  • OceanBase Database error code: 11089

  • SQLSTATE: HY000

  • Error reason: The Location object being accessed is still in use by external tables.

  • Solution: Check all external tables that depend on the Location object, verify that the dependencies have been removed, and then retry the operation.

OBE-00600: internal error code, arguments: -11090, Location access denied

  • OceanBase Database error code: 11090

  • SQLSTATE: HY000

  • Error reason: The specified Location object cannot be accessed.

  • Solution: Check the user's access permissions for the Location object, and grant the user READ permissions by using the GRANT READ ON LOCATION location_name TO user_name WITH GRANT OPTION; command.

OBE-00600: internal error code, arguments: -11091, Can't create location '%.*s'; location exists

  • OceanBase Database error code: 11091

  • SQLSTATE: HY000

  • Error reason: The specified Location object already exists and cannot be created.

  • Solution: Check whether the specified Location object already exists. Add the OR REPLACE keyword to replace the existing Location object definition with a new one, or create a new Location object.

OBE-00600: internal error code, arguments: -11092, location '%.*s' doesn't exist

  • OceanBase Database error code: 11092

  • SQLSTATE: HY000

  • Error reason: The specified Location object does not exist.

  • Solution: Check whether the specified Location object exists, and specify the correct Location object.

OBE-00600: internal error code, arguments: -11093, OBLogService rpc execute failed

  • OceanBase error code: 11093

  • SQLSTATE: HY000

  • Cause: The RPC execution of the log service failed due to insufficient resources or network failure at the target node.

  • Solution: First, locate the target node logs by using the trace_id, and resolve the issue by combining resource monitoring and parameter adjustment.

Note

  • Solution: Check whether the entered sensitive rule name is correct, and enter the correct sensitive rule name.

OBE-00600: internal error code, arguments: -11096, Sensitive column %.*s(%.*s) exists

  • OceanBase Database error code: 11096

  • SQLSTATE: HY000

  • Error reason: The column with the specified name is already a sensitive column. This usually occurs when a DDL statement adds or modifies a sensitive rule and attempts to apply a sensitive rule to a column already covered by another sensitive rule.

  • Solution: Check whether the specified column is a sensitive column, and choose an appropriate column to add the sensitive rule.

OBE-00600: internal error code, arguments: -11097, Sensitive column %.*s(%.*s) does not exist

  • OceanBase error code: 11097

  • SQLSTATE: HY000

  • Error cause: The sensitive column with the specified name does not exist. This usually occurs when a DDL statement modifies a sensitive rule and attempts to remove a column that is not a sensitive column.

  • Solution: Check whether the specified sensitive column exists, and enter the correct sensitive column name.

OBE-00600: internal error code, arguments: -11098, %.*s command denied to user '%.*s'@'%.*s' for sensitive rule '%.*s'

  • OceanBase error code: 11098
