Querying and Downloading Binlogs (OBT)

+

Binlogs record all DDL and DML statements (except data query statements). You can download binlogs to a local PC for further analysis.

+

This section describes how to enable binlog, and then query and download binlogs on the TaurusDB console.

+

Billing

Binlogs are stored in OBS buckets.

+
+

Prerequisites

  • Binlog can only be enabled when the following conditions are met:
    • If the kernel version of your DB instance is earlier than 2.0.45.230900, the value of log-bin must be ON. To view and modify the parameter value, see Modifying a Parameter Template.
    • If the kernel version of your DB instance is 2.0.45.230900 or later, the value of rds_global_sql_log_bin must be ON.
    +
  • Before viewing and downloading binlogs, you need to enable binlog by referring to Enabling Binlog.
+
+

Constraints

To use binlogs, set the log-bin or rds_global_sql_log_bin parameter to ON.

    Upgrading the Minor Version of a DB Instance

    -

    Scenarios

    You can manually upgrade minor versions of your instances to improve performance, add new functions, and fix bugs.

    +

    Scenarios

    You can upgrade the minor version of your DB instance to improve performance, optimize functions, and fix bugs.

    -

    Precautions

    • The upgrade will cause the instance to reboot and interrupt services intermittently. To limit the impact of the upgrade, perform the upgrade during off-peak hours, or ensure that your applications support automatic reconnection.
    • If an instance contains a large number of table partitions (more than 1 million), it may take more than 2 hours to reboot the instance.
    • If the primary node and read replicas of an instance are deployed in the same AZ, a minor version upgrade will trigger a failover. If they are in different AZs, a minor version upgrade will trigger two failovers. A failover means that the system fails over to a read replica in case the primary node is unavailable.
    • When you upgrade a minor version of an instance, minor versions of read replicas (if any) will also be upgraded automatically. Minor versions of read replicas cannot be upgraded separately. A minor version upgrade cannot be rolled back after the upgrade is complete.
    • DDL operations, such as CREATE EVENT, DROP EVENT, and ALTER EVENT, are not allowed during a minor version upgrade.

    Table 1 Upgrade scenarios

    Upgrade Information

    +

    Upgrade Scenario

    +

    Description

    +

    Kernel version

    +

    There are three scenarios for upgrading a minor version based on different kernel versions:

    +
    • Scenario 1: If the instance's kernel version is below 2.0.51.240305, it will be upgraded to 2.0.51.240305 first, followed by a minor version pre-upgrade and then a minor version upgrade.
    • Scenario 2: If the instance's kernel version is 2.0.51.240305, it will undergo a minor version pre-upgrade first. After that, you need to click Upgrade again to start a minor version upgrade. The following operations use this upgrade method as an example.
    • Scenario 3: If the instance's kernel version is above 2.0.51.240305, clicking Upgrade will directly trigger a minor version upgrade.
    +
    • If the kernel version is 2.0.51.240305 or earlier, the upgrade involves changes to the underlying data dictionary and may take a long time.
    • For scenario 2, binlog needs to be enabled before the upgrade. Ensure that the value of rds_global_sql_log_bin is ON, the value of binlog_expire_logs_seconds is at least 86400, and the value of default_collation_for_utf8mb4 is utf8mb4_0900_ai_ci.
    +

    Upgrade time

    +

    There are two ways to upgrade a minor version based on different upgrade times.

    +
    • Upon submission: The system upgrades the minor version immediately after your manual submission of the upgrade request on the Basic Information page of the instance.
    • In maintenance window: The system upgrades the minor version during the maintenance window you have specified.
    +

    If the kernel version of your instance has potential risks or major defects, has expired, or has been brought offline, the system will notify you by SMS message or email and deliver an upgrade task during the maintenance window.

    +
    -

    Procedure

    1. Log in to the management console.
    2. Click in the upper left corner and select a region and a project.
    3. Click Service List. Under Databases, click TaurusDB.
    4. On the Instances page, click the target instance to go to the Basic Information page.
    5. In the DB Instance Information area, click Upgrade in the DB Engine Version field.
    6. In the displayed dialog box, select a scheduled time and click OK.

      Upon submission: The system upgrades the minor version immediately after your submission of the upgrade request. After the operation is complete, in the Task Center page, click Instant Tasks and view the information about the upgrade task.

    Phase

    +

    Constraint

    +

    Before the upgrade

    +
    • To upgrade the kernel version from 2.0.51.240305 to 2.0.54.240600 or later, ensure that the value of rds_global_sql_log_bin is ON and the value of binlog_expire_logs_seconds is at least 86400. For details about how to set these parameters, see Modifying a Parameter Template.
    • If the rds_global_sql_log_bin parameter was recently set to ON, you need to connect to the database and run the following command to check whether binlog is enabled for all threads.
      select @@session.rds_sql_log_bin_inconsistent_count;
      +
    +

    During the upgrade

    +
    • Scenario 1 or 3: If the primary node and read replicas of an instance are deployed in the same AZ, a minor version upgrade will trigger a failover. If they are in different AZs, a minor version upgrade will trigger two failovers. A failover means that the system fails over to a read replica in case the primary node is unavailable.
    • Scenario 1 or 3: The upgrade will cause the instance to reboot and briefly interrupt workloads for about 30 to 90 seconds. To minimize the impact of the upgrade, perform the upgrade during off-peak hours, or ensure that your applications support automatic reconnection.
    • Scenario 2: During the minor version pre-upgrade, the instance will not reboot, which means workloads will not be affected.
    • Scenario 2: The minor version upgrade will cause the instance to reboot, so workloads will be interrupted. The upgrade takes 15 to 20 minutes, and workloads are intermittently interrupted for 1 to 2 minutes. To minimize the impact, perform the upgrade during off-peak hours.
    • If an instance contains a large number of table partitions (more than 1 million), it may take more than 2 hours to reboot the instance.
    • When you upgrade the minor version of an instance, minor versions of read replicas (if any) will also be upgraded. During the upgrade, the read replicas will reboot. To minimize the impact, perform the upgrade during off-peak hours. Minor versions of read replicas cannot be upgraded separately. Once you upgrade the minor version, the instance will be upgraded to the latest minor version. A minor version upgrade cannot be rolled back after the upgrade is complete.
    • DDL operations on events, such as CREATE EVENT, DROP EVENT, and ALTER EVENT, are not allowed during a minor version upgrade.
    • If the message "Upgrade failed. Reduce the service load of the instance and click Retry" is displayed on the console, the upgrade fails due to heavy service load. Reduce the service load or retry the upgrade during off-peak hours.
    +

    After the upgrade

    +
    • Scenario 2: If the upgrade fails, the instance will be rolled back to a previous version and its data will be restored to a new instance named original_instance_name_copy. The original instance will become unavailable after the rollback, and the new instance will start to incur charges once the original instance is deleted.
    • Data cannot be restored to a point in time when a data dictionary upgrade was in progress. By default, the system searches for the most recent available point in time instead.
    • During the period between a data dictionary upgrade and the next full backup, data of the instance cannot be restored to the original instance or an existing instance.
    • When restoring backups, ensure that the data dictionary version of the target instance is the same as that of the source instance.

If the upgrade has not been started, check whether the value of rds_global_sql_log_bin is ON and the value of binlog_expire_logs_seconds is at least 86400. If the parameters are not correctly configured, the upgrade cannot be performed.
      • If the parameters are correctly configured but the upgrade has not started, it could be due to that the value of rds_sql_log_bin_inconsistent_count is not 0. Wait until this value becomes 0 before proceeding with the upgrade.
