It generally takes less than 10 minutes to create a TencentDB instance. The time it takes to create read-only replicas is subject to the data volume of the source instance. The larger the data volume, the longer the time.
If it takes longer to create an instance, there may be something wrong. Please contact us.
You can log in to the TencentDB for MySQL console and select More > Terminate/Return or Terminate/Return & Refund in the Operation column in the instance list to return an instance. For more information, please see Terminating Instance.
When an instance is returned, it will be retained in the recycle bin for a period of time. A pay-as-you-go instance will be retained for 1 day. During this period, you can go to the recycle bin and restore the instance.
You can view the maximum number of connections to TencentDB for MySQL in the console. If the number of connections gets too high, you are recommended to locate the cause and solve the problem first instead of directly increasing the maximum value.
Log in to the TencentDB for MySQL console, click an instance name to enter the instance management page, select Database Management > Parameter Settings, and modify the
max_connections represents the allowed maximum connections (1-100,000) in instance monitoring. Number of open connections means the number of connections available at the current moment, a value that changes in real time.
The monitoring center oversees the disk capacity of a TencentDB instance. When the disk utilization is over 90%, SMS and email alarms will be triggered. You can configure alarm recipients in Cloud Monitor to receive such alarms. (For more information on how to configure, see Alarm Policies (Cloud Monitor)).
You need to adjust the
lower_case_table_names parameter of the database.
