Shrinking Database

Last updated: 2022-03-29 15:21:33

    TencentDB for SQL Server supports reducing database size by shrinking all database files to release unused space. This document describes how to shrink a database in the TencentDB for SQL Server console.

    Shrinking One Database

    1. Log in to the TencentDB for SQL Server console. In the instance list, click an instance ID or Manage in the Operation column to access the instance management page.
    2. On the Database Management tab, locate the row of the database to be shrunk and click Other > Shrink Database in the Operation column.
    3. The pop-up window displays the database name and the ratio of remaining space. Currently, only shrinking to 10% of the free space is supported.
      Note:

      Only 10% of the database's free space will remain once it has been shrunk. However, if 10% of free space is less than 2 GB, the free space will be shrunk to 2 GB.


      You can view the task progress of database shrinking through Running Tasks in the top-right corner of the Database Management tab.

    Batch Shrinking Databases

    1. Log in to the TencentDB for SQL Server console. In the instance list, click an instance ID or Manage in the Operation column to access the instance management page.
    2. On the Database Management tab, select the rows of the databases to be shrunk and click Batch Management > Batch Shrink Databases at the top of the list.
    3. The pop-up window displays the database names and the ratios of remaining space. Currently, only shrinking to 10% of the free space is supported.
      Note:

      Only 10% of the database's free space will remain once it has been shrunk. However, if 10% of free space is less than 2 GB, the free space will be shrunk to 2 GB.
