To use the Public Network Access method, users must choose the region closest to their physical database's region when purchasing a DTS task, and then use DTS for the transmission task. For example, If the region of the physical database is not included in the service regions of DTS, then choose a DTS service region that is closest to the region of the physical database. This ensures the optimal transmission path for DTS, reducing the duration of data transmission.
DTS supports using the local IDC database as a source/destination for data transmission, as shown in the examples below.
Scenario Two: Local IDC Database (Public Network ) -> Local IDC Database (Public Network)
DTS Task Configuration
The following explains configuration instructions using Scenario One as an example.
1. When a DTS task is purchased, select the DTS region closest to the source database as the Source Instance Region. Select the region where the target database is located as the Target Instance Region, i.e., A.
2. When a DTS task is configured, in the source database and target database settings, select public network as Access Type.
3. Connectivity Test
If the database and its associated network have configured security access rules, such as security groups, firewall, IP access restrictions, etc., it is necessary to allow DTS IP address, otherwise, connectivity test may fail.
Allow DTS Service IP
1. When the connectivity test fails, follow the instructions in the popup to access "DTS Service IP".
2. Sequentially check if the database has set the following network rules, and if yes, allow DTS Service IP in the corresponding rules.
Check if network ACLs or security groups are set for the database-associated network layer.
Check if the firewall is set for the server layer where the database resides (e.g., iptables rules for Linux systems).
Check if IP access restrictions are set for the source database layer.
