:schema existence check error handling occurred during DTS PreCheck

Last Updated:Jan 16, 2023

Problem description

When you use DTS to migrate data to an RDS instance, schema existence check error.

Causes

As mentioned in the error message, the error is caused by a nonexistent or mismatched target Library.

Solution

You must create a destination database in the destination RDS instance. The destination database has the same name as the source database. Follow these rules:
  • The database name must contain lowercase letters, digits, underscores (_), and hyphens (-). It must start with a letter and end with a letter or digit. Note that the database name is case-sensitive.
  • If the names of the source and destination databases are different, you can modify the names of the databases to be migrated during the DTS migration.
  • This error is often accompanied by an error message about target Database permissions check, because the target database has not been created or is abnormal. The error is also resolved after the target database configuration is complete.

Application scope

  • Data Transmission Service
