Suggestions

If you are using an ApsaraDB RDS for PPAS instance, you can go to the Data Transmission Service (DTS) console to migrate data from your ApsaraDB RDS for PPAS instance to a PolarDB for Oracle cluster. For more information, see Migrate data from an ApsaraDB RDS for PPAS instance to a PolarDB for Oracle cluster.

When you migrate data from your ApsaraDB RDS for PPAS instance to a PolarDB for Oracle cluster, take note of the following items:
  • Make sure that the specifications of the PolarDB for Oracle cluster are higher than or equal to the specifications of your ApsaraDB RDS for PPAS instance. Otherwise, slow SQL queries or out of memory (OOM) error may occur because of insufficient CPU or memory resources after you migrate the data to the PolarDB for Oracle cluster. For more information about recommended specifications of PolarDB for Oracle clusters, see Mapping between specifications of ApsaraDB RDS for PPAS instances and recommended specifications of PolarDB for Oracle clusters.
  • If you have special requirements for the number of connections and IOPS after migration, select appropriate specifications based on your business requirements. For more information, see Specifications of PolarDB for Oracle cluster.
  • If you use a cluster endpoint to connect your application to a PolarDB for Oracle cluster, read/write splitting is enabled. Then, the system forwards read requests to read-only PolarDB for Oracle nodes. This reduces the loads on the primary PolarDB for Oracle node. For more information about how to obtain a cluster endpoint, see View or apply for an endpoint.
