Oracle RAC
Use Huawei Storage Interoperability Navigator to query the supported Oracle versions.
To reduce private network traffic and improve database performance, the following configurations are recommended.
- Application partition: Run different applications on different RAC instances for application isolation.
- Data partition:
- Partition tables according to the application types.
- Place the data that can be read only or the data that can be read only in a certain period into the read-only table space.
- Principles of planning Automatic Storage Management (ASM) disk groups:
- Store different types of files in different ASM disk groups.
- If there are a large number of systems using the group by query statement, create an independent ASM disk group for the temporary table space.
- Dedicate two ASM groups respectively to the file where system table space and recovery table space reside and the file where user data resides.
- If there are no special requirements on high availability, you are advised to apply EXTERNAL redundancy policy to all disk groups except the one where Oracle RAC files reside and use RAID2.0+ and active-active technologies of Huawei storage for data protection.
