Which Items Occupy the Storage Space of DDS Instances?

The following types of data will occupy the storage space:

  • The storage space you applied for will contain the system overhead required for inode, reserved block, and database operation.
  • User data (backups not included)
  • Data required to ensure instances run properly, such as system database data, rollback logs, and search indexes.
  • Log output files that are generated by DDS ensure the stable operating of DDS instances. For example, Oplogs occupy 10% of storage space and cannot be resized.
