A bigfile tablespace can only contain one datafile, so you cannot expand a bigfile tablespace across two physical disks unless you are using a virtual filesystem or Oracle ASM that makes the added space appear as part of the same disk to the database. Typically this kind of configuration must be planned in advance, before the database is created.

Your only option to use the second physical disk is to create a second, independent tablespace.

The disk size now full

That said, if your C: drive is 100% full, you may have other problems. Typically, Windows performance starts to deteriorate when the C: drive becomes too full (like over 80%), and your bigfile tablespace is designed to fill an entire disk. Placing it on the same drive with your operating system is probably not a good idea. Bigfile tablespaces should generally only be used on disks or filesystems that don't contain any other files.

  • Yes , I create webapplication for one years and don't planning for upgrade database . but the company use it to much and added to much devices so the application desigend for smb work under organazation size, I will update and set different database from os drive. That actually can't do anything right? Jun 20, 2023 at 17:37
  • It's 100% full and all the app database work perfectly until 100%, Thanks to Oracle (JAVA and ORACLE database Enterprise Edition) and 24GB RAM. Jun 20, 2023 at 17:41
  • Good to know , the disk full but all new data if restart server save in memory! (near 16GB will save) in RAM not database!!!! And all system good to go. Jun 20, 2023 at 17:43
