In the past I have been a little critical of Oracle’s support notes and documentation regarding the use of Advanced Format 4k storage devices. I must now take that back, as my new friends in Oracle ASM Development and Product Management very kindly offered to let me write a new support note, which they have just published on My Oracle Support. It’s only supposed to be high level, but it does confirm that the _DISK_SECTOR_SIZE_OVERRIDE parameter can be safely set in database instances when using 512e storage and attempting to create 4k online redo logs.
The new support note is:
Using 4k Redo Logs on Flash and SSD-based Storage (Doc ID 1681266.1)
Don’t forget that you can read all about the basics of using Oracle with 4k sector storage here. And if you really feel up to it, I have a 4k deep dive page here.
