DAOS read only

DAOS read only

I have enabled DAOS and compacted the mailfiles using compact -c -daos on.
After the compact has successfully finished, I saw that DAOS state was READ/WRITE on all files.
Today some (3 of 400) databases have a DAOS state of READONLY.
Can anyone explain what causes the change? What are the effects when the state is READONLY?

A database can have one of three DAOS states

Disabled - the database does not have any objects in DAOS and it will not store objects in DAOS
Read/Write - the database is DAOS enabled, any qualifying new objects will go into DAOS
Read Only - the database has DAOS objects and those will continue to work fine, but new objects will be written into the NSF and not DAOS because the database does not meet the criteria for using DAOS (we need to figure out what would cause this )

A database can only participate in DAOS if these criteria are met
1) the system is transaction logged
2) DAOS is enables at the server level

I assume you meet these two criteria, you can verify this by issuing a
SHOW SERVER console command
you should see
DAOS: Enabled

3) the individual database is transaction logged
4) the individual database has the DAOS property set
5) the database is ODS 51

to check this, run a
SHOW DIR directory_or_file_name

for example

> sh dir zzz

For the files in question, verify that ODS version is V8:51, Logging is Yes and DAOS is Yes.

Are any of these indicators wrong for your Read/Write databases ????? (if so, then the next step is to determine how/why)
