how to enable a disabled datafile

edited May 28, 2020 12:15PM in Database Administration (MOSC) 7 commentsAnswered ✓

Hi everyone

I'm having an issue with a datafile that shows as ONLINE in v$datafile

Yet, i can't query tables underneath it.

When looking further, I realized the ENABLED column indicated DISABLED

SQL> select file#, status, enabled from v$datafile where file# in (6,7,8)

     FILE# STATUS  ENABLED
---------- ------- ----------
         6 ONLINE  DISABLED
         7 ONLINE  DISABLED

         8 ONLINE DISABLED

What does that mean and what's the way around this ?

Your help is much appreciated

Howdy, Stranger!
