I hope you are OK, it was impossible to ask TOM during many days...
Two weeks ago I was testing, with RMAN, the "RECOVER TABLE" command. It helped me to restore a dropped table, with RMAN backups : a very powerful and useful feature, thanks to Oracle for that tool.
I droped the table HR.ZZRMAN01 of the PDB ORCL and, to restore it, my command was :
RMAN> RECOVER TABLE HR.ZZRMAN01 OF PLUGGABLE DATABASE ORCL UNTIL SCN 2331673 AUXILIARY DESTINATION '/u01/app/oracle/RMAN_TEMP' REMAP TABLE 'HR'.'ZZRMAN01':'ZZRMAN01_PREV';
And, surprise, on the screen I saw that Oracle creates an instance named dvil...

Well, my little question is just : does Dvil mean devil? You agree with me or I am wrong?
I was so amused that I wanted to talk about it with Oracle experts :-)
Have a nice day,
I floated the question around the Product Managers and no-one knows the reason, so it looks like it was at the whim of a developer.
My *guess* would be (D)atabase reco(V)ery (I)instance (L)ight.
