"too many data files to add in one command"
*Cause: The command specifies adding more data files than can be done in
one command. It is necessary to fit all the file names into one
log entry, but that would make the entry too large.
*Action: If this is a CREATE TABLESPACE command, create with fewer files
then add the other files later. If this is an ADD DATAFILE command,
break it up into multiple commands.
