Why is Oracle 10g R2 V$DATABASE.NAME maximum 8 characters long? -

-

i have database name contains more 8 characters, when run command select name v$database; returns first 8 characters of named database.

i noticed eight-character version somewhere during installation summary , thought down fixed table width cutting off rest of name, getting same using sql*plus.

database names in oracle limited 8 characters. if entered more somewhere else, has been truncated without notice.

as why, presumably there technical reason "back in day", , while presumably not issue anymore, limitation has been preserved sake of compatibility.
