Hi Managers,
Thanx to Tom Blinn and B.L. Venkatesh for their replies.

The consenus seems to be that UBC was not implemented until V5.1b and
I am using V5.1 (something I forgot to mention in the original mail).

Thanx.
Dp.

Hi Managers,

DS10, advfs file system.

I was looking at the output from dbx,`pd bio_stats` and it is showing
zero hits. That doesn't seem right or does the UBC not apply to ADVFS
file systems.

struct {
    getblk_hits = 0
    getblk_misses = 2
    getblk_research = 0
    getblk_dupbuf = 0
    getnewbuf_calls = 2
    getnewbuf_buflocked = 0
    vflushbuf_lockskips = 0
    mntflushbuf_misses = 0
    mntinvalbuf_misses = 0
    vinvalbuf_misses = 0
    allocbuf_buflocked = 0
    ufssync_misses = 0

Thanx.
Dp.
