How to monitor dbc_max_pct utilization in 11.11i

How to monitor dbc_max_pct utilization in 11.11i

Hi all,

is it possible to monitor the dynamic buffer cache utlization (dbc_max_pct)any how..
my system is deficiating on memory, i see that
more jobs are already waiting for i/o, but i am not sure about the buffer cache utilization,
i want to reduce it's value to 25 so as to free some unused buffer memory.

If you have a copy of kmeminfo that will tell you. On my 11.11 system I have a copy in /usr/contrib/Q4/bin/

Of course its not a formally supported tool, so if you don't have it you'll need to ask the response centre for it...

Maybe this can help.

I monitor things like that using glance and cron:

glance -iterations 1 -adviser_only -syntax ./threads.glance > threads.log

where threads.glance is like this:

PRINT "Total Physical Memory: ", gbl_mem_phys, " ", gbl_mem_phys*.001,"mb"

Probably you can do the same with dbc_max_pct.

If you have glance and you run glance live, it shows the buffer cache usage in two places. One is on the "top bar" on the memory line, it is the horizontal bar between the two B's
The second place is in the main memory screen that you get when you hit the "m" key.
