top output problem & buffer cache

[bhavin asokan]

hi,

1st problem :

in my top output the average always shows the same output.only load column is getting changed.the cpu,sys,user average are always same.


CPU LOAD USER NICE SYS IDLE BLOCK SWAIT INTR SSYS
0 0.00 0.8% 0.0% 1.0% 92.4% 0.0% 0.0% 0.0% 0.0%
1 0.06 0.4% 0.0% 0.6% 96.4% 0.0% 0.0% 0.0% 0.0%
avg 0.03 -0.0% -0.0% -0.0% 100.0% -0.0% -0.0% -0.0% -0.0%


2nd problem:

in this system total memory is 2.5gb
now system is using average 155mb and user it is 950mb average.

my problem is with buffer cache.dbc_min_pct and dbc_max_pct is set to 2% .but in glance buffer cache it is always showing 7.8mb .why it is like this.as per configuration it should be minimum 50mb.any patch is there to solve this.

Hi Bhavin,

1 - In my (almost) inactive server I also have something like this on top:

Cpu states:
LOAD USER NICE SYS IDLE BLOCK SWAIT INTR SSYS
0.79 0.0% 0.0% 0.2% 99.8% 0.0% 0.0% 0.0% 0.0%

This is because the server has almost no activity: just a Test environment...


2 - You should increase the buffer cache to something like 300 Mb. About Glance output I can't answer...

hi,

my server is not an inactive server.it is used as a backup server to my main server.sybase database & replication server is running on that server.

check the top output.
the 1st cpu is used nearly 8%. 2nd cpu is used 4%.the average should show nearly 95%(but shows 100%).even if the cpu idle values changes to other values,it shows 100% only.

Hi,

You are right, the load, nice and sys averages are not ok.

Do you have PHCO_29072 installed (I supose you are on 11i?)
