The db server is of 16 cores that was a typo mistake. Its has only one db instance running which finabrodb and nothing else is running on this system. The other Db psentry was also my mistake from UAT system sorry for that.
Code:
root@ABRO-DB/#lsattr -El mem0
ent_mem_cap I/O memory entitlement in Kbytes False
goodsize 204800 Amount of usable physical memory in Mbytes False
mem_exp_factor Memory expansion factor False
size 204800 Total amount of physical memory in Mbytes False
var_mem_weight Variable memory capacity weight False
root@ABRO-DB/#
For so many archive processes this need to check with dba.
the FILESYSTEMIO_OPTIONS=SETALL is not enabled. The SGA is 40Gb
I have already raise request to increase the SGA to 80Gb as memory is of 200Gb.

Hello everybody.
I have a problem with my AIX 5.3. Recently my unix shows a high cpu utilization with sar or topas.
I need to find what I have to do to solve this problem, in fact, I don't know what is my problem.
I had the same problem with another AIX 5.3 running the same... (2 Replies)
About 4 years ago I wrote this tool inspired by Rob Urban's collect tool for DEC's Tru64 Unix. What makes this tool as different as collect was in its day is its ability to run at a low overhead and collect tons of stuff. I've expanded the general concept and even include data not available in... (0 Replies)
Hello Friends,
On one of my Solaris 10 box, CPU usage shows 100% using "sar", "vmstat". However, it has 4 CPUs and prstat and glance are not showing enough processes to justify high CPU utilization.

Hi All,
While creating zone we will mention min and max cpu cores, like
add dedicated-cpu
set ncpus=NUM_CPUS_MIN-NUM_CPUS_MAX
end
Ques1:
Suppose thing that non global zone uses only minimum cores at particular time What the other cores will do, Will it shared to global zone?

There might be some problem with my server,
because every morning at 7, it's performance become bad with no DB extra deadlock.
But I just couldn't figure it out.
Please give me some advise, thanks a lot...

hi
We have migrated SCO 5.0.6 into ESX4, but the VM eats 100% of the virtual CPU.
Here is top print from the SCO VM:

We have a DB server which is constantly utilised above 95% above.
This is becoming nuisance when the monitoring team frequently calls to check on it. Frankly I do not know what to tweak or even interpret the outputs.
I noticed constant 30 to 60% in wio column of the cpu utilisation.

Hi all,
Been reading a lot of the cpu load and its "analogy of it to car traffic path of expressway"

unw_set_caching_policy
UNW_SET_CACHING_POLICY(3) Programming Library UNW_SET_CACHING_POLICY(3)NAME
unw_set_caching_policy -- set unwind caching policy
SYNOPSIS
#include <libunwind.h>
int unw_set_caching_policy(unw_addr_space_t as, unw_caching_policy_t policy);
DESCRIPTION
The unw_set_caching_policy() routine sets the caching policy of address space as to the policy specified by argument policy. The policy
argument can take one of three possible values:
UNW_CACHE_NONE
Turns off caching completely. This also implicitly flushes the contents of all caches as if unw_flush_cache() had been called.
UNW_CACHE_GLOBAL
Enables caching using a global cache that is shared by all threads. If global caching is unavailable or unsupported, libunwind may
fall back on using a per-thread cache, as if UNW_CACHE_PER_THREAD had been specified.
UNW_CACHE_PER_THREAD
Enables caching using thread-local caches. If a thread-local caching are unavailable or unsupported, libunwind may fall back on
using a global cache, as if UNW_CACHE_GLOBAL had been specified.
If caching is enabled, an application must be prepared to make appropriate calls to unw_flush_cache() whenever the target changes in a way
that could affect the validity of cached information. For example, after unloading (removing) a shared library, unw_flush_cache() would
have to be called (at least) for the address-range that was covered by the shared library.
For address spaces created via unw_create_addr_space(3), caching is turned off by default. For the local address space
unw_local_addr_space, caching is turned on by default.
RETURN VALUE
On successful completion, unw_set_caching_policy() returns 0. Otherwise the negative value of one of the error-codes below is returned.
THREAD AND SIGNAL SAFETY
unw_set_caching_policy() is thread-safe but not safe to use from a signal handler.
ERRORS
UNW_ENOMEM
The desired caching policy could not be established because the application is out of memory.
