Hi all!
Working on Oracle v8i/9i on Unix Sun Solaris v8.0.
I am experiencing excessive paging & Swapping.Would like to know the cause.
I guess:could be due to inappropriate setting of Unix Kernel Parameters...
Please correct me if I am wrong!
Thanks&Regards,

Hi Guys: Would like to know how to check system swapping and paging and some theory on how they function. I am an oracle dba and my environment is 8171 on AIX 433. We have a 1GB of RAM on the box and I am educating myself to see how much more SGA can be accommodated on the box and what are the... (2 Replies)
Hello!
Why does my SuSE GNU/Linux machine swap?
I have a Gig of ram, currently 14MBs of free RAM, 724MB - buffers and caches...
That is 685MB of cached RAM, then kernel really should'nt have to swap, It should release cached memory in my thinkin...
It has only swaped 3MB's but still,... (3 Replies)
can anybody explain me the concepts
virtual memory mangement, swapping and paging?
although i roughly know what they are , i need
more solid distinction between them, and also i want to figure out
the relations between them?
do you have any well-defined definitons for this concepts? (2 Replies)

ks_update
ks_update(9E) Driver Entry Points ks_update(9E)NAME
ks_update - dynamically update kstats
SYNOPSIS
#include <sys/types.h>
#include <sys/kstat.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
int prefix_ks_update(kstat_t *ksp, int rw);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
PARAMETERS
ksp Pointer to a kstat(9S) structure.
rw Read/Write flag. Possible values are
KSTAT_READ Update kstat structure statistics from the driver.
KSTAT_WRITE Update driver statistics from the kstat structure.
DESCRIPTION
The kstat mechanism allows for an optional ks_update() function to update kstat data. This is useful for drivers where the underlying
device keeps cheap hardware statistics, but extraction is expensive. Instead of constantly keeping the kstat data section up to date, the
driver can supply a ks_update() function which updates the kstat's data section on demand. To take advantage of this feature, set the
ks_update field before calling kstat_install(9F).
The ks_update() function must have the following structure:
static int
xx_kstat_update(kstat_t *ksp, int rw)
{
if (rw == KSTAT_WRITE) {
/* update the native stats from ksp->ks_data */
/* return EACCES if you don't support this */
} else {
/* update ksp->ks_data from the native stats */
}
return(0);
}
In general, the ks_update() routine may need to refer to provider-private data; for example, it may need a pointer to the provider's raw
statistics. The ks_private field is available for this purpose. Its use is entirely at the provider's discretion.
No kstat locking should be done inside the ks_update() routine. The caller will already be holding the kstat's ks_lock (to ensure consis-
tent data) and will prevent the kstat from being removed.
RETURN VALUES
ks_update() should return
0 For success.
EACCES If KSTAT_WRITE is not allowed.
EIO For any other error.
