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)

kstat_chain_update
kstat_chain_update(3KSTAT) Kernel Statistics Library Functions kstat_chain_update(3KSTAT)NAME
kstat_chain_update - update the kstat header chain
SYNOPSIS
cc [ flag... ] file... -lkstat [ library...]
#include <kstat.h>
kid_t kstat_chain_update(kstat_ctl_t *kc);
DESCRIPTION
The kstat_chain_update() function brings the user's kstat header chain in sync with that of the kernel. The kstat chain is a linked list of
kstat headers (kstat_t's) pointed to by kc->kc_chain, which is initialized by kstat_open(3KSTAT). This chain constitutes a list of all
kstats currently in the system.
During normal operation, the kernel creates new kstats and delete old ones as various device instances are added and removed, thereby caus-
ing the user's copy of the kstat chain to become out of date. The kstat_chain_update() function detects this condition by comparing the
kernel's current kstat chain ID (KCID), which is incremented every time the kstat chain changes, to the user's KCID, kc->kc_chain_id. If
the KCIDs match, kstat_chain_update() does nothing. Otherwise, it deletes any invalid kstat headers from the user's kstat chain, adds any
new ones, and sets kc->kc_chain_id to the new KCID. All other kstat headers in the user's kstat chain are unmodified.
RETURN VALUES
Upon successful completion, kstat_chain_update() returns the new KCID if the kstat chain has changed and 0 if it has not changed. Other-
wise, it returns -1 and sets errno to indicate the error.
ERRORS
The kstat_chain_update() function will fail if:
EAGAIN The kstat was temporarily unavailable for reading or writing.
ENOMEM Insufficient storage space is available.
ENXIO The given kstat could not be located for reading.
EOVERFLOW The data for the given kstat was too large to be stored in the structure.
