file open/read/write/close/access by process

Hi

want to know what file (descriptor+filename+socket) is being accessed [open,read,write,seek,lseek,close etc] by particular process on solaris.

Purpose : while running perf. test, needs to find where is the bottleneck.

We are providing concurrnet load for around 1 hr and needs to capture data related to file usage pattern by java(its weblogic on sol 10)

one thing is using truss/strace etc, however any good script/tools already avail ?

Not : lsof is not useful, as lsof will give open file at a time, we needs to capture all file related operation for given time period.

NAME
pcap_set_tstamp_type - set the time stamp type to be used by a capture device SYNOPSIS
#include <pcap/pcap.h> int pcap_set_tstamp_type(pcap_t *p, int tstamp_type); DESCRIPTION
pcap_set_tstamp_type() sets the the type of time stamp desired for packets captured on the pcap descriptor to the type specified by tstamp_type. It must be called on a pcap descriptor created by pcap_create() that has not yet been activated by pcap_activate(). pcap_list_tstamp_types() will give a list of the time stamp types supported by a given capture device. See pcap-tstamp(7) for a list of all the time stamp types. RETURN VALUE
pcap_set_tstamp_type() returns 0 on success if the specified time stamp type is expected to be supported by the capture device, PCAP_WARN- ING_TSTAMP_TYPE_NOTSUP on success if the specified time stamp type is not supported by the capture device, PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device doesn't support setting the time stamp type.
