export PATH
SERVER_NAME=`uname -a|awk '{print $2}'`
typeset -u SERVER_NAME
export SERVER_NAME
# sample every five minutes (300 seconds) . . . .
SAMPLE_TIME=300
while true
do
vmstat ${SAMPLE_TIME} 2 > /tmp/msg$$
# run vmstat and direct the output into the Oracle table . . .
cat /tmp/msg$$|sed 1,3d | awk '{ printf("%s %s %s %s %s %s\n", $1, $8, $9,
14, $15, $16) }' | while read RUNQUE PAGE_IN PAGE_OUT USER_CPU SYSTEM_CPU
IDLE_CPU
do
$ORACLE_HOME/bin/sqlplus -s perfstat/perfstat@testsys1<<EOF
insert into perfstat.stats\$vmstat
values (
sysdate,
$SAMPLE_TIME,
'$SERVER_NAME',
$RUNQUE,
$PAGE_IN,
$PAGE_OUT,

apache::session::oracle
Apache::Session::Oracle(3pm) User Contributed Perl Documentation Apache::Session::Oracle(3pm)
NAME
Apache::Session::Oracle - An implementation of Apache::Session
SYNOPSIS
use Apache::Session::Oracle;
#if you want Apache::Session to open new DB handles:
tie %hash, 'Apache::Session::Oracle', $id, {
DataSource => 'dbi:Oracle:sessions',
UserName => $db_user,
Password => $db_pass,
Commit => 1
};
#or, if your handles are already opened:
tie %hash, 'Apache::Session::Oracle', $id, {
Handle => $dbh,
Commit => 1
};
DESCRIPTION
This module is an implementation of Apache::Session. It uses the Oracle backing store and no locking. See the example, and the
documentation for Apache::Session::Store::Oracle for more details.
USAGE
The special Apache::Session argument for this module is Commit. You MUST provide the Commit argument, which instructs this module to
either commit the transaction when it is finished, or to simply do nothing. This feature is provided so that this module will not have
adverse interactions with your local transaction policy, nor your local database handle caching policy. The argument is mandatory in order
to make you think about this problem.
This module also respects the LongReadLen argument, which specifies the maximum size of the session object. If not specified, the default
maximum is 8 KB.
AUTHOR
This module was written by Jeffrey William Baker <jwbaker@acm.org>.
