Monitor the Performance of Oracle Parallel
Server
The following is a handy script for capturing DLM performance in
an OPS environment. It then places the output inside an Oracle
table for tracking. This script includes a sophisticated use
of the UNIX date function.
This script checks the OPS values for locks, resources and
processes using the UNIX Oracle lkdump command. Once these
values have been collected, they are directed to the $RPT_FILE UNIX
directory. They are also written to the STATSPACK extension
table stats$dlm_stats.
DAY_OF_WEEK=`date
+"%A"`
MACHINE_NAME=`hostname`
RPT_FILE=/u01/MYSID/reports/dlm_monitor.${MACHINE_NAME}.${DAY_OF_WEEK}.log
# \
#
Set up the file to log the lock to:
# /
TIMESTAMP=`date
+"%C%y.%m.%d-%H:%M:%S"`
DLM_RESOURCES=`/oracle/MYSID/bin/lkdump
-a res | head -2 | awk 'getline'`
DLM_LOCKS=`/oracle/MYSID/bin/lkdump -a lock | head -2 | awk
'getline' `
DLM_PROCESS=`/oracle/MYSID/bin/lkdump -a proc | head
-2 | awk 'getline'`
printf "$TIMESTAMP $DLM_RESOURCES
$DLM_LOCKS $DLM_PROCESS \n" >>
RPT_FILE
RES=`echo
$DLM_RESOURCES|cut -f2 -d '='`
LOC=`echo $DLM_LOCKS|cut -f2 -d
'='`
PRO=`echo $DLM_PROCESS|cut -f2 -d '='`
ORACLE_SID=MYSID;
export ORACLE_SID;
