Monitor Performance of Oracle Parallel Server

Oracle Database Tips by Donald BurlesonAugust 27, 2015

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"`

# \
#   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'`

RES=`echo $DLM_RESOURCES|cut -f2 -d '='`
LOC=`echo $DLM_LOCKS|cut -f2 -d '='`
PRO=`echo $DLM_PROCESS|cut -f2 -d '='`

PATH=$PATH:/oracle/MYSID/bin; export PATH;

$ORACLE_HOME/bin/sqlplus <<! >> /dev/null

connect system/manager;

insert into perfstat.stats$dlm_stats
 values (
   $LOC );
