Re: Script to automate AWR reports (not snapshots)

Sandra,

Maybe this helps?

It is designed to run via UNIX "cron" from a central database (here called "dwprod"), but it connects to any configured database to run AWR reports. The configuration file for the script is located in the "$HOME" directory of the UNIX account it is running under (i.e. "oracle") and is named ".run_awr" (i.e. note the leading period in the file name, to keep it "hidden"). This script uses the standard "oraenv" shell script to set up the Oracle environment in which it runs.

The format of the ".run_awr" configuration file is described in the header of the shell script.

Hope this helps...

Management is under the mistaken impression that the performance problems we are experiencing on a daily basis ALWAYS happen at the same time. To that end, they want me to set up a shell script that will run an AWR report daily for each of the two time periods they believe the problems are occuring. I haven't been able to convince them we should run reports for the times we KNOW we had problems. I also haven't been able to locate a script to automatically run reports for the specific time periods--I'm probably not entering the right search criteria. Does anyone have such a script or can point me in the right direction?

# File:         run_awr.sh
# Type:         korn shell script
# Author:       Tim Gorman (Evergreen Database Technologies -- www.evdbt.com)

#
# Description:
#       UNIX Korn-shell script to run under the UNIX "cron" utility to
#       automatically generate and email Oracle "AWR" reports in HTML against
#       the database accessed via the specified TNS connect-string, to a
#       specified list of email addresses.
#
# Parameters:
#       Zero, one, or more parameters may be passed.  These parameters
#       are TNS connect-strings, each of which refer to entries in the
#       script's configuration file (named ".run_awr", described below).
#
#       If no parameters are specified, then the script processes all of
#       the lines in the configuration file.
#
#       For each of the parameters specified, the script will process
#       each of the corresponding lines in the configuration file.
#
#       Each TNS connect-string should be separated by whitespace.
#
# Configuration file:
#       The file ".run_awr" in the "$HOME" directory contains one or more
#       lines with the following format, three fields delimited by "commas":
#
#               TNS-connect-string : recipient-list : hrs
#
#       where:
#
#               TNS-connect-string      Oracle TNS connect-string for the db
#               recipient-list          comma-separated list of email addresses
#               hrs                     "sysdate - <hrs>" is the beginning
#                                       time of the AWR report and "sysdate"
#                                       is the ending time of the AWR report
