AWR your UBE. Performance investigation with JD Edwards (JDE) oracle database and UBEs

This is pretty cool, if I do say so myself.

Have you ever wanted a little more oracle performance information out of your UBEs?  I know logging is good, but AWR is better for performance.

Here are some basics for you (but this could be taken to a whole other level!).

Firstly, the basics of AWR:

create a snaphot, create another one and then create a report based upon the first and second snaphots – RAD!

create

EXEC DBMS_WORKLOAD_REPOSITORY.create_snapshot;

run UBE

runube JDE JDE PY900 *ALL $1   $2     QBATCH     Interactive Hold Save

create

EXEC DBMS_WORKLOAD_REPOSITORY.create_snapshot;

Let’s put that into a simple korn shell script:

if [ $# -ne 2 ]
  then
   echo "USAGE: $0 REPORT VERSION"
   exit
fi
sqlplus JDE/JDE@JDETEST <<EOF
EXEC DBMS_WORKLOAD_REPOSITORY.create_snapshot;
select max(snap_id)
from
    dba_hist_snapshot ;
quit;
EOF
time runube JDE JDE PY900 *ALL $1   $2     QBATCH     Interactive Hold Save
sqlplus JDE/JDE@JDETEST <<EOF
EXEC DBMS_WORKLOAD_REPOSITORY.create_snapshot;
select max(snap_id)
from
    dba_hist_snapshot;
quit;
EOF


I like to start simple, then get complex.

This is cool.  It’ll snap and tell you the ID, it’ll run the job and tell you how long it took to run and then it will snap again and tell you the next id – coolio

But I want more and neater.

So now:

if [ $# -ne 2 ]
  then
   echo "USAGE: $0 REPORT VERSION"
   exit
fi
sqlplus JDE/JDE@JDETEST <<EOF
set feedback off
EXEC DBMS_WORKLOAD_REPOSITORY.create_snapshot;
select 'START##' || max(snap_id)
from
    dba_hist_snapshot ;
quit;
EOF
echo $1_$2 RUNNING##
time runube JDE JDE PY900 *ALL $1   $2     QBATCH     Interactive Hold Save
sqlplus JDE/JDE@JDETEST <<EOF
set feedback off
EXEC DBMS_WORKLOAD_REPOSITORY.create_snapshot;
select 'FINISH##' || max(snap_id)
from
    dba_hist_snapshot;
quit;
EOF

This is a little easier – because the output looks like:

you call it like this:

./runme.ksh R30812 F4109 >> R30812_F4109.out 2>&1

and the output looks like:

You just need to awk through the output to find ## and grep –v ‘FINISH## and you’ll feed those results into the next script.

Right, but I want to parameterize this, I don’t want to enter in the snaps.

SELECT
    output
FROM    TABLE(dbms_workload_repository.awr_report_text ((select dbid from v$database),(select instance_number from v$instance),112,113 ));

So then I can automate the output too!

./runme.ksh R0010P XJDE0001 >> R0010P_XJDE0001.out 2>&1

The following bad boy will create the AWR report for you.

if [ $# -ne 2 ]
   then
     echo "USAGE FROMSNAP TOSNAP"
     exit
fi

sqlplus JDE/JDE@JDETEST <<EOF
SELECT
     output
  FROM    TABLE(dbms_workload_repository.awr_report_text ((select dbid from v\$database),(select instance_number from v\$instance),$1,$2 ));
quit;
EOF

Putting it all together, you can now grep though the output of your script.

extra for experts

If you wanted to be totally RAD, you could actually create a script and call it runube (but make it a korn shell script).  Basically it would call your stuff and then the actual runube later.  You could put all of the AWR magic in there also, so that you could have AWR’s for all of your reports.  Note that it might be a bit messy because of other transactions, but you’d get the hint about the performance and you’d know which snaps to use for what reports.
