Timing queue jobs

Martin Brindle — Mon, 26 Feb 2007 08:31:44 GMT

I need to perform some simple performance timing of a batch job submitted to the batch queue. How is it possible to monitor when a job has completed and print a start and end time?

Thanks in advance.

If you have enabled the accounting, you will get some info.

$ show acc
will tell you if you have accounting enabled

If it is, you can get some info with
$ acc/fu/since=16:00/bef=17:00/out=a.tmp
if you job has run between 16:00 and 17:00

You can refine with
/user=myuser
/queue=my_batch_queue
...

The best thing is to prepare some tools before you run the process

You can find pquota.exe at
http://h71000.www7.hp.com/freeware/freeware40/pquota/

Put it somewhere, e.g. in disk:[dir]
define a symbol
$ pquota :== $ disk:[dir]pquota.exe
then you can do
$ pquota 204002B4
if you want to see the resources used by this process

Martin,

if this batch job does have a log file, you can easily find the start and end date with:

$ DIR/DATE=(CRE,MOD) batch-log-file.LOG

Thanks for the responses. However, I realised the answer was in my question, so I came up with this, which I called timer.com

$ SHOW TIME
$ @'P1' 'P2' 'P3' 'P4' 'P5' 'P6' 'P7' 'P8'
$ SHOW TIME

I then ran timer.com passing the name of the script to benchmark as the first parameter and then subsequyently all of it's parameters behind. It seems to work really well.

Martin,

this might be more than you want, but if you add this to SYS$SYLOGIN:

$ if f$getjpi("","mode") .eqs. "BATCH"
$ then
$ set prefix "!11%T "
$ endif

than the DCL "prompt" in the LOG files will be the first 11 chars of the time (hh:mm:ss.cc) of the time that line is executed.

We simply LOVE it for tracing performance issues!

Proost.

Have one on me.

I have attached my MEASURE.COM procedure which outputs elapsed time, I/O counts, page faults and CPU use for any command line.

@MEASURE a command line up to 8 parameters
Elapsed secs: 2.90 DIO: 20 BIO: 4461 PGF: 82 CPU: 0.16
