hello,

i'm using the performance tuning tool through the IDE and this is working fine with most configurations in my project.

but for one of them, the tuning process seems to go along nicely until the end.

i even get this promising message:

> Default test: Deterministic time = 226309.20 ticks
> Best test: 'long_test1'  Deterministic time = 46260.38 ticks

but the resulting .ops file (with the best parameters settings for my configuration) is nowhere to be found.

has anyone seen this before?

for information, i'm using Cplex v 12.6

thanks for your help.

regards

Hi,

have you tried to open a support ticket at https://www.ibm.com/support/home/

?

thanks for the tip alex.

i have followed your link and entered "Cplex" in the product and support search engine.

i selected IBM ILOG Cplex optimisation studio and was then redirected to IBM's "new support experience".

there, i was faced with an empty list of discussion topics with no possibility to open a case (refer to attached screenshot).

so no luck there i'm afraid.

Hi,

and if you go directly to

https://www-947.ibm.com/support/servicerequest/prodCompSelect.action

?

regards

hi,

if i do , i get to select the product i need support for and when i select "CPLEX Optimizer for z/OS 12.6.0", i end up on the "new support experience" link again...

Could you try to reset the history/cache/cookies of your web browser? Try with a different browser maybe?

If you still have the issue, please report by clicking on "provide feedback" on the bottom of the mysupport page. This is the best way to report problems with the website.

thank you all for your help on cretaing support tickets but i wouldn't mind if we could refocus on the initial question (why is the perf tuning tool not generating the config file?)

nic

I will check internally whether such case was already hit. In the meantime, here are two ideas to try to narrow down the issue:

- One way is to try a newer version. 12.6 is already 4 years old, and it could very well be that this issue was already fixed long ago.  You may want to refer to this announce in order to get 12.8 instead.

- You could try to export your model to a CPLEX format (SAV, LP or MPS), and run the tuning tool in the CPLEX Interactive. If you can reproduce the issue this way, it will be easier to investigate.

I would very much appreciate if you could help us solve this "can't create as support ticket" issue that was identified.  If you have a commercial CPLEX license (i.e. you're not using it through the Academic Initiative program), then you should definitely be able to open a support request. In that case, would you please send me an email at [firstName] dot [lastName] at fr dot ibm dot com?

Can you try with oplrun? Te command line should be something like   oplrun -tune  file_to_produce.ops -p project_to_run  and it should create the file in the project directory.

oplrun should output 

<< Tuning progress 100.0%  remaining 0.0s >>>

<<< tune params: xxx.ops

Otherwise it means something wrong happened in OPL or CPLEX.

thanks Vincent,

the tuning worked with oplrun, and it did produce the output file.

no idea what the problem is with the IDE...

 oplrun -tune  file_to_produce.ops -p project_to_run

processes all run configs by default I think, so if one of them gives a result, the file will be created, but in this

case tuning is for all run configs, not only the one you want (selected in IDE wizard)

In order to make it similar to the IDE processing in your screendump you have to specify the run config, as in :

 oplrun -tune  file_to_produce.ops -p project_to_run "Model 9 10mHz"

If there is no result, the IDE does not create the result.

And the IDE basically calls the same code as oplrun, so there should be no difference between the two

hi Frederic,

I did specify the run config in my command line :

         C:\XXXX>oplrun -p "C:\Dev\FleX.Hub - Multi-Site SSY\FCR Pool Opt\Optim Engine" "Model 9 10mHz"

so the tuning was indeed done for the one selected in IDE wizard.

do you mean

C:\XXXX>oplrun -tune result.ops -p "C:\Dev\FleX.Hub - Multi-Site SSY\FCR Pool Opt\Optim Engine" "Model 9 10mHz"

?

sorry, yes.

Then I have no idea what can go wrong in the IDE, it calls the same code as oplrun.

do you delete result.ops before running oplrun ? (to make sure it is created by tuning)

Do you have something in the .log file (<workspace>/.metadata/.log) ?

It could be a file not found or something like that.
