ds35webdriver fails to execute about ds35

[toddmuirhead]

Thanks for using DVD Store. I am happy to help you get DVD Store running. A few questions:

This tool is a database testing or benchmark tool. While it might be possible to create huge files on a remote linux system - this is not really the main point. Are you attempting to test postgresql database? Postgresql database and a php web tier?

Can you please provide the contents of your driverconfig.txt file?

Please try running it from a normal windows command prompt. It appears that you are running from an ActiveState-Perl windows command prompt and I'm not sure of how that environment will behave.

Thanks - Todd

Thanks for the response.

Please find the content of the Config file attached below.

We are using this for database application testing. As part of that we are loading huge files into the database.

Sure. I'll try from normal windows command prompt.

Are there any major differences between ds and s35? Do you recommend us to use ds instead?

[toddmuirhead]

There were many enhancements with the new ds35 version that are detailed in the readme. Essentially it was enhanced to be able to do parallel loading and multiple stores per database. ds35 is the recommended version to use.

If you are still having problems running, I would suggest removing the linux_perf_host setting. I think that might be having the issue.

I would also recommend increasing the size of the database to something larger than 10MB. The Install_DVDstore.pl script will create any size load files that you specify. You will then need to run the create_all script for postgres to get the tables created and loaded in your postgres database. Modify your parameter file to match the size db that you created.

Thanks - Todd

Thanks. Okay. Parameter file as in the config file?

Also, are there any stats about how much time does it take for 1GB/1TB files to be uploaded?
And is there any limit on the number of Linux/Windows remote hosts that can be used in one run?

[toddmuirhead]

Yes - the config file / parameter file is the same thing.

I do not have any measured stats on time for uploading files of specific sizes. The time will depend on many factors including the speed and type of network as well as the speed of the disks reading and writing the data on both ends.

I'm not entirely sure what you are asking about in terms of number of remote hosts. I have run tests against as many as 20 or 30 small VMs at the same time. I have also completely stressed several physical hosts as part of the same test. I often use scripts to coordinate running many ds35driver programs at the same time against different targets.

Thanks - Todd
