Frequently Asked Questions
Do I need Oracle Client to connect ClearSQL to a database?

Can I install ClearSQL on Mac?
We don't provide Mac-native versions of our tools, but you've got plenty of options, which are successfully applied by many of our mac-based users.

  1. All the tools are tested in a virtual environment. You can install it with an Oracle Client to VMWare, VirtualBox, Parallels. Even Documenter, which is resource-critical runs with a minor overhead (±1%).
  2. Some users report successful launches with Wine, though we haven't tested it on our grounds.
  3. Bootcamp could also be the choice, should you prefer non-virtualized environments.
Can I run ClearSQL jobs via Jenkins?
Yes, you can, but mind the following:

— Jenkins Windows service must be started under a user account, not under a system account.
— Check the available memory heap for non-interactive applications:
  1. Open the registry value HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SubSystems\Windows.
  2. Change last three digits of the SharedSection value to 1536.
By default, SharedSection = 1024,12288,512. The last three digits differ depending on Windows version. ClearSQL requires at least 1536.

For more information, refer to Microsoft support.

After running a job, you can check the log file %APPDATA%\ClearSQL\CS.log for errors.
