Checking the kernel configuration on Linux and UNIX systems

Check the kernel configuration parameters on Linux and UNIX systems for prerequisite and corequisite products.

IBM® Integration Bus has no specific requirements for kernel configuration parameters; however, other products might require particular settings. If you do not tune your kernel parameters to suit the products that you have installed, you might see unexpected results or a deterioration in performance.

Follow these steps to configure your kernel parameters:

  1. Check the documented values for the following products:
    • WebSphere® MQ
    • DB2® (if it is installed)
    • Other software that you have installed to work with IBM Integration Bus, including other databases.

    You can access the relevant information for IBM products through IBM Knowledge Center.

  2. Take the highest value for each parameter and compare it to the corresponding value in your kernel configuration.
  3. If the current value is lower than the highest documented value, update the current setting by using the appropriate tooling that is supplied by the operating system provider. If the current value is higher, leave it unchanged.
  4. On Solaris, increase the maximum number of concurrent open file descriptors on your system to at least 256.
  5. If you have changed any kernel values, you might need to restart your system for these changes to take effect. Check the documentation for your operating system for further information about these parameters.
