Re: kernel tuning issue
Depending on how you performed the 'kctune', you might just reboot (or reboot using the previous kernel configuration).
It seems that you ignored several constraints. It's not good to fool Mother Nature.

Re: kernel tuning issue
Or you may have to reduce some of the value before you can increase the others.
Have you tried printing out the values of all of these parms?

Re: kernel tuning issue
Try to update the parameters in SAM, it has help for each parameter, which has dependencies.

Re: kernel tuning issue
You will never enforce these values. Configure it with SAM, it will show you the formula and the suggested value.

Re: kernel tuning issue
Best practice to change the kernel parameter is to save the old copy of kernel as date_old.
Change the kernel parameters in SAM,
calculate it, before it changes then if the value is correct to set and its dynamic parameters it will be changed, if not it will show u the dependices of other parameter with relation tht greater than or less than equal to particular parameter is depends.
Hope this solves ur query.
