Hi Vijay,

I didn't find about Lazy Swap in this document. May be in different way.

I reverify in the doc.

Hi Rajesh,

check the contents of

/usr/share/doc/11.00RelNotes

and look for "Lazy Swap".
I think it is enabled by chatr +z and not by a kernel parameter.

Refer to that doc for more info and also man chatr.

HTH.

Best regards,

Lazy swap can be enabled for a particular binary (using chatr) or for particular virtual objects (using flags like MAP_NORESERVE with mmap).

There is no kernel tunable to force all allocations to be lazy swap.
