Oracle 10g kernel changes.

[Juan Gonzalez_2]

Oracle 10g installer is telling me that kernel parameters Maxswapchunks and semmap are missing and need to be added. I know how to change a kernel parameter on HP-UX 11.23 but I do not know how to add a kernel parameter or if one can be added.

The following says you should ignore that bogus Oracle message:

Yup... those are obsoleted by 11iv2:

[semmap went away in v2 itself]

and

[maxswapchunks went away in v1.6]

Thanks for all the good information.

Hi Juan,

Starting in 11.23 these kernel parameters are obsolete.

The workaround for this is to use kctune -u =.
# kctune -u maxswapchunks=16384

please assign points

While that will create it, there should be no need to workaround the bogus Oracle message, ignore it.
