Kernel param resizing

Nappy_1 — Fri, 01 Feb 2008 14:55:41 GMT

an Oracle DBA colleague told me to set the following kernel parameters to "unlimmited"
to solve an oracle issue related tp OC4J

cputime
filesize
datasize
stacksize
coredumpsize
descriptors
memoryuse

Do you think that this will cause any impact on the system ?

Very little since they aren't kernel parameters and kernel parameters typically do not allow a value of "unlimited". Some of them can be set in ulimit for each user, but I think you need a clearer definition of exactly what your colleague thinks should be changed.

I would recommend to get a precise value that just "ulimited"

You cant get the "ulimited" as there are dependecny with kernel parms.. Like datasize/stcksize depends on maxdsize/maxssize. Also maxssiz_64bit/maxdsize_64bit depend on the if the aplication is 64bit or 32 bit.
