limits values in sapcontrol and jvmmon are different

Dear experts,

In note 1827960 - Operating system limits for SAP instances we know the limits set in command line maybe different from the values used by SAP. Follow the note, we set the values in /usr/sap/sapservices and restart the system following the note. (OS is HPUX 11.31)

This is what we set:

limit.descriptors=unlimited

limit.stacksize=unlimited

limit.datasize=unlimited

Now by running:

> sapcontrol -nr <instance nr.> -function OSExecute "/bin/ksh ulimit -a" 0 0

time(seconds)        unlimited

file(blocks)         unlimited

data(kbytes)         unlimited

stack(kbytes)        unlimited

memory(kbytes)       unlimited

coredump(blocks)     4194303

Looks like missing nofile. So we run sapcontrol with csh:

> sapcontrol -nr <instance nr.> -function OSExecute "/usr/bin/csh -c limit" 0 0

cputime         unlimited

filesize        unlimited

datasize        unlimited

stacksize       unlimited

coredumpsize    2097151 kbytes

descriptors     8192 files

memoryuse       unlimited

But with jvmmon + dump hs_err_info

We found this:

rlimit: STACK infinity, CORE 2097151k, NPROC 4097, NOFILE 63488, AS infinity, DATA infinity

This is what we got from command line with <sid>adm user:

cputime         unlimited

filesize        unlimited

datasize        4194300 kbytes

stacksize       392192 kbytes

coredumpsize    2097151 kbytes

descriptors     8192 files

memoryuse       unlimited

Quite confused about which value is really used by JVM. Any idea on this? Thank you

Regards,

Donny
