More memory utilised by SAP ABAP instance zones on Solaris 10

[Former Member]

Hi All,

We have this Solaris box which throws a WARNING during health_check.

fs4283# /usr/contrib/uxmon/libexec/check_health

WARNING: found error messages in /var/adm/messages: inetd: Unable to fork;<br>checked: prtdiag, psrinfo, Disksuite, zpool, syslogd, sshd, keyswitch(MAINTE.), hrdconf, /.forward, mqueue, telnetd patch, ipnodes, procs

The prstat -Z returns:

41 92 21G 2608M 4.0% 115:59:18 0.1% usai1sts

There is only 5 GB swap space free on the host fs4283. Thats why the warning.

All are application instances of different ABAP only systems.

Is it possible to reduce the SWAP utilization by the SAP instance? And is there any possibility to check

if any paritcular process in the instance occupies more swap?

Please suggest!

Regards,

Sushma

An application such as SAP doesn't use "swap", it uses memory. On memory shortage old memory pages are paged out into the swap area.

You will need to reconfigure the installations on the zones so they consume less memory (e. g. decrase sga_max on all systems if you use Oracle).
