I have an Ultra 30 with a 250Mhz processor and 640mb of memory. Solaris 8
with latest recommended patches Swap info is
swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0t0d0s3 32,3 16 1080864 1080864
The system is running 4 IBM applications, db2, network dispatcher (edge
server), IHS (apache), and Secureway directory servers (ldap).
Basically, about every other week or so, the system goes into pretty much a
"hung state". I can connect to the box, but it is extremely slow to run
commands, etc. Below are some ps and vmstat results while the system is
hung. As you can see, the system goes a little haywire with disk utilization
and memory utilization. I have to reboot to get the system normal for another
two weeks. Has anyone ever had problems like this.
My gut feeling is that there are too many db2 processes running and using a
lot of memory and the system is basically not powerful enough for these
applications. Sun has said the same, IBM has had me patch/tune some of the
apps.
If anyone has any thoughts, it would greatly be appreciated.
