HP-UX Workload Manager A.03.00 Release Notes for HP-UX 11i v1 and HP-UX 11i v2

HP-UX Workload Manager Release Notes

Known problems and workarounds

WLM configurations cannot be activated when there is less than

100 Mbytes of available memory

Issue

When you have WLM controlling memory, it gives each workload group 1%

of the memory when a configuration is activated and then adjusts the

percentage for workload groups with active SLOs based on settings in the

configuration.

However, WLM requires that the initial 1% of memory represent at least 1

Mbyte. On systems with less than 100 Mbytes of available memory, that 1%

is less than 1 Mbyte. As a result, WLM cannot activate the configuration in

this case.

Workaround

Increase the system’s memory or decrease the minimum dynamic buffer

cache using the kernel parameter dbc_min_pct.

Secure Resource Partitions:

Blocked port on a virtual network interface

Issue

Using the HP-UX feature Security Containment, you can set up a virtual

network interface for each secure compartment. A process in one secure

compartment can bind to a socket on a virtual network interface associated

with a different secure compartment. Although this process will not be able

to accept connections or use the socket to send or receive data, it does

prevent other processes from binding to that socket.

Workaround

Be sure your applications that access the network bind only to sockets on

the virtual network interface created for their respective secure

compartments.

HP-UX 11i Security Containment Administrator’s Guide.
