Management Tuning Parameters
For Bundle Distribution
® ®
Novell ZENworks Configuration Management has different parameters that can be tuned for
increased bundle delivery performance. Novell has conducted extensive testing to provide default
parameters in ZENworks Configuration Management that provide the best performance for the
greatest number of customers. This section should assist customers who need to tune the product to
their specific environments.
Currently in ZENworks Configuration Management, there are three parameters that can be tuned for
optimal performance:
Section C.1, "JAVA Memory Allocation:," on page 109
Section C.2, "Threads," on page 110
Section C.3, "CLIENT RETRIES," on page 111
Section C.4, "Recommendations," on page 111
C.1 JAVA Memory Allocation:
ZENworks Configuration Management uses a 32-bit JVM. Therefore, ZENworks Configuration
Management cannot see more than 2 GB of memory. The memory allocated to zenserver and
zenloader, by default, should not be changed; they are already at their optimal configuration for the
32-bit JVM being used.
The default and recommended settings are as follows:
Windows:
Initial Memory Pool: 768
Maximum Memory Pool: 768
Thread Stack Size: 768
Linux:
-Xmx: 1024
-Xms: 1024
-Xss: 1
If the memory allocated to ZENworks Configuration Management memory is increased, Java "out
of memory" errors occur.
