CAUTION: When you run the VxWorks target-based tools, avoid concurrent use of the corresponding tools that execute on the host. There is no technical restriction forbidding this, but an environment with--for example--two shells, each with its own symbol table, can be quite confusing. Most users choose either host-based tools or target-based tools, and seldom switch back and forth

In addition to the standard VxWorks offering, Tornado is compatible with the features provided by the optional component VxVMI. VxVMI provides the ability to make text segments and the exception vector table read-only, and includes a set of routines for developers to build their own virtual memory managers. When VxVMI is in use, Tornado's target-server loader/unloader takes account of issues such as page alignment and protection.

Tornado is also compatible with the VxWorks optional component VxMP. VxMP provides shared semaphores for synchronization of tasks on different CPUs, as well as shared message queues and shared memory management.

For detailed information on VxWorks and on its optional components, see the VxWorks Programmer's Guide and the VxWorks Network Programmer's Guide.
