Note that the FREEZE command precedes the STOP and ALTER commands; and also note that the THAW command must precede the START
command.
Managing the Distributed Object Environment
This subsection provides an overview of the tasks involved with managing the NonStop CORBA distributed object environment. The NonStop
CORBA system implements the ORB on the NonStop Kernel operating system. Managing this environment includes monitoring the system
processes contained in the NonStop CORBA system, monitoring the underlying networking resources, tuning the system configuration for
performance, and troubleshooting the ORB.
The Distributed Object Environment
The figure below shows some of the major components of the NonStop CORBA system runtime environment and the tools you use to manage
each type of component.
NonStop CORBA Configuration Management
The NonStop CORBA system is implemented as an application using TS/MP, which provides for scalability and load balancing by allowing
multiple processes to work in parallel to perform the same task. TS/MP also provides for availability: its monitor process, called PATHMON,
automatically restarts a process that fails. Because TS/MP provides all process management for the NonStop CORBA system, you use TS/MP
interfaces to configure and manage the NonStop CORBA system processes.
The user interface of TS/MP is a line-oriented utility called PATHCOM. PATHCOM includes commands for setting and reviewing configuration
options, starting and stopping processes, and gathering information about process status and utilization. You can use PATHCOM interactively
or by means of command files. You can also write applications that use the Subsystem Programmatic Interface (SPI) to perform any function
available through PATHCOM.
To define and maintain the configuration of networking resources, such as TCP/IP, you use the Subsystem Control Facility (SCF) or write an
application that uses the SPI. The SCF and corresponding programmatic interfaces include commands for setting and reviewing configuration
options and for gathering information about the status and use of communication lines, processes, and related resources.
NonStop CORBA Performance Tuning
Performance tuning of the runtime environment of the NonStop CORBA system is primarily a matter of deciding on the number and relationships
