8.4.9 JP1/Base process management

Process management is a core functionality of JP1/Base that starts and stops the processes that make up JP1/Base. Another responsibility of process management is to issue instructions for checking the status of JP1/Base functions and reloading definition information.

JP1/Base process management controls the following functions:

The event service, event converters, and Hitachi Network Objectplaza Trace Library (HNTRLib2) operate independently of the process management functionality. For details, see the JP1/Base User's Guide.

Process management is realized by the following commands:

Table 8‒13: Process management commands

Functionality

Command

Description

Start JP1/Base

(internal command)

jbs_spmd

(For UNIX only)

Internal commands used to start and stop JP1/Base processes.

These commands apply to the processes managed by process management.

Do not execute these commands directly to start or stop JP1/Base process management. In Windows, JP1/Base process management is started and stopped by the Windows service control manager. In UNIX, use the start and stop commands (jbs_start and jbs_stop).

Stop JP1/Base

(internal command)

jbs_spmd_stop

JP1/Base status check

jbs_spmd_status

Checks the activity status of the processes managed by process management.

Reload JP1/Base definition information

jbs_spmd_reload

When definition information is updated for a process managed by process management, this command reloads and applies the new definitions.

Process management also provides the following functionality to help detect and deal with errors in JP1/Base.

This functionality applies to the processes under the control of process management, and is supported from JP1/Base version 07-00.

Important

If you are using JP1/Base in a cluster system, do not set up process management to restart processes at abnormal termination, as the error in the JP1/Base process might also affect the function that restarts processes. To ensure a more reliable restart, restart JP1 under the control of the clustering software.

For details about the commands in the table and how to deal with process management errors, see the description of the settings for dealing with JP1/Base errors in the chapter on installation and setup in the JP1/Base User's Guide.
