The following shows the process names displayed in the Processes page of the Windows Task Manager.

Organization of this subsection

(1) JP1/IM - Manager

IM database

--

Service for embedded HiRDB in a cluster environment

Legend:

--: None

#1: The process is started only when Central Scope is used. The process is not started by default.

#2: Maximum 2; normally 1. Breakdown as follows:

  • Main processes of the event generation service

  • Temporary process issued when the event service is connected. The process is generated when the event generation service starts and when an event acquisition filter is updated.

#3: Functionality for correlation event issue (inactive by default). The correlation event generation service is used in systems that do not use the integrated monitoring database.

#4: The process is started when IM Configuration Management is used. The process is not started by default.

#5: The process is started when the Intelligent Integrated Management Base is used. The process is not started by default.

#6: When the parent process starts, no child process is started. The number of child processes increases with the number of remotely monitored files. The maximum number of concurrent child processes is 157.

#7: Only one process runs when the system starts, but this number increases temporarily with each abnormal termination of the pdsds.exe process.

#8: 10 instances of this process run at startup, and this number increases with the number of access requests to the IM database. The maximum number of concurrent processes is 96.

When JP1/IM - Manager is used in a cluster system, the above processes are executed on each physical host and logical host. The number of processes that can be executed concurrently is the number of processes in the table multiplied by the number of physical and logical hosts on which the processes are running.

Processes in the above table whose parent process is jco_spmd.exe are controlled by the process management. You can check their status using the jco_spmd_status command.

An example of the display when the processes are running normally is shown below.

c:\>jco_spmd_status

KAVB3690-I Processing to report the status of JP1_CONS has started.

Display the running processes

Process name Process ID

evflow 3672

jcamain 4088

evtcon 4236

jcsmain 4668

evgen 5624

KAVB3691-I All the processes have started.

jcsmain is listed only when the Central Scope functionality is enabled, evgen is listed only when correlation event generation is enabled, and jcfmain is listed only when the IM Configuration Management functionality is enabled.

(2) JP1/IM - View

Important
  • In case of operating in Japanese if the program jcoview.exe is executed from a command prompt where the code page is set to a value other than 932, the characters displayed on the screen might be garbled.

  • In case of operating in Chinese if the program jcoview.exe is executed from a command prompt where the code page is set to a value other than 936, the characters displayed on the screen might be garbled.
