Appendix B.1 JP1/IM processes (Windows)

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

Organization of this subsection

(1) JP1/IM - Manager

(2) JP1/IM - View

(1) JP1/IM - Manager

The table below describes the JP1/IM - Manager processes. The numbers in parentheses are the number of processes that can be executed concurrently.

Table B-1 JP1/IM - Manager processes (Windows)

Parent process	Functionality	Child process	Functionality
jco_spmd.exe (1)	JP1/IM - Manager process management	jcamain.exe (1)	Automatic Action Service (displayed process name: jcamain)
		evtcon.exe (1)	Event console service (displayed process name: evtcon)
		evflow.exe (1)	Event base service (displayed process name: evflow)
		jcsmain.exe (1)	Central Scope service (displayed process name: jcsmain)
		evgen.exe (2)#1	Correlation event generation service#2 (displayed process name: evgen)
		jcfmain.exe(1)	IM Configuration Management service (displayed process name: jcfmain)
jco_service.exe(1)	Windows service control in JP1/IM - Manager	--	--
pdservice.exe	IM database	--	Windows service control
		pdprcd.exe	Process server process
pdprcd.exe(1)	IM database	--	Process server process
		pdrsvre.exe(3)	Post-processing process. Performs recovery processing when a process terminates abnormally.
		pdmlgd.exe(1)	Message log server process. Controls message output.
		pdrdmd.exe(1)	System manager process. Controls unit starting and stopping and manages connected users.
		pdstsd.exe(1)	Status server process. Controls I/O operations to unit status files.
		pdscdd.exe(1)	Scheduler process. Distributes transactions among single server processes.
		pdtrnd.exe(1)	Transaction server process. Controls transactions.
		pdtrnrvd.exe(1 to 128)#3	Transaction recovery process. Controls transaction determination and recovery.
		pdlogd.exe(1)	Log server process. Controls acquisition of system logs and log-related processes.
		pd_buf_dfw.exe(1)	Deferred write process. Controls background writing to disks where the database is kept.
		pdlogswd.exe(1)	Log swapper process. Allocates and de-allocates system log-related files, manages I/O operations for system log-related files, and acquires syncpoint dumps.
		pdsds.exe(10 to 128)#4	Single server process. Performs SQL processing.
pdsha.exe (1)	IM database	--	Service for embedded HiRDB in a cluster environment

Legend:

--: None

#1: 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.

#2: 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.

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

#4: 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 32.

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

The table below describes JP1/IM - View processes. The numbers in parentheses are the number of processes that can be executed concurrently.

Table B-2 JP1/IM - View processes

Parent process	Functionality	Child process	Functionality
jcoview.exe (3 + 3#)	JP1/IM - View process management	jcoview_evt.exe (3)	Sends thread dump output events
		java.exe (3 + 3#)	JP1/IM - View window control
jcfview.exe (3)	JP1/IM - IM Configuration Management - View process management	jcfview_evt.exe (3)	Sends thread dump output events
		java.exe (3 + 3#)	JP1/IM - IM Configuration Management - View window control

#: Add when the JP1/IM - View (JP1/IM - Rule Operation linkage function) is active.
