You have two ways to start the real-time statistics service:

• Use the dcsvstart command to start RTSSUP after starting OpenTP1.
• Use the dcsvstart definition command in the user service configuration definition to start RTSSUP.

The real-time statistics service performs the following processing when it starts:

Securing shared memory

The real-time statistics service secures shared memory that the service requires to acquire real-time statistics. If the required shared memory for the real-time statistics service is not secured, the service cancels startup processing. For details about shared memory used by the real-time statistics service, see the manual OpenTP1 Description.

Creating RTS log files

For details about RTS log files, see 3.16.4(2) Outputting real-time statistics to an RTS log file.

Acquiring management information about the real-time statistics service

Use the rtsls command to output the management information about the real-time statistics service that has been acquired to the standard output.

You have two ways to start the extended feature of the real-time statistics service:

• Use the dcsvstart command to start RTSSPP.
• Use the dcsvstart definition command in the user service configuration definition to start RTSSPP.
  When you use the second method to start RTSSPP, write the definition as follows to start RTSSUP and then RTSSPP:
  

  dcsvstart -u RTSSUP dcsvstart -u RTSSPP

If you start the extended feature of the real-time statistics service before you start the real-time statistics service, RTSSPP outputs a KFCA32723-E message to the message log and a KFCA01812-E message with SERVER DOWN as the cause of the error, and goes down. If these messages are displayed, use the dcsvstart command to start RTSSUP (this starts the real-time statistics service) and then restart RTSSPP. The extended feature of the real-time statistics service will start.

Do not apply any of the following commands to the extended feature of the real-time statistics service (RTSSPP). If you do so, an error will occur.

• scdchprc command^#1
• scdhold command^#2
• scdrles command^#1
• scdrsprc command^#1
  

  #1

  RTSSPP goes down.

  #2

  The rtsstats command will not be able to be executed.

To stop the extended feature of the real-time statistics service, use the dcsvstop command to stop RTSSPP.

To stop the real-time statistics service, use the dcsvstop command to stop RTSSUP. If RTSSPP is running, first stop it with the dcsvstop command, and then stop RTSSUP.

To restart the real-time statistics service, start it after it has stopped. When you restart the real-time statistics service, the service recreates RTS log files.

When the real-time statistics service restarts, it starts to acquire real-time statistics. Whether the real-time statistics service inherits the statistics that have been acquired during the previous operation depends on the status of RTSSUP at startup.

Depending on the status of RTSSUP at startup, there are differences in some parts of the operation of the real-time statistics service (whether to inherit previous real-time statistics and the definition of the real-time statistics service to be applied). The following table shows the relationship between the status of RTSSUP at startup and the operation of the real-time statistics service.

Table 3-47 Status of RTSSUP at startup and the operation of the real-time statistics service

Status of RTSSUP at startup		Operation of the real-time statistics service
Startup type	Previous status	Whether previous real-time statistics inherited	Applied definition
Start	Inactive	Not applicable because no real-time statistics have been acquired.	All
Restart	Stopped by the dcsvstop command	Not inherited.	Some
	Forcibly stopped by the dcsvstop command with the -f option	Inherited.	None
	Went down	Inherited.	None
Restart of OpenTP1#	Online	Not inherited.	All
	Forcibly stopped by the dcsvstop command with the -f option	Not inherited.	All

Legend:

All: All the operands and definition commands in the real-time statistics service definition are applied.

Some: All of the real-time statistics service definition except for the following operands is applied:

• rts_service_max operand
• rts_item_max operand

None: None of the operands and definition commands in the real-time statistics service definition are applied.

The real-time statistics service does not start when you use the dcstart command with the -U option specified to restart OpenTP1.
