4.2.2 System configuration of a system that uses the scheduling functionality of batch applications

This subsection describes the system configuration that uses the scheduling functionality of the batch applications, for using a batch server.

Organization of this subsection

(1) Features of system configuration
(2) Processes and software required on each machine

(1) Features of system configuration

This is a system configuration for using a batch server and CTM. In this case, the batch server and CTM are deployed on the Application Server. The batch server and CTM is built and operated as a Web system (ctm-tier) of the Smart Composer functionality. You use batch execution commands for executing batch applications. A batch application executed by directly by command is scheduled using a CTM, and then distributed to the batch servers.

The following figure shows an example of the system configuration for using a CTM. In this example, two batch servers are deployed and the execution request of the batch application is scheduled using a CTM.

Figure 4‒4: Example of system configuration for using CTM

For other legend items, see 3.2 Description of the system configuration.

Features: You can execute multiple batch execution commands concurrently by scheduling the execution requests of a batch application using a CTM. Moreover, you must not use batch execution commands for specifying a batch server.
Flow of the process: A batch application executed by directly by the batch execution command is registered as an execution request of the batch application in the schedule queue of CTM. The execution request of the batch application in the schedule queue is distributed to an appropriate batch server using CTM. Note that the execution request of the batch application is retained (standby) in the schedule queue when the batch server, where the execution request is to be distributed, does not exist.

(2) Processes and software required on each machine

The software and processes required on each machine are as follows:

(a) Application server machine

You must install Application Server on an Application Server machine. Note that for the development environment, you must install Developer.

The following processes are to be started:

Batch server
PRF daemon
Global CORBA Naming Service
Group of CTM processes (CTM daemons and CTM regulators)
CTM domain manager
Smart Agent
Management Server
Administration Agent

When connecting to the database, you also require the software for connecting to the database to be used. For details about the products required for connecting to the database, see 3.6.1 Configuration when using a local transaction. However, you can use only the following databases as resources in a batch server:

HiRDB
Oracle
SQL Server
XDM/RD E2

(b) Database server machine

For details about the products required in a database server machine, see the description about the machine on which the resource manager operates, in the subsection 3.6.1 Configuration when using a local transaction. However, you can use only the following databases as resources in a batch server:

HiRDB
Oracle
SQL Server
XDM/RD E2
