2.5.2 Setup of execution environment in load balance cluster configuration

After setting up the environment, set up the execution environment configuring the load balance cluster.

The following figure shows the flow of execution environment setup in load balance cluster configuration:

Figure 2‒6: Flow of setup in load balance cluster configuration

Steps 1 to 5 given in the figure are described here:

For details on operations in load balance cluster configuration, see "5.7.1 Operations in the load-balancing cluster configuration".

Organization of this subsection

(1) Preparing setup
(2) Execution environment setup
(3) Setting a load balancer
(4) Starting standard reception
(5) Connecting a load balancer

(1) Preparing setup

Perform the following operations before setup. Perform the following operations in all HCSC servers configuring the load balance cluster:

Setting software required in the execution environment

Perform J2EE server setup. For details on setting contents and how to set, see "3.1.2 Setting up the software required for the execution environment".

A unique name must be set in each HCSC server in the load balance cluster for Reliable Messaging system name.

Settings when using CTM

Set true in request-ejb.ctm in HCSC server runtime definition file while using CTM.

For details on HCSC server runtime definition file, see "6.5.6 HCSC server runtime definition file" in "Service Platform Reference Guide".

Sending control in the service requester

Disconnect the network for the service requester and change to the status in which HCSC server does not receive the service component execution request.

(2) Execution environment setup

The following table describes execution environment setup procedure:

Start the process in the following order:

Start order	Process to be started	Start method
1	Administration Agent	See "Application Server System Setup and Operation Guide".
2	Management Server
3	PRF
4	Smart Agent
5	CTM domain manager (if CTM is used)
6	CORBA naming service (if CORBA naming service is used)
7	CTM daemon (if CTM is used)
8	J2EE server
9	HTTP Server (if HTTP Server is used)	See "5.3.5 Starting HTTP Server".

Set up HCSC server.

For details on how to set up HCSC server, see "3.1.3 Setting up an HCSC server".
Start HCSC server.

For details on how to start HCSC server, see "5.3.4 Starting HCSC server".
Deploy service adapter and business process.

For details on how to deploy the service adapter and business process, see "3.1.8 Deploying a service adapter" and "3.1.13 Deploying a business process".
Start service adapter and business process.

For details on how to start the service adapter and business process, see "5.3.6 Starting Service Adapters" and "5.3.7 Starting Business Processes".

(3) Setting a load balancer

Set to send the service product execution request to all HCSC servers configuring the load balance cluster.

The same value must be set in CTM domain manager name and smart agent port number in all HCSC servers while using CTM.

For details on how to set up the load balancer, see the used load balancer document.

(4) Starting standard reception

Start standard reception of all HCSC servers. For details on how to start the standard reception, see "5.3.9 Starting standard receptions".

(5) Connecting a load balancer

Connect the load balancer and change it to usable status.

These procedures are unnecessary while using CTM.

For details on how to start connection of the load balancer, see the used load balancer document.
