4.6.7 Defining a physical tier
(1) <tier>
- Contents
- You must define this tag.
- Defines the physical tier.
- There are six types of physical tiers; combined-tier, http-tier, j2ee-tier, sfo-tier, ctm-tier and free-tier. These physical tiers, single or combination of multiple tiers configure a Web system.
- The specifiable physical tier configurations are as follows:
- combined-tier configuration
- http-tier and j2ee-tier configuration#1
- http-tier configuration #2
- j2ee-tier configuration
- Configuration in which the sfo-tier is combined with the combined-tier#1
- Configuration in which the sfo-tier is combined with the http-tier and j2ee-tier#1
- ctm-tier configuration
- free-tier configuration#1
- #1 You can use this configuration in a system set up with the Smart Composer functionality. You cannot use this configuration with a virtual system.
- #2 You can use this configuration in a virtual system. You cannot use this configuration with a system set up with the Smart Composer functionality.
- In the combined-tier configuration
- Configure the Web server and J2EE server included in the service unit on one host, and define them in one <tier> tag.
- In the http-tier and j2ee-tier configuration
- Configure the Web server and J2EE server included in the service unit on different hosts, and define them in two <tier> tags.
- In the http-tier configuration
- Configure the Web server included in a service unit on one host and define the server in one <tier> tag. To use the http-tier configuration, you must prepare the virtual server of the j2ee-tier configuration associated with the virtual server group information file.
- In the j2ee-tier configuration
- Configure the J2EE server included in the service unit on one host, and define in one <tier> tag. When using the j2ee-tier configuration, the in-process HTTP server functionality must be enabled. To use the j2ee-tier configuration in a virtual system, you must prepare the virtual server of the combined-tier configuration associated with the virtual server group information file.
- For sfo-tier to be configured with the combination of combined-tier or http-tier and j2ee-tier
- Configure the session failover server (SFO server) included in the service unit on one host, and define in one <tier> tag.
- In the ctm-tier configuration
- The ctm-tier defines tags in a Web system different from the Web system defining the combined-tier, http-tier, j2ee-tier, and sfo-tier. For the ctm-tier configuration, configure the CTM-related logical server included in a service unit (CTM domain manager, CTM, and Smart Agent) and a J2EE server on one host, and define the servers in one <tier> tag.
- Also, to allocate an integrated naming scheduler server, define the Web system separately for the integrated naming scheduler server and for the CTM.
- The Web system for the integrated naming scheduler server configures the CTM-related logical server included in a service unit (CTM domain manager, CTM, and Smart Agent) on one host and defines the server in one <tier> tag.
- To use the ctm-tier configuration in a virtual system, you must prepare the virtual server belonging to the management units of the combined-tier configuration in addition to the virtual server belonging to the management units of the ctm-tier configuration.
- In the free-tier configuration
- A configuration that does not match the definition of any other physical tier is defined as 1 tier tag.

(2) <tier-type>
- Contents
- You must define this tag.
- Specifies the types of physical tiers. The types of physical tiers are as follows:
- combined-tier
- http-tier
- j2ee-tier
- sfo-tier
- ctm-tier
- free-tier
- Specifiable value
- The following strings can be specified:
- combined-tier
- http-tier
- j2ee-tier
- sfo-tier
- ctm-tier
- free-tier
- Omitting tags
- Cannot be omitted.
- Omitting values
- Cannot be omitted.
(3) <j2ee-server-count>
- Contents
- Specifies the number of J2EE servers to be deployed on one host, when ctm-tier is specified in the <tier-type> tag, as an integer in the range from 0 to 32.
- Specifiable value
- Specify the value using an integer from 0 to 32.
- In the Web system for the integrated naming scheduler server
- Specify 0.
- Web system for CTM
- Specifies the number of J2EE servers to be deployed in one host for each Web system.
- Note that when the configuration of the Web system is changed, the number of J2EE servers cannot be changed.
- Omitting tags
- Can be omitted.
- Omitting values
- Can be omitted.
(4) <configuration>
- Contents
- Defines the configuration to be applied to all the logical servers in the physical tier for each type of logical server.
- For example, to define two configurations, such as Web server and J2EE server, use two <configuration> tags for definition, one for defining the Web server and the other for defining the J2EE server.
- Specifiable value
- --
- Omitting tags
- Can be omitted.
- Omitting values
- Can be omitted.
(5) <logical-server-type>
- Contents
- You must define this tag.
- Specifies the types of logical servers for defining the configuration. The types of logical server are as follows:
- web-server:Web server
- j2ee-server:J2EE server
- sfo-server:Session failover server (SFO server)
- performance-tracer:Performance tracer
- ctm-domain-manager:CTM domain manager
- component-transaction-monitor:CTM
- smart-agent:Smart Agent
- The logical server that can define the configuration varies according to the physical tier type. The types of physical tiers are as follows:
- In combined-tier
- Web server, J2EE server, and performance tracer
- In http-tier
- Web server and performance tracer
- In j2ee-tier
- J2EE server and performance tracer
- In sfo-tier
- Session failover server (SFO server) and performance tracer
- In ctm-tier
- The logical servers that can be defined are different for each Web system.
- In the Web system for the integrated naming scheduler server
CTM domain manager, CTM, Smart Agent, and the performance tracer
- Web system for CTM
CTM domain manager, CTM, Smart Agent, J2EE server, and performance tracer
- Note:
- In a physical tier definition, you cannot specify the logical server configuration included in the user server and free-tier configuration. Specify these logical server configurations using unit definitions.
- Specifiable value

- web-server
- j2ee-server

- Specifies the number for identifying the J2EE server when a common configuration is specified for specific J2EE servers within the physical tier.
- The specifiable range is from 1 to the value specified in <j2ee-server-count>. Specify a unique number in the physical tier.
- You can only specify this tag when ctm-tier is specified in the <tier-type> tag, and when the <j2ee-server-count> tag is specified.
- This tag must not be specified if a common configuration is to be specified for all the J2EE servers within the physical tier.
