Existence of usage of the database and Reliable Messaging differs according to the functionality of Service Platform to be used and the kind of operation required. The following table describes the existence of usage of Reliable Messaging and database as per each functionality:

Table 2-2 TableDatabase of each functionality to be used and existence of usage of Reliable Messaging

Functionality to be used		Database	Reliable Messaging
Synchronous reception is to be used		N	N
Asynchronous reception (standard reception (MDB(WS-R)), standard reception (MDB(DB queue))) are to be used		N	N
Synchronous service adapter is to be used		N	N
Asynchronous service adapter (MDB(WS-R) adapter, MDB(DB queue) adapter) are to be used		Y	Y
Business process is to be used	Persistent business process is to be used	Y	N
	Non-persistent business process is to be used#1	N	N
Process instance execution history is to be managed		Y	N
DB adapter is to be used		N#2	N

(Legend)

Y: Mandatory.

N: Not mandatory.

Note #1

Please note that when a non-persistent business process is used, there are restrictions in the processes that can be defined in the start environment. For details, see "3.3 Business processes that are to be made persistent and that are not to be made persistent" in "Service Platform Overview".

Note #2

When you use DB adapter, a database is not required in a machine on which HCSC server is running. However, database is required on a service running machine connected from DB adapter.

From the above table it is understood that the configuration format according to existence of usage of the database and Reliable Messaging contains the following 3 patterns:

• Both database and Reliable Messaging are used
• Both database and Reliable Messaging are not used
• Database is used and Reliable Messaging is not used

Contents of settings related to the execution environment are different during system setup according to each pattern. For details on execution environment setting contents in each pattern, see "2.3 Settings related to execution environment".

Setting of existence of usage of the database and Reliable Messaging is defined in HCSC server setup definition file. Database settings are not required if the database is not used and Reliable Messaging setting is not required if Reliable Messaging is not used.

Note

Provide appropriate access permission to the following directories and files to be accessed in the execution environment or operating environment:

• Service Platform installation directory
• Directories and files specified by the command argument
• Directories and files specified in all types of definition files used in HCSC
