Configuring the Resource Manager
As explained in Chapter 4, XA connections to your database are established by using the database() function in RWDBManager, and providing its propertyString parameter with key XA=xaParameter. This section explains how you obtain the value of the xaParameter argument that is specific to Oracle OCI.
The value of the xaParameter argument must be the same as that used for the DB parameter in the open string passed to the TPM to open the database. For example, the open string for the Oracle databases takes the following form:
 
Oracle_XA(+required_fields) [+optional_fields]
NOTE: For complete and accurate connection information, consult the documentation for your database and TPM.
As of this printing, required_fields are:
*User and password: Acc=P/user/password
*Session time limit: SesTm=session_time_limit
The optional_fields includes:
*Database name: DB=db_name
Note that the value of this DB parameter is the same value that you provide in the argument XA=xaParameter when defining the propertyString parameter in RWDBManager::database(). See RWDBDatabase Objects.
