This chapter describes how to use the cross referencing feature of Oracle SOA Suite to associate identifiers for equivalent entities created in different applications.
This chapter includes the following sections:
Section 46.3, "Creating and Modifying Cross Reference Tables"
Section 46.7, "Creating and Running the Cross Reference Use Case"
Section 46.8, "Creating and Running Cross Reference for 1M Functions"
Cross references enable you to dynamically map values for equivalent entities created in different applications.
Note:
The cross referencing feature enables you to dynamically integrate values between applications, whereas domain value maps enable you to specify values at design time and edit values at runtime. For more information about domain value maps, see Chapter 44, "Working with Domain Value Maps" and Chapter 45, "Using Oracle SOA Composer with Domain Value Maps."When you create or update objects in one application, you may also want to propagate the changes to other applications. For example, when a new customer is created in an SAP application, you may want to create a new entry for the same customer in your Oracle E-Business Suite application named EBS. However, the applications that you are integrating may be using different entities to represent the same information. For example, for each new customer in an SAP application, a new row is inserted in its Customer database with a unique identifier such as SAP_001. When the same information is propagated to an Oracle E-Business Suite application and a Siebel application, the new row should be inserted with different identifiers such as EBS_1001 and SBL001. In such cases, you need some type of functionality to map these identifiers with each other so that they can be interpreted by different applications to be referring to the same entity. This can be done by using cross references.
Cross references are stored in the form of tables. Table 46-1 shows a cross reference table containing information about customer identifiers in different applications.
The identifier mapping is also required when information about a customer is updated in one application and the changes must be propagated to other applications. You can integrate different identifiers by using a common value integration pattern, which maps to all identifiers in a cross reference table. For example, you can add one more column named Common to the cross reference table shown in Table 46-1. The updated cross reference table then appears, as shown in Table 46-2.

Figure 46-1 shows how you can use common value integration patterns to map identifiers in different applications.
Figure 46-1 Common Value Integration Pattern Example
A cross reference table consists of two parts: metadata and actual data. The metadata is saved as the .xref file created in Oracle JDeveloper, and is stored in the Metadata Services (MDS) repository as an XML file. By default, the actual data is stored in the XREF_DATA table of the database in the SOA Infrastructure database schema. You can also generate a custom database table for each cross reference entity. The database table depends on the metadata of the cross reference entity.
Consider the following two cross reference entities:
ORDER with cross reference columns SIEBEL, COMMON, and EBS, as shown in Table 46-3
CUSTOMER with cross reference columns EBS, COMMON, and PORTAL, as shown in Table 46-4
Table 46-3 ORDER Table
| Column Name | SIEBEL | COMMON | EBS |
|---|---|---|---|
|
|
|
|
|
|
|
|
|
If you chose to save all the runtime data in one generic table, then the data is stored in the XREF_DATA table, as shown in Table 46-5.
Table 46-5 XREF_DATA Table
| XREF_TABLE_NAME | XREF_COLUMN_NAME | ROW_NUMBER | VALUE | IS_DELETED |

This approach has the following advantages:
The process of adding, removing, and modifying the columns of the cross reference entities is simple.
The process of creating and deleting cross reference entities from an application is straightforward.
However, this approach has the following disadvantages:
A large number of rows are generated in the database because each cross reference cell is mapped to a different row in the database. This reduces the performance of the queries.
In the generic table, the data for the columns XREF_TABLE_NAME and XREF_COLUMN_NAME is repeated across a large number of rows.
To overcome these problems, you can generate a custom database table for each cross reference entity. The custom database tables depend on the metadata of the cross reference entities. For example, for the XREF_ORDER table and XREF_CUSTOMER table, you can generate the custom database tables shown in Table 46-6 and Table 46-7.
Table 46-6 XREF_ORDER Table
| ROW_ID | SIEBEL | COMMON | EBS |
|---|---|---|---|
|
|
|
|
|
|
|
|
|
This approach requires you to execute Data Definition Language (DDL) scripts to generate the custom database tables. For more information about custom database tables, see Section 46.3.3, "How to Create Custom Database Tables."
You can create cross references tables in a SOA composite application and then use it with a BPEL process service component or an Oracle Mediator service component during transformations.
To create cross reference metadata:
In Oracle JDeveloper, select the SOA project in which you want to create the cross reference.
Right-click the project and select New.
The New Gallery dialog is displayed.
Select SOA Tier from the Categories section, and then select Transformations.
Select Cross Reference(XREF) from the Items section.
Click OK.
The Create Cross Reference(XREF) File dialog is displayed.
In the File Name field, specify the name of the cross reference file. For example, specify Customer.
A cross reference name is used to uniquely identify a cross reference table. Two cross reference tables cannot have same name in the cross reference repository. The cross reference file name is the name of the cross reference table with an extension of .xref.
In the Description field, enter a description for the cross reference. For example:
Cross reference of Customer identifiers.
In the End System fields, enter the end system names.
The end systems map to the cross reference columns in a cross reference table. For example, you can change the first end system name to SAP and the second end system name to EBS. Each end system name must be unique within a cross reference.
A sample Create Cross Reference(XREF) File dialog is displayed in Figure 46-2.
Figure 46-2 Create Cross Reference(XREF) File Dialog
Click OK.
The Cross Reference Editor is displayed, as shown in Figure 46-3. You can use this editor to modify the cross reference.
A file with extension .xref gets created and appears in the Application Navigator. All .xref files are based on the schema definition (XSD) file shown in Example 46-1.
Example 46-1 Cross Reference XSD File
<?xml version="1.0" encoding="UTF-8" ?>

As mentioned previously, all the runtime data by default gets stored in the XREF_DATA table. If you want to create custom database tables, then perform the following steps.
To create custom database tables:
From the Optimize list, select Yes in the Cross Reference Editor.
The name of the custom database table to be generated is displayed in the Table Name field, as shown in Figure 46-4.
Figure 46-4 Generating Custom Database Tables
The Table Name field is editable and you can change the name of the custom table. The custom database table name should be prefixed with xref_. If you do not prefix your table name with xref_, then while generating the table, you receive the following error message:
Table name should begin with 'xref_' and cannot be 'xref_data' or 'xref_deleted_data' which are reserved table names for XREF runtime.
Click Generate Table DDL. The Optimize XREF dialog is displayed.
Select the Generate Drop DDL checkbox to drop the table and associated indexes, if a table with the same name already exists. If you select this option and click Run, then the Running Drop DDL Warning dialog is displayed with the following message:
Running the Drop DDL will remove the table and indexes, do you want to continue?
Click Run. The Run Table DDL dialog is displayed.
From the Connection list, select the database connection to use.
If there is no available connection, then click Create a new database connection to open the Create Database Connection dialog, as shown in Figure 46-5. If you want to edit an existing connection, then select the connection and click Edit selected database connection to open the Edit Database Connection dialog.
Figure 46-5 Create Database Connection Dialog
Enter all the required details and click OK. The Connection list of the Run Table DDL dialog is now populated.
Click OK on the Run Table DDL dialog to run the DDL script.
The Table DDL Run Results dialog displays the execution status of your DDL scripts.
For custom database tables, two additional attributes, namely mode and dbtable, are added to the schema definition mentioned in Section 46.3.2, "What Happens When You Create a Cross Reference." They are added for the table element in the following way:
<attribute name="mode" type="string" default="generic" /> <attribute name="dbtable" type="string" default="xref_data"/>
You can create a cross reference table in a SOA composite application in Oracle JDeveloper and then use it to look up column values at runtime. However, before using a cross reference to look up a particular value, you must populate it at runtime. You can use the cross reference XPath functions to populate the cross-reference tables. The XPath functions enable you to populate a cross reference column, perform lookups, and delete a column value. These XPath functions can be used in the Expression Builder dialog to create an expression or in the XSLT Mapper to create transformations. For example, you can use the xref:populateXRefRow function to populate a cross reference column with a single value and the xref:populateXRefRow1M function to populate a cross reference column with multiple values.
You can access the Expression Builder dialog through an assign activity, an XSL transformation, or the filtering functionality of a BPEL process service component or an Oracle Mediator service component. Figure 46-6 shows how you can select the cross reference functions in the Expression Builder dialog.
Figure 46-6 Expression Builder Dialog with Cross Reference Functions
The XSLT Mapper is displayed when you create an XSL file to transform data from one XML schema to another. Figure 46-7 shows how you can select the cross reference functions in the XSLT Mapper.
Figure 46-7 XSLT Mapper Dialog with Cross Reference Functions
A cross reference table must be populated at runtime before using it. By default, the data is stored in the XREF_DATA table under the SOA Infrastructure database schema. You can use the xref:populateXRefRow function to populate a cross reference column with a single value and the xref:populateXRefRow1M function to populate a cross reference column with multiple values.
Note:
You can also store the data in a different database schema by configuring a data source in the following way:The JNDI name of the data source should be jdbc/xref.
The ORACLE_HOME/rcu/integration/soainfra/sql/xref/createschema_xref_oracle.sql file should be loaded to create the XREF_DATA table in this data source.
The xref:populateXRefRow function populates a cross reference column with a single value. The xref:populateXRefRow function returns a string value, which is the cross reference value being populated. For example, as shown in Table 46-8, the Order table has the following columns: EBS, Common, and SBL with values E100, 100, and SBL_001 respectively.
The syntax of the xref:populateXRefRow function is shown in Example 46-2.
Example 46-2 xref:populateXRefRow Function
xref:populateXRefRow(xrefLocation as string, xrefReferenceColumnName as string, xrefReferenceValue as string, xrefColumnName as string, xrefValue as string, mode as string) as string
xrefLocation: The cross reference table URI.
xrefReferenceColumnName: The name of the reference column.
xrefReferenceValue: The value corresponding to the reference column name.
xrefColumnName: The name of the column to be populated.
xrefValue: The value to be populated in the column.
mode: The mode in which the xref:populateXRefRow function populates the column. You can specify any of the following values: ADD, LINK, or UPDATE. Table 46-9 describes these modes.
Table 46-9 xref:populateXRefRow Function Modes
| Mode | Description | Exception Reasons |
|---|---|---|
|
|
Adds the reference value and the value to be added. For example, the following mode: xref:populateXRefRow("customers.xref"
,"EBS","EBS100", "Common","CM001",
"ADD")
Adds the reference value |
Exceptions can occur for the following reasons:
|
|
|
Adds the cross reference value corresponding to the existing reference value. For example, the following mode: xref:populateXRefRow("customers.xref"
,"Common","CM001","SBL","SBL_
001","LINK")
Links the value |
Exceptions can occur for the following reasons:
|
|
|
Updates the cross reference value corresponding to an existing reference column-value pair. For example, the following mode: xref:populateXRefRow("customers.xref"
,"SBL","SBL_001", "SBL","SBL_
1001","UPDATE")
Updates the value |
Exceptions can occur for the following reasons:

Two values in an end system can correspond to a single value in another system. In such a scenario, you should use the xref:populateXRefRow1M function to populate a cross reference column with a value. For example, as shown in Table 46-11, the SAP_001 and SAP_0011 values refer to one value of the EBS and SBL applications. To populate columns such as SAP, you can use the xref:populateXRefRow1M function.

| SAP | EBS | SBL |
|---|---|---|
|
|
|
|
|
|
|

The syntax of the xref:populateXRefRow1M function is shown in Example 46-3.
Example 46-3 xref:populateXRefRow1M Function
xref:populateXRefRow1M(xrefLocation as string, xrefReferenceColumnName as string, xrefReferenceValue as string, xrefColumnName as string, xrefValue as string, mode as string) as string
xrefLocation: The cross reference URI.
xrefReferenceColumnName: The name of the reference column.

A populated Edit Function – populateXRefRow dialog is shown in Figure 46-9.
Figure 46-9 Populated Edit Function – populateXRefRow Dialog
After populating the cross reference table, you can use it to look up a value. The xref:lookupXRef and xref:lookupXRef1M functions enable you to look up a cross reference for single and multiple values, respectively.
You can use the xref:lookupXRef function to look up a cross reference column for a value that corresponds to a value in a reference column. For example, the following function looks up the Common column of the cross reference tables described in Table 46-2 for a value corresponding to the SAP_001 value in the SAP column.
xref:lookupXRef("customers.xref","SAP","SAP_001","Common",true())
The syntax of the xref:lookupXRef function is shown in Example 46-4.
Example 46-4 xref:lookupXRef Function
xref:lookupXRef(xrefLocation as string, xrefReferenceColumnName as string, xrefReferenceValue as string, xrefColumnName as string, needAnException as boolean) as string
xrefLocation: The cross reference URI.
xrefReferenceColumnName: The name of the reference column.
xrefReferenceValue: The value corresponding to the reference column name.
xrefColumnName: The name of the column to be looked up for the value.
needAnException: When the value is set to true, an exception is thrown if the value is not found. Otherwise, an empty value is returned.
At runtime, an exception can occur for the following reasons:
The cross reference table with the given name is not found.
The specified column names are not found.
The specified reference value is empty.
Multiple values are found.
You can use the xref:lookupXRef1M function to look up a cross reference column for multiple values corresponding to a value in a reference column. The xref:lookupXRef1M function returns a node-set containing multiple nodes. Each node in the node-set contains a value.
For example, the following function looks up the SAP column of Table 46-11 for multiple values corresponding to the EBS_1001 value in the EBS column:
xref:lookupXRef1M("customers.xref","EBS","EBS_1001","SAP",true())
The syntax of the xref:lookupXRefRow1M function is shown in Example 46-5.
Example 46-5 xref:lookupXRefRow1M Function
xref:lookupXRef1M(xrefLocation as String, xrefReferenceColumnName as String, xrefReferenceValue as String, xrefColumnName as String, needAnException as boolean) as node-set
xrefLocation: The cross reference URI.
xrefReferenceColumnName: The name of the reference column.
xrefReferenceValue: The value corresponding to the reference column name.
xrefColumnName: The name of the column to be looked up for the value.
needAnException: If this value is set to true, an exception is thrown when the referenced value is not found. Otherwise, an empty node-set is returned.
Example of the xref:lookupXRefRow1M Function
Consider the Order table shown in Table 46-14 with the following three columns: Siebel, Billing1, and Billing2.
For 1:1 mapping, the xref:lookupPopulatedColumns("Order","Siebel","100","false") method returns the values shown in Example 46-6.
Example 46-6 xref:lookupPopulatedColumns Method
<column name="BILLING1">101</column> <column name="BILLING2">102</column>
In this case, both the columns, Billing1 and Billing2, are populated.
For 1:M mapping, the xref:lookupPopulatedColumns("Order","Siebel","110","false") method returns the values shown in Example 46-7.
Example 46-7 xref:lookupPopulatedColumns
<column name="BILLING2">111</column> <column name="BILLING2">112</column>
In this case, Billing1 is not populated.
An exception can occur for the following reasons:
The cross reference table with the given name is not found.
The specified column names are not found.
The specified reference value is empty.
You can use the xref:lookupPopulatedColumns function to look up all the populated columns for a given cross reference table, a cross reference column, and a value. The xref:lookupPopulatedColumns function returns a node-set with each node containing a column name and the corresponding value.
The syntax of the xref:LookupPopulatedColumns function is shown in Example 46-8.
Example 46-8 xref:LookupPopulatedColumns Function
xref:LookupPopulatedColumns(xrefTableName as String,xrefColumnName as String,xrefValue as String,needAnException as boolean)as node-set
xrefTableName: The name of the reference table.
xrefColumnName: The name of the reference column.
xrefValue: The value corresponding to the reference column name.
needAnException: If this value is set to true, then an exception is thrown when no value is found in the referenced column. Otherwise, an empty node-set is returned.
An exception can occur for the following reasons:
The cross reference table with the given name is not found.
The specified column names are not found.
The specified reference value is empty.
To look up a cross reference table column:
In the XSLT Mapper, expand the trees in the Source and Target panes.
Drag and drop the source element to the target element.
In the Component Palette, select Advanced.
Select XREF Functions.
Drag and drop the lookupXRef function to the line that connects the source object to the target object.
A lookupXRef icon appears on the connecting line.
Double-click the lookupXRef icon.
The Edit Function – lookupXRef dialog is displayed, as shown in Figure 46-10.

Click OK.
A populated Edit Function – lookupXRef dialog is shown in Figure 46-11.
Figure 46-11 Populated Edit Function – lookupXRef Dialog
You can use the xref:markForDelete function to delete a value in a cross reference table. The value in the column is marked as deleted. This function returns true if the deletion is successful. Otherwise, it returns false.
Any column value marked for deletion is treated as if the value does not exist. Therefore, you can populate the same column with the xref:populateXRefRow function in ADD mode.
Note:
Using a column value marked for deletion as a reference value inLINK mode of the xref:populateXRefRow function raises an error.A cross reference table row should have at least two mappings. If you have only two mappings in a row and you mark one value for deletion, then the value in another column is also deleted.
The syntax for the xref:markForDelete function is shown in Example 46-9.
Example 46-9 xref:markForDelete Function
xref:markForDelete(xrefTableName as string, xrefColumnName as string, xrefValueToDelete as string) return as boolean
xrefTableName: The cross reference table name.
xrefColumnName: The name of the column from which you want to delete a value.
xrefValueToDelete: The value to be deleted.
An exception can occur for the following reasons:
The cross reference table with the given name is not found.
The specified column name is not found.
The specified value is empty.
The specified value is not found in the column.
Multiple values are found.
To delete a cross reference table value:
In the XSLT Mapper, expand the trees in the Source and Target panes.
Drag and drop the source element to the target element.
In the Component Palette, select Advanced.

This cross reference use case implements an integration scenario between Oracle EBS, SAP, and Siebel instances. In this use case, when an insert, update, or delete operation is performed on the SAP_01 table, the corresponding data is inserted or updated in the EBS and SBL tables. Figure 46-14 provides an overview of this use case.

For downloading the sample files mentioned in this section, visit the following URL:
https://soasamples.samplecode.oracle.com/#mediator
This section provides the design-time tasks for creating, building, and deploying your SOA Composite application. These tasks should be performed in the order in which they are presented.
To configure the Oracle database and database adapter:
You need the SCOTT database account with password TIGER for this use case. You must ensure that the SCOTT account is unlocked.
You can log in as SYSDBA and then run the setup_user.sql script available in the XrefOrderApp1M/sql directory to unlock the account.
Run the create_schema.sql script available in the XrefOrderApp1M/sql directory to create the tables required for this use case.
Run the create_app_procedure.sql script available in the XrefOrderApp1M/sql directory to create a procedure that simulates the various applications participating in this integration.
Run the createschema_xref_oracle.sql script available in the OH/rcu/integration/soainfra/sql/xref/ directory to create a cross reference table to store runtime cross reference data.
Copy the ra.xml and weblogic-ra.xml files from $BEAHOME/META-INF to the newly created directory called META-INF on your computer.
Edit the weblogic-ra.xml file available in the $BEAHOME/META-INF directory as follows:
Modify the property to xADataSourceName as follows:
<property> <name>xADataSourceName</name> <value>jdbc/DBConnection1</value> </property>
Modify the jndi-name as follows:

An application server connection is required for deploying your SOA composite application. For information on creating an application server connection, see Section 41.7.1.1.1, "Creating an Application Server Connection."
Deploying the XrefCustApp composite application consists of the following steps:
Creating an application deployment profile
Deploying the application to the application server
For detailed information about these steps, see Section 41.7.1, "Deploying a Single SOA Composite in Oracle JDeveloper."
After deploying the XrefCustApp application, you can run it by using any command from the insert_sap_record.sql file present in the XrefCustApp/sql folder. On successful completion, the records are inserted or updated in the EBS and SBL tables and the Logger reference writes the output to the output.xml file.
For monitoring the running instance, you can use the Oracle Enterprise Manager Fusion Middleware Control at the following URL:
http://hostname:port_number/em
where hostname is the host on which you installed the Oracle SOA Suite infrastructure and port_number is the port running the service.
The cross reference use case implements an integration scenario between two end-system Oracle EBS and SAP instances. In this use case, the order passes from SAP to EBS. SAP represents the orders with a unique ID, whereas EBS splits the order into two orders: ID1 and ID2. This scenario is created using database adapters. When you poll the SAP table for updated or created records, an SAP instance is created. In EBS, the instance is simulated by a procedure and the table is populated. Figure 46-46 provides an overview of this use case.
Figure 46-46 XrefOrderApp Use Case in SOA Composite Editor
For downloading the sample files mentioned in this section, visit the following URL:

This section provides the design-time tasks for creating, building, and deploying your SOA composite application. These tasks should be performed in the order in which they are presented.
To configure the Oracle database and database adapter:
You need the SCOTT database account with password TIGER for this use case. You must ensure that the SCOTT account is unlocked.
You can log in as SYSDBA and then run the setup_user.sql script available in the XrefOrderApp1M/sql folder to unlock the account.
Run the create_schema.sql script available in the XrefOrderApp1M/sql folder to create the tables required for this use case.
Run the create_app_procedure.sql script available in the XrefOrderApp1M/sql folder to create a procedure that simulates the various applications participating in this integration.
Run the createschema_xref_oracle.sql script available in the Oracle_Home/rcu/integration/soainfra/sql/xref/ folder to create a cross reference table to store runtime cross reference data.
Copy the ra.xml and weblogic-ra.xml files from $BEAHOME/META-INF to the newly created directory called META-INF on your computer.
Edit the weblogic-ra.xml file, which is available in the $BEAHOME/src/oracle/tip/adapter/db/test/deploy/weblogic/META-INF folder for your SOA application, as follows:
Modify the property to xADataSourceName as follows:
<property> <name>xADataSourceName</name> <value>jdbc/DBConnection1</value> </property>
Modify the jndi-name as follows:
<jndi-name> eis/DB/DBConnection1</jndi-name>
This sample uses eis/DB/DBConnection1 to poll the SAP table for new messages and to connect to the procedure that simulates Oracle EBS and Siebel instances.
Package the ra.xml and weblogic-ra.xml files as a RAR file and deploy the RAR file by using Oracle WebLogic Server Administration Console.
Create a data source using the Oracle WebLogic Server Administration Console with the following values:
jndi-name=jdbc/DBConnection1
user=scott
password=tiger
url=jdbc:oracle:thin:@host:port:service
connection-factory factory-class=oracle.jdbc.pool.OracleDataSource
