2 Installation and Configuration

This chapter describes how to install and configure the OA adapter. It contains the following topics:

• Installing the OA Adapter

• Installing Multiple OA Adapters in the Same Oracle Home

• Configuring the OA Adapter

Installing the OA Adapter

The OA adapter must be installed in an existing Oracle home Middle Tier for Oracle Application Server Integration InterConnect 10g Release 2 (10.1.2).

This section contains the following topics:

• Preinstallation Tasks

• Installation Tasks

Preinstallation Tasks

Refer to the following guides before installing the OA adapter:

• Oracle Application Server Installation Guide for information about OUI startup.

• Oracle Application Server InterConnect Installation Guide, for information about software, hardware, and system requirements for OracleAS Integration InterConnect.

  
  

  Note: OracleAS Integration InterConnect hub is installable through the OracleAS Integration InterConnect hub installation type. You must install the OracleAS Integration InterConnect hub before proceeding with the OA adapter installation.

  
  

Installation Tasks

To install the OA adapter:

1. On the Available Product Components screen of the OracleAS Integration InterConnect installation Wizard, select OracleAS Integration InterConnect Adapter for Oracle Applications 10.1.2.0.2 and click Next.

2. The Set Oracle Wallet Password screen is displayed. Enter and confirm the password on the screen, which will be used to manage OracleAS Integration InterConnect installation. Click Next.

   • Go to step 3 if installing the OA adapter in an OracleAS Middle Tier Oracle home that does not have an InterConnect component already installed. Ensure that the OracleAS Integration InterConnect hub has been installed.

   • Go to step 4 if installing the OA adapter in an OracleAS Middle Tier Oracle home that has an existing InterConnect component. Ensure that it is a home directory to an OracleAS Integration InterConnect component.

3. The Specify Hub Database Connection screen is displayed. Enter information in the following fields:

   • Host Name: The host name of the computer where the hub database is installed.

   • Port Number: The TNS listener port for the hub database.

   • Database SID: The SID for the hub database.

   • Password: The password for the hub database user.

4. Click Next. The Specify Oracle Applications Adapter Name screen is displayed.

5. Enter the application name. Blank spaces are not permitted. The default value is myOracleAppsAdapter.

   
   

   Note: You can change the application name in iStudio after installation. In such a case, you need to specify the password corresponding to new application name in the Oracle Wallet. For more informtion, refer to the following sections in Appendix A, "Frequently Asked Questions": AppendixA, "My OA adapter is not starting. What could be the reason?" AppendixA, "How do I secure my passwords?"

   
   

6. Click Next. The Specify Spoke Application Database Connection screen is displayed. This configures the information to the spoke application database. Enter information in the following fields:

   • Host Name: The name of the computer where the application database is installed.

   • Port Number: The TNS listener port for the application database.

   • Database SID: The SID for the application database.

   • Sys Password: The password of the sys user in the spoke database.

   The information on this screen is for Oracle Applications, from which the adapter will deliver or receive messages.

7. Click Next. The Specify APPS Schema Password screen is displayed. Enter the password for the schema name in Password field.

8. Click Next. The Set Bridge Schema Password screen is displayed.

9. Enter and confirm the password for the bridge schema.

10. Click Next. The Summary screen is displayed.

11. Click Install to install the OA adapter and other selected components. The OA adapter is installed in the following directory:

    Platform	Directory
    UNIX	ORACLE_HOME/integration/interconnect/adapters/Application
    Windows	ORACLE_HOME\integration\interconnect\adapters\Application

    
    

    Application is the value specified in Step 5.

12. Click Exit on the Installation screen to exit the OA adapter installation.

Installing Multiple OA Adapters in the Same Oracle Home

To install multiple instances of the OA adapter in same Oracle home, use the copyAdapter script located in the ORACLE_HOME/integration/interconnect/bin directory.

Usage: copyAdapter app1 app2

For example, you have one instance of OA adapter with name myOAApp installed on a computer. To install another instance of the OA adapter with name myOAApp1 in the same Oracle home, use the following command:

copyAdapter myOAApp myOAApp1

The copyAdapter script is copied to the following bin directory only during Hub installation:

• UNIX: ORACLE_HOME/integration/interconnect/bin

• Windows: ORACLE_HOME\integration\interconnect\bin

If you need to use this script to create multiple adapters on a spoke computer, then copy the script to the bin directory on the spoke computer, and edit the script to reflect the new Oracle home.

After running the copyAdapter script, If you want to manage or monitor the newly installed adapter through Oracle Enterprise Manager 10g Application Server Control Console, then you need to modify the opmn.xml file by adding information about the new instance. For example, you have created a new instance of the OA adapter myOAApp1 by using the copyAdapter script. To manage the myOAApp1 adapter through Enterprise Manager, perform the following:

1. Navigate to the MiddleTier\bin directory and run the following command to stop the Enterprise Manager:

   emctl stop iasconsole
   
   

2. Next, specify the information about this new instance in the opmn.xml file located in the ORACLEMIDDLETIER_HOME/opmn/conf directory as follows:

   <process-type id="myOAApp1" module-id="adapter" working-dir="$ORACLE_
   HOME/integration/interconnect/adapters/myOAApp1" status="enabled">
          <start timeout="600" retry="2"/>
          <stop timeout="120"/>
          <port id="icadapter_dmsport_range" range="15701-15800"/>
          <process-set id="myOAApp1" restart-on-death="true" numprocs="1">
               <module-data>
                   <category id="start-parameters">

                       <data id="class-name"
                        value="oracle.oai.agent.service.AgentService"/>
                   </category>
                   <category id="stop-parameters">
                       <data id="java-parameters" value="-mx64m"/>

                       <data id="application-parameters"
                        value="persistence/Agent.ior"/>
                   </category>
               </module-data>
          </process-set>
   </process-type>
   
   

   The opmn.xml file would appear like this:

3. Save the opmn.xml file.

4. Navigate to the MiddleTier\opmn\bin directory and run the following command to reload the OPMN:

   opmnctl reload
   
   

5. You can start the myOAApp1 adapter by using the following command

   opmnctl startproc ias-component="InterConnect" process-type="myOAApp1"
   
   

6. Navigate to the MiddleTier\bin directory and run the following command to start the Enterprise Manager:

   emctl start iasconsole
   
   

7. Login to the Oracle Enterprise Manager 10g Application Server Control Console to view and manage the newly installed or copied adapter. For information about how to use Oracle Enterprise Manager 10g Application Server Control Console , refer to the Oracle Application Server Integration InterConnect User's Guide

Note: While installing multiple adapters in the same computer, the copyadapter script does not create entries for the new adapter's password in the Oracle Wallet. You need to manually create a password for this new adapter using the Oracle Wallet Manager. To store the password in Oracle Wallet, use the following format: ApplicationName/password The number of entries is dependent on the type of adapter. For example, Database Adapter needs two entries whereas AQ Adapter needs only one entry. For more information about how to manage your passwords in Oracle Wallet, refer to AppendixA, "How do I secure my passwords?" in Appendix A, "Frequently Asked Questions"
