Installation Tasks

To install the AQ adapter:

Select OracleAS Integration InterConnect Adapter for AQ 10.1.2.0.2 in the Available Product Components screen of the OracleAS Integration InterConnect installation wizard.
Click Next. 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 5 if installing the AQ 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 6 if installing the AQ 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.
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 System Identifier (SID) for the hub database.
- Password: The user password for the hub database user.
Click Next. The Specify AQ Adapter Name screen is displayed.

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

Note:

You can change the application name in iStudio after installation. In such 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":

Click Next. The Specify Spoke Application Database Connection screen is displayed. This screen configures the information for the spoke application database. Enter information in the following fields:
- Host Name: The name of the computer where the spoke application database is installed.
- Port Number: The TNS listener port for the spoke application database.
- Database SID: The SID for the spoke application database.
The information on this screen is for Advanced Queues, from which the adapter will deliver or receive messages.
Click Next. The Spoke Application Database AQ Username screen is displayed. Enter information in the following fields:
- User Name: The name the AQ adapter uses to connect to the database.
- Password: The password for the user name.
- Consumer Name: The consumer name used by the application that writes to the queue. The consumer name indicates that OracleAS Integration InterConnect should pick up a message. Alternatively, the AQ adapter may have a subscriber configured to which the AQ adapter corresponds.
  
  Leave this field blank if the queues that the AQ adapter will connect to on the application database side are single consumer queues. However, if any of the queues are multiconsumer queues, then specify a consumer name.
  
  Use one of the following methods to determine the consumer name to use:
  - If the code that will write a message to the queue is already available, then look at the code or the documentation that comes with it to determine the consumer name.
  - If the code that will write a message to the queue is not written, then enter a string as the consumer name. When the code is built, ensure that the consumer names match. Alternatively, if the queue has a subscriber configured, then use the database's Advanced Queuing APIs to find the name.
Click Next. The Summary screen is displayed.
Click Install to install the AQ adapter and other selected components. The AQ adapter is installed in the following directory:

Platform Directory

Windows ORACLE_HOME\integration\interconnect\adapters\Application

UNIX ORACLE_HOME/integration/interconnect/adapters/Application

Application is the value specified in Step 7.
Click Exit on the Installation screen to exit the AQ adapter installation.

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

Installing Multiple AQ Adapters in the Same Oracle Home

To install multiple instances of the AQ 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 AQ adapter with name myAQApp installed on a computer. To install another instance of the AQ adapter with name myAQApp1 in the same Oracle home, use the following command:

copyAdapter myAQApp myAQApp1

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 AQ adapter myAQApp1 by using the copyAdapter script. To manage the myAQApp1 adapter through Enterprise Manager, perform the following:

Navigate to the MiddleTier\bin directory and run the following command to stop the Enterprise Manager:
```
emctl stop iasconsole
```

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="myAQApp1" module-id="adapter" working-dir="$ORACLE_
HOME/integration/interconnect/adapters/myAQApp1" status="enabled">

Save the opmn.xml file.
Navigate to the MiddleTier\opmn\bin directory and run the following command to reload the OPMN:
```
opmnctl reload
```

You can start the myAQApp1 adapter by using the following command

opmnctl startproc ias-component="InterConnect" process-type="myAQApp1"

Navigate to the MiddleTier\bin directory and run the following command to start the Enterprise Manager:
```
emctl start iasconsole
```
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"

Configuring the AQ Adapter

You can configure the AQ adapter according to your requirements. The following tables describe the location and details of the configuration files.

Table 2-1 describes the location where the adapter is installed:

Table 2-1 AQ Adapter Directory

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

Table 2-2 describes the various executable files of the AQ adapter.

Table 2-2 Executable Files

File	Description
`start` (UNIX)	Does not use parameters; starts the adapter.
`start.bat` (Windows)	Does not use parameters; starts the adapter.
`stop` (UNIX)	Does not use parameters; stops the adapter.
`stop.bat` (Windows)	Does not use parameters; stops the adapter.

Table 2-3 describes the AQ adapter configuration files.

Table 2-3 Configuration Files

File	Description
`adapter.ini` (UNIX)	Contains all the initialization parameters, which the adapter reads at startup.
`adapter.ini` (Windows)	Contains all the initialization parameters, which the adapter reads at startup.

Table 2-4 describes the directories used by the AQ adapter.

Table 2-4 Directories

File	Description
`logs`	The adapter activity is logged in subdirectories of the `logs` directory. Each time the adapter is run, a new subdirectory is created for the `log.xml` log file.
`persistence`	The messages are persisted in this directory. Do not edit this directory or its files.

Using the Application Parameter

Adapters do not have integration logic. The AQ adapter has a generic transformation engine that processes metadata from the repository as run-time instructions to perform transformations. The application parameter defines the capabilities of an adapter, such as the messages to be published and subscribed, and the transformations to be performed. The application parameter allows the adapter to retrieve only the relevant metadata from the repository. The application parameter must match the corresponding application that will be defined in iStudio, under the Applications folder.

If you use pre-packaged metadata, then import it into the repository and start iStudio to find the corresponding application under the Applications folder. You can use this as the application name for the adapter you are installing.

AQ Adapter Ini File Settings

The following .ini files are used to configure the AQ adapter:

hub.ini File
adapter.ini File

hub.ini File

The AQ adapter connects to the hub database using parameters in the hub.ini file located in the hub directory. Table 2-5 lists the description and an example for each parameter.

Table 2-9 lists the parameters specific to the AQ adapter.

Table 2-9 AQ Adapter-Specific Parameters

Parameter	Description	Example
`aq_bridge_consumer_name`	If all the queues that this adapter will connect to on the application database side are single consumer queues, then this can be left blank. If, however, any of the queues is a multiconsumer queue, then specify a consumer name. Possible value: `aq_bridge_username` Default value: None Note: If you are integrating B2B with OracleAS Integration InterConnect, then set the parameter `aq_bridge_consumer_name` to `b2b_user`. Also set the AQ adapter to listen on `IP_IN_QUEUE`. For example, aq_bridge_consumer_name=`b2b_user`.	`aq_bridge_consumer_name=aquser`
`aq_bridge_host`	Name of the computer hosting the database instance specified by `aq_bridge_instance`. Default value: None	`aq_bridge_host=mpscott-pc`
`aq_bridge_instance`	The SID of the database instance. Default value: None	`aq_bridge_instance=orcl`
`aq_bridge_owner`	The owner of the advanced queue. Possible value: `aq_bridge_username` Default value: None	`aq_bridge_owner=aquser`
`aq_bridge_password`	The password corresponding to the `aq_bridge_username` parameter. Possible value: `aquser` Default value: None Note: All passwords are stored in Oracle Wallet.
