Install and configure the SDO repository

Service Data Objects (SDO) is an open standard for enabling applications to handle data from different data sources in a uniform way, as data graphs. Service integration bus-enabled web services use an SDO repository for storing and serving WSDL definitions. Use this task to create and configure your preferred database to store SDO data, and to install and configure an SDO repository on each server to use for bus-enabled web services.

Determine the servers on which to install and configure an SDO repository as described in Planning your bus-enabled web services installation, then add each server as a member of a bus as described in Configure the members of a bus.

An SDO repository can work with most database products. For specific information about choosing and configuring your preferred database, consult the database administrator or database product documentation, and read the notes in this topic on database usage. To install and configure an SDO repository...

• Install your preferred database product.

• Create a JDBC provider and a data source for the database.

• Run the installSdoRepository.jacl script one or more times, to install the SDO application on each server and to set the database type the SDO repository is to use.

For more information about how to do this, first read the following notes on database usage and on the installSdoRepository.jacl script, and then complete the steps for one of these configurations:

• Configure the SDO repository for a single server, and to use the embedded Derby database.
• Configure the SDO repository for a single server, and to use a database other than embedded Derby.

Notes on database usage:

• For a single server configuration, we can use either your preferred database or the embedded Apache Derby database supplied with WebSphere Application Server.
• The SDO repository dictates the schema and table names that it uses, so different repositories must use different databases to ensure they do not access the same data.

• Create the database for the preferred database supplier using the Table.ddl file from the relevant app_server_root/util/SdoRepository/database_type directory. The Table.ddl file describes the database table needed by the SDO repository.
• The -editBackendId flag on the installSdoRepository.jacl script determines the database type the repository is to use. The back end ID determines what database-specific rules the application follows when talking to the database. See the associated note on the installSdoRepository.jacl script.
• Some databases require a user ID that has been granted permissions to access the SDO repository database. Create a user ID for user name SDOREP before you create the tables for Oracle, Sybase, and SQL Server databases. Because of the way these databases handle user names and table names, the user name must be SDOREP to enable the SDO repository to access its table with the fully qualified name SDOREP.BYTESTORE. Make sure that you grant permission for the SDOREP user to read from, and write to, the database.

• If we use an Informix database, do not disable logging.
• The SDO repository does not require XA support. In most cases we can use either an XA or a non-XA data source. However, if the database is Oracle 8 or 9, use the Oracle JDBC driver (non-XA) for the SDO repository data source.
• You might also choose to complete other steps such as creating an index of the primary key to improve database performance. Do not change the schema, table and column names.

Notes on the installSdoRepository.jacl script:

• Use the wsadmin scripting client to run the script.
• The script is provided in the app_server_root/bin directory, where app_server_root is the root directory for the installation of WAS. If you choose to run the wsadmin scripting client from another directory, specify the full path to the script on the command option. For example to work with a profile other than the default profile, change to the app_server_root/profiles/profile_name/bin directory then specify the following path to the script:
  wsadmin.ext -f app_server_root/bin/installSdoRepository.jacl
  where .ext is the file extension .bat for a Windows system, or .sh for a UNIX, Linux or z/OS system.
• The -editBackendId flag on the installSdoRepository.jacl script determines the database type the repository is to use. The back end ID determines what database-specific rules the application follows when talking to the database. To see the full list of available back end ID values, use the -listBackendIds flag:
  wsadmin -f installSdoRepository.jacl -listBackendIds
  All the back end ID values in the list can be used when the SDO repository is installed on one or more WAS v7.0 or later application servers. Values marked with (*) cannot be used when the SDO repository is installed on v6.0 servers. Values marked with (**) cannot be used when the SDO repository is installed on v6.0 or v6.1 servers.

• If the data source already exists, or there has been a previous broken or partial installation of the SDO repository application, the installSdoRepository.jacl script fails to complete and configuration changes are not saved. In these cases, run the SDO repository uninstall script, fix the problem, then rerun the installSdoRepository.jacl script.

Configure the SDO repository for a single server, and to use the embedded Derby database

About this task

If you are creating a single server configuration and to use embedded Derby, you run the installSdoRepository.jacl script with the -createDb switch. This action creates the Derby database and installs the SDO repository.

To configure the SDO repository for a single server and to use the embedded Derby database...

Procedure

1. Open a command prompt, then change to the app_server_root/bin directory.

2. Enter the following command:
   wsadmin.ext -f installSdoRepository.jacl -createDb

   The -createDb flag tells the command to create a default Derby database. If you omit this flag, the command still installs an SDO repository that is configured to use Derby, but the command does not also create the database.

Configure the SDO repository for a single server, and to use a database other than embedded Derby

About this task

If you are creating a single server configuration that uses a database other than embedded Derby, you install your preferred database product, then create a JDBC provider and a data source, then run the installSdoRepository.jacl script twice:

1. One time to install the SDO application on the application server.

2. One time to set the database type the SDO repository is to use.

To configure the SDO repository for a single server and to use a database other than embedded Derby...

Procedure

1. Create the database for the preferred database supplier using the Table.ddl file from the relevant app_server_root/util/SdoRepository/database_type directory.
   

   For an illustration of the process for creating tables in DB2 , see Recreating database tables from the exported table data definition language. For more information, see Deploy data access applications.

2. Create a J2C authentication alias.

   This is for use with the data source that you create in the next step. Check the authentication alias matches the login details for the database instance, otherwise a connection will not be made.

3. Create and configure a JDBC provider and data source.

   Set the following data source properties:

   • Set the authentication property to use the authentication alias you created in the previous step.

   • Select the Use this Data Source in container managed persistence (CMP) check box.

   • Set the Name property to a name of our own choosing. For example, SDO Repository DataSource.

   • Set the JNDI name property to the following exact value: jdbc/com.ibm.ws.sdo.config/SdoRepository.

   • Set any other properties that are required settings for the chosen database.

4. Optional: Test the data source connection:

   This option does not work in all configurations. The availability of this option depends on the scope at which the data source is defined, and the scope of any WAS variables used in the JDBC provider and data source configurations. For more information about testing connections to data sources, see Test connection service.

   1. In the dmgr console, navigate to Resources -> JDBC -> Data sources.

   2. Select the SDO repository data source.

   3. Click Test connection.

5. Configure the SDO repository:
   
   1. Open a command prompt, then change to the app_server_root/bin directory.
      
   2. Install the SDO repository application on the server:
      wsadmin.ext -f installSdoRepository.jacl

   3. Set the database type the SDO repository is to use:
      
      wsadmin.ext -f installSdoRepository.jacl -editBackendId database_type
      for example:
      wsadmin.ext -f installSdoRepository.jacl -editBackendId DB2UDB_V82
