Using the Java Connection Factory

Pooling with Server Attributes Read from the Information Service

The process of creating a pooling server by using the Information Service is basically the same as the process that is described at Connecting with Server Attributes Read from the Information Service, but the following additional steps are required when you create a pooling server:

create a user context for the pooling administrator user, who can access the metadata for the puddle logins. For more information about the pooling administrator, see Configuring Client-side Pooling in the SAS Intelligence Platform: Application Server Administration Guide.
specify the name or the user context for the pooling administrator in the constructor method for PlatformConnectionFactoryConnection.

The following example code shows how to create a pooling server using the Information Service. For information about how to use the object reference, see Java Connection Factory Language Service Example.

The last three statements in the example code show how to dispose of object references. For details about this procedure, see Returning Connections to the Java Connection Factory.

< set up the User Service and create a UserServiceInterface
uService >

// Step 1. Create a user context for the pool administrator
UserContextInterface poolUser = uService.newUser("pooladm","pooladmpw",
   "pooladmdomain");

// Step 2. Create a user context for a connection factory user
UserContextInterface cxfUser = uService.newUser("user1","user1pw",
   "user1domain");

< set up the Information Service and define a repository
repos >

// Step 3. Identify the repository
RepositoryInterface cxfRepos = cxfUser.getRepository("repos");

// Step 4. Identify the IOM service
LogicalServerInterface logicalServer =
   cxfRepos.fetch("A50IFJQG.AQ000002/LogicalServer");

// Step 5. Create a connection factory configuration
String poolUserName = poolUser.getName();
ConnectionFactoryConfiguration cxfConfig = new
   PlatformConnectionFactoryConfiguration(logicalServer, poolUserName);

// Step 6. Get a connection factory manager
PlatformConnectionFactoryManager cxfManager = new
   PlatformConnectionFactoryManager();

// Step 7. Get a connection factory using the configuration
PlatformConnectionFactoryInterface cxf =
   cxfManager.getPlatformFactory(cxfConfig);

// Step 8. Get a connection
ConnectionInterface cx = cxf.getConnection(cxfUser);

// Step 9. Narrow the connection
org.omg.CORBA.Object obj = cx.getObject();
IWorkspace iWorkspace = IWorkspaceHelper.narrow(obj);

< insert iWorkspace workspace usage code here >// Step 10. Close the connection when finished
cx.close();
cxf.getAdminInterface().destroy();

Note: To make the previous example more readable, we have removed most of the code structuring elements. The example will not compile as it is shown. [cautionend]
