Method Detail

getInstance

public static PoolMgr getInstance()

Retrieves the singleton instance of the Pool Manager

isPoolCreated

public boolean isPoolCreated(java.lang.String sName)

Returns true if the pool has already been created.

getPool

public ApplicationPool getPool(java.lang.String sName)

Returns the ApplicationPool interface for the named pool.

removePool

public void removePool(java.lang.String sName)

Removes the named pool and calls remove() method on all ApplicationModule instances that are being managed by the pool.

Parameters:

the - name of the pool to remove.

createPool

public ApplicationPool createPool(java.lang.String sName,
                                  java.lang.String sClass,
                                  java.lang.String sApplicationModule,
                                  java.lang.String sConnectString,
                                  java.util.Hashtable env)
                           throws java.lang.Exception

Create a new Application Module pool, throws an exception if the pool is already registered. The connectInfo parameter provides the necessary settings required for creating instances of Application Modules that are part of the pool. You can also specify the name of the class that implements the ApplicationPool interface. This is an important setting for users that want to provide a custom implementation of the ApplicationPool interface. The default ApplicationPool implementation is in the oracle.jbo.client.ampool.ApplicationPoolImpl class.

createPool

public ApplicationPool createPool(java.lang.String sName,
                                  java.lang.String sApplicationModule,
                                  java.lang.String sConnectString,
                                  java.util.Hashtable env)
                           throws java.lang.Exception

Create a new Application Module pool, throws an exception if the pool is already registered. The connectInfo parameter provides the necessary settings required for creating instances of Application Modules that are part of the pool. You can also specify the name of the class that implements the ApplicationPool interface. This is an important setting for users that want to provide a custom implementation of the ApplicationPool interface. The default ApplicationPool implementation is in the oracle.jbo.client.ampool.ApplicationPoolImpl class.

getPools

public java.util.Enumeration getPools()

Returns the Enumeration interface that allows you to enumerate through all the Application Pools that are registered with the Pool Manager.

getPoolNames

public java.util.Enumeration getPoolNames()

createPool

public ApplicationPool createPool(java.lang.String sName,
                                  java.lang.String sPackageName,
                                  java.lang.String sConfigName,
                                  java.util.Properties props)
                           throws java.lang.Exception

Creates a new Application Module pool, throws an exception if the pool is already registered.

This method creates an Application Module pool, based on the named AppModule Configuaraion

The application module configuration provides the necessary settings required for creating instances of Application Modules that are part of the pool. You can also specify the name of a custom application pool implementation (implements oracle.jbo.common.ApplicationPool interface). The default ApplicationPool implementation is provided in oracle.jbo.common.ampool.ApplicationPoolImpl.

Parameters:

sName - name of the pool

sPackageName - package name of the AppModule., package10, for package10.Package10Module

sConfigName - named Configuration to use

props - collection of additional properties to be passed to the application pool
