PoolMgr

public PoolMgr()

Method Detail

getInstance

public static PoolMgr getInstance()
Retrieves the singleton instance of the Pool Manager

destroy

public void destroy()
Description copied from class: ResourcePoolManager
Destroys the pool manager. Removes all resources from all of the pools that are managed by this pool manager.
Overrides:
destroy in class ResourcePoolManager

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)
Deprecated. 
Returns the ApplicationPool interface for the named pool.
Since:
5.0
See Also:
ResourcePoolManager.getResourcePool(Object)

addPool

public void addPool(ApplicationPool pool)
Deprecated. 
Adds the pool to the pool manager collection.
Parameters:
pool - the pool to add.
Since:
5.0
See Also:
ResourcePoolManager.addResourcePool(Object, Object)

removePool

public void removePool(java.lang.String sName)
Deprecated. 
Removes the named pool and calls remove() method on all ApplicationModule instances that are being managed by the pool.
Parameters:
sName - name of the pool to remove.
Since:
5.0
See Also:
ResourcePoolManager.removeResourcePool(Object)

getPools

public java.util.Enumeration getPools()
Deprecated. 
Returns the Enumeration interface that allows you to enumerate through all the Application Pools that are registered with the Pool Manager.
Since:
5.0
See Also:
ResourcePoolManager.getResourcePools()

getPoolNames

public java.util.Enumeration getPoolNames()
Deprecated. 
Since:

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 ApplicationModules 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.
Throws:
java.lang.Exception

createPool

public ApplicationPool createPool(java.lang.String sName,
                                  java.lang.String sApplicationModule,

                           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 ApplicationModules 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.

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
Throws:
java.lang.Exception
