ServerPlatform

public class Oc4jPlatform
extends ServerPlatformBase

PUBLIC: This is the concrete subclass responsible for representing Oc4j-specific server behavior. This platform overrides: getExternalTransactionControllerClass(): to use an Oc4j-specific controller class initializeServerNameAndVersion(): to call an Oc4j library for this information

public Oc4jPlatform(DatabaseSession newDatabaseSession)

INTERNAL: Default Constructor: All behavior for the default constructor is inherited

Method Detail

getExternalTransactionControllerClass

public java.lang.Class getExternalTransactionControllerClass()

INTERNAL: getExternalTransactionControllerClass(): Answer the class of external transaction controller to use for Oc4j. This is read-only.

Specified by:

getExternalTransactionControllerClass in interface ServerPlatform

Specified by:

getExternalTransactionControllerClass in class ServerPlatformBase

Returns:

Class externalTransactionControllerClass

unwrapConnection

public java.sql.Connection unwrapConnection(java.sql.Connection connection)

INTERNAL: This method is used to unwrap the oracle connection wrapped by the application server. TopLink needs this unwrapped connection for certain Oracle Specific support. (ie TIMESTAMPTZ)

Specified by:

unwrapConnection in interface ServerPlatform

Overrides:

unwrapConnection in class ServerPlatformBase

clearStatementCache

public void clearStatementCache(java.sql.Connection connection)

INTERNAL: Clears statement cache of the wrapper connection. Required by Oracle proxy authentication: currently connection statement cache becomes invalid on switching to/from proxy session. This method is called by OracleJDBC_10_1_0_2ProxyConnectionCustomizer before opening proxy session and before closing it.

Specified by:

clearStatementCache in interface ServerPlatform

Overrides:

clearStatementCache in class ServerPlatformBase
