Direct Known Subclasses:

WebLogic_9_Platform

public class WebLogicPlatform
extends JMXServerPlatformBase

PUBLIC: This is the concrete subclass responsible for representing WebLogic-specific server behavior.

This platform overrides:

• getExternalTransactionControllerClass(): to use the WebLogic-specific controller class
• getServerNameAndVersion(): to call the WebLogic library for this information

Field Summary

Fields

Modifier and Type	Field	Description
protected Method	clearStatementCacheMethod	Cached WLConnection.clearStatementCache() Method used for clearing statement cache.
protected boolean	shouldClearStatementCache	Indicates whether WLConnection.clearStatementCache() should be called: there is no need to call it in WebLogic Server 10.3.4 or later.
protected Method	vendorConnectionMethod	Cached WLConnection.getVendorConnection() Method used for unwrapping connections.
protected Class	weblogicConnectionClass	Cached WLS connection class used to reflectively check connections and unwrap them.

Constructor Details

WebLogicPlatform

public WebLogicPlatform(DatabaseSession newDatabaseSession)

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

Method Details

initializeServerNameAndVersion

public void initializeServerNameAndVersion()

INTERNAL: Set the WLS version number through reflection.

Overrides:

initializeServerNameAndVersion in class ServerPlatformBase

getExternalTransactionControllerClass

public Class getExternalTransactionControllerClass()

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

Specified by:

getExternalTransactionControllerClass in interface ServerPlatform

Specified by:

getExternalTransactionControllerClass in class ServerPlatformBase

Returns:

Class externalTransactionControllerClass

See Also:

• JTATransactionController
• ServerPlatformBase.isJTAEnabled()
• ServerPlatformBase.disableJTA()
• ServerPlatformBase.initializeExternalTransactionController()

getWebLogicConnectionClass

protected Class getWebLogicConnectionClass()

Return the class (interface) for the WebLogic JDBC connection wrapper.

getVendorConnectionMethod

protected Method getVendorConnectionMethod()

Return the method for the WebLogic JDBC connection wrapper vendorConnection.

unwrapConnection

public Connection unwrapConnection(Connection connection)

Unwraps the WebLogic JDBC connection wrapping using the WebLogic API reflectively.

Specified by:

unwrapConnection in interface ServerPlatform

Overrides:

unwrapConnection in class ServerPlatformBase

getClearStatementCacheMethod

protected Method getClearStatementCacheMethod()

Return the method for the WebLogic connection clearStatementCache method.

clearStatementCache

public void clearStatementCache(Connection connection)

INTERNAL: Clears statement cache of WebLogic connection using the WebLogic API reflectively. 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

isJTA11

public boolean isJTA11()

INTERNAL: Check whether JTA 1.1 API is available. WLS older than 10.0 is not JTA 1.1 compliant.

Overrides:

isJTA11 in class ServerPlatformBase

Returns:

always returns false for WLS older than 10.0.
