Method Detail

refreshStatistics

public void refreshStatistics()

Description copied from interface: JDBCReplayStatisticsRuntimeMBean

Update the snapshot

Specified by:

refreshStatistics in interface JDBCReplayStatisticsRuntimeMBean

clearStatistics

public void clearStatistics()

Description copied from interface: JDBCReplayStatisticsRuntimeMBean

Clear the statistics on all connections.

Specified by:

clearStatistics in interface JDBCReplayStatisticsRuntimeMBean

getTotalRequests

public long getTotalRequests()

Obtains the total number of successfully submitted requests so far.

Specified by:

getTotalRequests in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of successfully submitted requests.

getTotalCompletedRequests

public long getTotalCompletedRequests()

Obtains the total number of completed requests so far.

Specified by:

getTotalCompletedRequests in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of completed requests.

getTotalCalls

public long getTotalCalls()

Obtains the total number of JDBC calls executed so far.

Specified by:

getTotalCalls in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of JDBC calls.

getTotalProtectedCalls

public long getTotalProtectedCalls()

Obtains the total number of JDBC calls executed so far that are protected by AC.

Specified by:

getTotalProtectedCalls in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of JDBC calls protected by AC.

getTotalCallsAffectedByOutages

public long getTotalCallsAffectedByOutages()

Obtains the number of JDBC calls affected by outages. This includes both local calls and calls that involve roundtrip(s) to the database server.

Specified by:

getTotalCallsAffectedByOutages in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of JDBC calls affected by outages.

getTotalCallsTriggeringReplay

public long getTotalCallsTriggeringReplay()

Obtains the number of JDBC calls that triggered replay. Not all the calls affected by an outage trigger replay, because replay can be disabled for some requests.

Specified by:

getTotalCallsTriggeringReplay in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of JDBC calls that triggered replay.

getTotalCallsAffectedByOutagesDuringReplay

public long getTotalCallsAffectedByOutagesDuringReplay()

Obtains the number of JDBC calls affected by outages in the middle of replay. Outages may be cascaded and strike a call multiple times when replay is ongoing. AC automatically reattempts replay when this happens, unless it reaches the maximum retry limit.

Specified by:

getTotalCallsAffectedByOutagesDuringReplay in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of JDBC calls affected by outages during replay.

getSuccessfulReplayCount

public long getSuccessfulReplayCount()

Obtains the number of replays that succeeded. Successful replays mask the outages from applications.

Specified by:

getSuccessfulReplayCount in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of successful replays.

getFailedReplayCount

public long getFailedReplayCount()

Obtains the number of replays that failed.

When replay fails, it rethrows the original SQLRecoverableException to the application, with the reason for the failure chained to that original exception. Application can call getNextException to retrieve the reason.

Specified by:

getFailedReplayCount in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of successful replays.

getReplayDisablingCount

public long getReplayDisablingCount()

Obtains the number of times that replay is disabled. When replay is disabled in the middle of a request, the remaining calls in that request are no public longer protected by AC. In case an outage strikes one of those remaining calls, no replay will be attempted, and application simply gets an SQLRecoverableException.

Specified by:

getReplayDisablingCount in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of times that replay is disabled.

getTotalReplayAttempts

public long getTotalReplayAttempts()

Obtains the number of replay attempts. AC automatically reattempts when replay fails, so this number may exceed the number of JDBC calls that triggered replay.

Specified by:

getTotalReplayAttempts in interface JDBCReplayStatisticsRuntimeMBean

Returns:

The number of replay attempts.

getWorkManagerRuntimes

public WorkManagerRuntimeMBean[] getWorkManagerRuntimes()

Description copied from interface: ComponentRuntimeMBean

Get the runtime mbeans for all work managers defined in this component

Specified by:

getWorkManagerRuntimes in interface ComponentRuntimeMBean

addWorkManagerRuntime

public boolean addWorkManagerRuntime(WorkManagerRuntimeMBean wmRuntime)

Description copied from interface: ComponentRuntimeMBean

Adds the RuntimeMBean for a WorkManager defined in this component

Specified by:

addWorkManagerRuntime in interface ComponentRuntimeMBean

setDeploymentState

public void setDeploymentState(int state)

Description copied from interface: ComponentRuntimeMBean

Sets the value of the deploymentState attribute.

Specified by:

setDeploymentState in interface ComponentRuntimeMBean

Parameters:

state - The new deploymentState value

See Also:

ComponentRuntimeMBean.getDeploymentState()

getDeploymentState

public int getDeploymentState()

Description copied from interface: ComponentRuntimeMBean

The current deployment state of the module.

A module can be in one and only one of the following states. State can be changed via deployment or administrator console.

• UNPREPARED. State indicating at this module is neither prepared or active.
• PREPARED. State indicating at this module of this application is prepared, but not active. The classes have been loaded and the module has been validated.
• ACTIVATED. State indicating at this module is currently active.
• NEW. State indicating this module has just been created and is being initialized.

Specified by:

getDeploymentState in interface ComponentRuntimeMBean

Returns:

The deploymentState value

See Also:

ComponentRuntimeMBean.setDeploymentState(int)

getModuleId

public java.lang.String getModuleId()

Description copied from interface: ComponentRuntimeMBean

Returns the identifier for this Component. The identifier is unique within the application.

Typical modules will use the URI for their id. Web Modules will return their context-root since the web-uri may not be unique within an EAR.

Specified by:

getModuleId in interface ComponentRuntimeMBean

Returns:

the module id
