Method Detail

refreshStatistics

void refreshStatistics()

Update the snapshot

clearStatistics

void clearStatistics()

Clear the statistics on all connections.

getTotalRequests

long getTotalRequests()

Obtains the total number of successfully submitted requests so far.

Returns:: The number of successfully submitted requests.

getTotalCompletedRequests

long getTotalCompletedRequests()

Obtains the total number of completed requests so far.

Returns:: The number of completed requests.

getTotalCalls

long getTotalCalls()

Obtains the total number of JDBC calls executed so far.

Returns:: The number of JDBC calls.

getTotalProtectedCalls

long getTotalProtectedCalls()

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

Returns:: The number of JDBC calls protected by AC.

getTotalCallsAffectedByOutages

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.

Returns:: The number of JDBC calls affected by outages.

getTotalCallsTriggeringReplay

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.

Returns:: The number of JDBC calls that triggered replay.

getTotalCallsAffectedByOutagesDuringReplay

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.

Returns:: The number of JDBC calls affected by outages during replay.

getSuccessfulReplayCount

long getSuccessfulReplayCount()

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

Returns:: The number of successful replays.

getFailedReplayCount

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.

Returns:: The number of successful replays.

getReplayDisablingCount

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 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.

Returns:: The number of times that replay is disabled.

getTotalReplayAttempts

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.

Returns:: The number of replay attempts.
