void org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.cleanRecoveryLog (   )  throws SQLException

Possibly clean the recovery log after all recovery process are done. Exceptions: SQLException  if an error occurs

BackendRecoveryInfo org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.getBackendRecoveryInfo (  String  databaseName, String  backendName )  throws SQLException [package]

Retrieve recovery information on a backend. This includes, the last known state of the backend, and the last known checkpoint Parameters: databaseName  the virtual database name backendName  the backend name Returns: BackendRecoveryInfo instance or null if the backend does not exist Exceptions: SQLException  if cannot proceed

ArrayList org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.getCheckpointNames (   )  throws SQLException [package]

Returns an array of names of all the checkpoint available in the recovery log Returns: ArrayList of String checkpoint names Exceptions: SQLException  if fails

long org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.getCheckpointRequestId (  String  checkpointName  )  throws SQLException [package]

Get the request id corresponding to a given checkpoint. This is the first step in a recovery process. Following steps consist in calling recoverNextRequest. Parameters: checkpointName  Name of the checkpoint Returns: int the request identifier corresponding to this checkpoint. Exceptions: SQLException  if an error occurs

long org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.getLastTransactionId (   )  throws SQLException [package]

Get the id of the last transaction logged in the recovery log. Returns: the last transaction id. Exceptions: SQLException  if an error occurs

long org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.getRecoveringNb (   )  [package]

Returns the recoveringNb value. Returns: Returns the recoveringNb.

boolean org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.isRecovering (   )  [package]

Returns true if at least one backend has started a recover process. Returns: boolean

void org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.removeCheckpoint (  String  checkpointName  )  throws SQLException [package]

Remove a checkpoint from the recovery. This is useful for recovery maintenant Parameters: checkpointName  to remove Exceptions: SQLException  if an error occurs

void org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.storeBackendRecoveryInfo (  String  databaseName, BackendRecoveryInfo  backendRecoveryInfo )  throws SQLException [package]

Store the state of the backend in the recovery log Parameters: databaseName  the virtual database name backendRecoveryInfo  the backend recovery information to store Exceptions: SQLException  if cannot proceed

void org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.storeCheckpoint (  String  checkpointName, long  requestId )  throws SQLException [package]

Store a Checkpoint using the given request id. Parameters: checkpointName  Name of the checkpoint requestId  request identifier Exceptions: SQLException  if an error occurs

void org.objectweb.cjdbc.common.jmx.mbeans.AbstractRecoveryLogMBean.storeCheckpoint (  String  checkpointName  )  throws SQLException [package]

Store a Checkpoint using the current log state. Parameters: checkpointName  Name of the checkpoint Exceptions: SQLException  if an error occurs
