Method Detail

isSuccess

public boolean isSuccess()

The operation succeeded.

isDupMaster

public boolean isDupMaster()

The replication group has more than one master. The application should reconfigure itself as a client by calling the Environment.startReplication method, and then call for an election by calling Environment.electReplicationMaster.

isHoldElection

public boolean isHoldElection()

An election is needed. The application should call for an election by calling Environment.electReplicationMaster.

isPermanent

public boolean isPermanent()

Processing this message resulted in the processing of records that are permanent. The maximum LSN of the permanent records stored is available from the getLSN method.

isNewMaster

public boolean isNewMaster()

A new master has been elected. The environment ID of the new master is available from the getEnvID method. If the recipient of this error return has been made master, it is the application's responsibility to begin acting as the master environment.

isNewSite

public boolean isNewSite()

The system received contact information from a new environment. A copy of the opaque data specified in the cdata parameter to the Environment.startReplication is available from the getCDAta method. The application should take whatever action is needed to establish a communication channel with this new environment.

isNotPermanent

public boolean isNotPermanent()

A message carrying a DB_REP_PERMANENT flag was processed successfully, but was not written to disk. The LSN of this record is available from the getLSN method. The application should take whatever action is deemed necessary to retain its recoverability characteristics.

isStartupDone

public boolean isStartupDone()

The client completed startup synchronization. The client application knows this client is now processing live log records received from the master.

getCData

public DatabaseEntry getCData()

Whenever the system receives contact information from a new environment, a copy of the opaque data specified in the cdata parameter to the Environment.startReplication is available from the getCDAta method. The application should take whatever action is needed to establish a communication channel with this new environment.

getEnvID

public int getEnvID()

Whenever a new master is elected, the environment ID of the new master is available from the getEnvID method. If the recipient of this error return has been made master, it is the application's responsibility to begin acting as the master environment.

getLSN

public LogSequenceNumber getLSN()

Whenever processing a messages results in the processing of messages that are permanent, or a message carrying a DB_REP_PERMANENT flag was processed successfully, but was not written to disk, the LSN of the record is available from the getLSN method. The application should take whatever action is deemed necessary to retain its recoverability characteristics.
