  • Method Details

    • isSuccess

      public boolean isSuccess()
      The operation succeeded.

    • isIgnore

      public boolean isIgnore()
      This message cannot be processed. This is an indication that this message is irrelevant to the current replication state (for example, an old message from a previous generation arrives and is processed late).

    • 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.

    • 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.

    • 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()
      Return the environment ID associated with the operation. In most cases, this is the same as the environment ID passed to Environment.processReplicationMessage. However, if a new master is elected, this method returns the environment ID of the new master. It is the application's responsibility to ensure that the matching node begins 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.

    • toString

      public String toString()
      Overrides:
      toString in class Object
