Enum RecoveryProgress

java.lang.Object
  java.lang.Enum<RecoveryProgress>
      com.sleepycat.je.RecoveryProgress

All Implemented Interfaces:

Serializable, Comparable<RecoveryProgress>

public enum RecoveryProgress
extends Enum<RecoveryProgress>

Describes the different phases of initialization that be executed when an Environment is instantiated. Meant to be used in conjunction with a ProgressListener that is configured through EnvironmentConfig.setRecoveryProgressListener(com.sleepycat.je.ProgressListener) to monitor the cost of environment startup

Since:

5.0

Enum Constant Summary

BECOME_CONSISTENT
For replicated systems only: if a replica, process enough of the replication stream so that the environment fulfills the required consistency policy, as defined by parameters passed to the ReplicatedEnvironment constructor.

CKPT
Perform a checkpoint to make all the work of this environment startup persistent, so it is not repeated in future startups.

FIND_END_OF_LOG
Find the last valid entry in the database log.

FIND_LAST_CKPT
Find the last complete checkpoint in the database log.

FIND_MASTER
For replicated systems only: locate the master of the replication group by querying others in the group, and holding an election if necessary.

POPULATE_UTILIZATION_PROFILE
Populate internal metadata which stores information about the utilization level of each log file, for efficient log cleaning.

READ_DATA_INFO
Read log entries that pertain to the database indices.

READ_DBMAP_INFO
Read log entries that pertain to the database map, which is an internal index of all databases.

RECOVERY_FINISHED
Basic recovery is completed, and the environment is able to service operations.

REDO_DATA_INFO
Re-read log entries that pertain to the database indices when they appear after a btree split.

REDO_DATA_RECORDS
Repeat committed data operations, such as inserts, updates and deletes.

REDO_DBMAP_INFO
Re-read log entries that pertain to the database map when they appear after a btree split.

REDO_DBMAP_RECORDS
Redo committed database creation, deletion and truncations.

REMOVE_TEMP_DBS
Remove temporary databases created by the application that are no longer valid.

UNDO_DATA_RECORDS
Rollback uncommitted data operations, such as inserts, updates and deletes.

UNDO_DBMAP_RECORDS
Rollback uncommitted database creation, deletion and truncations.

Method Detail

values

public static RecoveryProgress[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RecoveryProgress c : RecoveryProgress.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static RecoveryProgress valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
