Constructor Detail

FBBackupManagerBase

public FBBackupManagerBase()

Create a new instance of FBBackupManagerBase based on the default GDSType.

FBBackupManagerBase

public FBBackupManagerBase(java.lang.String gdsType)

Create a new instance of FBBackupManagerBase based on a given GDSType.

Parameters:

gdsType - type must be PURE_JAVA, EMBEDDED, or NATIVE

Method Detail

addBackupPath

public void addBackupPath(java.lang.String path)

Description copied from interface: BackupManager

Add backup file to the list. This method is used only during restoring the database to specify multi-file backups. The call is equivalent to passing the size -1 to BackupManager.addBackupPath(String, int) call.

If application invokes backup operation, an error is generated in that call.

Specified by:

addBackupPath in interface BackupManager

Parameters:

path - path to the backup file.

setDatabase

public void setDatabase(java.lang.String database)

Description copied from interface: ServiceManager

Sets the database path for the connection to the service manager.

Will also set the expectedDb property. If a different value must be used, it must be set after calling this method.

Specified by:

setDatabase in interface BackupManager

Specified by:

setDatabase in interface ServiceManager

Overrides:

setDatabase in class FBServiceManager

Parameters:

database - path for the connection to the service manager.

addRestorePath

public void addRestorePath(java.lang.String path,
                           int size)

Description copied from interface: BackupManager

Add the file to the multi-file database of the specified size for restore operation.

Specified by:

addRestorePath in interface BackupManager

Parameters:

path - path to the backup file.

size - max size of the database file in pages.

clearRestorePaths

public void clearRestorePaths()

Description copied from interface: BackupManager

Clear the information about restore paths. This method undoes all parameters set in the BackupManager.addRestorePath(String, int) or BackupManager.setDatabase(String) methods.

Specified by:

clearRestorePaths in interface BackupManager

backupDatabase

public void backupDatabase()
                    throws java.sql.SQLException

Description copied from interface: BackupManager

Perform the backup operation.

Specified by:

backupDatabase in interface BackupManager

Throws:

java.sql.SQLException - if a database error occurs during the backup

backupMetadata

public void backupMetadata()
                    throws java.sql.SQLException

Description copied from interface: BackupManager

Perform the backup operation, metadata only.

Specified by:

backupMetadata in interface BackupManager

Throws:

java.sql.SQLException - if a database error occurs during the backup

getBackupSRB

protected ServiceRequestBuffer getBackupSRB(FbService service,
                                            int options)
                                     throws java.sql.SQLException

Creates and returns the "backup" service request buffer for the Service Manager.

Parameters:

Throws:

java.sql.SQLException - if a database error occurs during the restore

setVerbose

public void setVerbose(boolean verbose)

Set whether the operations of this BackupManager will result in verbose logging to the configured logger.

Specified by:

setVerbose in interface BackupManager

Parameters:

verbose - If true, operations will be logged verbosely, otherwise they will not be logged verbosely

setRestorePageBufferCount

public void setRestorePageBufferCount(int bufferCount)

Set the default number of pages to be buffered (cached) by default in a restored database.

Specified by:

setRestorePageBufferCount in interface BackupManager

Parameters:

bufferCount - The page-buffer size to be used, a positive value

setRestorePageSize

public void setRestorePageSize(int pageSize)

Set the page size that will be used for a restored database. The value for pageSize must be one of PageSizeConstants. The default value depends on the Firebird version.
