 org.apache.derby.impl.store.raw.log.ReadOnly
| ReadOnly | | public class ReadOnly implements LogFactory,ModuleSupportable(Code) | | A read-only version of the log factory.
It doesn't do anything, it doesn't check that
the database needs recovery or not.
It doesn't handle undo. No recovery.
Multithreading considerations:
This class must be MT-safe.

| Method Summary | |
| public void | abortLogBackup()
| | public boolean | canSupport(Properties startParams)
| | public boolean | checkVersion(int requiredMajorVersion, int requiredMinorVersion, String feature)
Check to see if a database has been upgraded to the required
level in order to use a store feature.
This method is generally used to prevent writes to
data/log file by a particular store feature until the
database is upgraded to the required version. | | public boolean | checkpoint(RawStoreFactory rawStoreFactory, DataFactory dataFactory, TransactionFactory transactionFactory, boolean wait)
| | public void | checkpointInRFR(LogInstant cinstant, long redoLWM, DataFactory df)
| | public void | deleteLogFileAfterCheckpointLogFile()
| | public void | deleteOnlineArchivedLogFiles()
| | public void | disableLogArchiveMode()
| | public void | enableLogArchiveMode()
| | public void | endLogBackup(File toDir)
| | public void | flush(LogInstant where)
| | public void | freezePersistentStore()
| | public String | getCanonicalLogPath()
| | public LogInstant | getFirstUnflushedInstant()
| | public StorageFile | getLogDirectory()
| | public void | getLogFactoryProperties(PersistentSet set)
| | public Logger | getLogger()
| | public LogInstant | getTruncationLWM(UUID name)
| | public boolean | inRFR()
| | public boolean | isCheckpointInLastLogFile()
| | public boolean | logArchived()
Backup restore - is the log being archived to some directory?
if RawStore.LOG_ARCHIVAL_DIRECTORY is set to some value, that means the
log is meant to be archived. | | public StandardException | markCorrupt(StandardException originalError)
| | public ScanHandle | openFlushedScan(DatabaseInstant i, int groupsIWant)
| | public LogScan | openForwardsFlushedScan(LogInstant startAt)
| | public LogScan | openForwardsScan(LogInstant startAt, LogInstant stopAt)
| | public void | recover(RawStoreFactory rawStoreFactory, DataFactory dataFactory, TransactionFactory transactionFactory)
| | public void | removeTruncationLWM(UUID name, RawStoreFactory rawStoreFactory, TransactionFactory transFactory)
| | public void | removeTruncationLWM(UUID name)
| | public void | setDatabaseEncrypted(boolean flushLog)
| | public LogInstant | setTruncationLWM(UUID name, LogInstant instant, RawStoreFactory rawStoreFactory, TransactionFactory transFactory)
| | public void | setTruncationLWM(UUID name, LogInstant instant)
| | public void | startLogBackup(File toDir)
| | public void | startNewLogFile()
| | public void | unfreezePersistentStore()
|
| abortLogBackup | | public void abortLogBackup()(Code) | | |
| checkVersion | | public boolean checkVersion(int requiredMajorVersion, int requiredMinorVersion, String feature) throws StandardException(Code) | | Check to see if a database has been upgraded to the required
level in order to use a store feature.
This method is generally used to prevent writes to
data/log file by a particular store feature until the
database is upgraded to the required version.
In read-only database writes are not allowed, so nothing to do
for this method in this implementation of the log factory.
Parameters:
requiredMajorVersion - required database Engine major version
Parameters:
requiredMinorVersion - required database Engine minor version
Parameters:
feature - Non-null to throw an exception, null to return the state of the version match.
exception:
StandardException - not implemented exception is thrown |
| deleteLogFileAfterCheckpointLogFile | | public void deleteLogFileAfterCheckpointLogFile() throws StandardException(Code) | | |
| deleteOnlineArchivedLogFiles | | public void deleteOnlineArchivedLogFiles()(Code) | | |
| disableLogArchiveMode | | public void disableLogArchiveMode()(Code) | | |
| enableLogArchiveMode | | public void enableLogArchiveMode()(Code) | | |
| freezePersistentStore | | public void freezePersistentStore() throws StandardException(Code) | | Backup restore - stop sending log record to the log stream
exception:
StandardException - Standard Cloudscape error policy |
| getCanonicalLogPath | | public String getCanonicalLogPath()(Code) | | |
| getLogFactoryProperties | | public void getLogFactoryProperties(PersistentSet set)(Code) | | Get JBMS properties relavent to the log factory
|
| inRFR | | public boolean inRFR()(Code) | | |
| logArchived | | public boolean logArchived()(Code) | | Backup restore - is the log being archived to some directory?
if RawStore.LOG_ARCHIVAL_DIRECTORY is set to some value, that means the
log is meant to be archived. Else, log not archived.
|
| setDatabaseEncrypted | | public void setDatabaseEncrypted(boolean flushLog)(Code) | | |
| unfreezePersistentStore | | public void unfreezePersistentStore() throws StandardException(Code) | | Backup restore - start sending log record to the log stream
exception:
StandardException - Standard Cloudscape error policy |
