crash recovery

It is essential to have all the log files from the source database that were active at the time of the split to complete the crash recovery.

It has transactions (commit and rollback), supports multiple connections with transactional isolation, and provides crash recovery.

This method of logging ensures data consistency for all committed transactions so that crash recovery is possible.

Among the most noticeable new features are the much-improved crash recovery system.

As active logs are logs required for crash recovery, archive logs are logs that are active, but no longer required for crash recovery.

As standby and mirror options do not perform crash recovery, this does not apply to them.

You will find new information that was not part of the original article, including crash recovery and Cloudscape and . NET integration.

The engine provides transactions and crash recovery, and allows multiple connections and multiple threads to use a connection.

Recovery performance focuses primarily on crash recovery rather than on recovery after restoring a backup.

Archive logs are logs that are active and required for rollforward recovery but no longer needed for crash recovery.

In crash recovery, transactions that are not committed will be rolled back while committed data will be flushed to disk.

To enable this automatic crash recovery feature, verify that the database configuration parameter autorestart is set to ON.

Contains information about performance during crash recovery and about how to improve performance for recovering restored data.

In this case, no crash recovery will be performed unless this command was issued after a database crash.

The downside of a larger log buffer is that crash recovery can take slightly longer.

After the completion of the crash recovery, a new log chain will be started.

DB2 always performs crash recovery when the database is not shut down properly.

With the 11. 70 defragmenter, extents are merged while the partition is being read and updated, and full crash recovery is provided.

Active logs are logs that prevent lost of data during crash recovery such as power failure.

During the undo phase of a crash recovery, SQL Server 2005 lets users access the database.

On DB2 UDB, process failures such as a dead db2agent will cause a crash recovery.
