Recovery data

The aim of this project is to provide a summary of the current knowledge on energy recovery options from wastewater treatment plants sludge and/or biosolids. This covers technologies as well as data from case studies and research experimental results. The focus of the study is the ATP. The project methodology comprised two stages. The first stage involved a review of the current literature.

This provides fifty times the observations for each business cycle allowing for much more robust statistical results. The state-level data, along with the newly developed jobless recovery measure from chapter one, is used to test several of the existing hypotheses on the causes of jobless recoveries.

The main purpose of this study is to better understand the U.S economy recovery in order to know if the recent crisis will be followed by another one much bigger or if the United States will be fully recovered. Through this study, it will examine the current strengths and weaknesses of the U.S economy. This work is based on two sources, primary data and secondary data. The primary data has been collected by three deep interviews and one questionnaire whereas the secondary data have been selected from several sources such as articles, books, libraries, Internet.

Using Online Redo Log Files Online redo log files provide the means to redo transactions in the event of a database failure. Every transaction is written synchronously to the Redo Log Buffer, then gets flushed to the online redo log files in order to provide a recovery mechanism in case of media failure. (With exceptions such as direct load inserts in objects with the NOLOGGING clause enabled.) This includes transactions that have not yet been committed, undo segment information, and schema and object management statements.

Overview The recovery catalog is a schema that is created in a separate database. It contains the RMAN metadata obtained from the target database control file. RMAN propagates information about the database structure, archived redo logs, backup sets, and datafile copies into the recovery catalog from the control file of the target database. You should use a catalog when you have multiple target databases to manage. RMAN stores, uses, and maintains the information in the recovery catalog. The recovery catalog is maintained by RMAN when you do the following: 1.

Workshop Methodology Group-Oriented and Interactive Structure The workshop is structured to allow individuals to work in groups to perform database backup, restore, and recovery operations. Each group is encouraged to share its approach to resolving database failures with other groups in the class. Intensive Hands-On Diagnosis and Problem Resolution The intent is to provide you with as much hands-on experience as possible to diagnose and work through backup and recovery scenarios.

Incomplete Recovery Incomplete recovery reconstructs the database to a prior point in time (before the time of the failure). Note: This situation results in the loss of data from transactions committed after the time of recovery. This data will need to be reentered manually if required. Perform this recovery only when absolutely necessary. Incomplete recovery can be a difficult and time-consuming operation.

Using Oracle Enterprise Manager You can use the Recovery Wizard to restore and recover your database. On the Range Selection page you must enter a date and time to restore to a previous point. You use Instance Management or the Console to open the database after the job has completed. You can view the status of the job by selecting the Active and History page tabs in the Console’s Job window.

Restoration and Datafile Media Recovery Using RMAN RMAN automates the procedure for restoring files. When you issue the RESTORE command, RMAN uses a server session to restore the correct backups and copies. The RMAN repository is used to select the best available backup set or image copies to use in the restoration. By default, RMAN does not restore a file if the file is already in the correct place and its header contains the correct information. In releases before Oracle9i, the files were always restored.

Media Recovery Media recovery is used to recover a lost or damaged current datafile or control file. You can also use it to recover changes that were lost when a datafile went offline without the OFFLINE NORMAL option. Restoring Files When you restore a file, you are replacing a missing or damaged file with a backup copy. Recovery of Files When you recover a file, changes recorded in the redo log files are applied to the restored files.

Types of Recovery Manager Backups Recovery Manager provides functionality to back up: The entire database, every datafile in a tablespace, or a single datafile The control file All or selected archived logs Note: The online redo log files are not backed up when using Recovery Manager. Closed Database Backups A closed database backup is defined as a backup of the database while it is closed (offline). This is the same as the consistent database backup. If you are performing a closed backup, the target database must not be open.

Backup Terminology Whole Database Backup Whole database backup (also known as whole backup) refers to a backup of all datafiles and the control file of the database. Whole backups can be performed when the database is closed or open. This is the most common method of backup. The whole backup that is taken when the database is closed (after the database is shut down using the NORMAL, IMMEDIATE, or TRANSACTIONAL options) is called a consistent backup.

Recovery Manager Features Recovery Manager (RMAN) is an Oracle utility that you use to manage the backup, restore, and recovery operations on Oracle databases. RMAN has a powerful command language that is independent of the operating system. Recovery Manager has a command-line interface. Oracle Enterprise Manager also provides a graphical user interface for the Recovery Manager. Recovery Manager can be used on databases of Oracle8 or later releases. RMAN provides several features not available when you make user-managed backups with operating system commands.

Overview The Oracle server uses many memory components, background processes, and file structures for its backup and recovery mechanism. This lesson reviews the concepts presented in the Oracle9i Database Administration Fundamentals I course, with an emphasis on backup and recovery requirements. Oracle Instance An Oracle instance consists of memory areas (mainly System Global Area [SGA]) and background processes, namely PMON, SMON, DBWn, LGWR, and CKPT. An instance is created during the nomount stage of the database startup after the parameter file has been read.
