Introduction to oracle archive and non-archive Modes Oracle archive mode and non-archive Mode settings The log archiving mode of Oracle can effectively prevent instance and disk faults and is indispensable for database fault recovery. Because the initial installation mode of oracle is not the archive mode, therefore, you need to set it to archive mode. The following describes the methods and steps. Although simple, this is a necessary task for managin

Reprinted from: http://blog.csdn.net/leshami/article/details/5784713Oracle can save online log files to many different locations, and the process of converting online logs to archived logs is called archiving. The corresponding log is called the archive log.First, archive the logis a copy of the online redo log group file that contains the redo record and a unique log sequence number to archive one of the journal files in the log group, and if one of

When using ipve, rac hang is suspended due to the mistaken killing process, next, I will analyze the cause and provide a reference for the solution. If the customer feedback system hang is in place and cannot be archived, we need urgent intervention for analysis.Node 1 logWhen redo logs are not archived, the redo logs are fully written, and the alter system archive log current is manually executed, the database starts to ARCHIVE all the redo lo

database,The database reads the change element from the redo log and applies the change to the relevant data block.The database must contain at least two redo logs, one of which is always writable and used to record database changes,The other one is used for archiving (when the system's achievelog mode is enabled ).So how does Oracle record redo logs? The log writing process LGWR records redo logs.If the redo log file is full, LGWR writes the changed

logs are stored in the directory corresponding to the quick recovery zone (corresponding to the initialization parameter db_recovery_file_dest ). To change the location or name of an archived log file, modify the configuration parameters. 1. Configure the name format of the archive log fileThe initialization parameter log_archive_format sets the name format of the archive log. The Wildcards are as follows:% S: log serial number% S: log serial number (with leading 0)% T: Number of the redo threa

8.1 what is an archive log fileOracle databases allow you to store full redo log files to offline directories, which are called archive log files.Archive the process of saving the redo log file to the archive log file. This process can only run in an archived database. You can select manual or automatic archiving.It only reads one of the redo log file groups. When the database is running in archive mode, if the redo log file is not archived, The LGWR process cannot re-use this redo log. When aut

Whether the database is single-node or cluster, the way it carries things is strictly in the order of timestamps. This determinesWhen restoring a database, you must read the log records in strict chronological order to restore database files. Therefore, when the cluster database is restored,A complete log sequence is required.When the database is running in archive mode, logs are "partially" managed on the instance, so the archiving operation is also
