The contents of V$RMAN_BACKUP_JOB_DETAILS are summarized by a session connection to RMAN. The following query reports on the time taken for an RMAN backup per session. This query will display backup sets, the backup pieces with the set, and the data files that are backed up within the backup pieces: The output here has been shortened to fit on the page: Sometimes, its useful to report on the performance of RMAN backups. Are there any data files that have not been backed up recently.

Table 5-1 describes RMAN-related data dictionary views. Here are some other examples: The REPORT command may also be used for data files that have never been backed up or that may contain data created from a NOLOGGING operation. This command allows you to view backup sets, backup pieces, and the files included in the backup: The command shows all RMAN backups recorded in the repository. You need JavaScript enabled to view it. Description of RMAN Backup Data Dictionary Views, Backup status of online data files placed in backup mode (for hot backups), Data files backed up in backup sets, image copies, and proxy copies, Data files, control files, spfiles, and archive redo logs backed up. If you remain connected to RMAN while running multiple backup jobs, the query output reports on all backup activity while connected (for that session). There are several different methods for reporting on the RMAN environment: When first learning RMAN, the difference between the LIST and REPORT commands may seem confusing because the distinction between the two is not clear-cut. When running the script, youll need to pass in two variables: the Oracle SID and the threshold number of past days that you want to check for the last time the backups ran or for when a data file was backed up. You can enhance it as required for your RMAN environment. For example, say you have direct-path loaded data into a table, and the data file in which the table resides has not been backed up. You may want to spool the backups to an output file so that you can save the output and then use an OS editor to search through and look for specific strings in the output. For example, to check if backups have been running successfully within the past 2 days, run the script (named rman_chk.bsh): The prior script is basic but effective. 2018-03-03 - RMAN Recipes for Oracle Database 12c, 2018-07-14 - Desirable Functionality in Web-Based OLAP Reporting, 2018-05-02 - Using Oracle Essbase Studio powerful features, -0001-11-30 - Restore Oracle Database 12c from an RMAN Backup.

You should have an automated method of detecting whether or not RMAN backups are running and if data files are being backed up. You can quickly view all the data files associated with a database, as follows: The REPORT command provides detailed information about backups marked obsolete via the RMAN retention policy; for example. The RMAN REPORT command is useful for reporting on a variety of details. You can report on data files that need to be backed up, as defined by the retention policy, like this: There are several ways to report on data files that need to be backed up. Therefore, the report output is more accurate if you connect to RMAN (establishing a session) and then exit out of RMAN after the backup job is complete. In general, I use the LIST command to view information about existing backups and the REPORT command to determine which files need to be backed or to display information on obsolete or expired backups. For example, Ill generally implement an automated check via a shell script and SQL that reports whether the RMAN backups have run within the last day. Sometimes, DBAs new to RMAN have a hard time grasping the concept of backups, backup sets, backup pieces, and data files and how they relate.

I use SQL queries for specialized reports (not available via LIST or REPORT) or for automating reports. Table 5-1. One reliable method of automating such a task is to embed SQL into a shell script and then run the script on a periodic basis from a scheduling utility such as cron. Youll need to modify the script and provide it with a username and password for a user that can query the data dictionary objects referenced in the script and also change the e-mail address of where messages are sent. When investigating issues with RMAN backups, usually one of the first tasks I undertake is connecting to the target database and running the LIST BACKUP command. I find the following query useful when discussing RMAN backup components. These views are available regardless of your use of a recovery catalog (the information in these views is derived from the control file). -. To get a summarized view of backup information, use the LIST BACKUP SUMMARY command: You can also use the LIST command to report just image copy information: To list all files that have been backed up, and the associated backup set, issue the following command: These commands display archive redo logs on disk: And, this command lists the backups of the archive redo logs (and which archive redo logs are contained in which backup pieces): There are a great many ways in which you can run the LIST command (and, likewise, the REPORT command, covered in the next section). The prior methods are the ones youll run most of the time. Publish modules to the "offcanvas" position.
