General Streams Related Views

Figure 7.3 shows the general Streams related views in a single glance.

Figure 7.3 General Streams Related static and dynamic views

 

The description of each of the view follows:

v$archived_log

This view shows the archived log file details. It shows the names of the log files, and the start and end SCN values. Whenever a Capture process halted for any valid reason, on resumption it still must go back to archive log files to scan the redo entries. It is important to keep track of the archive log files location and monitor the removal of the archived log files from the file system. If the archived logs are removed before the Capture process has completed its scan, the Capture process will abort. Failing to have right archive log will abort the Capture process.
