Carchivelogtxt

Carchivelogtxt is a term used in database administration to describe a plain-text representation of archived database redo logs. It is not a universal standard file type, but rather a convention adopted by some tools, scripts, or workflows to export metadata and references related to archived logs into a human-readable format.

typically, a carchivelogtxt file contains a sequence of text entries, each corresponding to an archived log event. Common fields found in these entries include the timestamp of archiving, the log sequence number, the thread or channel, the log’s start and end positions, the status, and a reference path or filename to the actual archived log. The exact field layout and separators can vary by tool, but the goal is to provide a concise, searchable record of archived logs without requiring binary log access.

Generation and usage: Carchivelogtxt is usually produced by archiving processes, log export utilities, or custom scripts that extract metadata from the system’s archived-log repository and write it to text. It serves several practical purposes, such as quick human inspection, auditing, troubleshooting, and integration with log analysis or monitoring systems. It can help DBAs verify that expected logs have been created, locate gaps, and support recovery planning.

Security and management: Because it can reveal sensitive operational details, access to carchivelogtxt files should be controlled, with appropriate retention and rotation policies.
