ADRCI is a command-line tool that is part of the fault diagnosability infrastructure introduced in Oracle Database 11g. ADRCI enables you to:
View diagnostic data within the Automatic Diagnostic Repository (ADR).
View Health Monitor reports.
Package incident and problem information into a zip file for transmission to Oracle Support.
Diagnostic data includes incident and problem descriptions, trace files, dumps, health monitor reports, alert log entries, and more.
ADR data is secured by operating system permissions on the ADR directories, hence there is no need to log in to ADRCI.
ADRCI has a rich command set, and can be used in interactive mode or within scripts.
The easier and recommended way to manage diagnostic data is with the Oracle Enterprise Manager Support Workbench (Support Workbench). ADRCI provides a command-line alternative to most of the functionality of the Support Workbench, and adds capabilities such as listing and querying trace files.
See Oracle Database Administrator's Guide for complete information about the Support Workbench.
