ADRCI command tips!

Oracle 11g New Features Tips by Donald BurlesonJune 29, 2015

Oracle Automatic Diagnostic Repository (ADR) commands are with the Oracle Incident Packaging Services (IPS) to report issues to Oracle technical support (MOSC).

See these notes on using ADRCI with IPS Incident packaging services.

From the command prompt, the ADRCI utility is entered by typing:

C:\>adrci

ADRCI: Release 11.1.0.6.0 - Beta on Thu Nov 15 22:21:42 2015

ADR base = "file:///u01/oracle/11g">u01/oracle/11g"

adrci>

You can also display ADR information from the v$diag_info view:

SQL> SELECT name, value FROM v$diag_info;

NAME VALUE
--------------------- ---------------------------------------------------
Diag Enabled          TRUE
ADR Base              /u01/app/oracle
ADR Home              /u01/app/oracle/diag/rdbms/db11/db1
Diag Trace            /u01/app/oracle/diag/rdbms/db11/db1/trace
Diag Alert            /u01opt/app/oracle/diag/rdbms/db11/db1/alert
Diag Incident         /u01/app/oracle/diag/rdbms/db11/db1/incident
Diag Cdump            /u01/app/oracle/diag/rdbms/db11/db1/cdump
Health Monitor        /u01/app/oracle/diag/rdbms/db11/db1/hm
Default Trace File    /u01/app/oracle/diag/rdbms/db11/db1/trc/ora_9230.trc
Active Problem Count 0
Active Incident Count 0

ADRCI Homes

ADRCI commands are based on one or more base directories known as ADR homes. Before using the ADRCI commands, it is helpful to set an active ADR home to work with a single instance. The available homes can be seen by typing:

adrci> show homes

ADR Homes:
diag\clients\user_system\host_1475088825_11
diag\clients\user_varun jain\host_1475088825_11
diag\rdbms\ora11g4\ora11g4
diag\rdbms\ora11gr1\ora11gr1
diag\tnslsnr\dcfx7hb1\listener
adrci>

The output above shows that there are several available home directories on which ADR can operate. If a DBA wants to only access diagnostic data from one of the available homes, the active ADR home should be set appropriately. The active home can be set using the set homepath command:

adrci> set homepath diag\rdbms\ora11gr1\ora11gr1

adrci> show homes

ADR Homes:
diag\rdbms\ora11gr1\ora11gr1

adrci>

The output demonstrates that after setting the active ADR home, only the active home displays.

ADRCI alert log commands

You can run the ADRCI "show alert" command to view the alert log:

adrci> set homepath diag/rdbms/ora11gr1\ora11gr

adrci> show alert -tail;

Note: Rampant author Laurent Schneider has some additional insight into creating an Oracle Automatic Diagnostic Repository (ADR).
