One of the trainee from our previous batch, encountered  issue “ORA-01804: failure to initialize timezone information” in Post Database upgrade  step while running AutoConfig.

Note: There are total 9 stages in 12.2 Upgrade where database upgrade to 11gR2 or 12c is one of the step.


1. Running Autoconfig on Database tier as

$ORACLE_HOME>/appsutil/bin/adconfig.sh contextfile=$ORACLE_HOME/appsutil/PROD1211_iamdemo01.xml


Error messages in AutoConfig logs: /u01/oracle/PROD1211_11204/db/tech_st/11.2.0/appsutil/log/


SQLPLUS Executable : /u01/oracle/PROD1211_11204/db/tech_st/11.2.0/bin/sqlplus

ORA-01804: failure to initialize timezone information

SP2-0152: ORACLE may not be functioning properly
adcrobj.sh exiting with status 1


Apply patch 7651166 (as per ReadMe instructions ) to fix the above issue and run AutoConfig again as

$ORACLE_HOME/ appsutil/ bin/ adconfig.sh contextfile=$ORACLE_HOME/ appsutil/PROD1211_iamdemo01.xml

You should see a message “AutoConfig Completed Successfully”
