AutoConfig is exiting with status 2

Cause:
SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE may not be functioning properly

Solution:

The issue is related to ORA_TZFILE env variable in 11GR2 this env variable is no longer needed.

In Oracle Database server to fix this issue Unset the env varaible ORA_TZFILE and try to connect.

In Oracle Applications Database to fix this issue Perform the below.

The ORA_TZFILE is set while at 11gR2 this should not be set.

The  $ORACLE_HOME/appsutil/template/ad8idbux.env is from the wrong version  (ad8idbux.env 120.8)

The wrong file includes the  following:

ORA_TZFILE="$ORACLE_HOME/oracore/zoneinfo/timezlrg.dat"

export  ORA_TZFILE

While for 11gr2 it should be:

if test "%s_database%" =  "db112" ;  then

ORA_TZFILE=""

else

ORA_TZFILE="$ORACLE_HOME/oracore/zoneinfo/timezlrg.dat"

fi

export  ORA_TZFILE

Source the environment variable and executed autoconfig in Database Node, completed without issue

on your DB Tier:

cd $ORACLE_HOME/oracore/zoneinfo

ln -s timezone_14.dat timezone.dat

ln -s timezlrg_14.dat timezlrg.dat

*where 14 is the DST version you have upgraded to post 11gR2 upgrade.
