ERROR:

ORA-01804: failure to initialize timezone information

Cause

It is not able to find the TimeZone parameter  value in the specified path

[oracle@linx32  ~]$ echo $ORA_TZFILE
/u01/app/orad1i/db/tech_st/12.1.0.2/oracore/zoneinfo/timezlrg.dat

[oracle@linx32 ~]$ ls -ltr /u01/app/orad1i/db/tech_st/12.1.0.2/oracore/zoneinfo/timezlrg.dat

ls: cannot access /u01/app/orad1i/db/tech_st/12.1.0.2/oracore/zoneinfo/timezlrg.dat.: No such file or directory

Solution

Create a soft link to existing Time zone file

oracle@linx32 ~]$ cd /u01/app/orad1i/db/tech_st/12.1.0.2/oracore/zoneinfo

[oracle@linx32 ~] ln -s timezlrg_25.dat timezlrg.dat

[orad1i@nchlamsdb01 zoneinfo]$ ls -ltr timezlrg.dat

lrwxrwxrwx 1 oracle dba 11 Jun 11 10:24 timezlrg.dat -> timezlrg_25.dat

Re-run  Autoconfig, it shoud work.
