The Temporary directory for XML Publisher has not been modified after making the clone so it was pointing to non existing location and getting error out.

Solution

2. Make sure that the application owner (APPLMGR) has Read and Write permission this directory.

Cause:
Issue is due to Password_verify_function enables in dba_profiles for APPS,APPLSYS,APPS_NE users

Solution:

Disable the password verify function for APPS,APPLSYS,APPS_NE users in database profiles.
1. Identify the database profile for APPS,APPLSYS,APPS_NE users using below query.

SELECT USERNAME,PROFILE FROM DBA_USERS where USERNAME in ('APPS','APPLSYS','APPS_NE');
SELECT PROFILE,VALUE FROM DBA_PROFILES WHERE  PROFILE='&profile for user';

2. Disable password verify function

alter profile <profile_name> limit PASSWORD_VERIFY_FUNCTION null;

3. Run the FNDCPASS command to change password.

FNDCPASS apps/<apps_pwd> 0 Y system/<password> SYSTEM APPLSYS <new_apps_password>

4. After changing apps password, run autoconfig on Middle tier and update EBS datasource for R12.2.x
