Time zone issues while upgrading the database from 11.2.0.4 to 19c:-

Solving DST_UPGRADE_STATE in PREPARE

if DST_UPGRADE_STATE is "PREPARE" then issue:-

-- PROPERTY_NAME                              VALUE
-- ------------------------------  ------------------------------
-- DST_PRIMARY_TT_VERSION                32
-- DST_SECONDARY_TT_VERSION          0 
-- DST_UPGRADE_STATE                            PREPARE

CONN / as sysdba

EXEC DBMS_DST.END_PREPARE;

check that DST_UPGRADE_STATE is now NONE:-

SELECT PROPERTY_NAME, SUBSTR(property_value, 1, 30) value
FROM DATABASE_PROPERTIES
WHERE PROPERTY_NAME LIKE 'DST_%'
ORDER BY PROPERTY_NAME;

-- PROPERTY_NAME                              VALUE
-- ------------------------------  ------------------------------
-- DST_PRIMARY_TT_VERSION                32
-- DST_SECONDARY_TT_VERSION          0 
-- DST_UPGRADE_STATE                            NONE
