前言

Oracle19C通过dump方式从TSTZ version 38 导入到低版本TSTZ version 32时报ORA-39405，本博客做了详细的处理过程说明。

---

📣 1.故障案例

ORA-39405: Oracle Data Pump does not support importing from a source database with TSTZ version 38 into a target database with TSTZ version 32.

--目标库
SQL> SELECT * FROM v$timezone_file;
FILENAME                VERSION     CON_ID
-------------------- ---------- ----------
timezlrg_32.dat              32          0

--源库
SQL> SELECT * FROM v$timezone_file;
FILENAME                VERSION     CON_ID
-------------------- ---------- ----------
timezlrg_38.dat              38          0

SELECT DBMS_DST.get_latest_timezone_version FROM dual;

综合以上报错及官方的案例，特对本次故障进行如下的处理，需要对原库进行补丁的升级

📣 2.补丁下载

下载最新的 OPatch 和 DSTV38 更新补丁

Opatch Version Patch:
https://updates.oracle.com/download/6880880.html

DST V38 Patch:
https://updates.oracle.com/download/34006614.html

📣 3.升级Opatch版本

[root@dbhost ~]# cd /opt
[root@dbhost opt]# chown oracle:oinstall -R p6880880_190000_Linux-x86-64.zip
[root@dbhost opt]# chmod 755 -R p6880880_190000_Linux-x86-64.zip

--备份原来的OPatch
[root@dbhost ~]# su - oracle
Last login: Sun Aug 20 13:09:38 CST 2023 on pts/0
[oracle@dbhost ~]$ cd $ORACLE_HOME/
[oracle@dbhost dbhome_1]$ mv OPatch OPatch_bak

--应用新的补丁
unzip /opt/p6880880_190000_Linux-x86-64.zip -d $ORACLE_HOME
[oracle@dbhost ~]$ cd $ORACLE_HOME/OPatch
[oracle@dbhost OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.28
OPatch succeeded.

📣 4.检查Patch 是否冲突

[root@dbhost opt]# chown oracle:oinstall -R p34006614_190000_Linux-x86-64.zip
[root@dbhost opt]# chmod 755 -R p34006614_190000_Linux-x86-64.zip

[oracle@dbhost ~]$ unzip /opt/p34006614_190000_Linux-x86-64.zip -d /opt
[oracle@dbhost ~]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph /opt/34006614

📣 5.应用补丁34006614

[oracle@dbhost ~]$ cd /opt/34006614/
[oracle@dbhost 34006614]$ $ORACLE_HOME/OPatch/opatch apply -oh $ORACLE_HOME

📣 7.升级TZ

注意：先关闭数据库和监听哈
[oracle@dbhost ~]$ lsnrctl stop
[oracle@dbhost ~]$ sqlplus / as sysdba
SQL> shutdown immediate

✨ 7.1 Upgrade mode下启动数据库

SQL> STARTUP UPGRADE;

SQL> select name, open_mode from v$database;
NAME      OPEN_MODE
--------- --------------------
ORCL      READ WRITE
SQL> select instance_name, status from v$instance;
INSTANCE_NAME    STATUS
---------------- ------------
orcl             OPEN MIGRATE

✨ 7.2 升级前准备

SQL> DECLARE
l_tz_version PLS_INTEGER;
BEGIN
l_tz_version := DBMS_DST.get_latest_timezone_version;
DBMS_OUTPUT.put_line(‘l_tz_version=’ || l_tz_version);
DBMS_DST.begin_prepare(l_tz_version);
END;
/

SQL> COLUMN property_name FORMAT A30

SELECT property_name, property_value
FROM   database_properties
WHERE  property_name LIKE 'DST_%'
ORDER BY property_name;

PROPERTY_NAME                  PROPERTY_VALUE
------------------------------ --------------------
DST_PRIMARY_TT_VERSION         32
DST_SECONDARY_TT_VERSION       38
DST_UPGRADE_STATE              PREPARE

✨ 7.3 查找受影响的表

SQL> EXEC DBMS_DST.find_affected_tables;

PL/SQL procedure successfully completed.

SQL> select count(*) from sys.dst$affected_tables;

  COUNT(*)
----------
         0
结束升级前准备
SQL> EXEC DBMS_DST.end_prepare;
PL/SQL procedure successfully completed.

✨ 7.4 开始升级TZ

SQL> shutdown immediate;
SQL> startup upgrade;

SQL> SET SERVEROUTPUT ON
DECLARE
  l_tz_version PLS_INTEGER;
BEGIN
  SELECT DBMS_DST.get_latest_timezone_version
  INTO   l_tz_version
  FROM   dual;

  DBMS_OUTPUT.put_line('l_tz_version=' || l_tz_version);
  DBMS_DST.begin_upgrade(l_tz_version);
END;
/

✨ 7.5 关闭升级模式

SQL> shut immediate;
SQL> startup;

SQL> SET SERVEROUTPUT ON

DECLARE
  l_failures   PLS_INTEGER;
BEGIN
  DBMS_DST.upgrade_database(l_failures);
  DBMS_OUTPUT.put_line('DBMS_DST.upgrade_database : l_failures=' || l_failures);
  DBMS_DST.end_upgrade(l_failures);
  DBMS_OUTPUT.put_line('DBMS_DST.end_upgrade : l_failures=' || l_failures);
END;
/

📣 8.查看升级结果

SQL> SELECT property_name, property_value
FROM database_properties
WHERE property_name LIKE ‘DST_%’
ORDER BY property_name;

PROPERTY_NAME                  PROPERTY_VALUE
------------------------------ --------------------
DST_PRIMARY_TT_VERSION         38
DST_SECONDARY_TT_VERSION       0
DST_UPGRADE_STATE              NONE
