truncate table 无论drop storage还是reuse storage不影响数据恢复

今天有朋友咨询,truncate table有drop storage和reuse storage方式,是否影响后续的数据恢复(在没有其他覆盖的情况下),我做了一个简单的测试证明,这些都不影响truncate table的数据库恢复
创建测试环境

SQL> create table t_xifenfei tablespace USERNEW
  2   as select * from dba_objects;

Table created.

SQL> create table t_xifenfei2  tablespace USERNEW
  2   as select * from dba_objects;

Table created.

SQL>  create table t_xifenfei3  tablespace USERNEW
  2  as select * from dba_objects;

Table created.

SQL> alter system checkpoint;

System altered.

SQL> select count(*) from t_xifenfei;

  COUNT(*)
----------
     86348

SQL>  select count(*) from t_xifenfei2;

  COUNT(*)
----------
     86349

SQL>  select count(*) from t_xifenfei3;

  COUNT(*)
----------
     86350

SQL> select object_id,data_object_id,object_name from dba_objects where object_name like 't_xifenfei%';

 OBJECT_ID DATA_OBJECT_ID OBJECT_NAME
---------- -------------- ------------------------------
     88205          88205 t_xifenfei
     88206          88206 t_xifenfei2
     88207          88207 t_xifenfei3

SQL> truncate table t_xifenfei;

Table truncated.

SQL> truncate table t_xifenfei2 drop storage;

Table truncated.

SQL> truncate table t_xifenfei3 reuse storage;

Table truncated.

使用dul进行恢复

  
DUL>  bootstrap;
DUL> scan database;

scanning database...
scanning database finished.

DUL> unload table sys.t_xifenfei object 88205;

Unloading table: t_xifenfei,object ID: 88205
Unloading segment,storage(Obj#=88205 DataObj#=88205 TS#=6 File#=5 Block#=1410 Cluster=0)
86348 rows unloaded

DUL> unload table sys.t_xifenfei2 object 88206;

Unloading table: t_xifenfei2,object ID: 88206
Unloading segment,storage(Obj#=88206 DataObj#=88206 TS#=6 File#=5 Block#=2690 Cluster=0)
86349 rows unloaded

Unloading table: t_xifenfei3,object ID: 88207
Unloading segment,storage(Obj#=88207 DataObj#=88207 TS#=6 File#=5 Block#=3970 Cluster=0)
86350 rows unloaded

这里证明truncate table不管是drop storage还是reuse storage或者默认,在没有被覆盖的情况下,数据均完全恢复出来

   ** Note that multiple ports can use the same internal error numbers.
      We allow this because we don't want to waste numbers on port internal
      errors, something which is very rarely used.  In addition it is
      likely that any bug that is reporting a port internal error to the
      generic (portable) coding group is going to have to supply a lot of
      documentation - so if two ports use the same number, it should never
      confuse anybody.

Oracle dul支持18c

在以前的文章中已经写过oracle 原厂dul工具可以很好的支持oracle 11g,12c(Oracle dul支持Oracle 12.2(12c),dul 10支持oracle 11g r2),现在确认通过一些处理,dul也可以完美支持oracle 18c
数据库版本18c

BUG:24844841 – PHSB:CDB M000 REPORTED ORA-1110 ON ADG WHEN A DATAFILE IS ADDED ON PRIMARY
@ The M000 messages is a false alarm as well. It is a false alarm by DRA check
@ that doesn’t consider standby media recovery properly. Adding a file happens
@ to trigger the timing for the false alarm.
@ One way to fix this is to skip file header check if standby recovery is
@ running inside kcidr_file_header_all_check_common.
M000进程检查数据库文件头信息,由于bug原因报ORA-01110错误.

处理建议
1.打上补丁24844841
2.19.1版本修复该问题
3.重启备库,启动mgr
4.暂时忽略该问题(目前没有发现影响数据库同步)
参考:ORA-01110 For All Files In Standby Database (Doc ID 2322290.1)
