ORA-30013: undo tablespace currently in use故障处理思路

发布时间:2020-06-23 12:30:25 来源:网络 阅读:2960 作者:yangjunfeng 栏目:关系型数据库

当日早上,某系统数仓数据库告警,数据库版本为12c,操作系统为RHEL7.2

尝试了一些手段,但是库无法启动,我们都知道,RAC系统正常情况是DB1使用untbs1,DB2使用untbs2。登陆系统查看也都正常。

无奈提交SR寻找后线支持,Oracle工程师反馈查询:
select a.SID,a.NAME,a.VALUE$,b.PDB_NAME
from
sys.pdb_spfile$ a,cdb_pdbs b
where a.PDB_UID=b.CON_UID;
15:21:33 > col PDB_NAME for a20
15:21:42 > /

SR继续反馈Please use following commands:

ALTER SESSION SET CONTAINER =DCDB;
ALTER SYSTEM SET undo_tablespace=UNDOTBS1 scope=spfile sid='dwdb1';
ALTER SYSTEM SET undo_tablespace=UNDOTBS2 scope=spfile sid='dwdb2';
alter pluggable database DCDB open;

我们在查询一下:
16:56:08 > select a.SID,a.NAME,a.VALUE$,b.PDB_NAME
16:56:09 2 from
16:56:09 3 sys.pdb_spfile$ a,cdb_pdbs b
16:56:09 4 where a.PDB_UID=b.CON_UID;

  • undo_tablespace 'UNDOTBS1' DWDBPDB
    DWDB1 undo_tablespace 'UNDOTBS1' DWDBPDB
    DWDB2 undo_tablespace 'UNDOTBS2' DWDBPDB
    dwdb1 undo_tablespace 'UNDOTBS1' DWDBPDB

  • db_securefile 'PREFERRED' DCDB

    dwdb1 undo_tablespace 'UNDOTBS1' DCDB
    dwdb2 undo_tablespace 'UNDOTBS2' DCDB

这里有个坑,需要我们指定对SID为正确的PDB,这里有个乌龙,Oracle SR后台工程师让此之前有错误建议:

ALTER SESSION SET CONTAINER =DCDB;
ALTER SYSTEM SET undo_tablespace=UNDOTBS1 scope=spfile sid='dcdb1';
ALTER SYSTEM SET undo_tablespace=UNDOTBS2 scope=spfile sid='dcdb2';
alter pluggable database DCDB open;

The difference is that:

2018-08-23T15:53:13.142757+08:00
DCDB(3):ALTER SYSTEM SET undo_tablespace='UNDOTBS1' SCOPE=SPFILE SID='dcdb1' PDB='DCDB'; ---错误
《==DCDB(3): this command is executed in pdb DCDB

2018-08-23T11:07:37.996006+08:00
ALTER SYSTEM SET undo_tablespace='UNDOTBS1' SCOPE=BOTH SID='dwdb1'; --正确

<=======this command is executed in cdb.

好记性不如烂笔头,特此记录一下12c的那些坑~

向AI问一下细节
