获取表空间是否可自动扩展的SQL

Posted on 2012/02/21 by yangtingkun

好长时间没写SQL了，今天看到同事在使用一个检查表空间是否可自动扩展的SQL，不但效率不高，而且非常的累赘，忍不住自己写了一个。 原始SQL如下： SQL> SELECT DISTINCT tablespace_name, autoextensible 2 FROM DBA_DATA_FILES 3 WHERE autoextensible = ‘YES’ 4 UNION 5 SELECT DISTINCT tablespace_name, autoextensible 6 FROM DBA_DATA_FILES 7 WHERE autoextensible = ‘NO’ 8 AND tablespace_name NOT IN 9 (SELECT DISTINCT tablespace_name 10 … Continue reading →

ORA-600(kgeade_is_0)错误

Posted on 2012/02/20 by yangtingkun

一个和并行执行有关的bug。 虽然是并行执行相关，但是报错的并不是Pnnn进程，事实上，实在RAC环境中查询GV$表导致了这个错误。 Wed May 04 15:56:02 EAT 2011 Starting ORACLE instance (normal) LICENSE_MAX_SESSION = 0 LICENSE_SESSIONS_WARNING = 0 Interface TYPE 1 lan900 192.168.194.0 configured FROM OCR FOR USE AS a cluster interconnect Interface TYPE 1 lan901 10.142.194.0 configured FROM OCR … Continue reading →

Posted on 2012/02/18 by yangtingkun

客户告警日志出现ORA-600[kjzhablar:idx]错误，已经碰到过ORA-7445[kjzhablar:idx]的错误，虽然错误函数相同，但是二者关系不大。 错误信息为： Sat May 14 18:54:55 EAT 2011 Errors IN file /oracle/app/admin/orcl/bdump/orcl1_diag_3889.trc: ORA-00600: internal error code, arguments: [kjzhablar:idx], [1], [1], [0x9FFFFFFFFD343AB4], [], [], [], [] Sat May 14 18:54:57 EAT 2011 Trace dumping IS performing id=[cdmp_20110514185457]Sat May 14 18:54:55 EAT … Continue reading →

EXCHANGE分区导致主键重复

Posted on 2012/02/15 by yangtingkun

分区表的EXCHANGE交换分区不检查数据有效性，可能导致LOCAL主键索引出现重复值。 通过一个简单的例子来说明这个问题： SQL> CREATE TABLE T_PART_EXCHANGE (ID NUMBER, NAME VARCHAR2(30), TYPE VARCHAR2(18)) 2 PARTITION BY LIST (TYPE) 3 (PARTITION P1 VALUES (’TABLE’), 4 PARTITION P2 VALUES (DEFAULT)); TABLE created. SQL> CREATE INDEX IND_PART_EXCHANGE_TYPEID ON T_PART_EXCHANGE(TYPE, ID) LOCAL; INDEX created. SQL> … Continue reading →

语句级并行提示

Posted on 2012/02/14 by yangtingkun

最近才发现并行提示增加了语句级并行的功能。 以前添加并行都是对指定的表添加，最近才发现，如果不加表名，是指定这个语句的并行度： SQL> CREATE TABLE t_p_i AS 2 SELECT * 3 FROM dba_objects 4 WHERE 1 = 2; TABLE created. SQL> CREATE TABLE t_p_s AS 2 SELECT * 3 FROM dba_objects; TABLE created. SQL> SET autot ON EXP SQL> INSERT … Continue reading →

STATSPACK报告REDO SIZE出现负值

Posted on 2012/02/12 by yangtingkun

客户9.2.0.8数据库的STATSPACK报告出现负的REDO SIZE。 类似信息如下： LOAD Profile ~~~~~~~~~~~~ Per SECOND Per TRANSACTION ————— ————— Redo SIZE: -263,339.94 -685,483.59Load Profile ~~~~~~~~~~~~ Per Second Per Transaction ————— ————— Redo size: -263,339.94 -685,483.59 其实经常出现的还包括逻辑读以及物理读等。其实不查询MOS也可以确定，这是Oracle的bug，而导致bug的原因应该是底层的C代码中没有使用UNSIGNED类型，以至于变量溢出后出现了负值。 在MOS中的对应描述为：Redo Size Negative In Statspack Report [ID 308414.1]，Oracle在10g中解决了这个问题。确认影响版本从8.1.7.4到9.2.0.8。
