2、查看trace文件

3、日志初步结论
通过alert日志，感觉应该是对分区表操作，导致”VAS”.”XN_CALLLOG_ANALYSIS_PK”索引变成了unusable state，然后在数据库自动收集统计信息的时候报错(最大可能是全局index导致)

4、验证猜测是否正确

SQL> SELECT owner,index_name,table_name,status FROM DBA_indexes 
   2 WHERE index_name='XN_CALLLOG_ANALYSIS_PK' AND owner='VAS';
 
OWNER                          INDEX_NAME                     TABLE_NAME                     STATUS
------------------------------ ------------------------------ ------------------------------ --------
VAS                            XN_CALLLOG_ANALYSIS_PK         TAB_XN_CALLLOG_ANALYSIS        UNUSABLE

5、解决相关问题问题

SELECT 'ALTER INDEX ' || INDEX_OWNER || '.' || INDEX_NAME ||
'REBUILD PARTITION ' || PARTITION_NAME || ' NOLOGGING online;'
FROM DBA_IND_PARTITIONS
WHERE INDEX_OWNER NOT IN ('SYS', 'SYSTEM', 'PUBLIC')
AND STATUS = 'UNUSABLE'
UNION ALL
SELECT 'alter index ' ||OWNER || '.' || A.INDEX_NAME || ' REBUILD online nologging;'
FROM DBA_INDEXES A
WHERE OWNER NOT IN ('SYS', 'SYSTEM', 'PUBLIC')
AND STATUS = 'UNUSABLE';

执行生成sql，解决相关index unusable问题

V$PWFILE_USERS和密码文件关系

发表于 2011 年 12 月 4 日由惜分飞

一、V$PWFILE_USERS定义

V$PWFILE_USERS lists all users in the password file, and indicates whether the user has been granted the SYSDBA, SYSOPER, and SYSASM privileges.
Column	    Datatype	Description
USERNAM    VARCHAR2(30)	Name of the user that is contained in the password file
SYSDBA	   VARCHAR2(5)	Indicates whether the user can connect with SYSDBA privileges (TRUE) or not (FALSE)
SYSOPER	   VARCHAR2(5)	Indicates whether the user can connect with SYSOPER privileges (TRUE) or not (FALSE)
SYSASM	   VARCHAR2(5)	Indicates whether the user can connect with SYSASM privileges (TRUE) or not (FALSE)

二、v$pwfile_users与密码文件关系

1、如果密码文件不存在或者名称错误，查询v$pwfile_users将得到空记录
2、添加sysdba等权限用户，会记录到密码文件和v$pwfile_users中
3、到回收sysdba等权限用户，密码文件记录依然存在，但是v$pwfile_users中无对应记录

三、远程登录测试

--密码文件记录存在，视图不记录不存在，登录失败
[oracle@node1 ~]$ sqlplus xff01/xifenfei@ora11g as sysdba

SQL*Plus: Release 10.2.0.5.0 - Production on Sun Dec 4 19:42:26 2011

Copyright (c) 1982, 2010, Oracle.  All Rights Reserved.

ERROR:
ORA-01031: insufficient privileges


Enter user-name

--密码文件视图记录均存在，登录成功
[oracle@node1 ~]$ sqlplus sys/xifenfei@ora11g as sysdba

SQL*Plus: Release 10.2.0.5.0 - Production on Sun Dec 4 19:42:10 2011

Copyright (c) 1982, 2010, Oracle.  All Rights Reserved.

Connected to an idle instance.

是否能远程登录，依照v$pwfile_users为准

四、创建密码文件

win：
orapwd file=%ORACLE_HOME%\database\PWD%ORACLE_SID%.ora entries=3 password=manager force=y
linux:
orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID entries=3 password=manager force=y

ORA-1502问题分析解决

发表于 2011 年 12 月 2 日由惜分飞

1、出现ORA-1502
接到开发报告，我们报表程序出现SQLCODE=[-1502]错误提示，sql执行不成功，根据这个提示，我猜想是ORA-1502错误，查询ora-1502错误

[oracle@node1 ~]$ oerr ora 1502
01502, 00000, "index '%s.%s' or partition of such index is in unusable state"
// MERGE: 1489 RENUMBERED TO 1502
// *Cause: An attempt has been made to access an index or index partition
//         that has been marked unusable by a direct load or by a DDL
//         operation
// *Action: DROP the specified index, or REBUILD the specified index, or
//         REBUILD the unusable index partition

根据这个提示，错误的原因是因为有index编程unusable state

--查询分区index是否有UNUSABLE的index
SQL> col index_owner for a20
SQL> col index_name for a30
SQL> col partition_name for a20    
SQL>  SELECT INDEX_OWNER, INDEX_NAME, PARTITION_NAME
  2     FROM DBA_IND_PARTITIONS
  3    WHERE INDEX_OWNER NOT IN ('SYS', 'SYSTEM', 'PUBLIC')
  4     AND STATUS = 'UNUSABLE';

INDEX_OWNER          INDEX_NAME                     PARTITION_NAME
-------------------- ------------------------------ --------------------
STAT_YDZJ            IND_STAT_DAY_COMPANY_DAY        P_201111
STAT_YDZJ            IND_STAT_DAY_COMPANY_MOBILE     P_201111
STAT_YDZJ            IND_STAT_DAY_COMPANY_AREA       P_201111

--查询无效全局index和普通index
SQL>  SELECT OWNER, a.index_name
  2     FROM Dba_Indexes  a
  3    WHERE OWNER NOT IN ('SYS', 'SYSTEM', 'PUBLIC')
  4     AND ROWNUM<2;

OWNER                          INDEX_NAME
------------------------------ ------------------------------
STAT_YDZJ                      PK_ND_STAT_DAY_COMPANY

2、解决问题
批量生产sql语句，重建这些unusable index

SELECT 'ALTER INDEX  ' || INDEX_OWNER || '.' || INDEX_NAME ||
       ' REBUILD PARTITION ' || PARTITION_NAME || ' NOLOGGING online;'
  FROM DBA_IND_PARTITIONS
 WHERE INDEX_OWNER NOT IN ('SYS', 'SYSTEM', 'PUBLIC')
   AND STATUS = 'UNUSABLE'
UNION ALL
SELECT 'alter index  ' ||OWNER || '.' || A.INDEX_NAME || ' REBUILD online nologging;'
  FROM DBA_INDEXES A
 WHERE OWNER NOT IN ('SYS', 'SYSTEM', 'PUBLIC')
 AND  STATUS = 'UNUSABLE';

执行完上面sql生成语句后，让开发测试程序，反馈工作正常

3、问题分析
我昨天对STAT_DAY_COMPANY表添加了分区(SPLIT拆分MAXVALUE)，本以为该表的所有index都是local index不知道为何有了一个全局index(公司规定所有分区表都只能建立local index)，所以没有做相关查询，导致这次出现了index无效。但是为什么还有三个local index也变成了unusable，这个估计是大批量append插入数据导致。而开发那边正好是批量append插入数据到STAT_DAY_COMPANY表中，导致出现了ORA-1502错误
建议：处理分区表时，要对index查询清楚，不要按照规定或者惯性思维办事。
