1、检查alert日志发现错误

Check the trace file. Wed Nov 30 22:00:15 2011 Errors in file /opt/oracle/admin/ora9i/bdump/ora9i_j001_21372.trc: ORA-20000: index "VAS"."XN_CALLLOG_ANALYSIS_PK" or partition of such index is in unusable state
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
