ORA-12801: error signaled in parallel query server P005
昨天有个分区表，交换了30多个分区（将业务表30多个分区交换到历史表，然后删除业务表这30多个分区），然后今天早上收集统计信息的时候报错了，请教各位，这个需要重建索引吗？为什么收集统计信息的时候会报错？请各位指教，alterlog和trace信息如下：alertlog：

看看alert.log失效的时间戳呢。 不是吧，中午的时候，有报失效的信息，收集是在凌晨的，还有，local索引，为什么会exchange、drop索引之后，失效呢？

具体是如何 exchange 和drop 的给出命令和对象DDL
大概就是这个，写个一个procedure，我是手动改v_part_day变量一天一天交换，然后删除的
CREATE OR REPLACE procedure pro_parttable_auto
as
v_table_name varchar2(100);
v_part_day varchar2(100);
TYPE type_array_str IS TABLE OF VARCHAR2(32) INDEX BY VARCHAR(32);
v_array_table type_array_str;
begin
v_array_table('STATIC_AGG_HOUR') := 'PART_AGGHOUR_';
v_array_table('STATIC_AGG_PROVINCE_DAY') := 'PART_PROV_';
v_part_day := to_char(sysdate-90,'yyyymmdd');
v_table_name := v_array_table.FIRST;
execute immediate 'alter table STATIC_AGG_HOUR exchange partition PART_AGGHOUR_'||v_part_day||' with table EXCHANGE_HOUR_TEMP without validation';
execute immediate 'alter table HIST_AGG_HOUR_2013 exchange partition HIST_HOUR_'||v_part_day||' with table EXCHANGE_HOUR_TEMP without validation';
execute immediate 'alter table STATIC_AGG_PROVINCE_DAY exchange partition PART_PROV_'||v_part_day||' with table EXCHANGE_PRODAY_TEMP without validation';
execute immediate 'alter table HIST_PROVINCE_DAY_2013 exchange partition HIST_PRODAY_'||v_part_day||' with table EXCHANGE_PRODAY_TEMP without validation';
commit;
loop
exit when v_table_name is null;
begin
EXECUTE IMMEDIATE ('ALTER TABLE ' || v_table_name || ' DROP PARTITION ' || v_array_table(v_table_name) || v_part_day);
insert into a_droppart_log values(sysdate, v_array_table(v_table_name)||v_part_day);
commit;
end;
v_table_name := v_array_table.next(v_table_name);
end loop;
end;
/
alter table STATIC_AGG_PROVINCE_DAY exchange partition PART_PROV_'||v_part_day||' with table EXCHANGE_PRODAY_TEMP without validation
对于 exchange partition且希望维护索引的 语法如下：
ALTER TABLE sales EXCHANGE PARTITION SALES_Q4_2003 with
table SALES_TMP INCLUDING INDEXES WITH VALIDATION UPDATE GLOBAL INDEXES Maclean Liu(刘相兵 发表于 2014-3-4 12:20 static/image/common/back.gif
alter table STATIC_AGG_PROVINCE_DAY exchange partition PART_PROV_'||v_part_day||' with table EXCHANG ...
索引类型是local分区索引，exchange也需要update global indexes吗？
SQL> select index_name,table_name,locality from user_part_indexes;
INDEX_NAME TABLE_NAME LOCALI
------------------------------ ------------------------------ ------
IDX_PROVINCE_DAY STATIC_AGG_PROVINCE_DAY LOCAL
注意 6楼 红字的2部分：
http://docs.oracle.com/cd/E11882_01/server.112/e25523/part_admin002.htm
INCLUDING | EXCLUDING INDEXES Specify INCLUDING INDEXES if you want local index partitions or subpartitions to be exchanged with the corresponding table index (for a nonpartitioned table) or local indexes (for a hash-partitioned table). Specify EXCLUDING INDEXES if you want all index partitions or subpartitions corresponding to the partition and all the regular indexes and index partitions on the exchanged table to be marked UNUSABLE. If you omit this clause, then the default is EXCLUDING INDEXES.
