The main header table is RLM_SCHEDULE_HEADERS_ALL which contains the information like schedule_reference_number and other details. In one schedule there can be many item records for different dates which are stored in the child table RLM_SCHEDULE_LINES_ALL. Both the tables are linked with HEADER_ID. Each schedule in header table has one horizon start date and horizon end date. Customer used to send these schedules every day for each item because of there business needs.
The requirement is to create a query to calculate the Net Change between the two schedules (Between the new and old). All the item records from child table for new schedule will be printed but only those item records from old schedule will be printed where schedule date in child table is within the horizon start date and end date of new schedule.
There are following indexes on the table RLM_SCHEDULE_LINES_ALL

Oracle10g ORA-00600: 内部错误代码, 参数: [kkocxj : pjpCtx], [], [], [], [], [], []

oracle10g的数据库，在执行一个存储过程是报错： ORA-00600: 内部错误代码, 参数: [kkocxj : pjpCtx], [], [], [], [], [], []
执行的sql语句如下：
execute immediate
'create table '||sDataTable||' as
select recid,wfrolepartid,actdefid,createdate,acttimestateid,finishtime
from (select a.createtime createdate, a.finishtime,
b.rolepartid as wfrolepartid,
d.actdefid,d.actdefname,
d.recid,
b.acttimestateid
from umdata.toevent a,
(select recid,rolepartid, acttimestateid from (
select recid,rolepartid, acttimestateid ,row_number() over (partition by recid order by createdate desc) n
from dlmis.towfactinst where prisubtypeid = 1 and actdefid in (47,49) )
where n=1 ) b,--专业部门--取最后一次派遣的
( select actdefid,recid,actdefname from (
select actdefid,recid,actdefname ,row_number() over (partition by recid order by actid desc) n
from dlmis.torecactall )
where n=1 and actdefid not in (53) --派遣
) d --去除了回退案卷
where a.recid = d.recid and d.recid = b.recid and d.actdefid!=7 )
where (createdate '||sParams33||')
将上面的语句拷贝出来单独执行查询部分的语句，不带条件也会报同样的错误。并且另一个相同的库部署在oracle9i上，完全一样，就版本不一样，没有这样的问题。
查了网上的一些资料，有给建议执行 alter system Set OPTIMIZERPUSH_PRED_COST_BASED = false 或者“Oracle GCS更推荐通过应用补丁7014646的方法来解决问题”两种方案的，我尝试了第一种执行sql报错。
因数据库是正式数据，不敢轻举妄动，希望大牛给出正确的解决方案，小弟感激不尽！！！！！

ora-00600[kkocxj:pjpCtx]内部错误一例
根据错误代码和stack trace可以在metalink上匹配到如下Bug:
Bug:7014646
Abstract: ORA-600: INTERNAL ERROR CODE, ARGUMENTS: [KKOCXJ : PJPCTX], [], [], [], [], []
Affects:
Product (Component)     Oracle Server (Rdbms)
Range of versions believed to be affected     Versions < 11.2
Versions confirmed as being affected
* 10.2.0.4
* 11.1.0.6
Platforms affected     Generic (all / most platforms affected)
Fixed:
This issue is fixed in
* 10.2.0.4 Patch 7 on Windows Platforms
* 10.2.0.5 (Server Patch Set)
* 11.1.0.7 (Server Patch Set)
* 11.2 (Future Release)
Symptoms:
* Internal Error May Occur (ORA-600)
* ORA-600 [kkocxj : pjpCtx]
Related To:
* Optimizer
* OPTIMIZERPUSH_PRED_COST_BASED
Description
A complex query can fail during parse with
ORA-600 [kkocxj : pjpCtx]
Workaround
Set "_optimizer_push_pred_cost_based"=false
该bug可以通过实施one off Patch 7014646修复，也可以尝试通过修改隐式参数_optimizer_push_pred_cost_based禁用基于成本的谓词前置特性(WORKAROUND: disable cost based push predicate)来规避该[KKOCXJ:PJPCTX]内部错误发生，具体的修改方法:
SQL> conn / as sysdba
SQL> alter system set "_optimizer_push_pred_cost_based"=false;
SQL> exit
/* 设置该隐式参数无需重启实例 */
Oracle GCS更推荐通过应用补丁7014646的方法来解决问题，而修改以上隐式参数则不一定百分之百能解决问题。

Select new ... join ... group by ... results in N+1 database accesses

Has anyone seen this behaviour?
In EJB3.0, using select new like this:
select new PeopleCount( p, count(tr)) from TechReport tr right join tr.people p group by p.lastName, p.firstNameResults in N+1 database hits. (N = number of rows returned). All accessing People objects. EG:
Hibernate: select person2_.URL as col_0_0_, count(techreport0_.URL) as col_1_0_ from TechReports techreport0_ right outer join TECHREPORT_PEOPLE people1_ on techreport0_.URL=people1_.TECH_ID right outer join People person2_ on people1_.PEOPLE_ID=person2_.URL group by person2_.lastName , person2_.firstName
Hibernate: select person0_.URL as URL105_0_, person0_.firstName as firstName105_0_, person0_.lastName as lastName105_0_ from Peopleperson0_ where person0_.URL=?
Hibernate: select person0_.URL as URL105_0_, person0_.firstName as firstName105_0_, person0_.lastName as lastName105_0_ from Peopleperson0_ where person0_.URL=?
times N - (Eeek!!)
Changing the query to use a regular "select":
select p, count(tr) from Report tr right join tr.people p group by p.lastName, p.firstNameResults in just one database hit. The person object is populated without extra database hits.
To see database hits, I added this line to presistance.xml:
<property name="hibernate.show_sql" value="true" /> So there's an obvious work around, but I'd like to understand why this is going on? Is it really a bug in EJB3.0? Any help appreciated!

CBO - Wrong Cardinality Estimate

Hello,
Version 10.2.0.3
I am trying to understand the figures in the Explain Plan. I am not able to explain the cardinality of 70 on step 4.
The query takes very long to execute (about 400 secs). I would expect HASH JOIN SEMI instead of NESTED LOOPS SEMI.
I have tried to provide as much information as possible. I have just requested the 10053 trace, dont have it now.
There is a primary key on ORDERS.ORDER_ID (NUMBER) column. However, we are forced to use to_char(order_id) to accomodate for COT_EXTERNAL_ID being VARCHAR2 field.
1 select cdw.* from cdw_orders cdw where cdw.cot_external_id in
2 (
3 select to_char(order_id) from orders o where o.status_id in (12,16,22)
4* )

   3 - filter("CDW"."COT_EXTERNAL_ID"=TO_CHAR("ORDER_ID"))

This is where my doubt is. Is this got to do with 22 being a popular value ? Can someone explain this behaviour ?
As a solution I am thinking of creating an index on to_char(order_id) - function based, hoping that the step 3 CDW.COT_EXTERNAL_ID = TO_CHAR(ORDER_ID) changes
to access instead of filter. Let me know your thoughts on the index creation as well.
Thanks,

Hello Jonathan,
Apologies, I was wrong about optimizer_index_cost_adj value to be set to 100. I gather from DBA the value is set to currently set to 1.
I have pasted the 10053 trace file for value 22. I was not able to figure out the "jsel=min(1, 6.1094e-04)" bit.
