Descending index results in DB connection being terminated

Question

Hi all,
This is on Oracle 10g 10.1.0.3.0.
I have a table created using the following DDL:
Create table orders
purchase_order_id number,
ext_order_id number,
ext_ad_id number,
member_id number constraint campaigns_n1 not null,
status number(2) default 0 constraint campaigns_n2 not null,
name varchar2(50) constraint campaigns_n3 not null,
cost_type varchar2(10) default 'CPM' constraint campaigns_n4 not null,
unit_cost float constraint campaigns_n5 not null,
num_days number,
start_date timestamp,
end_date timestamp,
quantity number constraint campaigns_n6 not null,
key_val_targeting varchar2(2048),
ext_query_id number,
last_report_date date default sysdate,
last_update_time timestamp default systimestamp constraint campaigns_n7 not null
INITRANS 1
MAXTRANS 255
PCTUSED 60
PCTFREE 40
TABLESPACE TBS1
NOCACHE
With the following index:
create index orders_i1
on orders(status desc, last_report_date)
SORT
INITRANS 2
MAXTRANS 255
PCTFREE 10 TABLESPACE TBS1
When I execute the following query, my DB connection is immediately terminated (this is true of sqlplus, as well as a JDBC connection to the database), without any data being returned:
SELECT /*+ index (ORDERS ORDERS_I1) */ PURCHASE_ORDER_ID, EXT_QUERY_ID, STATUS, LAST_REPORT_DATE, MEMBER_ID, EXT_ORDER_ID FROM
ORDERS WHERE (STATUS = 3 OR
(LAST_REPORT_DATE <= sysdate - 3 AND (STATUS in (2, 4))))
AND ROWNUM < 5;
When the connection is terminated, I see the following message (in sqlplus):
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Any clues as to what might be causing this? Since I don't get any sort of reasonable error, I can't really make out what the problem is.
thanks!

Hi,
I too have a similar kind of a problem.
My view is:
CREATE OR REPLACE VIEW EXPENSE_HEADER AS
SELECT /*+ INDEX (expense_header_tab expense_header_ix3)*/
company_id company_id,
expense_id expense_id,
start_stamp start_stamp,
end_stamp end_stamp,
FROM expense_header_tab
WITH read only
index is:
DECLARE
     columns_ Database_SYS.ColumnTabType;
BEGIN
Database_SYS.Set_Table_Column(columns_,'COMPANY_ID');
Database_SYS.Set_Table_Column(columns_,'EXPENSE_ID DESC');
Database_SYS.Create_Index('EXPENSE_HEADER_TAB','EXPENSE_HEADER_IX3',columns_);
(Database_SYS is a package that we use in the framework for DDL related work)
When I try to run a query with more than one value connected using OR conditions in the WHERE clause SQLPlus gives a end-of-file communication error. This does not happen for a single value or any other clauses.
problamatic query:
select * from expense_header t where (EXPENSE_ID = '201405' or EXPENSE_ID = '201406')
Any ideas?
Thanks!
