In Response To: Cannot add index (Marcus Haarmann)

Hi,

Working from the error codes given and the example described where you just
brought up your personnel instance. I would ask this question:
Did you turn off scheduler ? the SCHAPI ?

If auto update stats is running against the given table you will not be
able to get an exclusive lock.

Try running the following in sysadmin a few minutes prior to running the
index create:

DATABASE sysadmin;

EXECUTE FUNCTION task("scheduler stop");

CLOSE DATABASE;

George.

Sent by: ids-bounces@iiug.org

Hi all,

we have a strange situation when creating a functional index.

Following table is base for this index:
CREATE TABLE crm_travels (

customer_id INTEGER NOT NULL,

item_id INTEGER NOT NULL,

supplier_id VARCHAR(32),

booking_id VARCHAR(20),

no_of_persons INTEGER,

date_of_booking DATE,

booking_user INTEGER,

start_travel DATE,

end_travel DATE,

status VARCHAR(2),

total_price MONEY,

booking_orgunit NVARCHAR(64),

order_id INTEGER,

order_no INTEGER,

mediator_id VARCHAR(32),

mediator_affiliate VARCHAR(10),

destination_code NVARCHAR(20),

traveltype_key VARCHAR(2),

transport_key VARCHAR(2),

persons_key VARCHAR(2),

destination_key VARCHAR(2),

duration_key VARCHAR(2),

PRIMARY KEY(booking_orgunit,customer_id,item_id) constraint
pk_crm_travels
)
ALTER TABLE crm_travels

ADD CONSTRAINT ( FOREIGN KEY(customer_id)
REFERENCES customer(customer_id) CONSTRAINT fk_crm_travels_customer )

Function to index is:
CREATE FUNCTION get_cust_first_travel_booking_date(p_customerId integer)

RETURNS Date with (not variant);

DEFINE first_booking Date;

select min(date_of_booking) into first_booking from crm_travels
where customer_id = p_customerId;

IF first_booking is null THEN

LET first_booking = MDY(12, 31, 1799);

END IF;

RETURN first_booking;

We want to add a functional index:
CREATE INDEX cftBookingDateIndex ON crm_travels (
get_cust_first_travel_booking_date(customer_id))

Error message is:
212: Cannot add index
106: ISAM error: non-exclusive access

I have tried this on my personal instance, freshly started, no sessions
active, executed in dbaccess.
IDS Version 11.50.UC5DE (Developer Edition, but also does not work in
Production 11.10FC3, same error)
Linux systems, Ubuntu on mine, Production with Debian 64bit

Any idea what we do wrong ?

Marcus Haarmann
