Regarding the thread running more than 24 hours

Question

The below is the query executed from oracle side and is running more than 24 hours and not yet over. And multiple threads are running.
SELECT COUNT(*)
FROM snurk_cmms_csht009_rfs,
snurk_cmms_csht008_rfs,
snurk_cmms_csht001_rfs
WHERE snurk_cmms_csht001_rfs.cd_plant = snurk_cmms_csht008_rfs.cd_plant (+)
AND snurk_cmms_csht001_rfs.no_rfs = snurk_cmms_csht008_rfs.no_rfs (+)
AND snurk_cmms_csht008_rfs.cd_plant = snurk_cmms_csht009_rfs.cd_plant (+)
AND snurk_cmms_csht008_rfs.no_rfs = snurk_cmms_csht009_rfs.no_rfs (+)
AND snurk_cmms_csht008_rfs.ct_misc_item = snurk_cmms_csht009_rfs.ct_misc_item (+)
AND (snurk_cmms_csht009_rfs.ct_misc_item_page = 1
OR snurk_cmms_csht009_rfs.ct_misc_item_page IS NULL);
snurk_cmms_csht009_rfs,snurk_cmms_csht008_rfs,snurk_cmms_csht001_rfs are synonyms for views that are pointing to DB2 tables with the help of dblink.
The dba saying that the where clause in the above select is not sent to the db2 side so creating a cartesian product and asking us to add something in the where clause.

Please suggest on what to be added in the where clause.

Answer 1

We cannot create a view in db2 side because of security reasons. I tried to run the query as below.
SELECT count(a),count(b),count(c) FROM
(Select cd_plant,no_rfs,ct_misc_item, ct_misc_item_page from snurk_cmms_csht009_rfs) a,
(Select cd_plant,no_rfs,ct_misc_item from snurk_cmms_csht008_rfs) b,
(Select cd_plant,no_rfs from snurk_cmms_csht001_rfs ) c
Where c.cd_plant = b.cd_plant (+)
AND c.no_rfs = b.no_rfs (+)
AND b.cd_plant = a.cd_plant (+)
AND b.no_rfs = a.no_rfs (+)
AND b.ct_misc_item = a.ct_misc_item (+)
AND (a.ct_misc_item_page = 1
OR a.ct_misc_item_page IS NULL)
I am getting the error as below:
ERROR at line 4:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from FAST_SNURK_CMMS
How to troubleshoot this.
