Re: RE: Could not do a physical-order read to fetc

In Response To: RE: Could not do a physical-order read to fetch ne (Alexandre Marini)

Hello Alexandre
Thanks for your prompt response.

Have you searched for any exclusive locks running on that mentioned table, before starting your java program?
-- I didnt find any locks running.

Pretty sure this is a highly accessed table on your OLTP,
-- Yes, exactly. 117 columns with 20 foreign keys.

1) is this a regular insert into your program, that will be running several times during the day?
--Yes atleast for every one second.

2) is this a specific long insert operation (eg bulk insert) ?
--Not exactly a bulk insert, it access for every single transaction and also some times user will insert some multiple 20 transactions at once.

Please find the online log of todays.
