Concurrent read from a partition table.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I’m having a problem with concurrent processing. 
2 queries are accessing the same parent table  that have 24 partitions.
I see “shared lock is not granted “ for one of them on one of the children
while the other query is running.

Does the “ select from a parent table” make a  lock on  the children?

How I can change it? 
The one of the queries runs hourly ( 8 min) on the server , the other one 
can be run by a user , and a few users can run the same query. 

Thank you.
Helen
