Hi listers,

I have a table that is accessed by only one transaction.  It has 1500 rows each time that it processes

This transaction.  As soon as this transaction ends, it waits 10 seconds and starts again. 

It has another maximum 1500 rows loaded. . 

 

My question is this:  I believe a RowExclusive level lock is acquired 1500 times during each transaction.

Is this true?  Is there a way to disable RowExclusive locks and reduce overhead since only this transaction

Accesses this table.   I know there are ways to specify locking levels in other DBMSs. To page or table levels.

We are currently at version 7.4.5.

 

Thank you for your time,
