I have a couple of applications which do long queries in an OLTP database. They however have a significant impact on database server load.
Is it possible to run them with low priority? Is still intend to allow the user make adhoc queries, but response time is not critical.
Please advice solutions for oracle and/or sqlserver.
If you’re using 11g, then perhaps the Database Resource Manager will help you out. The resource manager allows you to change consumer groups based on I/O consumption, something that was unavailable in prior releases. If not, the best you can do is lower priority based on CPU use.
