Query on oracle database 11.2.0.3 is slow

edited Jun 20, 2017 5:05AM in SQL Performance (MOSC) 3 commentsAnswered

HI,

I am having issue with my application database which I noticed slow in below scenario. (database server  has 8 Core and 48 GB Ram, pga_aggregate_target=9G , sga_target=18G )

1. Update command taking long time on custom table (400 records only) -- This is the scenario, Initially we created table with 3 column and after few days we added 2 more column to a table, now we were just putting dummy values in this 2 column using update command and it waited for 5-6 minutes after which we killed the session. There was no lock on any other object.

In this case, how should I troubleshoot on why it is taking time and what is making the update slow etc?

Howdy, Stranger!
