Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

enq: CF - contention AWR Report

Jul 3, 2015 8:12AM edited Jul 15, 2015 10:06AM in Database Tuning (MOSC) 1 commentAnswered

Dear All,

I want to ask something about the control file contention that show up in AWR Report.

Following are my scenarios / detail about the situations:

I have a table that have LOB column with nologging and nocache attribute
I have another program (queue ) that connect to database using JDBC
When the program running, it will goes to the queue and then write/insert into the database

The problem are:

The queue is generated so fast (200-250 queues / second) and keep increasing
I see the database, yes the data is inserted but only (20-30 rows/ second) . note: 1 queue is equal to 1 row

0

Howdy, Stranger!
