Feed: Striving for Optimal Performance. The contents of the V$SQL_CS_HISTOGRAM view is used by the SQL engine to decide when a cursor is made bind aware, and therefore, when it should use adaptive cursor sharing. For each child cursor, the view shows three buckets. It is of general knowledge that the first one (BUCKET_ID equal 0) is associated with the executions that process up to and including 1,000 rows, the second one (BUCKET_ID equal 1) with the executions that processes between 1,001 and 1,000,000 rows, and the third one (BUCKET_ID equal 2) with the executions that processes more than 1,000,000 ...

I decided to write this article while answering this Stack Overflow question asked by Rafael Winterhalter. Since SKIP LOCKED is a lesser-known SQL feature, it’s a good opportunity to show you how to use it and why you should employ it, especially when implementing a job queue task.

In addition, when the DB instance is running in a Multi-AZ configuration, the data for each device on secondary host is collected as well secondary host metrics.   Both physical device and Multi-AZ secondary host metrics are available on RDS for Oracle, PostgreSQL and MySQL. With data reported on each physical device, you can see how many physical devices make up their volumes, if I/O is balanced across physical devices, and see if latency is consistent ... Read More

Feed: AWS Compute Blog. Author: Sandy Carter. We’ve been talking to many customers over the last 3–4 months who are concerned about the total cost of ownership (TCO) for running Microsoft Windows workloads in the cloud.For example, Infor is a global leader in enterprise resource planning (ERP) for manufacturing, healthcare, and retail. They’ve moved thousands of their existing Microsoft SQL Server workloads to Amazon EC2 instances. As a result, they are saving 75% on monthly backup costs.

Feed: Kamran Agayev's Oracle Blog. Last week we had a clusterware issue on one of the critical 3 node RAC environment. In the first node, network resource is restarted by ending up killing all sessions on that node abnormally. Oracle VIP that was running on that node failed over to the third node. The first node was up and running, but didn’t accept connections because it was trying to register the instance using LOCAL_LISTENER parameter where the oranode1-vip was specified that was not running on that node. We tried to relocate it back to the first node, but it failed ... Read More

Feed: Databasejournal.com - Feature Database Articles. Author: . For every timeless adage there is at least one mistaken thought that can become 'truth' simply by virtue of being repeated. Oracle is no exception to this phenomenon especially when single-column Primary Key indexes are involved. The conventional 'wisdom' discounts the use of histograms on such an index as unnecessary, and this presumes that the primary key has no 'holes' and has a continuous range of data. Very often reality flies in the face of that assumption; even with triggers and sequences, it is highly unlikely to find an unbroken, gap-free data ... Read More
