Colored Heat Maps in SQL*Plus

May 10th, 2013
The above is so cool. The graphic shows the latency heatmap of "log file sync". I was running a swingbench load and at the same time throttling I/O such that latencies started off good then got worse and then back to normal. All I did was type sqlplus / as sysdba @OraLatencyMap_event 3 "log file sync" This was created by Luca Canali , see http://externaltable.blogspot.com/2013/05/latency-heat-map-in-sqlplus-with.htm Now if we combine this monitoring, with the I/O throttling documeted by Frits Hoogland here https://fritshoogland.wordpress.com/2012/12/15/throttling-io-with-linux/ , we can really have some fun and even draw latency words: The above words in latency heat maps are from  http://dtrace.org/blogs/brendan/2009/03/17/heat-map-analytics/ where there is information on heat maps. In the graphic at ...

Database Virtualization: Data as a Service in Healthcare

April 24th, 2013
The healthcare sector has a clear opportunity to modernize care delivery by adopting new data interchange standards and EHR systems. But getting there will first require upgrading aging infrastructure, managing data explosion, and ensuring compliance with new regulations. This translates to more projects and greater costs for IT resources that are already stretched thin. There is a clear need for transformative technologies that will enable healthcare IT teams to tackle the unavoidable wave of big projects faster and with greater efficiency. Organizations like Presbyterian Healthcare Services, Health Dialog, Independence Blue Cross, European Bioformatics Institute and many others are leveraging Data Virtualization for databases ...

Installing OEM for second instance

April 21st, 2013
Had a machine running the default database from the Oracle 11.2.0.3 installer. This instance was called o1123. I then created a second database by hand (with crdb.sh for swingbench and slob tests) instead of dbca (maybe that was a mistake) and then I wanted to acccess OEM. The second instance was called SOE60G ( a 60GB swingbench dataset database) First tried to start up dbconsole: $ emctl start dbconsole OC4J Configuration issue. /home/oracle/oracle1123/product/oc4j/j2ee/OC4J_DBConsole_perf234-target1.delphix.com_SOE60G not found. OK, missing file. EM wasn't configured for this database, make sense. Let's configure it $ emca -config dbcontrol db -repos create ... SEVERE: Dbcontrol Repository already exists.  Fix the error(s) and run EM ...

Data Virtualization for Databases Use Cases, part 2

April 19th, 2013
previous segment at: part 1   Putting Virtual Databases To Use   Because the virtual database technology so drastically changes the way we think about cloning and provisioning new database environments, a myriad of use cases can also be envisioned that can take advantage of the saved storage and time. Additionally, these use cases fit perfectly into the model for accelerated development and management of a database environment. Development Environments This is the area where the biggest impact of data virtualization can be felt. Because the development environment is the first and most critical stage of application release, the benefits are widely felt and cascade into ...

Data Virtualization for Databases Use Cases, part 1

April 18th, 2013
followup at: part 2 It’s time that businesses took a good, hard look at the way they manage their cloned database environments. For years the words “we need a fresh copy of production in QA” were the universal sign of a horrible day. The amount of storage, server resources, and time required for provisioning a new database environment were often times unacceptable or at the least inconvenient. Thanks to Virtual Machines, the server resources have become far easier to provision. Within minutes a completely available virtual server could be ready to go, and often disk resources could be provisioned along with the ...
