    DB Tools Running Slow with Oracle

    Often people will write or call to express that some database tool like DBArtisan or Rapid SQL seems generally sluggish or that some screens may appear to lock up, taking as long to refresh as the refresh cycle, when accessing Oracle 10g, 11g, or 12c databases. They are often especially frustrated since this problem did not occur with Oracle versions prior to 10g. So what is DBArtisan doing that’s wrong (i.e. is...

    Why Explain Plans May No Longer Matter

    For far too long, database administrators and developers have focused on explain plans for tuning SQL statements that perform poorly. But with Oracle 11g and 12c , explain plans can quite possibly become a thing of the past. Furthermore, 12c can perform the entire tuning process automatically – with minimal time spent during the initial SQL development and maybe 1/10 th the effort spent addressing any problematic...

    We Don’t Need No Stinking Modeling Tool

    You’ll have to forgive me for spoofing the famous movie line “We don’t need no stinking badges” (Treasure of the Sierra Madre, 1948 and Blazing Saddles, 1974), it just seemed quite apropos. I was discussing data modeling needs recently with a potential customer – and like many shops I visit, they saw no need for data modeling. That their DBAs, data administrators and application architects...

    Oracle Parallel Query Abuse

    Oracle’s Parallel Query Option (PQO) is a fantastic tool. But much like any good tool, it can very easily be used in the wrong situation or simply abused. In those cases, PQO can actually make database performance much worse. Let’s examine some common misuses or misperceptions regarding optimal and efficient PQO usage. PQO make sense universally on any SMP or multi-processer database server. Not...

    Oracle Dynamic Scripting

    Ever wanted to perform some operation against all the objects in a schema? For example a one-time management task to turn off parallel for all tables and indexes. Another example might be an on-going task to disable and later enable triggers and referential integrity to speed up a recurring data load job. These types of tasks are not uncommon, however many people don’t know how to leverage dynamic SQL scripting...

    How Data Modeling Can Save Money

    It’s not uncommon to discover databases that have simply evolved over time rather than having been built according to some overall design or “master plan” . And there seem to be no shortage of answers as to why this occurs. Sometimes DBA’s are just far too busy with a myriad of other tasks. Sometimes developers are under the gun for deliverables so quickly that there’s just not time. Or my...

    Data Modeling Remains Relevant

    There are those who think that data modeling has become very passé’ these days. The belief is that because data modeling theory is over thirty years old and that since some data modeling tools have been around 10-20 years that somehow data modeling is now no longer relevant. Nothing could be further from the truth. In fact data modeling may now be more necessary than ever before. While there are other...

    Data Proximity for Data Warehousing Performance

    Data Warehousing DBA’s usually work with huge tables, often possessing hundreds of millions or even billions of rows. And occasionally, these DBA’s might need to perform maintenance that requires either recreating the entire huge table or some of its partitions. For example, the DBA might need to drop an unnecessary column or simply desire to de-fragment that table or some of its partitions (i.e. reduce the...

    Why Database Backup Compression Is Better Than Deduplication

    I often run into situations where DBAs are having discussions with their Storage Administrator around not compressing database backups so that they can get better deduplication from storage devices like EMC Data Domain. The Storage Administrator has been telling them not to compress their backups. I will tell you why this can be a bad idea. What is deduplication? Appliances like EMC Data Domain sit between the server...

    The Value of Data Modeling

    How do you convince your management that data models are worth the time and effort they require? You may be dealing with challenges around the value your company places on their data compared to how that data is actually managed. It can be difficult to assign a dollar amount and calculate a return on investment, but this is often what the business stakeholders need to see in order to justify and validate the use of data...

While we as individuals may scoff at new year’s resolutions, IT shops across the world make plans for the new year, building...

    Isolation Levels 101: Concurrency Issues

    The other day I had a client complaining about slowness, queries erroring out, blocking and processes stopping; you know the usual complaints. So, like any other DBA I pulled out my handy dandy toolbox of queries to determine exactly what was going on with the server. Upon reviewing their current running sessions, I noticed that the Isolation Level for a simple UPDATE transaction was “Serializable” and all...
