Community and Regional Oracle User Groups

Back in 2002, as a Junior DBA, I was informed by the senior DBAs I worked with that I MUST become part of my regional user group, (RMOUG).  This was considered a requirement for any educated Database Administrator or Developer of the time and as those who I respected instructed, I became a member and […]

Consolidation Planning

More and more companies are consolidating environments.  Server sprawl has a high cost to any business and finding ways to consolidate to more powerful servers or to the cloud is a productive undertaking for any company. The Consolidation planner in Enterprise Manager has been around for quite some time, but many still don’t utilize this […]

The Queen of Social Media Mean

Unlike other forms of communication, social media can be a real gray area for rules on what dictates freedom of speech and how you have to endure with those that may not be pleasant to interact with.  I’m often told what etiquette some feel it necessary and that I should just disengage from some people […]

Zero Data Loss Recovery Appliance with EM12c, (ZDLRA)

I had a chance to take a closer look at the Zero Data Loss Recovery Appliance, (ZDLRA) via Cloud Control today and really liked the dashboard that’s included in the plugin for the product.  This post isn’t going to cover the installation of the plugin or configuration-  I was just intrigued by the dashboard and […]

A First Technical Look At Hybrid Cloning in EM12c Release 5

The sales, support and technical teams were brought into the Denver Tech Center office to do some advanced training in Hybrid Cloud.  There were many take-aways from the days we spent in the office, (which is saying a lot-  most of you likely know how much I hate working anywhere but from home… :)) and […]

12.1.0.5 Hybrid Cloud Cloning

Last week’s release of 12.1.0.5 was a pleasant surprise for everyone out in the Oracle world.  This release hit the bulls-eye for another cloud target of Oracle’s, announcing the introduction of Enterprise Manager 12c’s offering a single pane of glass management of the hybrid cloud.  The EM12c team has been been trained and testing out the […]

SQL ID Specific Performance Information

When you need to have information about one SQL_ID and don’t need everything and the kitchen sink, there are a few different ways to collect this via Oracle.  I’m surprised how rarely this is covered in performance tuning/optimization, (whatever the current “acceptable” term is for fixing a database when there are performance issues arise… J)  […]

Raspberry Pi 2 Shopping List

I recently upgraded from the first edition Raspberry Pi to the new and improved Raspberry Pi 2 in a bundle Cana kit.  The Raspberry Pi 2 has a 900MHZ quad-core Arm Cortex A7, (ARMv7 processor instruction set) with 1Gb of memory, GPU is a 250MHZ Broadcom VideoCore IV, 1080p 30 h.264/MPEG-4 AVC high profile decoder […]

 

Re-Adding a Database to the AWR Warehouse Without Losing Historical Snapshots

There may be a reason that one needs to re-add a database to the AWR Warehouse.  This is a new opportunity for me to learn and offer assistance, but I’m working off the grid to figure out a solution.  Luckily, it’s just a matter of creating a new process from pre-existing code and processes. The […]

ASH Data and How Sizing an AWR Warehouse Can be Mitigated

When sizing the AWR Warehouse, one of my requirements is to have certain reports for a sampling of databases that will source the AWR Warehouse. This report provides me the right information to create the correct sizing requirements vs. any assumptions done with other choices. The report is the General AWR Information report and can be […]

Kickstarting After a Failed Addition to the AWR Warehouse

A common issue I’ve noted are dump files generated from the AWR Warehouse, but upon failure to transfer, the dumpfiles simply exist, never upload and the data is stuck in a “limbo” state between the source database, (target) and the AWR Warehouse.  This can be a very difficult issue to troubleshoot, as no errors are […]

Here’s a quick guide to my schedule of sessions at IOUG Collaborate 2015 for this year.  I’m looking forward to seeing everyone next week, (I’ll be arriving on Saturday, so I really should say in a couple days) and have no doubt we’re up for another phenomenal conference at Las Vegas, this year at the […]

SQLd360 with the AWR Warehouse

Mauro decided to give me another challenge-  run SQLd360 against the AWR Warehouse and let him know how it does straight “out of the box”.  It’s a simpler installation process than SQLTXPLAIN, you simply unzip and run, (no installation of any packages…) I chose a SQL_ID from one of the source databases loaded and ran […]

SQLTXPLAIN and the AWR Warehouse- Part II

I finally have a moment to look into my “hacked” SQLT XPRECT/XTRACT runs and see if the changes I made were enough to run properly with the AWR Warehouse. The answer is yes and no… and maybe “it depends”… The Results The data from the AWR Warehouse to pull the corresponding data for the appropriate […]

SQLTXPLAIN and the AWR Warehouse, Part I

Yeah, so I did it-  I installed SQLTXPLAIN, (SQLT) on the AWR Warehouse!  From previous experience with this fantastic tool, I was pretty sure I’d have some great new adventures with the AWR Warehouse data and I wanted to try and test out the AWR pieces of this tool with the Warehouse. This is a work […]

One Year With Oracle

Just over a year ago, it became public that I was leaving Enkitec for Oracle.  Most folks had similar questions surrounding my decision, including my logic in giving up my ACE Director, an assumption that I would just disappear into the Oracle “machine”, considering the sheer size of the company and with my prominent company work […]
