The Arizona Oracle User Group (AZORA) is meeting this Thursday, November 16th, 2017 from 12:30 to 3:30 pm Arizona time.

SQL Profile to fix slow inserts

I was on call Sunday and got paged about a job that normally runs for 10 to 15 minutes but had run for 5 hours already. I used the coe_xfr_sql_profile.sql script from SQLT to speed up an insert statement that was part of the job. We restarted the job and it completed in a few minutes.

I have written a number of posts about the use of coe_xfr_sql_profile.sql. Sunday’s issue was most like the post (more...)

Two Talks Accepted for RMOUG Training Days

I got two talks accepted for RMOUG Training Days in February. I mentioned these two titles in a earlier post:

  • Python for the Oracle DBA
  • Toastmasters for the Oracle DBA

These two talks are about topics that interest me so I am glad that RMOUG thinks that they are valuable to the conference attendees.

I plan to do the two talks for my DBA coworkers and shorter versions at Toastmasters so I should get some constructive (more...)

Submitted two talks to Collaborate 18

I submitted my two talks to Collaborate 18 through IOUG. These are the same two that I submitted to RMOUG Training Days. Hopefully one of the talks will get accepted at one of the two conferences but I don’t know. The nice thing is that they are both professional development talks and a user group meeting might be more open to that sort of talk than a vendor (i.e. Oracle OpenWorld) conference. But, there (more...)

Python sortedcontainers has me thinking

I was looking at the Python sortedcontainers package and it got me thinking. It is a long convoluted story and I am not sure that I can explain it clearly in a short blog post. I tried to explain all this to my wife in the last few minutes as we were driving up to a friend’s house last night and I’m sure it was confusing the way I explained it. But, I’m hoping that (more...)

Submitted two abstracts to RMOUG Training Days 2018

I finally broke down and submitted my two talks to the RMOUG Training Days 2018. I’m not sure how likely I am to get my talks accepted but I learned a lot just through constructing my two abstracts. I have two talks that I have processed in my mind for a while:

  • Python for the Oracle DBA
  • Toastmasters for the Oracle DBA

These are just two things I’ve worked with and that I think have (more...)

Duplicate blog to laptop VM

I started to write this blog post and then realized that in the process of making a copy of my blog on my laptop I whacked my connection to WordPress. But, it was easy to resolve it by disconnecting Jetpack from WordPress, clearing my browser cache, and then reconnecting. Whew! I worried that messing with this stuff would cause some problem but the blog still seems to work.

My idea was to bring up a (more...)

Quick Python script to backup remote directory using ftp

I looked around for some other ways to do this but decided to just code this up in Python. It connects to a remote Linux server using ftp and recursively copies all the files and directories back to a Windows machine.

Here is the source:

This is an example of the ease of use of Python for quick scripting. It uses a low-level ftp library called ftplib.

Added save and restore data function to PythonDBAGraphs

I pushed out a quick change to PythonDBAGraphs to automatically save the data for any graph that you make so that you can redraw the graph later. This is better than saving an image file because the redrawn graph lets you see details about the points on the graph when you hover the mouse over the points.

Now when you generate a graph you get a line like this:

Saving data in C:\temp\ASH active session  (more...)

Python for the Oracle DBA – Connects to everything

In my introduction to my Python for the Oracle DBA topic I said that Python can connect to everything that an Oracle DBA needs. I want to use this post to expand on that and talk about the Python modules and packages that I have used.

As you might expect, Python includes built-in modules and ones that you can add. Python comes with a large built-in library called the Python Standard Library. To use these modules (more...)
