OTN Yathra 2014 : Noida

I woke up today feeling a little dodgy and for a moment I thought it would be a repeat of my morning in Jalandhar. Fortunately, once we got moving and I drank some really sweet tea, everything was OK.

Today’s event was based at the Sharda University in Noida. We were introduced to the crowd, presented with some flowers and lit a ceremonial lamp to mark the start of the event.

I attended Aman Sharma’s presentation on Oracle Certification and the ACE Program. The students are very job-focused, so they were interested in certification and also what opportunities were available in the community.

Oracle Developer Day Perth

Well…it was a great day with over 100 people attending.

I had the standard fail of trying to show people 200 things that I think are important, in a time allowing only for 50 things, but better to be overfed than starving :-)

Links to the slides are below.  Thanks everyone for coming – hope you had a great day.

There is the  Mandel approach to power points in presentations where one is suppose to spend 3 minutes per slide, thus a 60 minute presentation is 20 slides or less.

How about going the other way, showing 3 or more slides per minute?

OTN Yathra 2014 : Jalandhar

Day one did not start well. I woke up and couldn’t stop throwing up. I got to the Lovely Professional University, thinking it would stop, but it didn’t. The people at the University were really helpful and took me to the University doctor, who gave me an injection to stop the nausea. A few minutes later, things calmed down, just in time for my first session…

As soon as I hit the stage I felt fine and the session went well. Adrenalin is a wonderful thing! After the session I started to flag a little, but I was taken to get some food, which picked me up. India is a great place for a vegetarian. I was a little nervous about eating after the events of the morning, but the food was great and I felt much better after it.

OTN Yathra 2014 : The Journey Begins

It’s been a really tough lead up to this tour. I’ve already blogged about the panic over my visa and flights. Since that post my flights were cancelled, switched to some different flights, then switched back again. I only got the final confirmation on the Thursday night before leaving on the Sunday.

What with that and me stressing out about some stuff going on at work at the moment, I felt like cancelling so I could lock myself in my house for 2 weeks and not speak to anyone. I’m in definite need of a holiday!

Today started off with a last-minute shop for a new suitcase. I had forgotten mine was broken, so I rushed out and bought the first thing I saw. I got home, packed, then got a banging headache. I had a couple of hours before my taxi, so I went to bed to try and sleep it off.

Runtime Load Balancing Advisory in RAC 12c-addendum

A reader asked an interesting question yesterday with regards to the previous post on the subject: where did you get your service metrics from when you queried v$servicemetric-PDB or CDB$ROOT?

I queried the PDB, but this morning repeated the test to make sure the results are consistent, and they are. This is definitely something you’d hope for: you should not have different results in the same v$-view depending on the container you execute your query in for a given CON_ID.

During testing I noticed something interesting though. I queried gv$servicemetric but did not limit the result to the service I wanted to test with (FCFSRV). Here is the query against gv$servicemetric while the system was idle.

RMOUG Training Days 2014

I made my way again this year to one of the best, if not the best, user group conferences, the Rocky Mountain Oracle User Group Training Days, held in Denver Colorado on the 6th and 7th of February. Huge kudos to Kellyn Pot’Vin and the rest of the organizing team (see her review here) for […]

Runtime Load Balancing Advisory in RAC 12c

This is a follow-up on yesterday’s post about services in the new 12c database architecture. After having worked out everything I needed to know about TAF and RAC 12c in CDBs I wanted to check how FCF works with PDBs today. While investigating I found out that the Runtime Load Balancing Advisory does not seem to work as expected in some cases. But I’m getting ahead of myself. First of all, here is my test case:

  • Oracle Linux 6.4 x86-64
  • Grid Infrastructure 12.1.0.1.2, i.e. January 2014 PSU applied
  • RDBMS 12.1.0.1.2, likewise patched with the January PSU
  • A CDB with just 1 PDB for this purpose, named DEMOPDB
  • Service FCFSRV is used

Service setup

The service is specifically created to connect against the PDB:
