BGOUG Autumn Conference - Extraordinary trip

it's 19-Nov-2015 and this day means that i should start packing and prepare myself for traveling to Bulgaria, at first everything was normal and i thought it will be like any other trip i did before.

since there is no direct flight to Bulgaria then i should landed in Frankfurt first then to Sofia as most of you know i don't like early flight despite i am waking all the night working or replying some emails but it's something i don't like to do :) anyway my flight was at 3:00 am from Jordan i did boarding thing and visa & security Check after 6 hours i landed in Germany,drink coffee in the airport and ran to my next flight Sofia.

When i landed in Sofia it was 1:30 pm exactly, so like any other airport i should pass by immigration officer & this is what happened :-

Me :- Hi, Good afternoon.
officer : Hi, your passport please.
Me ; Sure.
Officer "Scan the visa" and the System start rining.
Me: is there something wrong.
Officer: mmmm come with me please.
Me "in my mind" did i do anything bad before i came here.
Officer : Your visa valid from tomorrow.
Me: Kidding right ? So what ?
Officer : you have to wait till 12:00 am then you access to Sofia.
Me : it's almost 12 hours man.
Officer : it's Ok you can go upstairs and have some drink and food if you want.
Me : Sure, i am gonna have more than this.

So i wait in the airport and during this i sent an email to Milena to inform her that i will not be available till 12:00 am and told her what is happened to me.

I would like to thanks all of them actually Milena, Heli and Gurcan  these guys was checking on me :).

Wait my story not end here, When i went out of security check now i have to start search of my luggage which i found it in Lost & found Department for more information about this part contact me :)

anyway the conference was really good i had two presentation about middleware with live demo, i don't know why the live demo before the presentation working fine but during the presentation it stop working for stupid reasons but live demo is always challenge

everything was well organized  and conference was really amazing.

Safe Trip my friends :) and meet you soon Inchallah.

Oracle Open World 2015 review

As all of you know Oracle open world 2015 finished before 2 days ago, and simply it's was amazing, my trip started on OCT-21-2015 Wenseday and it's was totally morning flight which mean i supposed to be in airport at 4:00 am because of to avoid miss my flight i didn't sleep, the flight was from Jordan - Amman to Turkey - IST and then to SF, when i landed in IST i met my old friend Gurcan Orhan this man is awesome, he managed everything from our seats to waiting in the lounge but i have to say he spent 11 hours sleeping from IST- SF. meanwhile i was watching San Andres movie which i discovered later it was bad idea , in case you didn't watch it's movie talking about earthquake happened in San Francisco, actually i watched all the entertainment movie and i was thinking what i will go when i will be back home ? simply i watch San Andres again.

anyway we landed after 13 hours of flying and we met the great Tim Hall the great oracle guy i am sure this man is helping a lot of DBA with his amazing blog. so we took the shuttle "tim, Gurcan, Arup,cary , simon and me".

Don't forget this is was my first OOW15 as ACED :), so i attended ACED Breifing and meet my old friends there, during the two days i learnt alot of new things about Oracle that i can't mention it here because the NDA, and i want to thanks Oracle ACE program to organizing all this and make it true so let's skip this part.

OOW15 started on sunday with an amazing weather, attending session about RAC, Database just like arup said " there is database and everything else" and sure the middleware sessions.

I had so much fun & learning, the funny thing that i met Deiby and nassyam for the first time and these guys are simply funny and crazy :) i think we can be called the four musketeers "Me, Alex Zaballa, Deiby and Nassyam"

Let's not forget the amazing friend all over the world such as : Bobby, Danny Bryant, Kellyn, Heli,  Steve , Kevin ,Mahir, kamran, sai ram, Joel and a lot of amazing people and friends but i can't feel my fingers :) 

Also The ACE dinner on Sunday night was awesome,almost all the ACE's in one place and we had so much there, in OOW I lost twice with F1 Simulation but i want one of these machine anyway.

and i noticed that i am not good at all when i am eating spicy food i spent my time like the following  one hand drink water the other one wiping my tears. thanks for Sai , Nassyam and Hariharaputhran.

there is so much to say about OOW15 but this is as quick review for it and if you have any more question about it you can ask me :)

Error : Cannot export Display Linux

There are different tools to do X11 forwarding on Windows one of them Xming it's small software and very easy to use no need to do any special configuration only run the installation file.

But sometimes you are using this application and try to run the GUI on your desktop or laptop it's working like you excepted, one simple solution to solve it.

I am using as ssh client Putty, before put the server ip from putty left panel

  • Connection > SSH > X11
  • Check X11 forwarding: [x] Enable X11 forwarding
  • Add to the “X display location” field: localhost:0.0
