Don’t be afraid of having a look at the wikipedia-site, the math is not complicated at all ( you don’t need more than adding natural numbers smaller than hundred ), nevertheless the theorem is nice from a (more...)
In this post, we’re going to perform a push button refresh of an Oracle Database, Application Express (APEX) installation, and Tomcat webserver.
“But Oracle Alchemist,” you’re probably thinking, “we know about that. You’ve told us about how Delphix can provision and refresh data.” And yes, you’d be right. But I wasn’t done yet.
We’re going to perform a refresh of an Oracle Database, APEX installation, and Tomcat running in Amazon Web Services, replicated from (more...)
Yeah, it’s indeed true and official. So if you still haven’t started reading and learning Multitenant architecture introduced in 18.104.22.168 and enhanced in 22.214.171.124, it’s high time that you start doing it. Not because that it’s new but because the old architecture you are familiar with, it’s officially on the verge of extinction.
So it’s the first blog post of 2015 and what better can be than this that you can start 2015 with buying any e-book or video from https://www.packtpub.com/" in just $5 till 6th January 2015! I believe this is a great chance to grab your favorite book(s) or video(s) at a really really good price! And if you are undecided about which book to start from, how about from my 12c Backup (more...)
Only two things are really certain: network latency over long distances, and the fact that humanity will soon rapidly degenerate into undead brain-eaters.
When that day comes, when the dead are crowding at your door and the windows are busted out and ripped up rotted arms are clawing at the inside of your home, I know what you’ll be thinking: is my database protected?
Don’t worry, my friends. The Oracle Alchemist has you covered. We (more...)
Last week I attended Oracle OpenWorld 2014, and it was an outstanding event filled with great people, awesome sessions, and a few outstanding notable experiences.
Personally I thought the messaging behind the conference itself wasn’t as amazing and upbeat as OpenWorld 2013, but that’s almost to be expected. Last year there was a ton of buzz around the introduction of Oracle 12c, Big Data was a buzzword that people were totally excited (more...)
The only workaround was to deinstall wireshark including wincap and installing it again. But after the nex reboot, it freezed again.
After searching around i found the following fix, with cured this problem:
inside the registry you have to change the DWORD start in
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesnpffrom 0 or 1 to 2. After that wireshark will start properly even after reboots....
Today’s the first day of school in my city, and the plethora of “OMG 1st day of school!” posts of Facebook and my own kids heading back in to slog through another year of fundamentals got me thinking about education. My own kids (12/daughter and 10/son) came home and went swimming since it was about 104 degrees today…the hottest day of the summer, as it were.
Anyways, after that activity my son decided to (more...)
If you have done any play with the latest release of Oracle database 12c, you must have come across the concept of Common and Local users. I won’t rewrite what’s already there in the docs but for setting the context of the post, a Common user must be created with a prefix added to the username-C##. Miss that and you won’t be able to create one while being connected to the Container database. On (more...)
Seems like it’s going to be a week of new releases only. Last night only, I downloaded and installed Oracle database 12c patchset(12102) and today, Oracle Linux’s latest release OL7 is released. The download is available from E-Delivery portal and mine is going on. I don’t think it would take long before 12c would be certified for Oracle Linux 7 but I would do the installation of both, database and Linux, as soon as my (more...)
