Trying to get hold of my own course pdf for performance and tuning 11g, would oracle have list of classes i have taken?

Tyring to find my own course pdf for oracle performance and tuning 11g that I took thru Oracle.
I am studying for 1z0-064 currently using 10g perf tuning book.
Would Oracle have list of Oracle classes that i have taken.
If they do, is there any way to get hold of the pdf from the class that I took?
I realize that this is a stretch.

Roger,
This is a question that you'd need to contact Oracle University Support about - Oracle University Contact Information. They should be able to help you.

DNS best practices for hub and spoke AD Architecture?

I have an Active Directory Forest with a forest root such as joe.co and the root domain of the same name, and root DNS servers (Domain Controllers) dns1.joe.co and dns2.joe.co
I have child domains with names in the form region1.joe.com, region2.joe.co and so on, with dns servers dns1.region1.joe.co and so on.
Each region has distribute offices that may have a DC in them, servers named in the form dns1branch1.region1.joe.co
Over all my DNS tests out okay, but I want to get the general guidelines for setting up new DCs correct.
Configuration:
Root DC/DNS server dns1.joe.co adapter settings points DNS to itself, then two other root domain DNS/DCs dns2.joe.co and dns3.joe.co.
The other root domain DNS/DCs adapter settings point to root server dns1.joe.co and then to itself dns2.joe.co, and then 127.0.0.1
The regional domains have a root dns server dns1.region1.joe.co with adapter that that points to root server dns1.joe.co then to itself.
The additional region domain DNS/DCs adapter settings point to dns1.region1.joe.co then to itself then to dn1.joe.co
What would you do to correct this topology (and settings) or improve it?
Thanks in advance
just david

Hi,
According to your description, my understanding is that you need suggestion about your DNS topology.
In theory, there is no obvious problem. Except for the namespace and server plaining for DNS, zone is also needed to consideration. If you place DNS server on each domain and subdomain, confirm that if the traffic browsed by DNS will affect the network performance.
Besides, fault tolerance and security are also necessary.
We usually recommend that:
DC with DNS should point to another DNS server as primary and itself as secondary or tertiary. It should not point to self as primary due to various DNS islanding and performance issues that can occur. And when referencing a DNS server on itself, a DNS client
should always use a loopback address and not a real IP address. detailed information you may reference:
What is Microsoft's best practice for where and how many DNS servers exist? What about for configuring DNS client settings on DC’s and members?

Best practice for Plan and actual data

Hello, what is the best practice for Plan and actual data? should they both be in the same app or different?
Thanks.

Hi Zack,
It will be easier for you to maintain the data in a single application. Every application needs to have the category dimension, mandatorily. So, you can use this dimension to maintain the actual and plan data.
Hope this helps.

How similar is the performance and tuning 1z1-064 (12c) to the 1z0-054 (11g)?

I had taken the Oracle 11g performance and Tuning class from Oracle.
I am just wondering how close the 1z1-064 will be to the 1z0-054.
I am also studying for the 1z1-064 exam.
Are there any books out yet, or just the otn material.
Thanks Roger

Hopefully John Watson will pipe in on this. I know he has taken both exams. He recently noted on the OraFAQ forum that he had taken both the 1Z0-063 and 1Z0-064 beta exams. His comments about them there were:
"I would say that looking at the exams as a whole, there is a huge improvement over the 10g and 11g equivalents. The new exams cover a lot more material in a lot greater detail, and are a lot harder. These 12c exams are a Good Thing for the profession. They should filter out a lot of exam-cram only DBAs"
It's not clear to me how much of that comment was directed at 063 and how much at 064. The topic list for 063 is much larger than that for 053. However, the topic list for 064 is actually a bit smaller than that of 054.

Best/Easiest Practice for Distribution of Webhelp files for Fat(ish) Client Application

So another in my long line of questions in trying to change the implementation of the help systems at my new employer.
So, the pressure is to convince the existing guard to toss out the old method and go with a new method... One of the issues has come up for CSH Webhelp (via RH10)...
Apparently, in the old method (where every help topic was it's own CHM - no, I'm not kidding). They kept it that way so that any time a help file was updated, they could just send out that one chm to update that one topic.
Now they are worried that if we switch to webhelp using topics in one single big project that we can't just send out a single updated file any more...
So I'm trying to get ammunition as to how updates to the help can be distributed without it being a big hassle...
We do have small updates that go out about every week, and they are afraid that going to the webhelp (1 project with lots of topics) method will require more time and effort for the techs because they will have to complete the update of a huge help system every time.
One solution we have suggested is that we only update help files on major releases and add any changes to help procedures in the Release Notes or in a separate PDF and also include a note that the help files "will be updated to reflect this change in the XX/2015 XYZ Release).
Does ANYONE have any other ideas of how distribution could be done efficiently so that we don't have to continue this "project per topic" fiasco?
HELP!!! PLEASE!!!!

Amebr - you hit the nail on the head... i want to apologize to everyone for all this mass hysteria...but this has been a freaking rollercoaster... one day they are happy with the plan, the next day they decided they want to complicate it more... So now my job is to find out how viable and how tricky and perhaps how dangerous it will be to send out JUST the files that have been changed. Especially for CSH!
Anyone have any experience with this or have any advice? Peter? I suspect you might know how this might work... are they any pitfalls to watch out for.. I just have this fear of sending out a few files from an entire project... Altho, it appears when I publish, ONLY the files that have been edited in some way show a new date.. that includes non-topic files - so i'm assuming sending all those will keep the TOC, Index, and Search features working properly... as well as incoming and outgoing links from an edited topic?
Another question would be how to handle new images in a project... as the image folder tends to be the largest, i don't want to have to send the entire image folder... Thoughts...???? Advice? Jeff? Peter? Amebr? Bueller? Bueller? Bueller....?
THANKS!Best/Easiest Practice for Distribution of Webhelp files for Fat(ish) Client Application
OH... and Jeff... my apologies for the misnomer of using the term "Fat-ish" client in reference to this... I totally misspoke and should have said Mobile App... but in my mind, any time you have to download something to use it, it's a fat client... sorry! :-/

Satish,
Could you elaborate; are you looking for how to distribute the tiers(forms, web, conc., etc.); are you asking about PCP (parallelt concurrent processing)..

Can anybody recommend useful performance and tuning books. I plan to take the 12c perf tune beta on March 21st

Can anybody recommend any useful performance and tuning books.
I should probably limit my search to 11g or higher.
I am starting to prep for the 12c perf and tuning beta I have scheduled on March 21st.
Thanks Roger

Hi,
I will review your review.
I do see this Oracle 12c book at Amazon written over a year ago.
Its not a certificaiton book.
I also did take the course at Oracle for 11g performance and tuning.
Amazon book:
Oracle Database 12c Performance Tuning Recipes: A Problem solving approach.
Thanks Roger

What's the best approach/program for finding and eliminating duplicate photos on my hard drive?

What's the best approach/program for finding and eliminating duplicate photos on my hard drive? I have a "somewhat" older version of iPhoto (5.0.4), and it doesn't seem to offer anything like that except during the importing phase of syncing my phone...

I wonder, is there room to transfer them to your phone, & then back to filter them?
