In fact for a very junior position I don't think they are too bad a series of questions. They test the basic oracle and unix skills.

However, I prefer to enter into a discussion with a candidate by starting a very simple as question "what is the difference between logical and physical forward. Once it is answered you may ask why do you use logic, when using DG, which is DG broker, how do you build a standby, all according to the depths you want to enter. How the candidate's responses take you different paths.

Another favorite of mine is "what does 11 GR 1 material (or R2 now) you are interested in must" even if they have not used 11G I expect to have some opinion on what is and to come.

As I say, simple questions that you can take as deep you want to go based on the strength of the candidate.

Agree. It's pool question seems more appropriate to JuniorDBA. I guess that WhyNotOracle drawings for their management or simple filtering.

  • The system has encountered an error during the interview of the application. If the error persists, contact the system administrator

    Hi all

    We cloned an Oracle EBS R12.2.2 instance and it worked very well for us. To increase the RAM of the newly created virtual computer, we did the virtual machine down. Once the RAM has increased, we started all the services (without error), including level of DB and Application layer. But when we try to access the application of EBS get the following error:

    Hi all

    Thank you for your support. I solved the problem. Find the info below.

    ===================================================================================================

    Question: Like I said existing VM is cloned VM. Then after we had changed the host name. I checked the database alert log file:

    Before the reboot: name of the node was the previous still node name VM that it functioned very well. (for ex: xyz.domain)

    After the reboot: name of the node is replaced by the new host name. (for ex: abc.domain)

    Once the name of the node is changed he started creating problem in starting the application services.

    One last thing, I want to mention here after hostname change, approval of new contextfile has 700, but it should be 755.

    Solution: I followed these steps.

    (1) stop all services on the LAYERS of the DB and APP

    (2) change the new contextfile permission if not 755 and the .env at the level of the source DB

    (3) cd $ORACLE_HOME/appsutil/bin and run as: perl adgentns.pl appspass = apps contextfile = $CONTEXT_FILE - removeserver

    (4) change the name from old host to the new host name, so find in contextfile.

    (5) start listener, then the database

    (6) listener status, it must must give service to the db instance

    (7) perform autoconfig with new contextfile (DB Tier)

    (8) perform autoconfig (pane APP)

    (9) start all services

    ======================================================================================================

    It works for me, and now the application is running. I hope that it will also work for others.

    Thank you

  • A few questions during the consideration of the unique and professional license

    Hi all

    I am creating e-brochures for funiture products. But I have some questions when I choose a simple license or professional.
    Can anyone can help and answer to sub questions. Thank you

    1. for a single license, this means that I can download only 1 .folio for the application? Given that I intend to create a monthly e-brochure, if I downloaded a problem for Nov, can I upload another question for Dec? Will be that the application displays two issues?

    2 purchase guides, says Professional license includes free 5000 (annual) or 250 (monthly) .folio with the first year of service. This means that I can only have 5000 questions in the application for a year? or I can download only 5000 TIMES (which means that if I update/overwrite there is a question, I downloaded 2/5000 times)

    3. can I change the name of the app if I bought the single license?

    4. can I download the same application on the android market with a single license?

    5. is at - it offers Adobe upgrade plan? which means that I can use only permits first, if I think it's not enough, I can go from the plan to the Professional license.

    I am very confused with the purchase of guideline comparison. My goal is to create a number monthly e-brochures. Any suggestion to choose the appropriate license? Thank you

    1. with the single license edition DPS, you can create built-single edition app. If you plan to create several Folio app, then you should go with DPS Professional edition.

    2. it means you get complimentry 5000 downloads in DPS annual Pro and 250 per month in the case of DPS Pro monthly. You can have unlimeted number of folios, and you can update your folio number n times. It only means that you get 5000 or 25o parmois downloads in your POS with DPS Professional edition.

    3. Yes, you can change the name of the application.

    4 Currenlty with DPS single edition, you cannot create built-single edition app. DPS Professional edition is required to create an application for Android market.

    5 no.

    According to you need, I suggest you go with DPS Professional edition.

  • A Question during the upgrade...

    I thought to upgrade database to 8.1.7.4 to 11.2.0.2, the thing is if someone had very low system and the requirements of the OS, if they wanted to upgrade to another version, other than the path of update that is mentioned in metalink, who can run in their demand for now.

    For example,.
    the real upgrade path is.

    8.1.7.4 = > 10.2.0.4 = > 11.2.x

    What happens if we improve this way...

    8.1.7.4 = > 9.2.0.8 = > 11.2.0.2.0

    It will create problems... What are the problems that I will face?

    I do not know how to ask this question more perfectly, I hope that you guys understand my question... I'm sorry if this has been asked before... Please help me here... :-)

    Hello
    Yes you are right.

    Don't be confused with the different paths. In my understanding the upgrade guide shows the most simple/more short/possible path to upgrade. Note 730365.1 shows all possible combinations consisting of two versions upgrade.

    Thing about it: you started with 8.1.7.4, a few years later you upgrade to 9.2.0.2 (valid path in the 9.2 upgrade guide), then you the path to 9.2.0.8 a few months later. Yet once a few years later - now - "finally" upgraded you to 11.2.02. As 9.2.0.8-online 11.2.0.x is a valid path, you did exactly what you want.

    Hope that clarifies my ideas.

    Good luck

  • ROWID question during the passage of the element with f? rating URL p

    Hi all

    Recently, I encountered a problem trying to pass the ROWID as a parameter in f? rating p on hidden item URL. No matter if the item is hidden or is just a text field, in apex cut somehow the symbol '+' if it is contained in the rowid.
    Therefore, when I refer to this article, I get the error ORA-01410 ROWID invalid.

    the reference is as follows:

    Do not erase everything on your phone under the procedure of release.  If you have your phone set to backup Contacts on iCloud, they will be saved and then can be later reloaded on your phone after erasing it.  I just got two iPhone 5 and it worked well.  Also to do a full backup to your computer via iTunes and transfer everything what is not already saved if you are asked.  The only problem I encountered was that some applications does not and I had to manually reinstall the.

    You experience slow response on normal s tablet, the first gen one or the Xperia s tablet, a new.

    If you experience a slow response, it may be because you use too many apps at the time and slowing down of your tablet. How long it lasts?
