Question on portal of the OAS and the DB conections

Hello

I get a lot of problems with the portal I created, sometimes my DB goes down
with this error:
--------------------------------------------------------------------------------------------------------------
Fallo de la llamada para ejecutar el origen de datos. [No se ha podido establecer la conexión.
This line in english says something like: 
Fail calling to execute data. [ It was not possible to stablish the connection
--------------------------------------------------------------------------------------------------------------
 
 [Listener refused the connection with the following error: ORA-12519, TNS:no appropriate service handler found The Connection descriptor used by the client was: desarrollo06:1521:infra ]
so I have to but in decline in all services and then put them up once again, including the DB, so that everything works well again.

I want to know:
-How many omniportlets or conections to the database can handle the OAS Portal?
-Is the firm of omniportlet the conection when he loaded information?
-Can there be a problem if I use many omniportlets (I mean if they close their conection?)?
- And if so, how can I fix it?

Thanks in advance,

aTTe:

Hi Blume,

1. the number of handles of portal with your db connections is configured in the JDBC connection Pool settings.
2. don't think.
3. I think, Yes, some of them will be the expected behavior (for example, the number of connections limit is exceeded), and some of them are due to a few bugs (see answer 4.)
4. There are a few bugs related to this Portal 10.1.4 login problem.
for example, check this note on Metalink (Doc - ID: 394089.1) who says that:

"OMNIPortlet uses connection from the connection pool object. JDBC The database is restarted, the cached connection is not valid and the exception has not been taken. »

To resolve this problem, you may need to apply a patch (hotfix 5393955) on your gate high. You can get it from Metalink.

5 btw, stop db not may need to recover/restore connections; try simply restarting OC4J_Portal on AS Command Console.

hope that helps!
AMN

My question is, somehow harm the Xoom to 2 to use the doc just as a stand?

  • Exchange server and Surface RT, can I use Mail app to connect to the Exchange Server for email (the same question is for contacts or people and calendar)?

    Hello

    Our company uses an Exchange Server for email, contacts and calendar.

    Can I use Mail app to connect to the Exchange Server for email (the same question is for contacts or people and calendar)?

    Kind regards

    Matej

    You must install the SSL certificate before connect you to the Regional service, the easiest way is to go to "desktop" IE10 open, go to the exchange server web access page, click on the notification of "certificate error" red and view / install the store "certificate authorities roots of trust." Then, make sure that your surface RT complies with the minimum requirements of security then connect to the exchange via the mail application server.

    AFAIK, you can't share a catalog like this.

    The only recommended method is to store your images and catalogue on an external drive, you can alternatively plug in both computers.

    With today the external USB drives, the speed is still correct, and many users are satisfied with this solution.

  • Safari with question marks instead of the text

    Several Web sites in Safari 9.1 showing many points of question marks instead of the text. I just proposed by Apple and done nothing. I have Imac (late 2009) OS X El Capitan 10.11.4.

    Question marks instead of the text is an indication of a problem with fonts.

    Open the book fonts in your Applications folder.

    In the fonts start menu bar click book fonts > Preferences and then click: resolve duplicates by moving the files to the trash

    Quit and then restart Safari to test.

    If this does not help, back to the font book menu bar click file > restore to the Unicode Standard

    Quit and then restart Safari to test.

    Thank you

    Hello

    in your case it s not possible to change the size of graphics by yourself, memory as graphics memory in your machine is shared with main memory, so if you upgrade main memory and graphics memory should increase. But this question is governed by the chipset and the user has no influence on it.

    What is raid? A large number of people I know use raids.

    RAID 1 (mirroring) is not a backup solution. RAID 1 uses two or
    Several readers, each one duplicate of the other, to provide redundancy,
    no backup. It is used in situations (almost always inside)
    companies, not in homes) where any city cannot be tolerated.
    because the way it works is that if a disk fails the other takes
    more seamlessly.

    Although some people thing of RAID 1 as a backup technique, it is
    what it is, because it is subject to a simultaneous loss of the
    original and many of the main dangers facing the mirror
    your data - serious power, close to the lightning seeds, virus
    attacks, stolen computer, etc. Most companies that use RAID 1
    also have a solid plan of external backup in place.

  • How can I make a tab by default whenever I have connection to the portal of the webcenter spaces?

    Hello

    I have a single page in the portal of webcenter spaces, which is the default portal in the webcenter application. This single page has 6 or 7 like Home tab and the other tabs. Whenever I logged in the webcenter I can see the url redirects to my default portal but it doesnot get home tab made, instead, it shows the tab where I left just before disconnected tab.

    For example I have tabs A, B, C, D etc... I have logged in to the application portal and I did something in tab C and then I logged. After once again I re-login, I see this tab C shows, but I want to see that tab must be returned. Someone help me how to make a tab by default whenever I have connection to the webcenter portal.
