  Dear all,

  We can share with the Community (related to oracle) document which can be useful for someone... ? Is there a specific place, so that it... where, once that we download... our document is checked and published if it is deemed sufficiently credible... ?

  Question has now moved to the space of the feedback from the community.

  The community provides for the possibility for members to upload documents to the content-> spaces of Documents in the workspace of each product (if available).  However, the feature is currently disabled for most members due to problems with spam, so only a few members (most of Oracle employees) have the necessary permissions to do this.

  The admin studying how they can implement something that would allow members to upload documents, etc., which also has some mechanism to prevent spam.

  There is an idea already created for this: allow users to create community Documents

• APEX does not open after you have created the new Oracle listening port

  Hi guys,.
  
  I had to re register Oracle listener using "lsnrctl start". A new listening port has been created and I am able to connect user Apex by PL/SQL Developer. Port 8080 is open.
  But if I try to open the application APEX of URL (http://localhost: 8080/apex/f? p = :::) 4550:1:0 its not opening not.) It was working fine until yesterday.

  Link to your thread to listen would have helped: Oracle XE 11g with Apex No problem of Listener (ORA-12541: listener TNS:no)

  It seems that your listener uses the static instance via the listener.ora file registration and missing entries for the http service. Edit your listener.ora (F:\Apex_Installed\app\oracle\product\11.2.0\server\network\ADMIN\listener.ora) file and add the following entries in the listener.ora file DESCRIPTION_LIST. Then, restart the listenerer.

  (DESCRIPTION=
    (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=8080))(Presentation=HTTP)(Session=RAW)

• start the Oracle listener on openSuse

  How can I configure oracle listener to be launched at startup on openSuse (11.3)?
  
  I use Oracle 11 g R2

  You can set up a script to ensure its startup time is started:

  The startup script would be enough to ensure the ORACLE_HOME is located in the path, and then you must issue: lsnrctl start command.

  Similarly, with a stop script, make sure the path and lsnrctl stop.

• Upgrade of the Apex 3.2.1 (mod_plsql) at Apex 4.0 with Oracle Listener

  Hello
  We have a few applications in the Apex 3.2.1 (i.e. mod_plsql) which have not been displaced in Production yet. We intend to move to Apex 4.0 with Oracle listener as soon as they are available (we don't want turn on any web server mod_plsql). What will be the migration process? My apps work and look the same when I opened the Apex 4.0? All the features, formatting, etc. will be lost?
  I heard that there is a Migration Wizard, but there is no information available.
  
  When Apex 4.0 and Oracle Listener comes out? Summer 2010?
  
  I would be recognizing all of the information you have on this subject.
  
  Thank you

• question related to the Oracle documentation

  Hello

  I have a small doubt. Y at - there no standard doc Oracle who discuss about the standard RDBMS concepts like standardization, codd rules etc.

  See you soon,.

  Suri ;-)

  In my humble OPINION, include the best way to understand the concepts of data modeling.  I don't know that all of the Oracle documentation covers this area to the extent, but I found some books that give examples of explanations.  These are old classic books, but the theory has not changed.  The first two are good for designing OLTP and the last of them is good for data warehouses.  OLTP books are CASE * method entity relationship modeling by Richard Barker and The Data Model Resource Book by Len Silverston.  Both give a lot of examples with good explanations.  The third is the Data Warehouse Toolkit by Ralph Kimball.  Not everyone will agree with the logic, because there is room for interpretation when it comes to design concepts.

• Oracle Listener services

  
  Hi, I am currently working on what the content of LSNRCTL STAT is actually showing me

  In my case the summary of this command shows me

  Summary of services...
  Service '+ ASM' a 1 instance (s).
  Instance '+ ASM1' READY State, has 1 operation for this service...
  Service 'RAC1DB' has 1 instance (s).
  'RAC1DB1' instance, State LOAN, has 1 operation for this service...
  Service 'RAC1DBXDB' has 1 instance (s).
  'RAC1DB1' instance, State LOAN, has 1 operation for this service...
  The command completed successfully
  

  Q1. "Of SERVICE" above means it's Service Oracle aka Oracle database Service, which has been registered by the listening port?

  Q2. Can a Service cause more 1 Instance and under what circumstances?

  Q3. What exactly is the Service for the instance manager and how is it related to the Oracle function?

  Q4. Can an Instance cause more than 1 Manager of Service and under what circumstances?

  any help appreciated,

  Jim

  Hello

  Q1. "Of SERVICE" above means it's Service Oracle aka Oracle database Service, which has been registered by the listening port?

  Yes these are the DRH regestered a database services or services defined statically in listener.ora

  Q2. Can a Service cause more 1 Instance and under what circumstances?

  Yes, generally in the CARS (several instances of all access to the same database). You may have also several databases offering the same service (with replication, for example)

  Q3. What exactly is the Service for the instance manager and how is it related to the Oracle function?

  Service managers are the way to connect to the database. The listener redirects the client to it. It can be a dedicated process, or a dispatcher.

  Q4. Can an Instance cause more than 1 Manager of Service and under what circumstances?

  Yes. For example you can have one dedicated and shared before. You see them with lsnrctl services

• Oracle listener does not not on vmware server 2 guest OS Centos

  I write here because I think that this problem can be related to my network on the host vmware server setup 2 OS.
  I installed Oracle 11.2.0.1 on Centos 5.5 64 bits in a guest VM with a Windows 7 64 host OS. The Centos operating system runs well and the Oracle database that I created works fine locally (i.e. from a terminal in the vmware console or telnet/SSH window). The networking of virtual computer is set to bridged and I can ping the VM or ssh on the virtual machine to any other machine on the network.  However, I manage to tnsping database from any other machine on the network. When I try to tnsping from windows (with the input of appropriate tnsname) machine, I get a TNS-12541: TNS: no listener. When I try to tnsping from another Linux environment (with the appropriate tnsnames entry), I get the following:
  $tnsping demo

  Here's my tnsnames entry in the linux environment from which I will carry out the tnsping (192.168.1.74 is certainly the IP address):

  I must admit to be a bit confused about the 2 separate managers and the 'demoXDB.localdomain '.

  I copied the file listener.ora to a similar environment that works correctly, stop and then restart the listener, checked my repeatedly tnsnames entries etc. I wonder if the problem may be related to the fact that this environment runs in a virtual machine. Maybe some special network configurations are required for the NIC VM - I solved many problems of sqlnet over the years, but it baffled me. Any help is very appreciated.

• AutoConfig questions with other Oracle homes

  Hi all
  
  My sight:
  (1) oracle Apps 11.5.10.2 on Node1.
  (2) DB oracle 10.2.5.0 on node2 + Oracle 11 g. Tg4msql (works well).
  
  Due to certain requirements of patch, we applied a rollup of HR about 550 M, we run Autoconfig on nodes of DBNode/APPS, Patch applied successfully, improved features.
  
  Question:
  May be due to the configuration entry, automatic Tg4msql DB (tnsnames.ora) got deleted and the Tg4msql listener begin also using the DB listener.ora file. and we get the following error.

  Unable to retrieve text of NETWORK/NCR message 65535
  ORA-02063: preceding 2 lines from DBLINKTEST

  Entry dg4msql checked and added in DB (tnsnames.ora), set Tg4msql environment, started listener, listener goes again to DB (listener.ora), then set TNS_ADMIN and power Tg4msql listener, listener began with the correct file, even then we get the same error.
  
  All this screenplay is on a TEST server, but due to a task very urgent, I have to restore before patch backup on test server and everything works fine.
  
  Please, suggest, as I apply cumulative HR in Production very soon.
  
  Thank you

• questions of behavior to listener/notification

  I have a few questions about the behavior of listeners/notifications that I was hoping that someone had the answer to.  The end result is I'm trying to configure the system so that every day the guests I coded (global contextual modal form) don't stack up if the unit has been turned off or ignored for a series of days.  I would like a single guest waiting for the user, wherever they move to research.

  I went with the model by which this application autostart is always running (thanks to peter_strange, your posts on this topic simplified my life) but just in the background at the venue closed.  The listener that interests me is a RealtimeClockListener even though I have a listener to push both running.

  1. I saw it somewhere here that some listeners do not require the application to stay running.  What it means the System instantiates an object of the type registered?  The realtime should the app to continue running? (mine will be so it's more for the love interest)

  2. I guess that if the listener requires the application to always run it reminds the same object that registered it rather than a new instance of the object, so it seems dangerous to use some sort of Member of the Forum to follow if I already have a popup pushed.  Is it a correct assumption?

  3 I saw written somewhere on this forum when a device has a regular power down (as opposed to a battery pull) is actually still on and some processes are still running.  Does anyone know if the listener in real-time is still going and the application is notified and who responded to the questionnaire every minute?

  Thanks for any comments or corrections.

  Tim

  I don't understand what you're saying with regard to the realTimeClockListener interface.

  However I tested it myself.  I started an app with an active CCF, then press the poweroff.  Then when the computer reboots, the listener of the RTC got hit during the next minute.  So basically it hibernates.  It's a relief, I would have had to recode a number of applications...

  You are right, acceptsForeground is called before the activate, so if you want a ribbon icon, it is probably better to put up with the fact that it is visible in the background all the time.

• can we ask question related php here?

  I was wondering if it would be OK to ask the related issue of php on this forum?  There is no category or tags related to issues of the sort, but given the few people displaying their question on learning Fireworks with php question?  What is the rule for this forum on this topic?

  PHP SOLUTIONS teaches by working through a series of projects. The methods of coding that powers teaches are excellent. Many tutorials leave out important, as aspects of security considerations, but the powers provide relatively complete solutions.

  PHP PROGRAMMING is more of a text book. You can read through or choose the different sections of the chapters.

  Then down the road there are advanced books like PHP OBJECTS, MODELS AND PRACTICES

  Of course, you must also learn SQL. There are big big tomes like SQL for MYSQL, but I think you can get by learning a lot of SQL through web tutorials that cover various topics, like you need to learn.

• question related to the shared pool

  Hi Experts,

  Version of DB - Oracle Database 11g Enterprise Edition Release 11.2.0.1.0

  OS - Windows 7

  (installed on my laptop)

  Just started reading concepts DBA. I had a few questions. Please explain indetail/short ;-).

  (1) can we see the size of the Cache of the library and Cache data dictionary which are internal units of the Shared pool.
  (2) one of the advantages of the package is - when we invoke a single method, oracle loads the whole package into the buffer and for subsequent calls, it will not go to the db files. Here the buffer means library Cache. My understanding is correct.
  (3) I am able to see the two parameters shared_pool_size(value =0), shared_pool_reserved_size (value 15099494) to parameter v$. What is the difference between these two parameters.

  
  Thank you very much in advance for your help.

  See you soon,.

• Oracle listener confusion

  Sorry but I'm kinda a noob with database administration.
  
  I have a box of windows 7 with an Oracle 11 g server. I wanted to create a new listener to listen for requests on the ip address of machines. traditionally the database is down and I go to windows services and start the database and listener here.
  
  I created using Oracle Net Configuration Assistant new port listening and noticed in the list of windows services. then I deleted using the same tool.
  
  I created a new port for listening using Oracle Enterprise Manager, it is not noticed in the list of windows services, but understand that it is created dynamically? anyway... I deleted it.
  
  now, the funny is that I have a listener of the second list of windows services. I can't see it by using Oracle Net Configuration Assistant. the ususal listener in this list is started. Oracle Enterprise Manager only sees a listener and fails to start. I am able to connect to the database using sqlplus.
  
  I'm a little confused...
  
  can I remove the listener that I can't start Oracle Enterprise Manager to see if she can get rid of the additional listener in the list of windows services? Why OEMS can't see the listener has started in the list of windows services?
  
  Thanks for any direction in this area.

  is it best to remove all entries in the listener.ora files I have (if it was not clear, it is simply a workstation and has no external facilities accessing)?

  Since the V10 no listener.ora file is necessary to start or use the earpiece.

  Consider move or rename the listener.ora before starting the listener after a reboot.

  Dear Experts,
  
  In my * 11 GR 2 * database - ORCL (node 4 CARS), I remote_listener and local_listener as below:
