APEX Listener with APEX 3.0 on 11gR2

Yes, I am crazy.
We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.
The APEX listener appears to be more than just a Java PL/SQL gateway.
Is there a minimum version of APEX the APEX Listener supports?
Interested in pointers!
Rob

Hi Rob,
Yes, I am crazy.Why would that be? ;)
We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.APEX 3.0 is supprted by EPG. See the [url http://docs.oracle.com/cd/B32472_01/doc/install.300/b32468/post_inst.htm#CHDBEJDA]APEX 3.0 Installation Guide for details.
APEX Listener is capable of hosting APEX 3.0 as well, though APEX 3.0 wasn't supported anymore when APEX Listener was initially released. The current APEX release at that time was 4.0, so this would be the first version to be known as really stable, whereas you won't get any support for older releases anymore. From personal experience I know that there are now issues with APEX 3.1 and APEX Listener, so it'll probably also work with 3.0.
Concerning your database release, the minimum for APEX Listener is 10.2.0.3, so you're definetly safe on that part, though I'd recommend to upgrade as regular support for 10.2 databases ended.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.This indicates that your APEX would actually be a 3.1 and you should update you images directory.
The APEX listener appears to be more than just a Java PL/SQL gateway.It is, but this has nothing to do with your 3.1 JS files, if this is why you stated this.
Is there a minimum version of APEX the APEX Listener supports?As mentioned above, 4.0 would be a safe approach, but 3.1 will definetly work, 3.0 probably will as well. I'd recommend you find out which APEX version is actually installed on your database before you consider any upgrade operations. Run the following query as privileged user:
SELECT comp_name, version, status
  FROM dba_registry
WHERE comp_id = 'APEX';-Udo

  • Problem in integration of listener with EBS

    When i run this *"java -Dapex.home=/apex -Dapex.images=<LOCATION_OF_Image>/image -Dapex.port=<port_no> -Dapex.erase -jar apex.war"*
    Its working fine and I get a apex login page .
    But the problem is that when I close the terminal all connection are lost and given error "The requested URL could not be retrieved"
    How can i integrate listener with EBS .
    I am using
    APEX 4.1
    Database 11.1.0.7
    Application 12.1.3

    Edited by: king on Apr 17, 2012 2:59 AM

    Hello,
    But the problem is that when I close the terminal all connection are lost and given error "The requested URL could not be retrieved" That's not very surprising, as APEX Listener is running in Standalone Mode in your current scenario. If you close the terminal session that the JVM is running in you kill the JVM and hence APEX Listener.
    You could use a tool like "nohup" to detach the process you start from your terminal session. But using the Standalone Mode for a (long running) production scenario is not recommended anyway, and...
    I want to configure listener with EBS .When I start instance automatic start apex listener... obviously not your actual aim.
    So, EBS shall be your target. Shoudn't be a huge problem, as EBS comes with an OC4J Container and OC4J is one of the Containers officially supported by APEX Listener. I'm not sure if your EBS already ships with the JDK version needed, but as soon as it runs at least 1.6.0_20 it should work.
    As I've already replied to your question in {thread:id=1118604} there is a working approach described in {message:id=10069317}.
    Did you try that one? If so and it didn't work out, could you please describe the problems you've encountered?
    Thanks,

    I fear you have a fundamental mis-understanding of what a listener is and how it works, and you are starting down the road to DBA Hell.
    If you describe your real, business problem instead of problems encountered trying to implement an ill-advised solution, you will get better information. Ask the wrong question, get bad information.

  • I am using earphones, but the external audio of my mini ipad is still on. How can I turn off the external audio while listening with my headset?

    I am using earphones, but the external audio of my mini ipad is still on. How can I turn off the external audio while listening with my headset/earphones?

    Other than iMovie, GB always incorporates the audio files into the GB package. So just save or move the GB project to the external drive, and you're done - anything you import, edit or record will be saved to the external drive.

  • Please help me creating a new listener with different port#.

    I have two instances in a server. both have different homes. I want to create a seperate listener for the second one i created.
    But that is not happening.
    here i tried to give name from LISTENER TO LISTENER1 & Port# from 1521 to 1524.
    SID_LIST_LISTENER =
    (SID_LIST =
    (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME = /apps2/oracle)
    (PROGRAM = extproc)
    LISTENER1 =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (ADDRESS = (PROTOCOL = TCP)(HOST = aixth53)(PORT = 1524))
    When I check lsnrctl status with LISTENER1 , it still shows the other instance home with port#: 1521
    Please help me creating a new listener with different port#.
    Thanks,

    It just forks a process or a thread, and that's it.And the listener is a single point of failure. Listener goes down, you can't connect to the db. That's why you need two listeners.If listener one goes down, then listener two goes down for exact same reason since it is a single executable file.I'm not playing tit-for-tat with you. Fact is, there are situations where people who are not you might want to use more than one listener.Some folks might want to jab a sharp pencil into their eye, too.
    Just because you can do something, it does not necessarily mean it should be done.

  • How can I make my projects in GarageBand sound the same when listening with speakers as it sounds when listening with headphones on?

    Hi, I'm trying to export a song that I made in Garageband using mutliple tracks and a backing track. It sounds great in the headphones and all the levels are good. But, once I export and listen with my speakers, the levels are different, but sound good once I plug my headphones back in. I'm hoping to use the song in a video that will play through speakers, so I really hope someone can help. I'm new to Garageband, so I could use all the help. Thank you for your time!

    What you describe has nothing to do with GarageBand.
    Every speaker system or headphones have their own characteristics which can be measured and documented with a frequency response diagram. That describes that some speakers/headphones sound more boomy or less "bright" than others, instead of neutral.
    There are a ton of other parameters that influence the sound:
    Playing too loud (for the amp or speakers) can introduce distortion that alters the sound even before you recognize it as (nasty) distortion.
    The same song sounds different when played back with different levels. This is a trick your ear is playing on you. It is documented in the Fletcher Munson curves.
    The acoustic plays a major role. With headphones, you eliminate the acoustic environment compared to your speaker that reacts to your room and any room resonance.
    The placement of your speakers. Putting them against the wall gives you a 3dB boost in the lower frequency range (depending on the room dimensions). Putting them in the corner adds another 3dB. Placing one speaker in a corner and the other one not is even worth.
    The list goes on ...
    People spend their money on all kinds of plugins and often forget that the convertes like microphone (sound comes in) and speakers (sound comes out) are the most important components (besides your ears). Investing in good speakers is a good start. When buying headphones, make sure they are real headphones and not fashion accessories like Beats.
    Hope that helps

  • Could not start the listener with a domain user

    Hi all,
    I am working on Windows 2003 with Oracle 10.2.0.2 !
    With user "local system account", I can start the listener and I have no problems!
    after chaning the user that runs the listener from local system account to a domain user, I cannot start the listener again!
    (for the oracle service itself for the database, is it possible to change the user from local system to that domain user without problems)
    attached the error message when starting the listener with cmd.
    by starting the listener with the restart of the windows service, the listener crashed down after a few minutes
    do I have to set additional permissions for that domain user?
    thanks in advance

    The most important is the tns-12560 error message, this means that an unsupported protocol exception was raised. Assuming you are using the same environment configuration when starting the listener with the local account and starting it with the domain authenticated user, then it has to do with permissions. Both the local administrator account and the domain authenticated user must belong to the ORA_DBA group, otherwise the user won't have enough privileges to start the listener.
    On the other hand, make sure the sqlnet.ora file includes this line:
    SQLNET.AUTHENTICATION_SERVICES= (NTS)
    If you use a domain user name, log on under a domain with username and password which has administrative privileges on each node

  • Oracle Options licensed 1:1 with Oracle Ent. Edition 11gR2 or by Instance?

    Are Oracle Options licensed 1:1 with Oracle Ent. Edition 11gR2 (e.g. by CPU core multiplier) or by number of database instances on a host? In other words, if I need to purchase two Oracle Enterprise Edition licenses for a single host, do I need to purchase the same number of Oracle Option licenses (again, based on a CPU core multiplier). Or by the number of Oracle database instances installed on that host?
    Anyone have a link to an official Oracle options licensing document that spells this out? Found one for 11g but it didn't get down into the weeds, saying if there was any difference between # of licenses required for an Option vs. a license for Oracle Enterprise Edition itself.
    Requested Oracle option licensing reference

    They are licensed 1:1 with EE, so 4 EE licenses means 4 Partitioning Option licenses, etc.
    It is in the Oracle Store.

  • SQL Always On - Group Listener with a Private IP ?

    Hi,
    I read the tutorial on how to configure SQL Always On in Azure.
    I saw that we need to configure the group listener with an Public IP. 
    I also saw that SQL servers must reside in a different Cloud Service.
    A reason why is because Azure does not support direct server return.
    What is DSR ?
    To help me understanding, is someone able to explain me this situation :
    What would happen if I configure group listener with a private IP and I put all my servers in the same cloud service.

    Actually, I know what is DSR. 
    During the initial connexion, the client talks with the group listener and then redirect you to the active server. Afterward, you have a direct connection with the Active Server.
    Why is it not supported ? 
    Why having a public IP instead of a private IP resolve the issue ?
    This quote from Microsoft : 
    The client application must reside on a different cloud service than the one that contains your availability group VMs. Azure does not support direct server return with client and server in
    the same cloud service.
    Does it apply only with a public IP address ?

  • Re-registering a listener with an instance

    What are the options for registering a listener with an instance? Obviously you can restart the instance, but what options do you have if you want to reregister w/o restarting the instance?

    as SYSDBA, execute
    ALTER SYSTEM REGISTER;
    Minor correction in your terminilogy ... the instance is registered with the listener, not the other way around. By registering the instance's availability to the listener, the listener then knows it should be listening on behalf of the instance (or service).

  • APEX Listener with Free environment

    Hi,
    I was going through APEX Listener Installation guide and found that the supported installations are
    *1) with WebLogic*
    *2) Glassfish &*
    *3) OC4J*
    All of the above are associated with licensing cost. Is there any free installation scenario? As 11gXE is free to store upto 11GB of user data, I was thinking to install it with Glassfish for my small application which is not expected to have 11GB of user data over the next 4-5 years. Today I had a chat with one of the local Oracle Sales guy and I found that licensing cost is huge for Glassfish.
    I don't know whether standalone APEX Listener will serve the purpose of having my application available over the internet. Please forgive me; I am a novice in the field of networking.
    Could you please provide me the details of the free or low cost alternatives of the above scenarios? One option I know is to go for hosting services for low cost. But to me that is also huge.
    Any kind of help is appreciated.
    Thanks,

    Supported in this context is supported by Oracle in that you can open an SR with support.oracle.com or not.
    ApexListener runs on most J2EE Containers. Free ones include GlassFish Community Server and Tomcat. ApexListener runs on GF as well as Tomcat, but you cannot run to Oracle Support if you have an issue. You have to seek help here, on this forum, if you cannot resolve things yourself :(

  • How to Install & Migrate APEX 4.2x on 11gR2 database.

    Hi All,
    What is the best way to migrate APEX software and Applications FROM APEX 4.1.1.00.23 on 10g TO APEX 4.2.1.00.08 on 11gR2.
    I have enabled APEX 3x with Embedded PL/SQL Gateway on 11gR2 database. The older version APEX4.1 is uses HTTP server.
    Anyone’s help is much appreciated.
    Regards

    The best way (I had problems with this last week), is to go Oracle Support (do not use the upgrade patch from OTN), and download patch #14732511 from Oracle Support. This will automatically upgrade and migrate your Apex applications to the current 4.2.1.00.8. It should take around 15-30 minutes, depending on your hardware. The one I tried using from OTN wouldn't run, and the supposed upgrade would finish in about 15 seconds.

  • Restart Admin Login Credentials in Apex 4.0 & Oracle 11gr2

    Hi all,
    We face a major issue. We are unable to connect our admin account for some unknown reason. We keep receiving the following message "Invalid Login Credentials". We tried to change the admin credentials with sqlplus.
    We tried the usual procedure "apxchpwd" successfully, but we still cannot log in.
    We then tried to create a new admin2 account with the following pl/sql block.
    SQL> connect APEX_030200 as sysdba
    Enter password:
    Connected.
    SQL> begin
    2 wwv_flow_api.set_security_group_id(p_security_group_id=>10);
    3 wwv_flow_fnd_user_api.create_fnd_user(
    4 p_user_name => 'admin2',
    5 p_email_address => '[email protected]',
    6 p_web_password => 'admin2') ;
    7 end;
    8 .
    SQL> /
    PL/SQL procedure successfully completed.
    SQL> commit
    2
    SQL> commit;
    Commit complete.
    SQL> alter user APEX_030200 account lock;
    User altered.
    SQL> quit
    We cannot connect with either admin & admin2.
    Any good idea?
    Roger

    Hi,
    I'm not expert on this area, sorry.
    I would check what like FLOW% and APEX% users there is in database.
    Also query DBA_REGISTRY what is current/valid APEX version.
    Then try again with correct APEX versions scripts reset ADMIN password.
