Huge success in Oracle HTTP Server for Application Apex

Hello


I've been running several applications in the same database in Apex 4.2.2. I use Oracle HTTP Server 10.2 for web access to customers. I have 4000 users in systems, but at the same time can be logged 500. Server Web is in DMZ, and database server's internal network. We notice that we conduct page huge hit in the system, very high. I noticed a client IP had 44 000 visits in one day and on a daily basis any number of access is 500 000 to 600 000. That is for me, it's huge. This huge success makes the firewall close the connection to the web server. This disturbance is causing the company a lot.


I would like to know how Oracle Apex communicates with the web server and clients, is the mechanism of Oracle Apex which causes this huge success or is it for external cause, such as a DoS attack or something like that. I'm really exhausted with it. Don't know what to do. Help, please

Hi I have kind of a resolved / by past the problem. Now, I have no connection to the bottom of the problem. The problem was. Subdomain (say myapp.testlab.com) of my app had a single IP address, router treated the huge success of the same IP address as a threat and that's why router blocked the real IP of this subdomain. We did it, we asked our dns provider to add a few more (5) IPs for the same subdomain. Now, as dns selects a single IP among 5 fps in alternating single IP does not get as much success as to be blocked by the router. It works better now. Cordially Hasan Al Mamun

  • Oracle HTTP server with multiple apex bodies

    It is possible to have an Oracle HTTP Server installed in a different machine.
    and apex mounted databases in the different machines?

    Or it would be necessary to install a HTTP server for each instance of APEX?

    For example:

    Machine 3
    ___DATABASE A
    Machine 1 to Machine 2.
    BROWSER-> HTTP SERVER.
    ------Machine 4
    \___DATABASE B

    Yes, you can set several dads - pointing to bodies different machines/APEX - in a case of OSH.

  • Do we need Oracle HTTP server to host Oracle Apex?

    We are completely new to this Oracle Apex.

    Wanted to know the license part of it, before you enter into it.

    I guess Oracle Apex is free because it comes with the Oracle database license.

    (1) do we need a sort of HTTP server to host the Summit on the browser?

    (2) any HTTP server will be working with Oracle Apex?

    Don't know on what basis 'someone' advised to do (migration of ADR to OHS)?

    As the Oracle Documentation says otherwise in their comparison of the options of the web listener.

    Reference: https://docs.oracle.com/cd/E59726_01/install.50/e39144/overview.htm#HTMIG29325

    Also, I found the trend of migration of OSH to ADR and not otherwise.

    Reference:

    Personally, I prefer ADR on OSH as a server option for Oracle APEX Web and I had included in my profile of Oracle Database Developer's Choice Award 2015 for which I was chosen as a finalist in the category Oracle APEX and ADR.

    Standalone Oracle HTTP Server (OHS) is always available. To 10 gr 2 (10.1.2), you can install it off 'Application Server Companion CD' available here:
    http://www.Oracle.com/technology/software/products/IAS/htdocs/101202.html

    10gR 3 (10.1.3), you can choose the type of installation "Oracle HTTP Server" (under the "Advanced Setup" option). This will give you just SST (and OPMN) which is based on Apache 1.3. OHS based on Apache 2.0, you can install "Oracle 10 g 3 companion CD (10.1.3.x)". The CD is available here:
    http://www.Oracle.com/technology/software/products/IAS/htdocs/101310.html

  • It must for application Apex runs in mode listener Apex to use Apex listener 2.0 as a print server?

    Hello world

    I'm an Oracle Apex developer for 2 years now.

    Recently, I was in charge of search and do a few examples of how to print pdf with Oracle Apex 4.2.2 (Oracle 11 g).

    I want to use Apex 2.0 listener that standalone as a print server, we installed and we changed the configuration of the print server in the administration workspace. Then I created a report query and when I have the test report, a pdf file is downloaded, but when he opens, Adobe reader tells me that is not a valid pdf file.

    Our Apex application runs in the pl/sql gateway mode not Apex listener.

    So my squestion is: "" Is it mandatory for application Apex runs in mode listener Apex to use Apex listener 2.0 as a print server?".

    Thanks for help.

    Thanks for your reply.

    We have an apex application that already runs using EPG and we want to allow printing of the pdf in it. So, we installed the ADR offline, to use as a print server but it does not seem possible if the Apex app uses a different web server than the listener of the Apex. right?

    Thank you once again.

    You have answered your own question... If you use the EPG, then you can NOT use another product middleware or application server until you turn off the EPG...

    Why you use the EPG in production?  Oracle does NOT recommend this (see the APEX Oracle installation instructions..)

  • Not able to install Oracle HTTP Server existing Middleware at

    Hello Experts,

    I'm not able to install Oracle HTTP Server in an existing House of Middleware, Weblogic. I installed Weblogic 12 c and tries to install SST 12 c in the House, same Middleware

    I am getting error below:

    INST-07551: not all depenedent go to the installation type "Colocated HTTP Server (managed through WebLogic server)" could be found. The following prerequisites proved to be missing: em_fmc - 12.1.2.0.0

    OS: Windows 64-bit

    Installation of Weblogic using jar generic wls_121200.jar

    Please suggest about same,

    Rajesh

    Hi Renon,

    In the 12 c version, there are two supported by Oracle HTTP Server domain configurations:

    • In a WebLogic Server domain
    • An autonomous area

    If you configure Oracle HTTP Server in a WebLogic Server domain, you can manage your instances Oracle HTTP Server, Enterprise Manager Fusion Middleware control, WLST and WebLogic Server Node Manager command line interface. To configure Oracle HTTP Server in a WebLogic Server domain, you must install the Oracle HTTP Server software into an existing Oracle Fusion Middleware Infrastructure Oracle home.

    If you configure Oracle HTTP Server in a standalone domain, Oracle HTTP servers reside in a separate autonomous area, which is intended to only manage system components. To configure instances Oracle HTTP Server in a standalone domain, installing Oracle HTTP in a separate Oracle home, and there is no prerequisite for Oracle Fusion Middleware Infrastructure.

    For details, see the following documentation: installing and configuring Oracle HTTP Server, 1 Planning Your Oracle HTTP Server Installation

    My understanding is that you want to install Oracle HTTP Server in a WebLogic Server domain. This means that you must first install and configure the Oracle Fusion Middleware Infrastructure software. Then you install the Oracle HTTP Server in the Oracle Fusion Middleware Infrastructure Oracle home, and finally configure you as part of the Oracle Fusion Middleware Infrastructure field.

    Distributions of products can come from either the delivery of software Oracle or Oracle Technology Network Cloud. See the download page of Oracle Fusion Middleware, Installation and Configuration of the Readme files.

    I think that the following note will help in this task: Note 1588516.1 - high steps on how to install and configure level located at the same place (Managed) SST 12 c on Windows 7 64 bit

  • Oracle HTTP Server

    Greetings,

    I'm an EMP facility run in a development environment on a single server - Windows Server 2008 R2 64-bit.
    All goes well, until I tried to configure the Web server. In the Configurator, after selecting "Set up the Web server" only, I don't see Oracle HTTP Server in the Web Server Type drop-down list.
    So, I came to a conclusion that he had to install Oracle HTTP Server (OHS) during the installation phase.

    After reading this forum and others, I started the installation program and tried to re - install OSH. But, I noticed that it was not selectable - it is greyed out.
    So I re-uploaded the part number of edelivery.oracle.com and chilled out for the second time on my local machine. I thought that I was missing the files needed to get installed ESS.
    Then I handed in the installer market-, but the SST checkbox is always grayed out.

    How can I "force" the installation program to install the SST? Or do I need? Can I just run with IIS and life lights? (it's just a dev box)

    Any thoughts would be great. Thank you very much, Paul

    I once had a similar problem and found that if I ran the process of \ohs\Disk1\install\win64\setup.exe and pointed out the House of Middleware "D:\Oracle\Middleware\" and called the "OSH" Oracle Directory it solved the problem.
