Oracle HTTP Server as web tier for OBIEE - Best Practices?

Hi All,
A bit of a cross-topic issue - IHAC which wants to add a web tier (in a form of additional DMZ server with Oracle HTTP Server installed) to existing OBIEE installation.
Are there any best practices regarding all the security aspects - installations, ports, SSL, certificates, keystores etc. ?
Thank you in advance,
Roman

Am not using weblogic, I'm doing standalone setup
Standalone:
FMW 11g Web-Tier products are configured without a domain and administered from the command line. In this case, be sure to UN-check the selection for “Associate to WebLogic Domain” during the installation prompts and uncheck the web cache.. Only OHS is installed.
Is it possible to install sun jdk 64 bit on AIX 7.1 machine.. ?

Use oracle http server to configure mod_plsql

Hi,
I have a question.
I have already installed HTTP server using the Oracle Database10g Companion CD
on my Windows 2000 SP4.
At the end of the installation, it refers to http://<computer_name>:7777
to open the HTTP server page.
It seems work fine that it showed the Welcome page of HTTP Server and I find this
"Oracle HTTP Server is the Web server component of Oracle Application Server 10g Release 2 (10.1.2). Oracle HTTP Server is a robust, reliable Web server based on the Apache HTTP Server, version 1.3."
But I could'nt do anything of using the mod_plsql components nor another
Modules (mods) which showed in the welcome page since there is no link to such things.
BTW, I have experienced with the HTTP server previously on Oracle9i
When I open the HTTP server page, it showed links to some Modules (mods)
components such as mod_plsql, etc.
Does the HTTP Server in this version need to be configured to use the links like in Oracle9i's HTTP Server?
Or the new Oracle HTTP server does not support for this thing?
Actually, I worked on Oracle Workflow, which need the Oracle HTTP server to configure
some few things such as DAD.
Please, can anybody help me to solve this problem.
Thanks,
Buntoro

How can we debug Oracle Http Server on AIX.

Our requirement is to attach a debugger (dbx) to oracle http server on AIX.
For that purpose we need to start the OHS webserver service that is opmn in a single process mode the way we start Apache webserver by -X option.
Can anyone help how can we start OHS in single thread.

I have installed Oracle Apex 4.1 on Oracle 10g database but I want to configure Oracle HTTP Server on another Server(Microsoft Windows 2008 R2). Here I have placed Apache Tomcat 6.0 version already. Can anyone please tell me how is it possible to install and configure Oracle HTTP Server on Windows 2008 along with Apache Tomcat?Why? Installing OHS and the DB on separate servers will incur additional licensing costs.
More common confugrations would be to use Apache as a reverse proxy to an OHS+DB server, or Tomcat+APEX Listener with a DB server and not using OHS at all. (Although I understand Tomcat is not an Oracle-supported platform for the APEX Listener. For any questions on this or other Listener-related topics use the {forum:id=858} forum.)

Oracle HTTP Server 9.0.2

Can I use Oracle HTTP Server 9.0.2 for HTMLDB 2.0? Is there any issue with that version?
Thanks.

What does the error_log of the Oracle Apache HTTP server say? This is typically in the $ORACLE_HOME/Apache/Apache/logs directory.
Weird that a mutex create failed. Without the actual o/s error code that resulted, it is difficult to diagnose the problem. Anything in the Application (or Security) Event Log? Access denied seems to indicate an ACL failure of sorts.
You could also disable FastCGI - it is not very often used and APEX (mod_plsql) does not need it. The httpd.conf file (in $ORACLE_HOME/Apache/Apache/conf) can be edited to disable FastCGI.

Web Service and Oracle HTTP Server

I have a web environment with Oracle Database 10.2.0.3 , oracle http server (using mod_plsql), Oracle pl/sql web toolkit. I need to create a web service that is accessed externally which will interact with the database (select, insert, delete). Is it possible to publish a web service to the Oracle Http Server or to implement web services with the environment above

Hello,
In RDBMS 10g you cannot directly expose WS from the DB you need to use the OracleAS Web Service Runtime to do it, following this documentation:
- Developing Web Services that Expose Database Resources
This is true if we are talking about "tooling/runtime/API" but after all Web Services are mainly XML (WSDL and SOAP) so it is still possible to create by hands (PL/SQL & static files) but it is probably a long work depending of the complexity of your services.
Also, in RDBMS 11, you can now directly expose WS from the DB using the embedded HTTP server, see this Oracle 11g New Features Document
Note that before taking one approach you must take time to write up your requirement regarding Web Services eg: do I need security, which time of encoding, interoperability, ..., ... For example WS-Security that is the standard to secure SOAP messages is not (yet) supported by the Oracle 11g RDBMS Native Web Services... where when you do use the WS-Runtime you can secure the Web Service..

Down Time for Installing APEX 4.2.1 and oracle HTTP server?

Hi, all:
I plan to install APEX 4.2.1 and oracle HTTP server on 10.2.0.4 database.
Is there any down time required during installation?
I mean during installation, do I need to block users from accessing the database?
Can they do their normal data entry / inquiry?
thanks,
John
ps. There will be server backup before installation.

Hi,
Documentation says
>
3.1 Recommended Pre-installation Tasks
Before installing Oracle Application Express, Oracle recommends that you complete the following steps:
Review and satisfy all Oracle Application Express installation requirements. See "Oracle Application Express Installation Requirements".
Shut down with normal or immediate priority the Oracle Database instances where you plan to install Oracle Application Express. On Oracle Real Application Clusters (Oracle RAC) systems, shut down all instances on each node.
An alternative to shutting down the database is to prevent all users from accessing Oracle Application Express when upgrading your installation from a previous release of Oracle Application Express. Oracle only recommends this option in high availability production environments where planned outages are not available. For all other scenarios, the database should be shut down.
To disable access to Oracle Application Express when the existing installation is using the Application Express Listener, shut down the appropriate application server where the Application Express listener is deployed.
To disable user access to Oracle Application Express when the existing installation is using the Oracle HTTP Server with mod_plsql, you should either shut down the Web server or disable the Application Express Database Access Descriptor of the Web server.
For an existing installation using the embedded PL/SQL gateway, you should disable the Oracle XML DB Protocol Server by setting the HTTP port to 0. This can be accomplished by starting SQL*Plus, connecting as SYS to the database where Oracle Application Express is installed, and running:
EXEC DBMS_XDB.SETHTTPPORT(0);
Once you have prevented access from Oracle Application Express users, you should log into SQL*Plus as SYS, connecting to the database where Oracle Application Express is installed, and query V$SESSION to ensure there are no long running sessions which would interfere with the upgrade process.
Back up the Oracle Database installation.
Oracle recommends that you create a backup of the current Oracle Database installation before you install Oracle Application Express. You can use Oracle Database Recovery Manager, which is included in the Oracle Database installation, to perform the backup.
See Also:
Oracle Database Backup and Recovery User's Guide
Start the Oracle Database instance that contains the target database.
After backing up the system, you must start the Oracle instance that contains the target Oracle database. Do not start other processes such as a Web Listener. However, if you are performing a remote installation, make sure the database listener for the remote database has started.

How to isolate web applications at URL level with Oracle HTTP Server?

We have 2 machines each for oracle web cache, oracle http server and oracle application server (oc4j). We would like to host many web applications on this infrastructure. We have an issue with application/web site isolation for maintenance purposes.
We have several oc4j containers for different web sites/applications but they all use one instance of Oracle Http Server. When we need to make changes to an application/web site or introduce a new web site (URL), we change the OHS configuration and restart OHS on each of the machines.
As we have many URLs hosted on this OHS and plan to host a lot more (may be around 300), we need a way to slice and dice the URLs so that every change or any change should not need to go through a regression cycle or testing cycle for all the applications each weekend (our change window). When we used Apache earlier, we used to be able to create multiple httpd.conf (process level isolation) to cater to different applications.
We could do this with Oracle Http Server too but Oracle will not support us. I appreciate any advice or suggestion with this issue.
Thank you
Ramana

Hi Joey,
A great idea! I recently presented at a local user group meeting about my WebSockets API (see the links in my signature). I've uploaded the presentation and the demo code I gave to our UG here.
I think the barrier to entry is with needing to know the web languages (e.g. html/css/js) as well as writing your LabVIEW code. I have joined the group and look forward to seeing some interesting content on there! Certainly some demos of using AJAX to make requests to Web Services and do something with the data (e.g. display on a graph) would be a good place to start.

Hi all
That´s right, the OHS was installed with the Fusion Middleware Web Utilities installation and working fine !
The Apex application is online without problems.
Now, my challenge is to implement the security certificate (SSL) on OHS.
I´ve been read many things but I´m a little confused and looking for a specific documentation to do that.
The certificate was generated and got the especific files ( .cer / .crt / .key ) but the problem is how to configure.
Is it necessary to install another software ?
Is wallet manager must be used or just configure some files like ssl.conf ?
Thanks in advance for any help.

Companion CDs for 64-bit Oracle HTTP Server for AIX5L(64 bit) required.

I need Companion CDs for 64 bit Oracle HTTP Server for AIX5L(64 bit).
I tried to install using
as_ibm_aix_companion_101300_disk1.cpio & as_ibm_aix_companion_101300_disk2.cpio
but when i checked the files present in <Oracle_Home>/ohs/lib , they are of 32-bit.
Also i tried with Oracle 10.1.2.0.2 but still the server is installed as 32-bit.
Is 64-bit Oracle HTTP Server supported on AIX5L(64 bit) ?
If yes, then from where can i download the CDs?
Any suggestions will be appreciated.

Oracle HTTP Server for APEX3.2

I am a DBA but new to APEX.
On page 4-15 of APEX3.2 Installation Guide, it says
Install from the Database and Configure Oracle HTTP Server
This section describes how to configure Oracle HTTP Server with mod_plsql
distributed with Oracle Database 11g or Oracle Application Server 10g.
It seems that Oracle HTTP Server is neither distributed with the database CD nor Example CD. Am I right?
Also, can I use HTTP Server bundled with OMS to serve as HTTP Server for APEX? Will that impact Grid Control?
EPG is not considered.
Thanks,
Kevin

Hi
When using Grid of course, there is a HTTP server
When having the Rdbms, you need the companion cd or use one of products that has already HTTP server .... ( Example ; IAS, etc )
Kind regards,
Iloon

How to create a service for Oracle HTTP Server

Hi,
I hope someone can help me.
I would like to create a service for an Oracle HTTP Server.
We are running APEX 3.2 on an 10.2.0.4 database (not XE).
We have a Windows XP system.
To run APEX on a 10g we need the HTTP Server.
Unfortunately no service was created while the installing of the Oracle HTTP Server.
How can I create a service later. After the installation.
I know that you can create a service with Instrsrv.exe and Srvany.exe. But I dont know wheather I can use this in this case.
I need an .exe file for that.
The HTTP-Server has the opmnctl.exe.
But I have to write opmnctl.exe startall when I start or opmnctl.exe stopall when I want to stop it . How can I realize that in a Service?
Thanks for your answer
Jens

How to set -Xss or ulimit for Oracle Http Server

Hi,
We are facing Out of Memory Error in OHS 11g in our cluster environment. Where I can see below statements in http log file:
# There is insufficient memory for the Java Runtime Environment to continue.
# Cannot create GC thread. Out of system resources.
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.
# Out of Memory Error (gcTaskThread.cpp:46), pid=17956, tid=140591807985408
When I run the ulimit command on machine, stack size is showing as 10MB:
Result:
[oracle@XXXXXX bin]$ ulimit -a
core file size          (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 1031958
max locked memory       (kbytes, -l) 3500000
max memory size         (kbytes, -m) unlimited
open files (-n) 131072
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 131072
virtual memory          (kbytes, -v) unlimited
file locks (-x) unlimited
Setting the stack size to 512KB or 256KB might resolve the problem.
I tried setting ulimit -s 512 in my user bash_profile. and ran ulimit -a , then it is showing as
stack size (kbytes, -s) 512
If I set at user level, does it have any impact? Or we should set at JVM level using -Xss
Can some body tell me where can I set -Xss for Oracle HTTP server 11g?
Regards,
Vidya

Hi Marco,
I believe you'll need to setup a MX record under 'More Actions' for your domain in Site Settings / Site Domains.
Select the option "Use another external service for email" and enter your primary mail server's hostname at priority 10.
Think you can repeat this step for your secondary mail server (priority 20) if you have one.

Set up Oracle HTTP Server for a particular IP address

How do I set up Oracle HTTP Server to allow access control based on a particular IP address to certain CGI Scripts if a site is a local site?
I have tried this in httpd.conf file but it does not restrict a particular IP address (say 10.1.2.4) in my home network (consists of 3 PCs). 10.1.2.3 is the IP address of node where OHS is installed. I access my OHS from client like this http://10.1.2.3:7777/cgi-bin/printenv
ScriptAlias /cgi-bin/ "C:\oracle_home\Apache\Apache\cgi-bin/"
<Directory C:\oracle_home\Apache\Apache\cgi-bin>
AllowOverride None
Options None
Order Deny,Allow
Deny from all
Allow from 10.1.2.3
</Directory>
Note: - I have not made any changes in the default configuration of OHS.
Any help for a student like me will be highly appreciated.
Regards
Rajesh Kumar

No the idea is not to disable the signature. The reason why I wanted you to locate the specific block/deny was to make it easier to fix it. I would still recommend to use the Event Action Filters only to exclude the host and not disable the signature altogether.
That said, there are some signatures that "according to the documentation" cannot be excluded using event actions like Sweep signatures. These signatures have a field for Source/Dest IP built-in to exclude specific hosts. HOwever to be honest I could get event actions to work perfectly with event actions on our customers ;), so it could be an old restriction still mentioned in the docs.
Lastly, you only disable a signature when you are absolutely sure that you are not running the Software/Application/Service on your network. For example on one customer we would frequently get VPN 3000 COnc. HTTP attack signatures fired for internet traffic, and since there is no chance to add any VPN3k on this network (its already End of Sale), I disabled this signature.
