Oracle HTTP Server internal heartbeat process issue

Hi All,
I am having an Oracle HTTP Server configured in the front of Weblogic 11g. I just noticed that
in my HTTP Server access.log, there is an incoming new entry every 20 seconds like this,
127.0.0.1 - - [19/May/2010:08:09:57 -0400] "HEAD /index.html HTTP/1.1" 200 -
127.0.0.1 - - [19/May/2010:08:10:17 -0400] "HEAD /index.html HTTP/1.1" 200 -
127.0.0.1 - - [19/May/2010:08:10:37 -0400] "HEAD /index.html HTTP/1.1" 200 -
It appears that it is an internal background process in HTTP server that does this.
Does anybody know what this process is and how I can stop it or just stop it from adding this entry to the log?
Thanks,
John Wang

Roberto,
I checked the file opmn.xml and could not see anything related to this. However, I did find a link which addressed the issue and provided a way to stop it from writing the record in access.log.

Using php with oracle http server

Hello folks
This question might have been answered on this forum, but i haven't found it yet.
Is it possible to integrate php into the apache server that is supplied with the oracle (9.2) database, the so called Oracle HTTP Server?
What technical issues are to consider and how do you do it on linux in that case? (SLES8)
Is there any support issues to consider if somebody modifies this oracle supplied http server?
Looking very much forward to some help...
Regards,
Christian

Weblogic certificate is not being authenticated in Oracle HTTP Server

I am using Oracle HTTP Server with SSL and mod_proxy set up trying to pass a url through to the weblogic server. I start with my OHS url in the browser and the proxy is switches to the url to weblogic but I get the following error on the OHS side:

On the OHS side I have all the certificates needed so SSL is working properly. The weblogic environment is currently working fine with other webgates, but those are apache and we are trying to switch to OHS.
Can OHS use mod_proxy to connect to weblogic or do I need to use mod_wl_ohs?
Does anyone see anything wrong in my ssl.conf file in regards to the proxy section.
Thanks in advance.

In summary:
You need to create a new wallet with CSR (certificate signing req)
Send this to your certificate authority and get the signed server certificate.
Now import the signed server cert and the trusted root cert in to the wallet that you created newly.
Modify ssl.conf to point to the new wallet location.
To create wallet refer to : http://docs.oracle.com/cd/E25054_01/core.1111/e10105/wallets.htm#CHDGIJDC
Further reference: http://docs.oracle.com/cd/E25054_01/core.1111/e10105/sslconfig.htm#CBDGIJDF
Dont mind if this doc is 500 pages ;)

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

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.

Can Oracle HTTP Server 2.0 be installed with Oracle App Server 10.1.3.4.0?

Or I guess a related question is what version of apache comes with the latest App Server Patch Set (10.1.3.4.0)?
We are running OAS 10.1.3.3.x and we are having issues with URLs that end in a number but which have query parameters at the end.
E.g. http://<stuff_here>/1?type=table&format=html
The URLs come from REST-ful GET operations. It seems like the HTTP server just ignores the query parameters completely.
When we run against stand-alone OC4J which includes an embedded HTTP server, such URLs work as expected.
We are hoping that perhaps the latest patch set for the full Oracle Application Server 10g will overcome this issue.
But if we need to move to a later Oracle HTTP Server (like the one that comes as an option for the Oracle 11g database installation) we would be willing to do so.
Comments related to this are welcome.
Thanks
Jim

Hi,
Does anyone have experiece getting Apex working with secured BI publisher?
The error I am getting when PDF printing from Apex to BI pub is:
"ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.
Error failed
OK "
Please note, network services in 11G are already configured; thus I am able to print from Apex to non-secured BI pub.
Thanks,
Jed

Re-install of Oracle HTTP Server in a configured environment

OS: Oracle Enterprise Linux 5.5 64 bit
Hyperion: v11.1.2.0
Web Server1: SharedServices, Calc, EAS, APS, Planning installed and configured. They are working from URL and clients.
We ran into issues with Workspace configuration. If we have to re-install Oracle HTTP server on the web server, will it affect the current configuration adversely? In other words, do we need to start all over again?
Has anyone else run into similar or related issues? How were you able to resolve it?
This is related to another thread I have on this forum. It is related but these are different issues and we are trying to see how we can proceed while waiting for support to respond.
Configuration of Workspace failed
Any thoughts/ suggestions?
Thanks,

How to call webservice through Oracle HTTP Server

I have cluster of three Managed Servers. They are behind a Oracle HTTP Server. I deployed a web service to the cluster. When calling web service, I got the error. The error is that the client of web service can not directly access the Managed Servers.
The error tell that it can not access http://webapp01:7003/webservice/HelloWorld?WSDL
Where webapp01 is the host name of a managed server.
Is there a way that web service return the result to HTTP Server and HTTP Server return it to web service client.

1. Before you invoke the WebServices from client program, I guess you may have already generated the webservices client jar for the WSDL that is deployed using sun jdk "wsimport" command or bea's clientgen ant task. At this time, what is the wsdl url you gave. In the generated client jar file you should see .JAVA files also. Check the Service related .java file and check the WSDL URL in that file. If it is using weblogic servers managed server host and port, then the problem you see is obvious.
2. To fix this, you re-generate the webservices client jar file again this time giving the http server host and port instead of weblogic host and port. I am hoping you already modified httpd.conf file to accept the webservice url pattern. Check the .JAVA file generated for service to see the WSDL URL that is having inside.
3. Another approach is on your client side, before you invoke any operation on WebService, you will be first getting Service object, then Port object and invoke methods on Port object. When you get Service Object, you can pass the WSDL URL as one parameter and ServiceName (QName) as second parameter. Most of time we use default constructor without any parameters to get Service object. But you can use other constructor and pass 2 parameters. The WSDL URL will have HttpServers host and port, and rest of the url for wsdl will be the same.
In our env, we have similar requirment. SOAP BPEL Process WebServices are deployed on WLS 10.3.1 on a Cluster with 2 ManagedServers. We have Apache Proxy in front of this Cluster. All our WSDL requests goes to Apache host and port + wsdl url. This inturn goes to one of the managed servers at a time in round-robin. This is working. In httpd.conf we gave "MatchExpression / " so that any request from apache will go to cluster.

Can you run Embedded PL/SQL Gateway and Oracle HTTP Server at the same time

Hi,
I know this will sound a bit odd but their is a business case for asking this. Can you run APEX via the Embedded PL/SQL Gateway and the Oracle HTTP Server at the same time? Would their be any security/stability/etc issues I'd need to worry about? I know that I'll need to run them on different ports.
Thank you,
Martin Giffy D'Souza
[http://apex-smb.blogspot.com/]

I think I've done this in the past. Theres no technical reason why you can't do this as far as I know.
I can't remember if I used different ports or same port.

Slow performance with oracle http server connecting weblogic

Any pointers are highly appreciated.

Shannon,
The OHS + Weblogic installation, just means you will have an admin server, with Enterprise Manager that can manage your OHS instances. That being said:
1 - You don't have to extend any domain, since the only thing OHS will need is an Admin Server with Enterprise Manager.
2 - I (myself, I don't speak for Oracle here) have a personal preference of having stand alone OHS. If you don't know how to work with httpd.conf and mod_wl.conf, I would suggest installing a separate domain only for it, that way you can keep the weblogic turned off, and turn it on only when you need to edit any configuration.
Thanks

Error starting up ApEx's Oracle HTTP server

The modplsql/logs directory is completely empty.
The stop and start of the http server is clean - no errors reported.
The main log in Apache/Apache/logs directory is not big, since it is a brand new install of the http server. Here is the complete log:

New Oracle HTTP server install unable to host remote HTMLDB.

Hi all.
I installed the Oracle HTTP Server from the Oracle 10G Release 1 companion CD on a Mac Powerbook running the Tiger OS. I have a CentOS Linux server on my network with Oracle 10G R2 database running that I've installed HTMLDB 2.0 on. I can not seem to get the HTTP server to serve up a front end to my HTMLDB. I can connect and log into the Oracle Database from the MAC using SQLPlus using the HTMLDB_PUBLIC_USER account and password.
Here is my dads.conf file:
Alias /i/ "/oracle/product/10.1.0/db_1/Apache/Apache/images/"
<Location /pls/htmldb>
SetHandler pls_handler
Order deny,allow
Allow from all
AllowOverride None
PlsqlDatabaseUsername HTMLDB_PUBLIC_USER
PlsqlDatabasePassword HTMLDB
PlsqlDatabaseConnectString CentOSServ3:1521:htmldb ServiceNameFormat
PlsqlDefaultPage htmldb
PlsqlDocumentTablename wwv_flow_file_objects$
PlsqlDocumentPath docs

PlsqlAuthenticationMode Basic
PlsqlNLSLanguage AMERICAN_AMERICA.WE8MSWIN1252
</Location>

Here is the errors I'm seeing on the error log:

It keeps giving me the error for the Language, but I've changed the PlsqlNLSLanguage serveral times to other posted values I've found and other postings and I still get that error.
Has anyone else worked through this or may have an idea how I can get this working?
Thanks,
Mike

Also, here is the error I get when browsing to : http://localhost:7780/pls/htmldb/htmldb from the HTTP server.

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Oracle HTTP Server and Node Manager

Hi,
I installed Oracle HTTP Server with Node Manager. I set "CrashRecoveryEnabled=true" in the nodemanager.properties. It works fine when I reboot the machine, but when I kill the root process (kill -9), the new process can not be started as the previous process does not have enough time to die and still uses the ports. I tried to run "nmGenBootStartupProps" in wlst, or set the
RestartMax=2
RestartDelaySeconds=5
variables in "[domain_name]/servers/[server_name]/data/nodemanager/startup.properties" - no success.
Any ideas, how to set the number of retries and the delay between restarts?
Versions:
Oracle HTTP Server: version="12.1.3.0.0"
java version "1.7.0_79"

To deploy your FMX you need AS 10.1.2 Forms installed, and then you can use AS control or Forms server configuration file.
For more information regarding FMX deployment, refer to http://download.oracle.com/docs/cd/B14099_19/web.1012/b14032/toc.htm

Oracle HTTP Server and mod_plsql

Hi there,
I have a problem using HTML DB on a small network. LAN consists of two computers with Windows XP Professional, Service Pack 1. Server has two NIC. One connected to the local internet provider (PPPoE) with TCP/IP set to "Obtain an IP address automatically" and second network adapter (for the LAN) with TCP/IP address 192.168.0.2. Second computer has NIC with IP 192.168.0.3. The server is set with HTML DB 2.0. There is NO ANY problem if I work on it as stand alone computer - second network adapter disable!
The problem arises if I connect the second computer and then start HTML DB by http://localhost:7777/"503 the service is temporary unavailable", emagent is down, DBconsole service is not active anymore, etc. Apache or Oracle HTTP Server is up.
I have found, after several days of troubleshooting, that the problem might be in httpd.config file. If somebody have experience in similar networks or Oracle HTTP Server settings please, give me advice or send httpd.conf file as an example.
Please help me!
Konstantin

Hi,
If I disable the network adapters and restart the computer, then connect to the HTML DB or my application, everything is OK. Then enable connection and I can work from both computers!

The dad.conf is empty because I am using marvel.conf. I just checked the rules to build such file. Listener uses as host name - computer name (in my case koncomp), but in all config files Oracle HTTP Server uses name localhost or 127.0.0.1. That is the reason for SYSMAN to make too separate folders in Oracle home named LOCALHOST_instancename and hostname_instanceename.

It goes down all the times when the problem arises.

Oracle Application Server 10g thread stuck issue.

We are having,
Oracle Application Server 10g [10.1.3.1 + 10.1.3.4patch] along with Oracle Http Server 2.0
Now there is a issue of thread stuck [some application threads taking longer times] due to which the application server is unable to respond and sometimes it reinits the oc4j instance.
=> Is there any setting to increase the Thread Stuck Time in OAS.
=> Is there any setting to stop the auto reinit of oc4j instance.
=> Does the auto re init of oc4j get logged in opmn.log as well as in service.log.
It will be really helpful if any advice on the same.
Thanks in advance...
ManojC

Look in httpd.conf file anything that is like thread in there you will find a simple description of the Directives.
Greetings.
