CF8 install problems on linux server

Really some basic install questions as it seems this should
be simple enough, but I am a little confused with the jrun part. I
am running on a Cent OS 5 server, the install I assume is the
multi-server. It was installed to the default /opt location and I
have both the coldfusion and jrun folders. I changed the apache
connector to work which gave me the all good, but I have the
following.
I can hit the admin page
http://server.domain.com/CFIDE/administrator/index.cfm
( no ports ). But when I try to load one of our pages I get;
[Tue Mar 10 11:21:00 2009] [notice] jrApache[18561: 13457]
JRun will not accept request. Check JRun web server configuration
and JRun mappings on JRun server.
I am still confused if I need to start cf
(/opt/coldfusion8/bin/coldfusion start), AND start jrun
(/opt/jrun4/jrun -start cfusion) but things just won't work, and I
think I need a high level look 1st. Do I need that above jrun, if
so how to setup, etc. If I run the ./jrun -start cfusion then try
to run the cf-connectors.sh I get;
Configuring the web server connector for ColdFusion 8
(multiserver)
Running apache connector wizard...
=======================================
There was an error while running the connector wizard
Connector installation was not successful
=======================================
So any push in the right direction will help. I can provide
anything, tried to be as descriptive as I can, but let me know.
Thanks

I would guess you have ColdFusion installed, but your web
server has not
yet been configured to do something about it. You need to
configure
your web server to know that when it gets requests for
ColdFusion
resources, such as .cfm, .cfc. and .cfr files, it needs to
pass the
request off to the ColdFusion engine, not just serve the
files to the
client as a text file.
You should be able to find the information you need by
searching for
information on wsconfig and ColdFusion web server connector.
These two sections of the documentation are all about this
topic.

How to install PEAR on Linux server

Hi
I have PHP installed on one linux server and developers are using it already. I have been given the task to get the oci8 (oracle connectivity) done on this same server. I can not do the reinstall of whole PHP again. During the install of OCI extention I got many errors for missing PEAR files.
So I went through the PEAR document and found "php go-pear.php" command to install the PEAR package. This command fails with below error.
download of http://pear.php.net/get/PEAR?uncompress=yes failed: Failed to parse address "" (0)
The problem is this Linux box does not have direct internet connectivity so I had to download all the required packages as per go-pear.php on my local machine and I am FTPing them to this linux box. I have kept the "PEAR-1.8.1.tar" file in the same directory where go-pear.php file exists but still the above command tries to download it from internet.
Could you please tell me how can I overcome this problem. Please let me know if there are any RPM's that I can use to install PEAR rather that "php go-pear.php" command.
Thanks

Hi CJ.
It has been more than 4 weeks that I am strugling to get PHP-Oracle work on my system. You are the only hope right now. I have gone through so many articles and white pages that I am totally confused and starting to hate PHP or actually Suse Linux. :-)
Below are the details of my system.

Question.
1) Do i have to upgrade the PHP version to the latest to get OCI8 configured?

3) If the upgrade is not needed, how can I configure PHP to use OCI8 to connect to database?

Oracle9i Install problem on Linux 7.2

While running runInstall and trying to create a General Purpose DB the install
of software goes OK. During the DBCA I get an error message at 46%
ORA-03113: end of file on communications channel
Any ideas ?

What is the name of your installer file? have you downloaded the one for
Linux OS?
make sure you FTPed the installer file in binary mode.

CF11 install problem on WIndows server 2012 R2

We have a new install windows server 2012 R2 with a new install CF11 standard installed on C drive. Everything is 64bit. The CF administrator site and login works fine. cfm files will not serve up in the default directory, but IIS shows htm files fine. CF administrator runs fine.
Web Server Config tool will only show "None" in the IIS Web Site box. The usual CGI, APS, etc have been installed on IIS. In fact IIS and CF11 have been reinstalled. wsconfig.exe manual run shows no errors.
The problem is that any call to a cfm template results in an error (html pages serve fine):
HTTP Error 500.0 - Internal Server Error
The page cannot be displayed because an internal server error has occurred.
Detailed Error Information:
Module       IsapiModule
Notification       ExecuteRequestHandler
Handler       cfmHandler
Error Code       0x8007007f
Requested URL       http://localhost:80/default.cfm
Physical Path       C:\inetpub\wwwroot\default.cfm
Can anybody give any suggestions for troubleshooting? No logs seem to show any information that helps.

Fixed the problem......... it is not a CF problem alone but and mostly an IIS problem ....
1) remove IIS completely...... including the inetpub directory..... remove .NET Extensibility from server manager under Application Development if inetpub in use error is present... inetpub has to be deleted.
2) reboot
3) reinstall IIS and enable all the usual stuff, ie, CGI, ISAPI, .NET, ASP , WebSocket Protocol, etc under Application Development
4) restart IIS and CF
5) Set Web Server Config to "All"
60 restart IIS and CF
The trick to completely reinstall IIS and that is only done if you can delete the inetpub folder under root drive.

There are a couple nasty things in your code (not that your coding would be wrong).
Maybe better look into jakarta commons,
http://jakarta.apache.org/commons/fileupload/
There are minor issues like \r, content length/chunk mode, //home,
path names, bytes-to-String without encoding. Also officially "--" is not allowed to occure inside an HTML/XML comment, hence some people use .

Install AUSST on Linux Server?

In the AUSST installation video, Karl mentions that AUSST can be installed on Mac, Windows, or Linux. Does anyone have any idea of how this is done? I have pulled the python scripts from the Mac package and attempted to run them, but have had no luck in doing so.

EDIT: Added vimeo video tutorial. http://vimeo.com/57973290
Okay! I'm working on OSX. Trying to get this on Ubuntu Server.
I am still waiting for Adobe to get back to me but in the meantime I have done some tinkering.
Basically, you just need to copy the Resources folder inside the AUSST tool (Show package contents).
Click on "Show Original" to anything that looks like an alias inside and replace with the original content. (I think this is the "includes" folder and the "config" subfolder under lib).
From there you have to edit the main AdobeUpdateServerSetupTool2.0.py and delete line 33 "from version import *", you also have to remove the "%(ToolVersion)" on line 1351. I just discovered this from trying to run python and getting traceback errors.
From there, I think you can use the tool like normal. In ubuntu server I ran a command in bash like "python AdobeUpdateServerSetupTool2.0.py --root=/home/serveradmin/test/" (where "serveradmin" is MY username, and "test" is the folder to store the downloads, your config may differ).
I can confirm this then gets the files downloading. I am not at a stage where I have tried setting up apache to host this out. Just a start!
Ideally Adobe would have had MUCH better documentation if they mention it can be run off Linux in their Enterprise video!
I have also made a video I can post to vimeo showing these steps, should anyone request!
Best of luck!

Jmf instalation problem on Linux

On my slackware 9.0 with java sdk1.4.2_04 I've tried to install jmf 2.1.1e. I've downloaded and executed the bin file. I've added the CLASSPATH=.:/usr/lib/java/JMF-2.1.1e/lib/jmf.jar and the LD_LIBRARY_PATH=/usr/lib/java/JMF-2.1.1e/lib but I can't run applets using appletviewer unless I use appletviewer -J-cp -J$CLASSPATH html_file. The problem is that I still get some errors java.io.IOException: File Not Found

Using awt/Swing methods without having to install X on linux server

Hi,
I've written a servlet that generates PNG images and send them to your browser. However, I get the following exception:
Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.
So I set the variable... but it still doesn't work, because I have no X server on my server, and I wasn't planning on installing a huge system hogging X server...
Any ideas?
Regards
Paul Hamer

AFAIK Headless AWT (AWT that doesn't need X) is one of the enhancements of Java 1.4. You need to set java.awt.headless=true on the command line of though (-Djava.awt.headless=true).
If you're not using 1.4 you'll need som awt replacement, one of the first I found with google was http://www.logicstyle.com/projects/wct/docs/userguide.html.
Another alternatve could be to run a fake display. On one of my linux boxes I kickstart /usr/bin/X11/Xvfb :1 -screen 0 1x1x24 -fn fixed -fc fixed -fp "/usr/lib/X11/fonts/misc:/usr/lib/X11/fonts/100dpi" &in my tomcat startup script. It creates a rather light weight virtual framebuffer with one pixel and satisfy my need to use awt to generate images.

Oracle 11g R2 install problem on Windows Server 2008 R2 SP1

Hi all,
Trying to install the Oracle 11g R2 database onto Windows Server 2008 R2 SP1.
I get as far as running the setup and a black window flashes up on the screen and disappears.
The log files only show the following:
Using paramFile: C:\Temp\database\install\oraparam.ini
Checking monitor: must be configured to display at least 256 colors. Actual 65536 Passed
The number of files bootstrapped for the jre is 0.
The number of files bootstrapped for the oui is 0.
I've tried running setup -debug from the command line but no further information is logged.
Any help in troubleshooting further is appreciated.

That is the complete log file. No error messages or further information is given.
I'm not sure how to check:
Statement of Direction: Oracle Database 11g Release 2 – Microsoft Windows 7 and Windows Server 2008 R2 [ID 867040.1]
I have checked on:
http://docs.oracle.com/cd/E11882_01/install.112/e24283/toc.htm
The server meets all the hardware requirements. The default file share is accessible and it is running a supported browser. The installer is being run with Admin rights. I'm not sure what else I need to check.

CF8 Install Problems on a Windows Dedicated VPS

Hello,
I have a dedicated VPS running Windows Server 2003 that I am
using to run CF8 on. However, I can't access the CF administrators
page. When you click on Administrator under the Adobe folder in the
start menu, the browser opens and acts as though it is bringing the
page up and then it goes to a download window like you are
downloading a program. Finally, the browser window returns the
message "Service Unavailable". I have tried to get the company who
I lease my VPS server from to help me, but they said this is a CF8
issue and they can't help me. The best they could do is tell me to
try accessing coldfusion through my VPS IP address with :8500 in
front of it. That still does nothing. Under Windows services, I
verified that the CF8 application server is running. I just don't
know what to do now. I would appreciate any help with this
matter.

If it is 64-bit Windows, CF is not supported on 64-bit yet.

Oracle install problem in linux

hi,
cannot execute the Export command before running the command ./RUNINSTALL.SH
Error is
OraSID#export DISPLAY=ipaddress:0.0
cannot find the command but i can find the export command in sbin and also i checked echo$DISLPAY and got output as :0.0 and also i can export in root user.

So if you get a value, don't set DISPLAY manually, it's only necessary if you display
- on a different host
- on the same host using a different user than the one you're logged in
RUNINSTALLER will run for some time before it fires up a GUI so be patient

Is vsftpd included in the Oracle Enterprise Linux Server Release 5.3?

Hi there,
I have just installed Oracle Enterprise Linux server release 5.3 (Tikanga). I was trying to setup the "vsftpd" service but was unable to find it. Do you know if vsftpd is distributed along with 5.3 or do I need to install it seperately? Although there is "gssftp" and I configured the same.
In case anyone knows please let me know.
Thanks.

Hi all,
I need this vsftpd thing also. Someone told me that it works as a file server right? We need to have sa centralized repository of all our Oracle Apps Documentations (BR100, MD50, Oracle Tutor, Test Scripts, TA100, etc)
How do you configured this thing as "centralized" repository?
Thanks a lot,

As we can see all the errors contained “echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.” and “blocked for more than 120 seconds” somewhere.
Explanation
By default Linux uses up to 40% of the available memory for file system caching. After this mark has been reached the file system flushes all outstanding data to disk causing all following IOs going synchronous. For flushing out this data to disk this there is a time limit of 120 seconds by default. In the case here the IO subsystem is not fast enough to flush the data within 120 seconds. As IO subsystem responds slowly and more requests are served, System Memory gets filled up resulting in the above error.
Solution
Increasing the vm.dirty_background_ratio by 5% and vm.dirty_ratio to 10, would give some buffer for the server.
Change vm.dirty_ratio and vm.dirty_backgroud_ratio
[root@localhost mercury]# sysctl -w vm.dirty_ratio=10
vm.dirty_ratio=10
[root@localhost mercury]# sysctl -w vm.dirty_background_ratio=5
vm.dirty_background_ratio=5
Commit Change by running the below command:
[root@localhost mercury]# sysctl -p
The above command should fix the kernel panic errors. However, a reboot would reset these changes.
So, we could monitor the server for a week or so and after confirming there are no more errors in the messages log, we could make this change permanent by doing the following:
[root@localhost mercury]# vi /etc/sysctl.conf
ADD 2 lines at the bottom
vm.dirty_background_ratio = 5
vm.dirty_ratio = 10
Save and exit by hitting the escape key + wq!
[root@localhost mercury]# reboot
More Explanation:
vm.dirty_background_ratio is the percentage of system memory that can be filled with “dirty” pages — memory pages that still need to be written to disk — before the pdflush/flush/kdmflush background processes kick in to write it to disk. My example is 5%, so if my virtual server has 32 GB of memory that’s 1.6 GB of data that can be sitting in RAM before something is done.
vm.dirty_ratio is the absolute maximum amount of system memory that can be filled with dirty pages before everything must get committed to disk. When the system gets to this point all new I/O blocks until dirty pages have been written to disk. This is often the source of long I/O pauses, but is a safeguard against too much data being cached unsafely in memory.

Hi,
Please apply the following correction manually.
1. Go to transaction ST03N
2. Change user from 'Administrator' to 'Expert Mode'.
3. Go to Collector and performance analysis -> Performance database
   -> Monitoring database -> Contents
4. Search where further info contains the string "h/2"
like the following monikeys:
- 'days h/2'
- 'weeks h/2'
- 'months h/2'
5. Double click on each, so that they become red and show ** delete
6. Finally SAVE
This will remove the corresponding database related history up to the deletion date. It will accumulate anew afterwards.
How can I identify the monikey that has to be deleted?
When you load the text of the dump and then jump off to the break point of the debugger you may find the error break point look like:
"IMPORT HIST2 FROM DATABASE MONI(DB) ID MONIKEY".
To find the right monikey entry causing the dump you can search for the word 'MONIKEY' within the text of the dump. This can be 'days h/3' or
'tabgrowth 2'...
You can then go back to the procedure above and search where further info contains the monikey that you found in the text of the dump.
