OCILogon returns success when TimesTen server is down which causes app core

In our failover testing, when the primary TimesTen server was brought down, the OCILogon call returned OCI_SUCCESS with a service handler. However the OCIServerVersion call which immediately follows the OCILogon call caused the application to core with signal 11.
Below is the stack trace in the core:

Does anyone know why OCILogon returns success when the server is down? And how can I tell if the server is down?
Thanks!
Cathy

Hi Cathy,
I'm not in a position to check this out right now but it certainly looks like a bug. Are you able to log an SR on this so we can get it into the system?
Thanks,
Chris

How to show an error Page in Weblogic when the server is down

Hi ,
I heard that every container has the facility to show an error page when the server is down and (when the request has arrived at that time ).
Please tell me how to configure this in BEA weblogic ??
Thanks .

Hi,
From my understanding weblogic dose not provide the thing which you are asking for, reason is given below.
- An application is deployed only on managed server one (MS-1)
- Now if the request comes to the server (MS-1) when it was running and then for some reason MS-1 goes down then weblogic server would be able to send any response back to the client as its down.
- Hence nothing can be done as the request object is been lost when the server goes down or even cant redirect to an error page as for doing that too the server has to be up and running.
However there are other way round which can help you overcome this issue as shown below
- Use Clusters with few managed servers in it which gives you high availability and load-balancing.
- Use any web servers like Apache in front of weblogic servers.
Using the above things you can also use customized HTTP Error Responses with error-page element in web.xml and create your own error pages which can be re-directed for the web server side also. For more information go through the below links

thanks thomas for your reply
but i think , we need to find out the point where it actually gets environment settings
there must be 2 things done before creation is done.
1]
Actual Construction of the Tree
2]
then getting look and feel of the underlaying OS
if we can find out step between 1 and 2 , we will get the problem ...
what say ??
dont think i am giving any suggestions to you . this is just what i think.
Please let me know if any of ur friends are facing the same problem.

Customise error page when content server is down

Hi all,
The following message is received when the content server is down:
Web Server Error Error attempting to perform request. (Unable to connect to address.) To administrate this server use this link.
I have seen a few variations fo this mesage on different conditions.
The question is: how can we customise this page?
Many thanks

hi all,
try this
You can set up the maintenance page when at the Web server level when the application is down in the App layer. Here is the reference for Oracle HTTP server, same you can do it for any other web server too..!!
You can achieve this by configuring an error page at the WebServer (part of web-tier).
For example, in the case of a Oracle HTTP Server (OHS), you could do the following:
1. Place your maintenance page at <ORACLE_INSTANCE>/config/OHS/<component_name>/htdocs.
For Example, <ORACLE_INSTANCE>/config/OHS/<component_name>/htdocs/errorPage500.html
2. Open the OHS httpd.conf located at <ORACLE_INSTANCE>/config/OHS/<component_name> in an editor and search for the string ‘ErrorDocument 403′ which can be seen as commented text. Next to the commented text line, add the below lines for configuring the Error
Pages (500 —> backend server unavailable, 403 —> forbidden request, 404 –> Resource Not available). For the below example, we had 3 html pages errorPage500.html, errorPage403.html and errorPage404.html are deployed in OHS htdocs.
ErrorDocument 500 /errorPage500.html
ErrorDocument 403 /errorPage403.html
ErrorDocument 404 /errorPage404.html
3. Save the changes to the httpd.conf file.
4. Restart OHS server

Controlling Broadcasts Attempts when PreCalc Server is down

In BI 7.X, is there a way to control the number of attempt that the BIBCAST jobs make when Precalculation Server is down. We would prefer that it failed after a reasonable number of attempts instead of just trying over again every 30 seconds.
Any ideas?
Mitchell

Dan,
Try to append the LOCAL key word to your authentication-server-group statement in your tunnel group or group policy.

Shouldn't ACE 4710 ignore cookie stickiness when the server is down?

Hello,
I have implemented sticky load balancing with cookies. The problem is that if one of my two servers in the server farm is down (and even if the ace recognizes it as down via a probe) it keeps sending the requests to the server that is down, obviously because it has set a cookie for this server,
Shouldn't the ACE ignore the cookie when the server is down?
Is there a command to ignore cookie stickiness if the server is down? Is there another workaround?
an example of my config is
serverfarm host SF_Ebanking
rserver RS_IAS_1 XXXX
    conn-limit max 4000000 min 4000000
    probe http_probe_ebanking
    inservice
rserver RS_IAS_2 XXXX
    conn-limit max 4000000 min 4000000
    probe http_probe_ebanking
    inservice
sticky http-cookie ACE_COOKIE ebanking_sticky
cookie insert
replicate sticky
serverfarm SF_Ebanking
16 static cookie-value "server01" rserver RS_IAS_1
24 static cookie-value "server02" rserver RS_IAS_2
thanks,
george

This is not as obvious as you seem to believe.
ACE will not select a server that is down !!!! Even if the cookie points to that server.
What might be happening is that the connection from the browser to the ACE has not been killed, so when client sends a new request it reuses the existing connection and ACE does allow an existing connection to be maintain with a dead server by default.
Try the command 'failaction purge' under the serverfarm.
This should kill the active connections with the dead server and allow a new connection to be open with the other server even if the cookie points to the dead one.
Regards,
Gilles.

Try this:
Go to System Preferences - Bluetooth. Delete the keyboard from the list of devices by pressing the "-" button. Take the batteries out of the keyboard and reinsert them. In Bluetooth Preferences press the '+" button to add the new device. If the keyboard begins to pair, click the word "pair" and type in the passcode. Press return. The keyboard is now paired.
If the mouse is not pairing, try this: shut down the computer completely, unplug any USB mice, then turn off the power to the bluetooth mouse. ONce the computer starts up again, wait for the pop-up looking for a mouse. Turn on the power to the bluetooth mouse. It should work normally now.

Urgent - Handle error when mail server is down

I think OP's problem doesn't related with FORMS. He should CATCH that error code and return normal readable error to user
Moreover, I advice to OP to read briefly documentation related with [UTL_SMTP |http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/u_smtp.htm#CHDCFFDI] package
And also to take a look at default [Exceptions |http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/u_smtp.htm#i1006659] which can be raised when using UTL_SMTP package

I believe that the key to understanding your problem is to recognize the subtle difference between authentication and authorization. The authentication process appears that it does succeed but the authorization process has failed according to your error message:
% Authorization failed.
I see that most of your authorization commands include the parameter if-authenticated. But this command does not:
aaa authorization config-commands
I would suggest that you add the if-authenticated parameter to this command and see if it does not fix your problem.

Hi Krishan,
If you want to check if local cache service is running, you can do something like this:
NamedCache cache = CacheFactory.getCache(sCacheName);
boolean isRunning = cache.getCacheService().isRunning();If you want to check if any storage enabled nodes (cache servers) are available in the cluster:
NamedCache cache = CacheFactory.getCache(sCacheName);
DistributedCacheService service = (DistributedCacheService) cache.getCacheService();
Set storageEnabledMembers = service.getStorageEnabledMembers();
if(storageEnabledMembers.isEmpty())
    // no cache servers available ...
    }Regards,
Dimitri

FTP Adapter File Polling does not raise error when FTP server is down

Hi All,
Thanks in advance.
I am polling for new files in a FTP Server. However, if the server is down there is no way for me to catch the fault to notify someone. I am using fault-policies but that never gets triggered when polling an unavailable FTP Server.
One option is to have a completely separate scheduled process (SOA or not) that tries to connect to the servers but I am trying not to go that route just to keep things manageable and within the realm of the process.
I am sure that I am not the only one polling for new files in a FTP Server, so I thought to pick your brain to tackle this scenario.
Thanks for taking the time to read this.

I was contacted by our DBA team for an exception received while writing a file to a FTP location.
Then i looked at the exception message and asked them to check the whether they are able to contact the ftp server using command prompt then they said the user password got expired.
They reset the password and its working now.
Am i missing something here :(
Exception:
WSIF JCA Execute of operation 'Put' failed due to: Error sending file to FTP Server.
Unable to send file to server.
; nested exception is:
ORABPEL-11429
Error sending file to FTP Server.
Unable to send file to server.
Please ensure 1. Specified remote output Dir has write permission 2. Output filename has not exceeded the max chararters allowed by the OS and 3. Remote File System has enough space.
Thanks,
Vijay

Redirect to a custom error page when Forms Server shuts down

Hi,
I want the forms application to redirect to a custom error page whenever Forms Server goes down. (like network issues, unscheduled shutdown...) Whenever this happens, the user gets a pop up with FRM messages and user has to acknowledge the pop up. Since the application is used in the shop floor, there will not be any user always in front of the screen and will be a very big issue as there are at least 70-80 PC's on the floor which will be attended fewer times(only when there is issue with the machine) other wise the application displays important events of the machine,etc.,
I am trying to develop a simple HTML error page(may be with applet) which will keep querying the forms server and once the forms server is up and running, the error page will revert back to the application which the user was working earlier to shutdown. Other option is the redirect to main menu of the application (this may be a PSP or a JSP or a Oracle Forms Menu ).
Is there any event in forms to capture the loss of connection to forms server ??
BTW, I am using Oracle Application Server 10g Forms and Reports on Windows 2000 Server...
Any ideas...
Thanks in advance
Purush

I don't think it will be easily possible in Forms for a couple of reasons.
1. In Forms you do not have query rights, and as soon as you want to edit data, you have to log in. In Forms you log in once, and this sets your rights for the whole session. You will have to do some programming in Forms to achieve what you want. E.g. as soon as you hit the Save button you are asked for a username and password.
2. A refresh cannot be done in Forms. Remember that Forms is a Java applet. The URL in the browser is just pointing to the startup page only. If you refresh your screen, you are taken back to the login screen of Forms again.
Well, there will probably be ways around these problems. I'm thinking in the line of calling every form in a separate URL instead of starting a Forms application where one form is called from another form. The default 'query only' form can be called from a startup html page. This page can be refreshed. As soon as the user wants to update data, he clicks on a link or button and is taken to a login form.
If the refresh is unsuccessful you are taken to a custom error page, like in your ASP application.
A problem with an automatich refresh may be hanging sessions. Forms server does not always kill sessions.
And also, how would you avoid a refresh if a user is currently using the form?

EMail Alter when Essbase Server is down....

Hi,
I am on Essbase 7 & Windows server. Essbase is running as service in the server.
Current Process: Whenever the essbase server is down or not responding, we don't have a clear cut mechanism to identify that the server is down, until unless some user notify us the issues and we later we correct the issue
Needed Process: is it possible to send an alert to the admin when ever the essbase server is down or some kind of alert from essbase.
Any help is much appreciated.
Thanks,
Sunil

Hi Sunil,
You can send mail in following ways: -
1. Use custom java functiion to email from your calc script. You can find complete information about Java API from following link: - http://download.oracle.com/docs/cd/E10530_01/doc/epm.931/html_esb_api/api_j/japistart.htm. Also please refer chapter 30 Developing Custom-Defined Calculation Functions of Essbase Administration Guide.
2. You BLAT or another email program to send an email from your batch file e.g.
sendmail -b E:\Logs\Dataload.log -s "Subject of the mail (data load status)." -f Sendersemail -r Recievers email -r Receiver’s email -X HQSMTP.yourcompany.net
Hope it will help you.

ACE slowness issue when one server goes down

Hi,
We are having two application servers.Both are load balanced using ACE.
When we bring down one server, we find that when we upload some files into the second application server, its too slow.
But when primary server comes up again the performance increases.This issue happens only when we bring the primary server down.
We are using cookie based stickiness.Any ideas where we can look into.
Rgds.,
Sachin

Depending on the load-balancing algorithm or predictor that you configure, the ACE performs a series of checks and calculations to determine which server can best service each client request. The ACE bases server selection on several factors including the source or destination address, cookies, URLs, HTTP headers, or the server with the fewest connections with respect to load.
