Problems when the server is down

When the server is restarted after a task is assigned, this task saves its state
(claimed). After that, when I try to mark that task as completed, the server says
that the conversation id is not found. Is that a Bug? or how can I fix that problem?
Thank you

The process doesn't finish because it's waiting for a task complete event.

i face this problem frequently. I believe the archival and Purging process
of the
WL integration archives and purges the Process Instance Info for those
instances
that are completed or Terminated. But i could see the tasks created by
these instances
left behind. If a user does any operation on these tasks result is the
"Conversion
Id not found exception". Iam not sure if this is a bug or is it by design.

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.

Gilles.

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

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

any help is appreciated
thank in advance

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.

SCOM 2012 Console not responding when the server to be connected is down.

SCOM 2012 Console hangs when the server to be connected is down or gone (e.g. lease replaced). How to change the 'connection server' to point to a valid server without re-installing SCOM Console? Thx

Is there a requirement to restart the JMS/Weblogc Server everytime when the DB goes down?

Question:
When the Database is shutdown gracefully everything was fine.
But when the Database is brought down with shutdown abort the MDB consumer will never consume messages from the topic again. And we need to restart the WebLogic Server in order to get the messages consumed again.
So is there a requirement to restart the JMS/Weblogc Server everytime when the DB goes down? If not, what type of failures will require the JMS/WLS restart?

On a DB failure, a WL JDBC store service will make a brief attempt to reconnect before shutting itself down along with any services that depend on the store.
It isn't necessary to restart the entire WebLogic Server JVM to bring the affected service(s) back if you can use the Automatic Service Migration feature. ASM can automatically restart a failed service on a different WL Server in the same cluster, and/or can try a restart-in-place for the service if the service's original host WL Server JVM is still running. The Automatic Service Migration (pdf) white-paper has a thorough discussion of this area.
In addition to ASM, there's also a "whole server migration" option that can automatically restart or migrate an entire WL server.

Contribute 3: Could not connect because the server is down or not acceptiong connections.

Hi,
I have two customers who use Contribute 3 and are currently
having the same problem:
When they want to Publish a page, they get the following
message: Contribute encountered a network or file system error.
Then they can click on "Connect" and get: Contribute could
not connect because the server is down or not accepting
connections.
They don't have an internet connection problem, there's no
firewall that blocks Contribute.
Regards,

I have spent many hours trying to get reconnected to my site.
My PC died in early January and I have not been able to get
reconnected since. I get the same error message. My Network
Aministrator has worked with me to see if there are any firewall or
antivirus issues blocking the connection. I administer the site so
have had to do elaborate work arounds to get users' pages
published. I am using WebDAV. My question: I would like to try
creating a new username and password (which is about the only thing
I have not tried yet.) If I do so, and get connected, I should be
ok with sending a new connection key to the users, is that
correct??

Since upgrading to Yosemite I am getting frequently "safari can't open the page (blank) because the server unexpectedly dropped the connection this sometimes occurs when the server is busy. wait and then try again"

Since upgrading to Yosemite on my iMac I am frequently getting "safari can't open the page (blank) because the server unexpectedly dropped the connection this sometimes occurs when the server is busy. wait and then try again". This is with both a WiFi and Ethernet connection. The server is working fine from other devices using WiFi onto it such as iPhones, iPads, MacBook (which is also on Yosemite) so don't believe its an issue with the server.
I am also noticing page load very slowly when this problem is not occurring.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

When I run SB1H the following message appears:
There is a problem with the server's security certificate. The security certificate is not from a trusted certifying authority. SAP Business One is unable to connect to the server.
Any idea what could be the solution?

Hi,
Please check SAP notes:

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,

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

CS5 - Contribute could not connect because the server is down

we have a client who has site hosted with us. They are using Contribute CS5 to connect to our web server and make changes to their site. They've been using Contribute for a month when all of a sudden they started receiving the error:
Contribute could not connect because the server is down or not accepting connections. Please contact your administrator.
Our server is up and running, their site is up, their ftp password is not locked and network said they can see can see end to end FTP transactions, logins and authentications. Communications between the application and the server is being allowed through all the various firewalls and devices along the way.
I've done some research but cannot find a definitive resolution. Any help with your product would be appreciated.

Can you please try clearing the Contribute preferences once?
In Windows -
Quit Contribute.
Go to C:\Documents and Settings\<username>\Local Settings\Application Data\Adobe\ and delete the Contribute CS5 folder. (In Windows Vista or Windows 7, go to C:\Users\<username>\AppData\Local\Adobe\ and delete the Contribute CS5 folder.)
Also, run reg delete "HKCU\Software\Adobe\Contribute 6" /f
In Mac -
Quit Contribute.
Go to Users/<username>/Library/Application Support/Adobe/ and delete Contribute CS5 folder.
Also, go to Users/<username>/Library/Preferences and delete Adobe Contribute 6 Preferences file.
Note: Doing this will remove all the existing connections in Contribute. It will be like a fresh installtion of Contribute.

Contribute could not connect because the server is down"

My client tries to connect to the website with Contribute and
gets the error "Contribute could not connect because the server is
down" however I connect with no problems, using Contribute or
Dreamweaver.
I sent him a new connection key but the same error.
Only problem I ever have is that sometimes I get a "can't
save files to shared something-or-other" on exit after
administrating, but I don't know if that's related or not - it
never seems to affect anything at my end.
Please help! Thanks

OK, problem solved here:
The access denied or file does not exist error was being
caused by the fact there was a 0KB index file somehow.
Once we got rid of that we still had the "Contribute could
not connect because the server is down or not accpeting
connections" error to get round.
I had previously asked my client to go in an change the FTP
settings in the Advanced screen to be Choose FTP server settings
manually and select Use Passive FTP to connect to the server and
make sure Use FTP Performance Optimization is not selected. I don't
think this was ever done (and if it had been it would have saved me
HOURS of time spent trying to diagnose this problem).
Today I ended up backing up every contribute related file and
folder on the server to my local machine then deleting them. After
having done that I asked my client to create a new connection using
the FTP details (not a connection key). That still didn't work so I
got them to (and this time they did it) change the advanced FTP
settings as above and BINGO! they can now publish.
I'm guessing that if I had sent a connec tion key with the
same settings specified in the Advanced FTP then it still would
have worked.
I hope this saves someone else some time. I am going to have
a few beers now to celebrate.
