Howto notify admins when server goes down

hi all
I want to learn that how do you monitor the BPEL engines? Can you send snmp traps or do you use any other mechanisms? and how?
Maybe i will only send alert when engine crashes or in similar cases.
Replies will be very useful to solve this issue .
Thanks

additional comment: We don't use WSM(webservices manager).

JMS Exception when server goes down (Urgent) ?

Hi All,
I have three topics in the JMS Server which is on the top of Web logic server 8.1.
On the client side I have Swing thick cleint.For each topic I have a listener.
When the web logic server goes down ( I shut down manually ) Only one listener is recieving the Exception and the Swing client reacts accordingly.
After this ,
Client continousoly checks whether the server is up or not. Once the server is up again the Exception is thrown that server is down ( I guess now the second listener is recieving the message).
After some time again the third listener recives the message.....
and the client reacts on that exception 3 times.
How can I get rid of this ?
thanks in advance.

Hi,
this is probably a very good question to ask support. 'Logical' deployment sequence
was added to the WebLogic only recently (6.1sp?) ('logical' means that first datasources
are deployed, then EJB's and then web-apps, deployment-order parameter was added etc).
So, for applications where shutdown sequence is important there must be a document which
describes how server shutdown works.
On the other hand, this may not be as important as deployment sequence, because running
instance can crash at any time and it should not affect anything.

Hi,
Most of my ejbs use connection from the connection pool. At the weblogic server shut
down time (heavy load), I can see the jsps call the ejb, sometime jsp can't find
the bean because it's removed from jndi. sometime jsp found the bean but when the
bean try to talk to database, ejb can't use the connection because the datasource
is removed from jndi. Also my shutdown class waits for the threads finish up, and
the threads calls the ejb and do the db operation, and the conn is cut when the db
operation is half way. So, the order of events when server shut down is important
to me. I am wondering how other people deal with it. Thanks --

How can a JMS Listener Notified get when a Topic Server Goes Down?

I'm in the process of looking into pub/sub model for a centeralized data source where vertical applications subscribe to a topic to get updates on person demographic information.
          I was playing with the JMS topic examples and noticed that when I have a Durable Subscriber listener (java main) and the topic Server goes down. It never gets notified. When I restart the Topic server and send msgs to the topic, the Durable Listener doesn't get them.
          Once I restart the Durable Listener (java main), it receives all the messages that were pending.
          I implemented the ExceptionListener and it never gets a shutdown msg either. I shutdown the Topic server via Ctrl-C, Graceful Shutdown and Forced Shutdown.
          Is there a way for the client listener to determine when the Topic Server went down, came backup, and restore the connection to it automatically? Or do we have to implement some type of ping mechanism on the client listener and re-create the connection ourselves?
          Thanks. Later...

Hi Wayne,
          I think the exception listener should have fired. Some comments/questions:
          - Does your app call "connection.setExceptionListener" in addition to implementing ExceptionListener?
          - Which version and maintenance/service pack are you using?
          - Is the client using the wl* "thin" client jars or the "thick" client jar?
          - Version 9.2 provides an automatic reconnection capability for consumers. This behavior isn't enabled by default due to natural side effects that some apps might not be prepared to handle (needles to say, I recommend reading the doc thoroughly).

Hi,
You could try increasing the java heap size, though sometimes an issue can occur if you are trying to delete a member when a workflow process has started, do you have one running?

What happens to client session when host goes down?

I have a windows 2012 R2 RDP environment. 1 Broker and 3 Session Host Servers.
My question is as follows:
User connects via broker to one of the Host servers. Host server goes down, while user is still connected. Session is written in Broker database. User wants to connect again, but broker sends him on to the server which is down and so he cannot connect.
Other situation is similar, User connects to host, administrator drains host, stopping new connections. User disconnects session, session is still in Broker, when user tries to reconnect is sent to drained server but cannot login, as he is considered new
connection.
What am I missing?
Aaron

Hi Aaron,
Thank you for posting in Windows Server Forum.
We need to configure RDSH in a load balance farm where it can be managed by RD Connection Broker. For that we need to use DNS RR where need to make entry for all RDSH server which will be handled by RDCB Server or we can use any load balancing method to load
balance the different RDSH server and thus that connection will allow the disconnected session for reconnection and can identify the connection.
The RD Connection Broker for RDS serves the following main purposes:
• Determining the best RD Session Host server to connect to - this is based on the amount of current sessions per RD Session Host Server as a form of load balancing.
• Reconnecting a user to an existing session, in case there is one - this is called reconnecting to disconnected sessions.
• Being a resource for RD Web Access to deliver information about what Remote Apps are available on RD Session Host Servers that are a member of the broker.
More information.

Server Goes Down Alert

Hello,
I am running SCOM 2012 R2 and I am trying to setup an alert to let me know when a server goes down. I tried creating a rule that monitored the Management Server's "Operations Manager" Event Log for ID 20022. I also configured
the rule that parameter #2 must have my servers name. I also tried EventDescription conatains my servers name. None of them worked. But I looked in the Event Log of my Management Server and as I looked at all of the 20022 entries, I noticed
the computer I was on was listed as not heartbeating. Two of my other servers that are currently on were listed as not heartbeating. So obviously monitoring this 20022 entry is not reliable. I do not want to setup a monitor for something
like Ping Status. I want to try to avoid using monitors because they could be taxing on the servers, my management server, and my network.

Hi
yes event id 20022 is not reliable and never go for windows event id monitor for server shutdown or unavailability on agent , as scom health service will be stopped or connection closed with MS at the time of shutdown on agent.
you need to go for ICMP port monitoring for server availability, as port monitoring run from remote server(watcher node) and can capture server unavailability and ping test.

Load balancing - what happens if a server goes down?

Hi, Just an academic question.
Assume I have 2 DA servers behind a BIG-IP load balancer, named DA1 and DA2.
If I enable Load Balancing (BIG-IP in my case), what happens to the clients already Connected to DA1 when IP-HTTPS is used?
For example:
Client1 is connected to BIG-IP, which in turn redirect this client to DA1-Server. Assume that DA1-server goes down, what happens with the client then? I assume the Client will be redirected to DA2-server by BIG-IP after some time, meaning it will have to establish
the connection from scratch. Is this correct and roughly how long does it take for the clients to connect to the DA2-Server?
Since IP-HTTPS is using it's own pool and IPv6 prefix per DA server, I assume this will happen? And the DA client1 will receive a new IPv6 address from DA2 ?
Thanks!

Hi,
It depends of the way your Big-IP is checking the servers in your pool.
The client will try to reconnect to the HTTPS interface and still be redirected to server1 until your Big-IP validate that the server1 is not responding and disable it.
And yes, you'll receive a new IPv6 address because each server in a DirectAccess NLB cluster has a specific IPv6 range for the clients.

Flash Media Server goes down mid-stream

So if my application is streaming a video and FMS goes down
during it... I need to be able to error handle this. I'm wondering
if FMS would return some sort of message or error upon going off
line or if there is any other manner in which I could handle this.
Ultimately I'd like to give the user a message informing them of
the problem... or possible just switch to a progressive version of
the same clip.
Any ideas?

Well... if the server goes down it can't very well respond to
it.
What you want to do is have your client side
netConnection.onStatus method repond to the change in the
connection and notify the user.

Functionalities Available if Server Goes Down?

Hello! As a structural question...... I have a web server that holds my web application (includes My Sites), and an application server with CA and all of the other services.
Suppose the web server goes down. Does that mean my users no longer have access to the site, their profile, and their document libraries?
Conversely, if the application server goes down, will my users still have access to the site, but none of the services will work? (IE. Will the site still communicate with the databases to pull documents information from their documents library; I just can't
use search, etc.)?
Thank you!

Suppose the web server goes down. Does that mean my users no longer have access to the site, their profile, and their document libraries?
Correct. If the server hosting the Microsoft SharePoint Foundation Web Application Service goes down then you will lose all access to the sites.
Conversely, if the application server goes down, will my users still have access to the site, but none of the services will work? (IE. Will the site still communicate with the databases to pull documents information from their documents library;
I just can't use search, etc.)?
Thank you!
Again correct.
Depending on what exactly you've put on the App tier and on the WFE tier you may still have working sites. If there's a component that is needed to render a page such as the MMS or Excel Services that runs on the App tier then that page will throw an error
but the general document library pages and so on will probably still work for the most part.

Why Portal server goes down?

Hi All,
We are currently running on EP7, SP9.
Suddenly one day our portal server went down.We checked the logs but could not find the correct information. Can any one of help me as why our server went down at that particular time.
Please reply as soon as possible.
Thanks in Advance.
Regards,
Ramalakshmi.S

Portal server goes down for several reasons:
1) Check the portal license. If the trial license expired, it goes down every 30 mins.
2) Check your J2EE settings. If the portal cannot handle the user requests, you should increase the MaxThreadCount and other parameters.
3) Check the trace files at D:\usr\sap\<SID>\JC01\j2ee\cluster\server0\log
Hope this helps.

Server Goes Down

Hi All,
I am using AS9i, Forms Server 6i, and Database 9i on a single Server Machine (Dell 2950).
I am facing a problem on my server,
Some time ifweb60 process capture the 100 % CPU. and did not release it.
and server goes down .
to recover it I have restarted the server, But its not a proper Solution.
I need help from U people to resolve the problem.
Regards,
Raza

You will need to go through your log files to find out what is happening, I guess.
Also you can use Process Lasso (http://www.bitsum.com/prolasso.shtml) to avoid your server becomes unresponsive if one process takes 100% cpu.

Auto start of db when it goes down

Is there any way using script to start database when it goes down due to some unexpected reason on windows platform?
Oracle 10g
Windows 2003 Server

Hi,
Create your own batch script that does the below things
1) Make a connection to Oracle to see if database is up.
2) If not then start the database.
I would be better checking why Oracle database is going down too frequent rather doing auto start.

Siebel 8.1.1.5 and BIP 10.1.3.4.1 Integration - Siebel server goes down

Hi Gurus,
I followed the steps as per the Siebel Reports Guide Rev. C and I can see the BIP Screens , views and the standard template. Also if I upload any custom template to in the siebel I can view those reports in BIP SiebelCRMReports folder.
But my issue is if I click any any screens in Siebel and then the list applet or form applet and then if I click the "Reports Button" in the top menu then the Siebel server goes down or sometimes the application hangs up. I don't know exactly the error is on Siebel side or BIP side and one thing I didn't check is the Integration Objects in Siebel tools for the standard report templates.
I'm on windows environment.
Any help would be very much appreciated.
Thanks

Hi Jing Jang
if you click the report menu button, I guess Siebel checks which reports are associated with this particular view. If the while OM crashes at this point, it looks as if some of the repository changes in 8.1.1.5 were not successfully applied. Did you import the provided .sif file which came with the 8115 BIP ACR?

L2TP script to initiate a router reload when tunnel goes down - working

Hi,
Just thought I would post a working EEM script on doing a router reload when the L2TP tunnel goes down....
I am using a 3825 router to initiate a site-to-site tunnel with a 3rd party vpn service - StrongVPN. On the odd occasion when the tunnel goes down, the l2tp tunnel state goes to "no session left" and the virtual-ppp1 interface - which is tied to the l2tp vpn - goes down. Unfortunately, because I have no control on the far end router, the only way to bring it back up is thru a router reload....
Here you go:
event manager applet L2TP-DOWN
event syslog pattern "%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-PPP1, changed state to down"
action 1.0 syslog msg "The L2TP VPN is down"
action 1.1 cli command "enable"
action 1.2 cli command "reload in 10" pattern "confirm"
action 1.3 cli command ""
action 1.4 syslog msg "EEM scheduled reload in 10 minutes"
event manager applet L2TP-UP
event syslog pattern "%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-PPP1, changed state to up"
action 1.0 syslog msg "The L2TP VPN is up"
action 1.1 cli command "enable"
action 1.2 cli command "reload cancel"
Jason

Hi Arie,
So, here is the script I am using....
When the L2TP tunnel goes to "no sessions left", the virtual-ppp1 interface goes down. That's the typical message I get when it goes down. So, when I reboot the router, the script shows the message that the virtual-ppp1 interface is up when the L2TP tunnel comes up. I checked the debugs and that is the behaviour when the tunnel goes up / down...
Here you go:
event manager applet L2TP-DOWN
event syslog pattern "%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-PPP1, changed state to down"
action 1.0 syslog msg "The L2TP VPN is down"
action 1.1 cli command "enable"
action 1.2 cli command "reload in 10" pattern "confirm"
action 1.3 cli command ""
action 1.4 syslog msg "EEM scheduled reload in 10 minutes"
event manager applet L2TP-UP
event syslog pattern "%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-PPP1, changed state to up"
action 1.0 syslog msg "The L2TP VPN is up"
action 1.1 cli command "enable"
action 1.2 cli command "reload cancel"
Thanks.

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.
