does anyone know the effects and solutions mentioned below?
IBM has no solution since any weeks.
In our Cognos environment v11.1.7 there are following servers in the same subnet:
Server 1:
Contentmanager + AppTier installed in one directory.
2. AppTier installed in a separate directory
Server 2:
Contentmanager (as standby) + AppTier installed in one directory
Server 3: only gateway server installed
The 2nd AppTier server on Server 1 is shown as "unavailable" in the Cognos system.
The AppTier server on server 2 is displayed as "not available" in the Cognos system.
AppTier server on server 1 is displayed as "available" in the Cognos system.
If you test all dispatchers (AppTier servers), they are all available. You can also work with them.
Only the availability display is not correct.
Maybe there is a reason why I can't get data from the 2nd AppTier with Jconsole / JMX with all above mentioned variants.
From the first AppTier I get data.
Local firewalls are configured that all ports for Cognos are open.
I have the problems also with switched off local firewalls.

For my upcoming bachelor's thesis I want to develop a tool that collects system and application data from Apache Flink and sends this data in some kind of "events" to another system. This tool will be installed on Flink job- and taskmanager nodes. Beside data from linux system utilities like dstat I would like to collect JMX data.
My problem is, that I couldn't figure out how to connect via remote JMX connection by using a port to Flinks jobmanager. Although the collector will be on the same machine, I really try to avoid using a --javaagent to access JMX data of Flink's JVM.
Another problem is, I have a local docker setup based on https://github.com/apache/flink/tree/master/flink-contrib/docker-flink and updated to flink-1.0.2, that I cannot connect via jconsole because I don't know how to "open" a JMX remote port for the job- and taskmanager.
Is there any way to achieve this?
Thanks in advance, any ideas very appreciated.
Solved!
I needed to add env.java.opts: -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
in flink-conf.yaml.
No it's possible to connect the jobmanager via jconsole.
We are using OPSHub free version for migrating On-Premises TFS 2013 to cloud (VSO 2015).
During Opshub installation we got an error message "Unable to connect to remote server, check the internet connectivity or Proxy settings and try again".
We found the following link http://www.opshub.com/main/ovsomu-proxy regarding this issue and we contacted our network team to get the proxy server details (to put them in the environment variable _JAVA_OPTIONS), but they would like to know how Opshub connects to internet and all the inbound and outbound connections from Opshub, which port it uses and if the data is encrypted during installation and migration etc. Can Opshub support help us out in providing this information?
OpsHub use the standard VSTS ports of https which is encrypted with SSL. There are no inbound coms.
I would however not recommend the OpsHub tool as you will quickly run into an upsell from them. If it works for you then awesome, but if they as you for money then switch to the TFS Integration Tools that are free and supported by the TFS product team.
Yes, OVSMU requires to connect to the OpsHub website during installation for Verification Code generation process. (Thereafter, it does not connect to our website)
Once, the utility has been installed, it occupies two ports 8989 and 9090 as long as the tool is running. For communication with end points, it uses the default TFS and VSTS ports.
I know that the recommended approach is to monitor WebLogic 11g via HP SiteScope. However, my client hasn't purchased a HP SiteScope license.
I was looking at http://easyloadrunner.blogspot.com/2013/07/how-to-set-up-weblogic-monitor.html
and it appears that LoadRunner has a native WebLogic JMX monitor.
Does anybody know if it supports WebLogic 11g?
If not, any suggestions short of HP SiteScope?
--Thank you,

If your client has LoadRunner past version 8 then a base 500 point SiteScope instance comes as a part of the LoadRunner license. This is part of the monitoring foundation of the LoadRunner
Chicago Boss is a great Erlang Framework. It ships with many dependecies including mochiweb, yaws, and misultin. After installation, Chicago Boss runs a development server very well.I need to know which of the web servers it ships with, does it use by default ? and how can i change from one web server to another without compromising my Chicago Boss project ?
From CB Wiki:
All configuration takes place in boss.config in your project directory....
Webserver
port - The port to run the server on. Defaults to 8001.
server - The HTTP server to use. Valid values are:
mochiweb - The Mochiweb Web Server
misultin - The Misultin Web Server
So check in boss.config for which web server you use.
Hope this helps!
