The Performance Center Host could not connect to the ALM Platform using REST.

Jump to solution

Hi All,

 

ALM 11.5 + SQL 2008 R2 configuration has been installed on virtual machine with Win2008 R2 operating system, hosted on VMware Linux box. PC 11.5 was deployed on the same virtual machine.  System deployment passed successfully in general,  but with a several warnings in configuration log (attached). 

Load controller and load generator (virtual servers with Win Server 2003 sp2 os) were installed and successfully added to ALM Lab management (firewall is turned off on all servers).

 

Problem occurring when I’m trying to start a performance test. All attempts failed with 'The server is not responding, check configuration, check if request is made to correct server, check if the server is up. Unable to connect to the remote server" reason. 

 

During System Health check the following error-messages were also observed:

"The Performance Center Host could not connect to the ALM Platform using REST. Error message: The server is not responding, check configuration, check if request is made to correct server, check if the server is up. Unable to connect to the remote server"

 

Please give me the way to find.

 

Thank you in advance!

There are several questions about your environment.  

 

1) Is your ALM server Linux? 

 

2) PC Server can only be installed on Windows.  Are you trying to install PCS on a Windows Simulation running in Linux? If so, this would not be supported.


3) PC Host software can only be installed on Windows. Stand Alone Load Generator can be installed on supported Linux OS's. 

 

4) When you add the Load Generator to  Lab Management are you selecting Stand Alone Load Generator as the type?

Have you verified that your Windows and Linux OS versions are fully supported?

 

From your description it seems that everything in Lab Management is running fine. Do the check host, check server and System Health checks all report no errors?  If so you can try the following:

 

a) RDP to the PCS server.  Login as IUSR_METRO (or the appropriate user if you have changed this using the identitychangeutility.

b) Open a IE browser and connect to your ALM server (http://almserver:8080/qcbin) and click on Performance Center (Application Lifecycle Management if appropriate for your environment) and download all of the client components.  You can verify that everything is OK by logging in.  If you can't download the components while logged in as IUSR_METRO you need to resolve this first.  Often this will be security related issues with the IE configuration.


c) Repeat step B but connecting to Site Administration

 

d) Repeat A - C for each full host install

 

Once this is complete, try running your test again.

 

If you have errors in either Check Host, Check Server or System Health please resolve those errors before attempting to run any tests.

 

Other standard checks you can do:

  • Ensure DEP is disabled on all PCS and Host systems
  • Ensure the Enhanced IE Security is disabled on all PC components
  • Ensure and UAC is disabled while logging in as IUSR_METRO
  • Ensure that there are no Firewalls between ALM, PCS, and and Host systems.  Built in Firewall must be disabled as well as any external firewalls on your network
  • Ensure that the environment variable TMP and TEMP are changed to something like C:\PCTEMP while logged in as IUSR_METRO (Change C to another drive if space on C drive is limited)
  • The ALM, PCS, and Host systems should all be in the same room, or at the very least the same building.  You can put stand alone load generators anywhere in the world but these core systems need to be all co-located on the LAN and not the WAN

If all of this still doesn't resolve the problems you are having I would strongly suggest that you open a technical case with HP Support to work with an engineer directly to resolve the problems that you are having.

It is recommended not to install ALM and PC server in same machine.

In Lab management,

Try to see the status of your PC server.

You can also check there if there are errors encountered.

You can try to delete your current connection (ALM-PC) and create a new one.

In adding a PC server, do not use "localhost" for the address, it's better to use the IP address.

Many thanks for your help!

 

The issue was fixed after disabling of the Enhanced IE Security, DEP and UAC  on all system hosts.

 

Thank you!

Is there any issue having a HOST installed as a Controller in a separate domain than the ALM & PC server? 

 

All appropriate firewalls are opened and have performed every one of the validation steps you suggested here with success. HOST can connect to ALM Platform via OTA API but not REST. After addind HOST in Lab Management data for processes, services, installed software and PC components are all correctly displayed. The only failure is at the connection from the HOST to the ALM Platform via REST.

 

Thanks,

We added the ALM Servers host name and IP to the Windows Server Hosts file and this fixed our issue.

Re: The Performance Center Host could not connect to the ALM Platform using REST.

Hi everybody!

I have an issue like this, but "...Error message: Failed to fill property State with value "Working"" . My PC Server was added in the Lab management and works fine.

The problem is I can't log in and pass through the authentication in My Performance Center. So I have a suggestion the reason is this message.

Connection between PC and ALM exists. Why I can't see any domain/project or what component can't start after I push "Authenticate" button?

I have default Lab project in my DB. ALM users were linked to it.

PC Host log file below.

Thank you for your help.

The reason was - it must be enabled "ALM Lab Extension for functional and performance testing" (Site Administration - {Project properties} - Project Extensions
