 Hi Team,


Scenario is that we have 

RTC Server 6.0.6 on installed on Linux and we have zD&T v10 where have Agent 6.0.1. 

Question is if these two are compatible. Can I run Builds on zD&T with Agent 6.0.1 and Server 6.0.6?

 All,


The issue is resolved now 

1) First issue was that zOS was not connecting to RTC server, the ports were opened (9443)
2) Second issue was that zOS was not able to resolve the DNS name of RTC Server , we used IP Address and it worked like https://10.111.429.12:9443/scm instead of https://rtcserver:9443/scm
3) For DNS name to work we need to add the entry of DNS name and IP Address in IPNODES member of TCPPARMS on zOS 

Hope this answer helps others who face similar issue

You must never, ever, ever use a IP address with any production Jazz deployment. You must use a fully qualified domain name for that and it must be used from the beginning. The URI e.g. https://elm.example.com/ is called a public URI root and plays a central role in the whole system Changing it requires a server rename process.   Otherwise you might corrupt your deployment. Fix you zOS system.

 Ralph, we have made update on zOS system to use URI only. Now we are able to access RTC using URI not IP.

Great to hear you fixed it.

In general EWM/RTC supports N-1 compatibility.See link next line.

On the ELM download pages in getting started is a link to the System Requirements, which also contain related information.

In general I would your setup expect to work from the Jazz perspective.

 Thanks Ralph for the answer. I tested the build and it fails with below . Its says version compatability issue. Is it because RTC server is of version 6.0.6 and RTC Agent on zOS is 6.0.1?

The error message does not seem to necessarily say that there is a version issue. The error message seems to say it can not log into the host or find the host https://rtcserver.lnx:9443/ccm/.%C2%A0 It explicitly says: Verify that the repository address and credentials to log in are correct. Please note that in the post here there is additional stuff behind the ccm/ . Not sure that contributes. This can be just a connectivity issue. The version check page is only visible, because that is the first page a client is redirected. My 2 cents.

 Thanks Ralph for the response. Yes I am also working with my admin team to check on the connectivity issues.


But want to understand the flow when perform build, does :

1) RTC Client first connect to RTC Server and then to RTC agent(zOS) ?
2) Does RTC Agent(zOS) should be able to connect to RTC Server? When I checked this connectivity is not there?
3) Does RTC Server need to talk to RTC agent ? We have opened port 5555 for RTC server to talk to RTC Agent on zOS

Any other thing or flow I am missing ?

 I don't know anything about the zOs side of RTC.

Hi...we have RPT 8.5.0.2 installed in our environment, with test agent 8.5.0.2 deployed on several servers.  I'm considering an upgrade of the RPT workbench to 8.5.1.  Will the 8.5.0.2 agents work with RPT 8.5.1? I'm trying to avoid coordinating multiple simultaneous upgrades, especially since upgrading the agents requires service requests with another team.
