[resolved] Connection to Generator failed (Command Line)

Anonymous — Sat, 16 Nov 2024 12:41:00 GMT

Hi,
i have following problem:
We have just installed TIS and want to start a second job from the TAC. But everytime we got an "Connection to Generator failed (Command Line)". I have checked every SVN connetion. Everything is "OK".
One strange thing is, that the first job is valid and is runing. But if we "generate" this job again we got the same error as the "new" second job.

Hi
Try to do:
1. Stop the commandline.
2. Delete the commandline-woskspace.
3. Restart commandline and generate the task again.
Best regards
Shong

I have the same problem. Should I delete every item in the commandline-worksapce (\\drw-sql01\c$\Program Files\Talend-4.2.3\cmdline\studio\commandline-workspace) folder or just the project folder ?.
Thanks,

Hi Ar7368
Delete the commandline-workspace directory.
Then it will be recreated when you start up TOS next time.
Regards,
Pedro

Hi Pedro,
The command line is still down. The client log in TAC says "Error at grid loading: Fail to connect to CommandLine: Unknown.hZ(Unknown source:0)". What does it mean?
Thanks,

Hi Ar7368
When you are using TAC->Job Conductor to deploy jobs on JobServer, the commandline needs to be started up(%TIS%\Commandline.bat or %TIS%\commandline-linux.sh).
Besides, you'd better check the parameters about commandline in TAC->Configuration.

Pedro

Hi Pedro,
I did restart after I restarted the services on the server where Talend resides. So now the primary commandline is working, but the secondary still errors. This is Ok for now as the jobs are running as scheduled. Any idea why commandline (secondary) still errors?
Thanks,

Hi
You mean the secondary parameters about commandline in TAC->Configuration still get errors?
It's OK. If you start up commandline using the secondary parameters, the primary one will get errors.
Hope I didn't misunderstand you.
Regards,
Pedro

Re: [resolved] Connection to Generator failed (Command Line)

ar7368 — Thu, 12 Apr 2012 14:29:31 GMT

yes the secondary commandline in tac-->configuration. So what you are saying is that only one commandline will be in use at anytime. Well that's fine as far as the jobs run as scheduled.
Thanks,

Have you tried to type "help" to get all commands of the commandline?
Or check out https://help.talend.com/search/all?query=Setting+up+the+CommandLines%27+parameters&content-lang=en
The secondary commandline is only used as failover for the first commandline.
For a better follow up, I would suggest that you open a new thread in the Forum.

I was facing similar problem after applying new license key to talend.
After trying a lot of things , I tried putting new license file in Talend installation directory/Cmdline folder and restarted Talend Command line service.
After this , issue was resolved.

Copying the license file to the command_line directory fixed it for me as well.

Hi,
I also faced the same error like "generator failed command" and as stated earlier I have stopped the commandline and deleted the commandline-workspace and restarted the commandline, but still facing the same issue while generating the job conductor.

We are using TAC 6.2.1. with GIT repository. when I try to configure git with TAC, I am giving my GIT id and password and also I have to provide my id in TAC user setting. Is this good for PROD level configuration?

Thanks

This solution works well for me.

My version of TAC is v6.1.1
