[resolved] Connection to Generator failed (Command Line)

[Anonymous]

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

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.

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.

Pedro
